Comment by Tom Davey

A great writer was felled by an early Punch In celebration of Environmental Science & Engineering Magazine’s 25th year of publication, we are pleased to reprint some of Founding Editor, Tom Davey’s editorial comments.

,

n 1849, a writer suEmitted an article to Punch maga]ine on the scandalous state of London’s water supply. Titled Dreadful Hardships, the article, written Ey a young Charles DicNens, was reMected. Punch, then a new puElication, went on to garner world renown as a humorous maga]ine and celeErated its 150th year of continuous operation Eefore expiring in 1992 and then again in 2002 after a failed revival. Punch not only Eecame noted for the quality of its articles Eut also for the writing sNills of its editors. They included Tom Taylor, author of Our American Cousin, the play AEraham Lincoln was watching when assassinated; A.A. Milne, author of Winnie the Pooh; and Malcolm Muggeridge, a celeErated spy, Mournalist, television celeErity, and one of the most elegant writers in the (nglish language. Punch lasted one-and-a-half centuries – a remarNaEle achievement in the cut-and-thrust world of puElishing where mortality rates for young puElications are high. ,ts circulation declined from a peaN of 150,000 to around 0,000 Eefore it ¿nally expired. %ut the impact of Charles DicNens continues to grow, his reputation enhanced Ey movie and TV productions. After two masterly adaptations in ¿lm of his Tale of Two Cities, the story went on to enMoy great success in a TV mini-series. And every year, hundreds of millions of people watch that perennial favorite, A Christmas Carol. ,ronically, DicNens’ reMected piece, Dreadful Hardships, might have Eecome one of his greatest worNs. The squalor and misery resulting from the water-Eorne diseases that ravaged poor families in those days cried out for the masterly touch of DicNens. Thousands, especially EaEies, were slaughtered Ey deadly Eut little Nnown pathogenic organisms - the germs, parasites, and

a request for hypochlorite to disinfect the water to stay the march of typhoid and cholera? Or perhaps some smug character saying the city could not afford piped water and sanitation to poor districts? <ou thinN this is far-fetched ¿ction? LooN at the facts in Canada. ,n the late 1880s, the incidence of typhoid fever and other water-Eorne diseases was high in Eoth Ottawa and Toronto. Well into the 20th century, deaths from water-Eorne diseases were descriEed as ³astronomical´ Ey the City of Toronto’s 3uElic +ealth Department. ,ndeed, even within living memory, Toronto’s death rates have Eeen higher than those of many maMor (uropean cities. Typhoid ran rampant in Ottawa, Eut as the disease was usually con¿ned to the lower class districts, civic of¿cials showed little concern until epidemics swept across the capital in 1911 and

again in 1912. Almost 2,000 people contacted typhoid, with at least 91 recorded fatalities in the capital. 7he &hief 0edical 2f¿cer of 2ntario, Dr. J.W. McCullough, investigated the ¿rst typhoid outEreaN and Elamed civil authorities for negligence in failing to provide a safe water supply for the capital. A second enquiry concurred that the authorities had Eeen negligent. A report suEmitted Ey Dr. Charles A. +odgetts, a medical advisor to the Commission of Conservation, said the 1911 Ottawa typhoid epidemic ³could have Eeen oEviated had the hypochlorite (disinfection) treatment Eeen installed forthwith´ as recommended Ey an engineering consultant, Allan +a]en. Dr. AlEert (dward %erry, a renowned Canadian water treatment scientist and engineer, was only a youngster when these epidemics were sweeping many parts of Canada. They made an indeliEle impression on him for he was to dedicate his life to the eradication of water-Eorne diseases. When he died in 1984 in London, Ontario, at the age of 90, he was proEaEly the most honoured environmental professional in the world.

Comment by Tom Davey than obey the order to disinfect the town water. Many times Dr. Berry forced councils to clean up drinking water supplies several decades before the modern environmental movement began. As in Ottawa, the diseases were often in working class districts and many civic leaders had little concern for their plight, a familiar scenario in Dickens’ novels. Undoubtedly there were even more horror stories of death and disease in the squalor of London when Charles Dickens submitted his article to Punch in 1849. His penchant for lurid details of squalid conditions, combined with his masterly characterization of pompous of¿cials, would have surely made his rejected article on London’s water supply fascinating reading. Coincidentally, the year that Punch rejected Dickens’ article, a remarkable discovery occurred in Broad Street in London where people were dying of cholera. Not even the science of the day

linked drinking water with cholera, and lethal epidemics were common in those times. But Dr. John Snow deduced that some 90 deaths could be traced to a contaminated well serving the area. He boldly broke the pump handle, preventing people from using the well for drinking water. The epidemic stopped. Dr. Snow’s decisive act is a benchmark in the science of epidemiology. While he did not discover the true cause of the cholera, he proved beyond question that this lethal disease could be transmitted through drinking water. His simple experiment was part of a train of events which in the end controlled the epidemics of cholera, dysentery, and typhoid, the great killers of the day in Europe and North America. Something went awry in publishing when Dreadful Hardships was submitted; it could hardly have been lack of writing talent, for the rejected author became a giant of English literature. Had the writing skills of Dickens been

combined with the scienti¿c prescience of people like Dr. John Snow, the environmental movement might have started over a century earlier. NB. Punch published the now famous Remembrance Day poem, In Flanders Fields, written by Major John McCrae, a doctor and soldier with the Canadian Field Artillery. The poem, which became internationally renowned, had a typically Canadian omission – it carried no by-line.

Water Metering

Cape Breton moves to automatic meter reading

C

ape Breton Regional Municipality, also referred to as CBRM, is the second largest municipality in Nova Scotia. It is located on the eastern side of Cape Breton Island, said to be one of the most scenic islands in the world. As an early adopter of new technologies and practices, the CBRM Water Utility decided to invest in radio frequency technology, specifically a mobile AMR (automatic meter reading) solution, from Neptune Technology Group (Canada). It offered the utility integrated project management services for the supply and installation of its T-10 ProRead equipped water meters, R900 radio frequency transmitters and R900 Mobile AMR System, which includes mobile data collection, handheld reading equipment and software. In 2005, CBRM was fully metered, with the exception of approximately 5,000 accounts. The unmetered accounts in the Pottle Lake service area had significantly higher water consumption than other metered communities in the region. The Water Utility was faced with building a new water treatment plant and correctly sizing it was a priority. As a result, the utility implemented a two-year metering plan that clearly mandated that all accounts be metered. The outcome would also mitigate water loss and institute a homogenous system for water billing. Phased-in migration yields big results With a vision to implement a more efficient system and help support stretched meter reading resources, the utility set in motion a multi-year plan to gradually convert their meters to mobile AMR technology. Neptune has been awarded five consecutive contracts since 2008. Their project team installed over 5,000 meter replacements and 5,000 radio retrofit upgrades. In combination with the universal metering project (Pottle Lake), CBRM now has over 73 per cent of their total accounts reading from Neptune’s R900 Mobile AMR

System. As a guideline, any meters younger than 15 years are upgraded to radio, while meters older than 15 years are replaced. Neptune’s approach to project management is structured around the integration of key service pillars: project management, customer care and public communication, area management and data collection, verification and exchange. Each year the project was directed by Neptune’s dedicated Project Manager, Bill Kelly and supported by its cross functional team that included field technicians, call centre and data administrators, public education specialists, IT and product support. Proven benefits of transitioning In 2010, the utility initiated a transition from the Neptune ProRead encoder register to its E-Coder)R900i. Its high resolution, eight-digit encoding makes leak, tamper and reverse flow detection possible at measurements down to 100 ml. The addition of these value-added flags has proven to be valuable for leak detection and data logging of major issues. This technology has allowed the utility to implement a very successful

active leak program for the Pottle Lake area. It can substantiate minimum nighttime flows for the distribution system and assist in identifying and isolating areas of abnormal flows. Furthermore, with the E-Coder) R900i’s easy to read LCD display, the utility was able to enhance their public education program and introduce these features to their customers. This included “Reading Your Water Meter,” a leak detection kit mailing program, which is triggered by leak flags gathered by utility staff. Through this program, the regional municipality has empowered their customers to be proactive in conserving water, lowering water bills and ultimately relieving demand on the water system. Residents of CBRM were not the only group to experience the benefits of the E-Coder)R900i. The utility has three field technicians who perform meter upgrades and replacements in parallel with Neptune’s service division. The utility’s meter shop has achieved improvements in efficiency when replacing the meters, due to ease of installation made possible by the E-Coder)R900i’s wireless feature. Previously, field technicians were running wire from the ProRead register,

Water Metering usually located inside a basement, to an R900 transmitter located outside the home. The utility’s meter reading group has also achieved operational efficiencies. Until recently, many of the meters were over 25 years old and required manual reading inside the dwelling. Implementation of R900 RF technology and the mobile system has relieved meter readers from the liability and safety concerns of entering customer properties. As an example, one area in the community of Sydney had 4,000 meters that were 25 to 40 years old. This area took three meter readers a total of nine days to read, upload, process and validate the readings. With the upgrade to R900 and Neptune’s MRX920 mobile data collector, it now takes one reader a day to read and upload data into the billing system. The three readers process reads, validate, initiate work orders and perform field investigations over a two-to-three day period. Meter reader functions now extend to include data management processing, initiating work orders, performing field investigations, processing E-Coder flag data and preparing customer service packages. The Cape Breton Regional Municipality Water Utility is on a path to achieve a system wide R900 AMR mobile system. Funding projects of this magnitude can be a barrier. However, the utility opted for a phased-in approach. Eventually, they can even foresee progressing to a pilot project to test a FixedBase System.

Legal Issues

City of Kawartha Lakes loses fight over “unfair” oil spill clean-up Order By John Willms

T

he Ontario Court of Appeal has ruled that the necessities of spill containment and environmental protection can take precedence over the “polluter pays” principle and the rules of natural justice. In assessing the validity of a Director’s clean-up order for a 2009 oil spill in the City of Kawartha Lakes, the Court deemed questions of who was at fault were “irrelevant.” The City, which bore no responsibility for the original spill, was ordered to clean up oil that had spread onto municipal lands and threatened to recontaminate nearby Sturgeon Lake. Since then, the City of Kawartha Lakes has fought a series of legal battles to correct what it considers “a breach of natural justice.” While the City did not dispute the jurisdiction of the Ministry to issue such a “no fault” Order, it argued that “the MOE must have regard to principles of fair-

ness, including the ‘polluter pays principle’, as part of its exercise of discretion to issue such an Order.” The City maintained that the MOE should only issue a “no fault” Order in the event that the polluter(s) cannot or will not comply

with a fault-based Order. The Appeal Court did not agree. In its decision re-

leased May 10, 2013, Justice Goudge writes that, “Evidence of the fault of others says nothing about how the environment would be protected and the legislative objective served if the Director’s order were revoked. Indeed, by inviting the Tribunal into a fault finding exercise, permitting the evidence might even impede answering the question in the timely way required by that legislative objective. (Kawartha Lakes (City) v. Ontario (Environment), 2013 ONCA 310).” The Ministry had issued a preventative Order under section 157(1) of the Environmental Protection Act to ensure prompt remediation and minimize any adverse effects. The Ministry had already issued a remediation Order on the responsible parties, but the

Legal Issues spilled oil had spread onto City property. Therefore, a second Order could rightfully be issued to the City as the party that, “owns or has management and control of an undertaking or a property,” even though it bore no fault for the original spill. The Order against the City was appealed to the Environmental Review Tribunal. However, the ERT refused to consider fault, arguing that the overwhelming purpose of EPA s.157(1) is to protect the environment and that, “questions of ultimate liability, fault and other issues are generally left to arenas other than this tribunal.” On May 28, 2012, the Divisional Court upheld the ruling of the ERT, and the appellants appealed the decision to the Ontario Court of Appeal. While the issues were winding their way through the legal system, the City completed the clean-up of its property at an estimated cost of $470,000. Justice Goudge of the Appeal Court writes, “I agree with the Tribunal and the Divisional Court that evidence that others were at fault for

the spill is irrelevant to whether the order against the appellant should be revoked. That order is a no fault order. It is not premised on a finding of fault on the part of the appellant, but on the need to serve the environmental protection objective of the legislation.” In a separate case before the Ontario Superior Court, the City is tak-

ing steps to recover its clean-up costs (under s.100.1 of the EPA) from the oil company, the insurer, the adjuster, the homeowners, the firm that undertook the site clean-up, the tank manufacturer, the Technical Standards and Safety Authority and the MOE.

No one disputes the basic facts of the case ...

O

n December 18, 2008, an estimated 500 litres of fuel oil were spilled into the basement of the home of Wayne and Liana Gendron. By the time an insurance adjuster visited the property some 12 days later, the oil had already migrated through the storm sewers under the adjoining city road and into nearby Sturgeon Lake. The Ministry of the Environment immediately issued a Provincial Officer’s Order requiring the Gendrons to prevent, eliminate and ameliorate the adverse effects of the spill. Remediation efforts continued “around the clock” until March 20, 2009, when the Gendrons’ insurer refused to fund further off-site work, while continuing with the on-site excavation of contaminated soil and the complete demolition and reconstruction of the Gendrons’ home. Although the lake pollution had already been cleaned up, the ministry issued a preventive Order against the City, requiring it to undertake the remediation of any oil remaining in the culverts and sewers that could recontaminate Sturgeon Lake.

Instrumentation and Control

Making pump station call-outs a thing of the past

I

t’s 2:00 a.m. and a telephone rings in Eckville, Alberta. Rick McKinnon checks the display on his cell phone and sees it’s another high level call-out alarm, from one of the town’s new sewage lift stations. He knows, before he drives there, that the system will be running on floats, instead of the new ultrasonic level controller. McKinnon is the Town’s public works supervisor and has to work out most of the problems that occur in the wastewater collection system. Level control callouts in two new sewage lift stations were costly and straining his resources. Serving a population of 1,100, the Town completed its upgrade project with two new lift stations and forcemains in 2011. Each control system included a non-contacting ultrasonic level controller with Hi/Lo floats as backups. The pumps are variable frequency drive, operated with relay connections to the level controllers for on/off pump control and 4-20mA speed control. Soon after start-up, Eckville operators began receiving call-out alarms from the control systems in both pump stations. The cause of the echo loss problem was hard to figure out, because it was intermittent. The ultrasonic level controls would work perfectly for several weeks, but then call-out alarms would begin again. They first suspected that condensate might be forming on the ultrasonic sensors and causing echo loss. Over several months, operators experimented with instrument settings, sensor positioning and then with baffles and stilling wells to reduce foam and grease build-up on the water surface. Improvements were made, but none of the modifications entirely stopped the call-outs. This problem was not new to Greyline Instruments, who had seen similar echo loss conditions in sewage lift stations before. Their design engineers came up with the concept of a level instrument that operates with an ultrasonic as the primary sensor and any other 4-20mA level transmitter as a redundant or standby sensor. The new model PSL 5.0 Pump Station Level Controller was released at the same time Eckville was

experiencing call-out alarms. McKinnon contacted Carbon Controls of Calgary, to help solve the level control problems. Carbon Controls supplied two of the new Greyline level controllers, plus submersible pressure sensors to be connected to them as a hybrid system. They felt that using ultrasonic, along with pressure sensors, would result in a reliable level control system that would not be affected by foam or grease on the water surface. How it works Pump station level monitoring is a critical process, with catastrophic fail-

ure modes. In a standard collection system, sewage flows to local wet wells, or sumps, by gravity and is then pumped to a treatment facility. Water level in the wet well is monitored and pumps activate whenever the level exceeds set points. Monitoring instrument failure would allow the sewage level to rise and spill into the environment and/or back up into homes. High level alarm switches are typically installed as a backup. Several methods exist to monitor liquid level. Airborne ultrasonic sonar has become the standard level monitoring technology. It offers easy transducer installation and maintenance as they are mounted above and away from the sewage. These sensors are highly reliable, due to modern manufacturing methods. Air sonar uses sound pulses bounced off the liquid surface to compute sewage level. Grease or foam blanketing the surface is one of the few situations which can defeat this level monitoring method. Having an alternate monitoring method which is not defeated by grease cakes or foam, would allow a “second opinion” and not trip high level alarms in case of a temporary loss of sonar signal. An added bonus is that the embedded sonar calibration is used to automatically calibrate the alternate level signal. The two level signals are continuously compared, to alarm the operator if the alternate signal is not responding to level changes. The transition from primary to secondary level signal is seamless and a

Instrumentation and Control display shows the operator usage hours logged, for troubleshooting or maintenance. PSL 5.0 uses a “hybrid” of transducer technologies to provide a redundant level measurement and insurance against level measurement failure. The 4-20mA secondary input, automatic calibration and signal monitoring, together with an easy field retrofit, are designed to solve a specific problem in the sewage treatment industry. Non-contacting ultrasonic level sensors were installed about one meter above the high water level in Eckville’s wet wells. They were positioned with an unobstructed view of the water and where foam, grease and scum were least likely to form. Backup submersible pressure sensors were connected to the Greyline PSL 5.0’s 4-20mA hybrid sensor input and suspended in the sewage wet wells with ¾” PVC conduit. They were mounted a few centimeters below the low water level. Once the ultrasonic and submersible pressure sensors were installed in the wet wells and the system was powered up, the PSL 5.0 automatically scaled the pressure sensor. After one or two on/off pump cycles, the pressure sensor was calibrated and ready to function. Now, if Eckville’s ultrasonic sensors lose signal from foam, or grease, on the water surface, the pressure sensor will take over reading instantly. As soon as the ultrasonic sensor receives new echoes, it

resumes function as the primary sensor. McKinnon checks the systems periodically by referring to the “run-time” reporting screen on each level controller. Pump run-times and alarms are logged automatically, as well as runtime for the redundant pressure sensors. Using the run-time reporting function,

Wastewater Treatment

New weapons for fighting odour in long forcemains By Paul Eybergen and Ken Campbell

W

hen design started on the new Embro, Ontario sewage pumping station and forcemain, everyone knew controlling odours was going to be a fight. Embro is a village of about 1,000 people located around 13 km (as the forcemain flows) northwest of the sewage collection system in Woodstock. The County of Oxford owns and operates all water and wastewater systems throughout the area in which Embro is located. The County undertook a Class EA, which concluded that wastewater from the new communal sewage collection system in Embro would best be pumped to Woodstock, rather than to a new wastewater treatment plant located nearby. There were some significant design challenges for the pumping option. The forcemain had to be oversized to a 200-mm-diameter pipe, as smaller-diameter pipes running such a long distance at the minimum scouring velocity, ended up with unreasonably high friction losses. The volume of the 200-mm pipe over the 13 km was 430 m3. The design average day wastewater flow was only 380 m3/d, resulting in an average travel time of over 27 hours. In the early days

of the system when flows are lower, travel time would be longer — as much as two to three days! This long wastewater detention period was certain to create a lot of hydrogen sulphide and major odour challenges. To deal with odour, a six-point approach was developed: 1. Keep the forcemain full. In addition to a check valve to prevent wastewater from flowing back to the pumping station when the pumps are turned off, a control valve system at the forcemain discharge was designed to close when

Odours could be best managed by concentrating them at the discharge location. the pumps were off, to prevent the forcemain from partially draining out at the discharge end. This would prevent the pipe from being partially drained and re-filled every cycle, releasing foul air discharges at multiple high points along the forcemain. The idea was that odours could be best managed by concentrating them at the discharge location.

2. Use a stripping chamber. Because wastewater was discharging into a gravity sewer system running through a future residential area, it was decided to provide a stripping chamber. Coarse bubble aeration driven by a small blower was designed to remove the majority of volatile odours so they would not be released in the downstream sewers. 3. Air-tight maintenance hole cover inserts. Air-tight sewer inserts were added under the covers to stop air flow and prevent the escape of any odours not removed at the odour control facility. 4. Biofilter. The odour control facility included a fan to draw air from the top of the stripping chamber and the downstream sewers, and send it to a two-stage biofilter. Treated air was then discharged into an exhaust stack at the top of the unit. 5. Swabbing. A swab launch system was included in the pumping station design, to allow swabs to be easily introduced into the forcemain. Using forcemain swabbing for odour control was an approach successfully used by the County of Oxford operations staff on another problematic wastewater forcemain. Swabs remove biofilms that adhere to continued overleaf...

The first four points in the odour control system, as listed above, did their job. The control valve system successfully kept the pipe full and the stripping chamber (lined with an anti-corrosive concrete coating) successfully drove off

heavy concentrations of odours. The biofilter took a little time to commission and get properly adjusted and for operators to become familiar with the system’s functions. Once it was fully operational, it worked well, reducing H2S levels to below detectable levels in the area surrounding the stack discharge. After about six months and with 20% of Embro customers connected, odours started occurring in the vicinity of the

odour control facility and neighbours started to complain. The system was not keeping up. Oxford’s operators started investigating and found H2S spike levels over 300 ppm in the stripping chamber. This concentration not only exceeded the capability of the biofilter, but is dangerously toxic if inhaled and was thus an operational concern. The pumping station wet well operating range, i.e, levels at which pumps start and stop, was reduced, making cy-

cles more frequent but for shorter periods. Makeup water was also introduced to the pumping station wet well to reduce the forcemain turnover time. These steps mitigated the problem for a couple of months, but high H2S levels eventually returned. Through trial and error, operations staff determined that swabbing the forcemain every three months immediately continued overleaf...

In June 2012, the 13-km long, 200-mm-diameter forcemain was swabbed for the first time while the sanitary pump station was in operation. A contractor was hired to launch six 250-mm-diameter foam swabs into the 200-mm pipe, five minutes apart. A 50-mm water service that had been installed at the SPS was utilized to insert the swabs into the forcemain with a specialized launcher provided by the contractor. The swab launching was completed within two hours. The six 250-mm swabs were received three days later at the odour control facility. It was later determined that it was best to leave the control valve open during the last part of the process. This ensured that the swabs cannot be directed to the overpressure relief valve piping, where they could get jammed. The swabs were allowed to enter the maintenance hole immediately upstream of the air stripping chamber. A fibreglass grate was installed before the pipe exited the maintenance hole in order to allow the liquid to continue to flow while the swabs were retained.

Wastewater Treatment reduced H2S concentrations at the stripping chamber to less than 100 ppm. They would then see a gradual rise with spikes up to about 300 ppm, at which concentration the biofilter reached its limit and the next swabbing was implemented. It is anticipated that, as the pumped volume increases and retention time in the forcemain decreases, the required swabbing frequency will also decrease.

“Slow� swabbing During the design of the Embro pumping station and forcemain, the engineer was concerned about how the swabbing could be done. Assuming the swabbing approach would be to keep the swab in continuous motion, a continuous supply of water and/or wastewater up to the 430 m3 pipe volume would be required. The municipal wastewater supply, supplemented by all available water from the municipal water supply, could not generate the required flows. The engineer assumed that water would need

On a few, very cold, windy days in the winter, the biofilter froze up and became inoperative. In these situations, an odour control chemical was injected at the pumping station, which reduced odour at the discharge. This approach was not desirable on a full-time basis, since the cost of continuous application would be substantially higher than the swabbing approach. Chemical treatment costs about to be trucked, or pumped from a local creek (assuming a permit to take water could be obtained). The operator, however, had a much simpler idea. The operator’s idea was that swabbing could be completed by allowing the pumps to push the swabs in their normal pump cycle. The swabs would start, stop and slowly pass through the forcemain, just like sewage in the normal operation. This was a technique that the swabbing contractor had previously demonstrated to work effectively, and it worked in the Embro forcemain.

$30 per day ($900 per month) compared to approximately $1,000 for a contractor to launch six swabs at every event. The County will be working to improve protection of the biofilters from the elements to reduce the chance of future freeze-ups. There are two key ingredients to successfully managing tough odour control challenges. The first is to recognize the challenge and include as many “tools� as possible for the operator to use. The second is a system operator who takes on the challenge and spends time to monitor the odour situation, determining how to make use of all the tools provided in the most efficient manner. Using the range of odour control tools provided, the County of Oxford operations staff have successfully managed to operate the new Embro pumping station and forcemain with only minor odour complaints.

Groundwater provides a new velocity Vq, and a new set of friction losses for the next length of pipe between the perforations. This would require n+1 different frictional calculations for head loss and friction in the length of the perforate pipe. That is just unrealistic and extremely cumbersome. One textbook from the 1960s provides a good answer. It suggested that with a pipe of constant diameter, the head losses through the nozzle were approximately equal to the friction losses equal to about one-third the frictional Àow in the pipe. In scienti¿c terms, the friction head or hf is equal to the value shown in Equation Two. (Hf = (KQo2/L2)* (l-l2/L + l3/L2) :here K is the hydraulic coef¿cient equivalent to the head losses in the total length of the pipe at full Àow conditions L is the length of the pipe, l is the fractional length of the pipe where the losses are occurring, and Qo is the total Àow in the pipe at maximum conditions. Remember that head greater than the hydraulic head on the outside of the pipe is needed. Another way to look at the solution is to perform an analysis across the ori¿ce. In a simple case we have qn = C*Ao2*[2gh]0.5. If the value of C is 0.60 and the value of the large pipe Àow is Q and the individual ori¿ce value is q and the hydraulic head differential between the inside of the pipe and immediately outside the pipe is hd which accounts for the submergence of the pipe. If you set the nozzle losses greater than the pressure head against the pipe plus the pipe friction, the design works. For example, a 3� pipe 300 feet long, needs to distribute 100 gallons per minute through it uniformly. Head losses through the length of the pipe are 4.47 feet of head loss per 100 feet. The pipe is submerged by three feet of water. The total head loss is then 4.47 * 3+3 = 16.41 feet of head or approximately 5 PSIG. If 30 nozzles or ori¿ces are used, each one should take about 3.33 gpm. The nozzle size should be q = 0.60 A2 [ 2gh]0.5 In the proper units q = 7.42*103 cubic feet per second, g = 32.18 ft/ second2 and h = 16.41 ft. This gives A2 as 5.381*10-4 square feet or 0.0775 square inches. www.esemag.com

That translates to a hole of approximately 0.0987 inches in diameter. :ater will then Àow in and out uniformly. &RPSUHVVLEOH ÀRZ Compressible Àow occurs in air and other gases. The formula must account for variables such as initial and ¿nal states and temperatures. As air crosses the ori¿ce it changes temperature, decreasing sharply as it expands from the nozzle. In order to prevent the formation from plugging with ice, change in temperature across the ori¿ce must be accounted for. The equations for compressible gas Àow across a nozzle are a bit different. In general, Equation Two is applicable only for incompressible Àows. It can be modi¿ed by introducing the expansion factor to account for the compressibility of gases. A ¿nal check of gas velocity through the ori¿ce should be done to make sure it does not exceed the speed of sound. It should also be checked for temperature

to ensure that gas vapor which contains water will remain above freezing. This is important for both vacuum extraction and vapor venting horizontal wells (under pressure). The entire program is easily arranged on a spreadsheet and total ori¿ce size, pressure drop and gas Àow can be easily calculated. Using the same essential data, select a drill size and a spacing which is suitable for the length of the horizontal well. A brief calculation of the total ori¿ce size and appropriate area is very straight forward and easily performed. It takes a bit of trial and error to ¿nd the right quantity and ori¿ce size, but is well worth the effort. For example, one installation of 12 lines of 1600 feet each in the Louisiana clays, successfully removed over 100 tons of chloroform and carbon tetrachloride in a six month period. David L.

vault dewatering, but attracted the interest of the environmental services industr\. In 2012, the American Association of Te[tile &hemists and &olorists named :ilson its <oung (ntrepreneur of the <ear, as a salute to the contribution of her ¿lters to the environment and the te[tile industr\. David Molinatti, of S&S Supplies and Solutions, recentl\ noted in the Atlanta Business Chronicle that the ¿lters are being rapidl\ adopted, particularl\ for dewatering utilit\ vaults, because the\ are “a safe and cost-effective method for utilities and municipalities to meet vault dewatering regulations without the high e[pense of using a vacuum truck.´ After the ¿lters became a common product for dewatering utilit\ vaults, the manufacturer, Pure Filter Solutions, was approached b\ Adler & Allan /td., an environmental services ¿rm based in the 8nited .ingdom. The\ wanted to introduce the technologies into the environmental services market. Adler & Allan brought the latest ¿lter technolog\, which incorporated a unique la\er of activated carbon to handle lower-molecular-weight h\drocarbons, to a 1ational *rid converter station for an annual cleaning and servicing of the bunds and bund water control units. Richard Sacree, project manager with Adler & Allan, noted that the project successfull\ reduced the use of vacuum trucks b\ appro[imatel\ 0 and also reduced waste removal and labour costs. “As important as the cost saving was, the additional bene¿t of the reduction in carbon emissions made a contribution to 1ational *rid¶s carbon reduction targets,´ said Sacree. The ¿lters were put to the test again in the winter of 2012 when a gasoline tanker was involved in a vehicle accident in remote Kinross, Scotland. The tanker left the road and overturned, resulting in a large spill of appro[imatel\ 20,000 litres of fuel into a stream.

Oil/Water Separation measures by excavating interception trenches. A vacuum tanker then pumped 1,500 litres of product from this trench, after Zhich the ÀoZ of product stabili]ed. The next day contamination in the standing water was found to have migrated slightly downslope. Another containment trench was excavated downslope of those excavated the previous night and a vacuum tanker removed a large quantity of product. With the approval of SEPA, the trenches were extended and linked with a further trench in order to make the containment of fuel easier. Next, an oil-water separator was used to treat the water in the lowest trench and the separated contaminate was removed by vacuum truck. However, due to the sheer volume of surface/groundwater on-site and following testing and sampling, permission was obtained from SEPA to discharge water from the oil-water separator through Pure Filter Socks to an area of land downstream of the contaminated area. This operation worked extremely well and SEPA even permitted a discharge to the stream via the ¿lters. The result of

using the ¿lters for this application was a 50% reduction in operational costs, an 80% reduction of carbon emissions due to less use of vacuum trucks, and less wear and tear and congestion on the rural roads. Not every spill situation warrants the use of the ¿lters and vacuum trucks will

Collection Systems

Surge anticipator eliminates pipe breakage

T

he District of Central Saanich is a member municipality of the Capital Regional District (CRD) of Greater Victoria in British Columbia. It is a rural residential community with a population of about 17, 000. The District has a medium sized, widely dispersed sewage collection system, dating back to the early 1970s. It sends its sewage to the CRD’s regional wastewater treatment plant. Within the municipal collection system, multiple sewage lift stations pump sewage from satellite stations through forcemains into the regional trunk sewer system and from there to treatment. There is minimal storage capacity within the municipal collection system. One of these facilities pumps sewage through a 300mm asbestos cement forcemain to a sewer siphon several kilometers away. When fluids travel such long distances, there is always the potential for pressure build-ups, from even the slightest changes in velocity. When a sewer main ruptures under these circumstances, it can have significant negative impacts on the environment. It also causes headaches in repair and associated costs and is disruptive to residents. This is exactly what was happening in Central Saanich, due to aging infrastructure and surges from pumps stopping and power failures. The District, in conjunction with the CRD and its consultants Stantec, reviewed options for upgrading the existing facility to address ongoing operating conditions. The recommendation was an anticipating surge relief valve, designed to reduce stress on the pipes. This would prevent bursts and increase the pipe’s lifespan. Singer Valve’s Pneumatic Dynamic Lifter was chosen, as the solenoid operated surge anticipator would still work during power outages. The Pneumatic Dynamic Lifter is a very responsive compact sewage relief valve that can handle high pressures (200 psi or 13.8 bar or higher) and uses standard plant air supply to hold the valve closed. This chamber is fitted with a relief pilot that is also normally closed as long

as the line pressure is lower than the set point. If pressure rises above the set point, the relief pilot opens, causing air in the cylinder to vent. This in turn opens the valve, which operates as a high pressure relief valve. Central Saanich has three 75 hp pumps that each cycle between 30-50 times a day. As the valve operates on every shutdown, it is crucial that its operation is precise and occurs at the right times to prevent surges. Otherwise lines can literally be blown out of the ground. Another of Central Saanich’s problems was surges due to power interruptions. When this happens, all the pumps suddenly stop, resulting in a surge proportional to fluid velocity at the time of the power interruption. This problem is also solved by the Pneumatic Dynamic Lifter with its anticipating surge relief option. This function uses two three-way solenoid valves to put air into the cylinder under the piston, driving the valve open on power failure. This way, when the surge returns to the pump, it is not coming back to a closed system where it can cause damage. It comes back to an open valve where it can be discharged safely back

into the storage well underneath the pump. The main valve needs to be open long enough to handle the initial surge, but not longer, otherwise it will continue to drain the line. To prevent this, the solenoid is on a timer, which the field crew set at start-up. Once the time has elapsed, another solenoid allows air to re-charge the cylinder, closing the main valve. The Dynamic Lifter has been designed to minimize costs and maintenance. The piston and closing speed controls operate separately from the sewage, in a clean non-contaminating environment. Conventional spring-operated valves allow build-up of wastewater residue (dry pack) on the valve’s downstream and exhaust pipe to sump. However, the Dynamic Lifter can easily be opened through the actuator, to flush out these unwanted build-ups. Mineral and debris build-up is kept to a minimum by using premium materials such as heat-fused heavy epoxy coatings on the main valve and a 316 grade stainless steel seat and stem.

The simplified process for immobilization of arsenic as bioscorodite.

Arsenic immobilization Currently, Paques is further developing a patented process (THIOTEQScorodite) for arsenic immobilization, based on work by Wageningen University’s Dr. Paula González Contreras. Arsenic is a toxic element that cannot be reused and large amounts have been collected from metallurgical processes as arsenic trioxide. There is no market for the tons of arsenic released from metallurgical processes. A time-stable discard product is essential. Only scorodite, which occurs naturally as a stable mineral in nature, ¿ts that requirement.

Combining bio-crystallization and aerobic air-lift loop reactor technology has several advantages compared to traditional precipitation tank reactors.

The aerobic process is a new sustainable solution to arsenic removal and its immobilization. In this process, a compact air-lift loop reactor (CIRCOX– technology) is the basis for the production of arsenic-containing crystals, i.e., bioscorodite crystals. Biogenic scorodite production in CIRCOX reactors is the result of a successful balance between bio-oxidation and crystallization reactions. Since 1987, Paques B.V. has gained extensive full-scale experience with more than 30 CIRCOX bioreactors, treating diverse wastewaters. It is expected that the process can be implemented at full-scale in a relatively simple manner. Combining bio-crystallization and aerobic air-lift loop reactor technology has several advantages compared to traditional precipitation tank reactors. Bioscorodite crystals are suspended in an aeration-induced circular liquid Àow. This minimizes scaling and mechanical problems. Crystal retention in the reaccontinued overleaf...

Industrial Wastewater tor is improved by the high density of bioscorodite and large crystals, which are also older crystals and therefore more stable than nascent ones. Harvested crystals are selected by their sedimentation rates, assuring high stability values. Microorganisms play a key role in the production of bioscorodite, precipitating arsenic at 70°C, instead of the higher temperatures and pressures used in autoclaving technology. These extreme microorganisms grow by oxidizing iron, in the presence of arsenic, as free cells in suspension and at low pH values. Operational costs are reduced when compared with chemical precipitation. This is mainly due to the fact that no chemical oxidant is needed. Air is used as the oxidant. Furthermore, formation of gypsum is reduced to a minimum because no seeding material is needed and less neutralization with lime is required. The result is a pure, stable and compact crystalline product. Harvested bioscorodite crystals are large in size, have a high arse-

nic content (30 wt%), low free water content (<3% free water on settled samples), and they have exceptional stability properties based on arsenic leaching values in TCLP tests. These properties enable disposal of the crystals immediately after being harvested. An immediate application of this process is treatment of streams where arsenate is present, such as efÀuents from (bio) leaching operations.

Arsenic stabilization is going to be one of the most important environmental issues facing metallurgical companies when disposal legislation becomes stricter. Converting arsenic into bioscorodite can lower environmental risk and provide important cost savings to the company. Martijn Olde Weghuis is with Paques. E-mail: m.oldeweghuis@paques.nl

Security

Securing your municipal water infrastructure

By Victor Wong

E

lectrical utilities, oil and gas, chemical process and water have been identified as critical infrastructure assets that require absolute protection from a security incident. So why is it that three of these critical infrastructures have rules, regulations and penalties in place to protect them, while water, one of the most valuable assets for human existence, does not? What if your municipal drinking water was compromised, what would you do? In 2007, when Metro Vancouver’s main Seymour reservoir’s water contained high turbidity, the public was asked to boil their water. During that time, there was no potable water for consumers, hospitals, business, industries or even Starbucks! Pandemonium broke out at local stores, when consumers fought for bottled water! Imagine if this natural occurrence was an actual security compromise. How would a municipality handle this issue? Would they even know if there was a compromise? What would happen to consumer confidence? Do you think this only applies to drinking water? How about the Maroochy Shire sewage spill that occurred in Australia in 2000, when over 200,000 gallons of raw sewage spilled in parks, rivers and the grounds of the Hyatt Hotel. This incident was an actual cyber-security incident undertaken by a disgruntled contractor who was working on the Shire’s SCADA system. He had stolen radio equipment, controllers and software to mastermind this security incident. You would think that after so many years of technological advancement and knowledge about security, incidents would have stopped. In fact, there has been a steady rise in reported cyber incidents. The following is a small list of security incidents which occurred in the water community: • Salt River Project SCADA - hacked. • Maroochy Shire Water System, Australia. • Harrisburg Pennsylvania water treatment plant - compromised. • Trojan/Keylogger on Ontario water SCADA system. • Tehema Colusa Canal Authority,

California - compromised. • Denial of service attacks on water system via Korean telecom network. • Penetration of California Irrigation District wastewater treatment facility’s SCADA system. Municipalities’ perspectives on security With so much at stake and so much information available, why are municipalities still taking a reactive rather than a proactive position on security? The following are actual quotes collected when municipalities were asked for their perspective on the issue: • “Large system users such as Metro Vancouver are more at risk than smaller municipalities.” • “We know that the United States has more of these problems and Canada is not targeted. In fact, who wants to hack into the middle of nowhere?” (If your computer is connected to a network, you’re vulnerable.) • “Hackers do not understand SCADA systems, or their equipment.” • “No one knows about my system, so it must be safe.” (Security through obscurity is not a solution.) • “Vendors are just trying to scare us so they can sell more of their equipment”…or not! • “You know, I’ve not heard of any

neighboring municipality that has been hacked, so we’re all good.” (If you were compromised, would you publish this in the local newspaper?) • “Our IT department has got a security policy and they said it was all good, we’ll just use theirs for SCADA.” (IT policies cannot be applied to SCADA directly. One needs to be developed.) • “No one in our organization knows much about security let alone security for SCADA, so we kinda let sleeping dogs lie” (There is a plethora of information available on security. Be proactive and do your own research or, better yet, contact your local associations or the RCMP. So what is going on here? Over the last decade, municipal SCADA systems have seen a significant increase in the use of computer networks to transfer information from control centers to supervisory and corporate IT computer systems. Specifically, most SCADA systems are now using networked process historian servers and expert systems servers to allow users to access real-time data. There are also many other possible business/process interfaces, such as using remote direct file transfer from control devices such as RTUs (Remote continued overleaf...

At the same time, there has been an explosion in the use of Ethernet and TCP/ IP technologies, both wired and wireless, in SCADA. Most SCADA systems now use Ethernet networking, rather than traditional proprietary industrial networks

such as Data Highway or Modbus. Consequently, networks are increasingly Ethernet-based for both IT and SCADA systems. The issue is that complications on IT networks can be passed on to SCADA networks or vice-versa through the IT/ SCADA interface. This can seriously impact SCADA system and network operation and devices associated with those networks. Aside from the potential that data flows

between SCADA system to IT networks could be compromised, the “hacker community” has discovered SCADA systems. How can we protect municipal water systems? To implement a secure water system, municipalities must acquire the right focus in their approach to security. It should not be about adding more technology, such as firewalls, network mitigation and prevention equipment to your SCADA system. The focus should be on people and processes. Why should we focus more on people and processes rather than just throwing technology at it? As a quick example, Company ABC purchases a high-end firewall to protect their SCADA system. However, due to lack of security policies, one of the employees decides to plug in a USB key, or a CD, from a vendor that is loaded with malware. This malware could make its way behind your firewall into the SCADA system. This has happened before. Providing a better security framework for SCADA systems would ensure better reliability and less down time. Municipalities need to develop security policies and frameworks that seek to prevent, mitigate and respond to a security incident. It is not good enough to just borrow or deploy security policies that have been developed for IT. These are often inappropriate for deployment in a SCADA system’s environment. There are, however, certain policies and frameworks from IT systems that municipalities could leverage for SCADA systems’ security. However these policies should be well defined and understood. Traditionally, IT security focuses more on the confidentiality, integrity and availability (CIA) model, whereas SCADA systems focus more on the availability, integrity and confidentiality (AIC) model. Some IT policies involving patch management, such as Windows Update, anti-virus/malware protection, and penetration testing, may work adequately for IT systems, but may seriously affect SCADA system operations. This has occurred in the past, where an operating system patch undertaken by IT staff, shut down the SCADA system before vendors had a chance to test their software against the patch.

Security Remember that appropriate security frameworks will minimize security threats, ensure better reliability with less down time, and maximize continuous service to the community. Where do we go from here? Today, there is a lot of information available on how to develop a security policy/framework for your municipality. Associations and agencies, such as, the American Water Works Association, the Water Environment Federation and their member associations, the Department of Homeland Security in the U.S., the RCMP and Public Safety Canada can provide information on securing your municipal infrastructure. Municipalities should also consider hiring consultants familiar with both SCADA and security systems to assist in developing policy frameworks. In order to provide safe drinking water to everyone, municipalities need to act now! 1. We need to develop more awareness at the municipal management level. 2. Security awareness and buy-in at the management level is critical to the acceptance of developing a security system framework. 3. Municipalities need to identify barriers or impediments to providing protection for our drinking water. 4. Municipalities need to identify new or existing staff who are accountable for making SCADA system infrastructure secure. 5. Look for assistance from provincial

and federal governments for funding security initiatives. 6. Develop education through local and provincial municipal associations and schools and work with law enforcement agencies. If your water system has not been compromised, it is not a question of “if” but

“when” it will be. An even bigger question is: if you were compromised today, how would you know? How would you mitigate or respond to the incident? Victor Wong, P.Eng., is with Opus DaytonKnight Consultants. E-mail: Victor.Wong@opusdaytonknight.com

Water Treatment

Influences on biofilm development and corrosion in watermains By Garry A. Palmateer

C

orrosion of iron pipes in distribution systems can cause three distinct, but related problems. Firstly, pipe mass is lost due to oxidation of elemental iron into soluble ferrous species. Secondly, scale development, which results in tubercle formation, often causes increased head loss and decreased water capacity. Thirdly, the release of insoluble particulate iron, which is essentially iron corrosion by-products in water, decreases the aesthetic Tuality of the water and can result in consumer complaints of red water. Both chlorine resistant and pathogenic microoganisms may enter a distribution system, downstream of the treatment plant, through the following ways: 1. Failed backÀow preventers during a watermain installation or a broken watermain repair. 2. The intrusion of contaminated water into watermain joints when the pressure outside the watermain exceeds the pressure inside. 3. Cross-connections to private shallow wells, cisterns and other sources, which can be contaminated with coliforms and Escherichia coli. Although water is Àowing rapidly through watermains, its velocity at the pipe surface is essentially zero. This allows particulates carrying nutrients, such as dissolved organic carbon, soluble forms of nitrogen and phosphorous and trace elements, to accumulate. Micro– organisms are attracted to these nutrients. The growth of bacteria and fungi on the interior walls of a watermain is called bio¿lm. It occurs, to some degree, on all smooth pipe surfaces, but to a much larger extent on rough pipe surfaces. The attraction and attachment of individual bacterial cells to the pipe’s surface, will result in mixed layers of bacteria and fungi. Eventually, a coating of microbial cells will develop, so that the outer layer of the inter-connecting cells exists far from the pipe surface. These outermost formations tend to break or slough off from the underlying

cells in a very random manner. When a new watermain is connected to an old cast iron, ductile iron or cement-coated iron pipe, the installation process can dislodJe pieces oI Eio¿lm. This often serves to contaminate water samples with coliform bacteria. In addition, the larger inner surface of the new pipe can create water velocity changes that result in a random sloughing of bio¿lm from portions of the inner surfaces of the old main. The complex structures formed by the many types of bacteria in bio¿lm, can serve to protect coliforms, Escherichia coli and pathogenic microoganisms from disinfection, which increases the public health risk. Among the factors that challenge some water purveyors more than others, are Àuctuations in the Tuality of source water. Seasonal changes in water Tuality in Southern 2ntario can vary

dramatically during summer months, when demand for water peaks. In cases where source waters are surface waters, water Tuality diminishes as volume decreases and temperature increases. Warmer waters with increased levels of carbon, nitrogen and phosphorous, can augment bacterial growth in surface waters and bio¿lm accumulation in watermains. Water temperatures above ÛC have been shown to have a major positive effect on the growth of microorganisms in bio¿lm. 2rganic carbon is a key reTuirement for heterotrophic bacterial growth, along with readily available forms of nitrogen, such as ammonia, nitrites, nitrates and other nitrogenous compounds and soluble forms of phosphorous. Trace elements are also reTuired and are found in drinking water sources in abundance. The existence of carbon, nitrogen and phosphorous in a ratio of 100:10:1 is

Water Treatment optimal for heterotrophic bacteria and fungi to grow on the inner surface of watermain piping. Of primary importance is assimilable carbon, which is the measure of organic carbon metabolized by these microorganisms. io lm growth on pipe surfaces occurs where the surfaces are rough, typically as a result of chemical oxidation. This results in the accumulation of particulates that are often coated in nutrients. Attached bacteria can grow on these nutrients, which may be 10 to 100 times more concentrated than in the water passing through the pipe. The depth of the growth in a mature bio lm in watermain piping can reach 200 μm. f the process of bio lm growth is not controlled by disinfection, the diameter of the watermain pipe can become signi cantly reduced, which could cause pumping problems. n order to control bio lm de elop ment and kill any pathogens in old cast and ductile iron water pipes, uni directional swabbing of the distribution system, followed by disinfection with free chlorine, or chlorine dioxide,

with subsequent maintenance through chloramination, is necessary. here bio lm has de eloped to the point that multiple layers of bacteria exist, the types of bacteria begin to di ersify. Anaerobic conditions may de elop under the surface layers of cells. hen bio lm reaches 10 to 20 μm, arious types of anaerobic bacteria, including some opportunistic pathogens, will begin to colonize the actual surface of the pipe. Under anaerobic conditions, sulfate reducing bacteria are able to con ert sulfate in the water to sul de, which is ery corrosi e to iron pipes. The sul de actually electrolytically draws elemental iron from the pipe. At this point, pitting on the pipe surface commences and results in the formation of tubercles. The outer surface of the inside of the pipe, where conditions are aerobic, will be reddish, indicating oxidized iron. Underneath the outer tubercle de elopment, in the anaerobic zone on the pipe surface, a black substance de elops, which is iron sul de and which smells similar to hydrogen sul de. f the

pH is high enough (>8.0) at the pipe surface, hydrogen sul de forms. A n iro icrobial er ices td. has conducted many microscopic exam inations of cast iron watermain pipe samples with extensi e tuberculation. acteria comprised of arious la mentous bacteria, such as iron oxidizing Gallionella and Leptothrix, may be found on oxidized surfaces. Particles 10 to 0 μm in size ha e been found to ha e 10 to 100 bacteria per particle. The arious bacteria identi ed were attached to and underneath the tubercles. t has been suggested that bio lm can cause the accumulation of chloride and sulfate ions on pipe surfaces. Accumulation of sulfate ions can enhance the acti ity of sulfate reducing bacteria. A sulfate concentration of only 22 mg has been demonstrated to stimulate sulfate reducing bacteria. ulfate reducing bacteria produce sul de ions, which strongly attract ferrous ions from the electrolytic corrosion on the pipe surface. As more ferrous ions are attracted to the sul de ions, they form continued overleaf...

Water Storage

Contingency and security in new water supply system

I

n 2011, the Town of Greater Napanee, Ontario, underwent some major upgrades to their water facilities. An evaluation study for the replacement of an aged raw water Àexible membrane tank, had established that the Town, even with its existing elevated steel tank, did not have suf¿cient treated water storage for ¿re Àow, eTuali]ation and emergency as required by the Ontario Ministry of Environment. It was decided that additional treated water storage would provide a safer water supply, should the Àexible membrane tank fail. Timing was very important as the existing water tower only held 14 per cent of the Town’s maximum daily Àow for treated water. As well, the raw water supply coming into the plant had de¿ciencies. R.V. Anderson Associates Limited (RVA) was hired by the Town to conduct an Environmental Assessment (EA) to determine the optimal location for the new treated water storage tank; summari]e design considerations in terms of type, si]e, and operational features of the tank, as well as any upgrades to the existing distribution system; and perform tendering and contract administration duties during construction. RVA looked at several types of tanks, but felt that glass lined steel tanks were

preferable as they were cost-effective and offered the shortest construction time. The Town wanted to get the EA, design and construction accomplished within a year, mainly in the fall and winter. As the new tank location was approximately the same elevation as the existing tank, they chose an above ground tank. :ith the ¿nal decisions made from the EA, the project was ready to go to tendering in the early fall. The tender put out was not typical; it was a weighted evaluation, based strongly on the Tuali¿cations and expe-

rience of the tenderer. Once the contract was awarded to Greatario Engineered Storage Systems Ltd., shop drawings were received almost immediately and any items were addressed. They were quickly reviewed and approved by both the Town and RVA. The project went from EA to commissioning in less than nine months. The tank itself was constructed in approximately two months.

Monitoring

The five essential elements of a modern hydrological monitoring program By Stu Hamilton

W

ater is essential for our physical and economic well-being, but droughts and Àoods are threats that require constant vigilance. In fact, it is dif¿cult to overstate the importance of the availability, reliability and accuracy of data from water monitoring programs. Industry best practices, methods and standards have changed to meet modern demands for water information. There are ¿ve essential elements that water resource managers should consider when updating their hydrological monitoring programs, whether their network monitors a small watershed or an entire continent. These are quality management system, network design, technology, training and data management. 1. Quality management system - A quality management system (QMS) is a set of standard operating procedures that

clear objectives for data quality, service and security that are closely linked with the needs of the end users. Quality is a result of process. These processes need to be compliant with documented standard operating procedures. There are several industry sources for hydrometric standards, including U.S. Geological Survey (USGS) Techniques & Methods, USGS Techniques of Water Resources Investigations, ISO Technical Committee 113 and World Meteorological Organization Operational Hydrology Reports. A commitment to internationally accepted technical standards provides a basis for inter-comparability of data. There should be no systematic differences in data produced by different agencies, or even by different hydrographers within the same agency. The service objectives address end-user expectations, which include accuracy, timeliness, completeness and accessibility of data and reports. There is an increasing expectation that data should be openly discoverable, searchable and accessible. Harmonized standards for data interoperability are provided by the Open Geospatial Consortium. For example, the WaterML2.0 standard provides for the exchange of point-based time series data, processed

Monitoring values, such as forecasts and aggregations and relevant information on monitoring points, procedures and context. Security is necessary because hydrometric data are valuable. There are large capital, human and operational investments in discharge information. The security objectives aim to protect these investments over the life of the data, since any information legacy is vulnerable to neglect, loss and destruction. Improperly managed technological advancements can result in fragmented records and incompatible formats. The Global Climate Observing System Principles provide several best practices for maintaining data integrity when managing time series data. In particular, “the details and history of local conditions, instruments, operating procedures, data processing algorithms and other factors pertinent to interpreting data (i.e., metadata) should be documented and treated with the same care as the data.” Best practices for data curating ensure that it is secure and stored out of harm’s way, that the metadata are com-

plete and that documentation is available for any changes in methods that could potentially affect data integrity. Verifying that the quality objectives have been met is a two-step process: quality controls and quality assurance. Most national hydrometric services have developed their own QMS, but some are choosing to become certi¿ed in the standardized ISO 9000 method. A QMS must verify that the resulting products consistently meet the needs of

end-users. Any departure from expected results should provide feedback, creating a loop of continuous improvement. The needs of end-users change with time, so the QMS must be adaptive. 2. Network design - Network design is an ongoing process with new stations being established, and existing stations being discontinued, as program priorities and funding evolve.

Monitoring inductive, potentiometric, vibrating wire, vibrating cylinder or strain-gauge) and the method of deployment (e.g., bubbler, vented or compensated). For each combination of these technologies, there are numerous vendors and products available. Each product has a performance speci¿cation, that can be characteri]ed by an error band, hysteresis, resolution, sensitivity and time constant. Hydrometric network operators must consider several additional factors: • Reliability requirements: an acceptable mean time between failures. • Accuracy in the deployed setting: the blanking distance of some acoustic 'oppler current pro¿lers ($'CPs), for example, may be too great to correctly measure discharge for some stream geometries. • Cost of site access: for remote sites, the incremental costs of acoustic Doppler velocity meters ($D90s) for use with an index-velocity model may be easily recouped by reduced site visits. • Local site factors: high sediment transport, algal blooms and river ice

are all factors against deploying expensive submersible technology. • Instrument sensitivity and precision: relates to the time and effort spent on post-processing of the data. • Training and familiarity: limiting the variety of products deployed in a region can greatly reduce both the training burden and the likelihood of errors caused by a lack of familiarity with a speci¿c device. There are many factors that affect the total cost of ownership of technology. These include the initial capital cost, ¿eld calibration and service frequency requirements, unscheduled ¿eld visits to repair or replace, time and effort spent on corrections and post-processing of the data, data lost due to sensor failure, amount of data degraded by high uncertainty and supplies, such as compressed gas and power. 0oney saved at the time of purchase can be easily exceeded by operations and maintenance costs. Low-cost monitoring equipment does, nonetheless, have its place. For example, in monitoring a high-risk location, one needs to get as

much data as possible before the sensor is inevitably lost or destroyed. Telecommunication technologies offer a signi¿cant improvement in data reliability as a result of real-time station health monitoring and improvements in the timing of stream gauging activities. 4. Training - No investment in technology can compensate for poor decisions in data collection and data handling. Errors through procedural blunders are dif¿cult to detect and correct in data post-processing. Training accelerates the rate that competencies are gained, reducing errors. Stream hydrographers must be skilled in many disciplines to be truly effective. The measurement of Àowing water is a sophisticated application of science and engineering principles. Decisions made in the ¿eld and for data interpretation, require a basic understanding of physics, chemistry, biology, hydrology, hydrodynamics, Àuvial geomorphology, math and statistics. continued overleaf...

Monitoring Additionally, the installation and operation of hydrometric monitoring equipment requires diverse skills. The stream hydrographer must make decisions to limit adverse environmental effects and to preserve both personal and public safety. In-house training and mentorship, as well as external training options should be considered. Some national hydrometric services such as the USGS, offer courses to the general public. Short courses in hydrometric methods are also available from hardware and software vendors, various colleges and UNESCO. Some useful, if limited, online training resources include USGS Surface Water Training, World Hydrological Cycle Observing System, University of Idaho, Humboldt College and Comet Training. 5. Data Management - Hydrologic data are complex. Stream hydrographers are responsible for storing, validating, analyzing and reporting on vast amounts of water data. Specialized hydrologic data management systems are commercially available to meet the evolving needs of hydrologists and to support current industry standards for water information management.

One important role of the data management system is to establish the defensibility of the data by providing evidence of compliance with the quality management system. This means the system must preserve the full m hhistory of the data, inccluding who did what, when, how and why. w As a best practice, rraw data must be presserved intact and all cchanges must be recordeed and reversible. This eensures that data can be rrolled back in time to sshow exactly what edits, ccorrections, approvals oor notes were applied at aany point in time. This is particularly important when dynamically publishing data in real-time. The complete data processing history supports peer review and supervisory control. This history con¿rms the second half of the quality management mantra: “Say what you do, do what you say.” Hydrologists must manage many types of data, in all kinds of formats. All of this data and supporting metadata should be consolidated and managed as a secure, coherent collection. The best solutions support relational queries of this data collection. Web service connections to this database mean that data and metadata are accessible from anywhere, at any time. A modern hydrometric monitoring

system delivers data dynamically in real-time. The best data possible are continuously available. This means that end-users bene¿t as soon as new data are appended, erroneous values are ¿ltered, corrections are applied, rating curves are updated, or shift corrections are applied. The best solutions also provide end-users with informative metadata about the quality and status of the data. Data can be ¿ltered based on the state of the data in the QMS process. Archival quality data are clearly identi¿ed and “locked” from further editing. Automated noti¿cations provide timely warnings about hydrological events and alert hydrographers to any faults or station health indicators that require immediate attention. Automated data correction algorithms censor invalid values and correct persistent and/or predictable errors in real-time, eliminating onerous and repetitive tasks. Automated reporting provides high-value data products to water resources professionals and decision-makers on an event-driven or scheduled basis. The best solutions for developing and validating rating curves are engineered from basic hydraulic principles. The full suite of information gathered in the ¿eld is relevant to the calibration process, including: site photos, cross-sections, ¿eld notes, measurement quality, control conditions, historical ratings and the time series of stage data. Modern solutions for managing shift corrections include the inspection and interpretation of ¿eld

Wastewater Treatment nels”, explains Vlad Petran, Manager of Wastewater Treatment, Capital Works, Region of Peel. Petran was formerly with AECOM Canada Ltd., the company that designed the system. During the initial design phase of the Lakeview project, IPEX worked with designers to introduce its Guardian™ Vinyl double-containment system. It is comprised of 2-inch Xirtec®140 Schedule 80 PVC carrier pipe inside a 4-inch Xirtec140 Schedule 40 PVC containment pipe. To reduce installation and maintenance costs, a patented Centra-Lok™ design allows the system to be installed in 20-foot lengths, while keeping the carrier pipe perfectly centered inside the containment piping. IPEX also helped to ¿nd the most economical way to design the system with expansion joints to accommodate seasonal temperature changes in the tunnels Maple Reinders Constructors Ltd. of Mississauga, Ontario, installed the Guardian system. Their Project Manager, Lyndon Grovum coordinated onsite training by IPEX for piping installers to emphasize proper solvent welding and other installation procedures prior to the job.

created using clear PVC S40 pipes, as plant operation staff were concerned about detecting any leaks in the system. To provide extra peace of mind and a worry-free system, IPEX provided clear tubes at visible low points in the system where potential leaks would be noticed.

These detection points are inspected on a regular basis. The system is working as intended and no leaks have been experienced, since it was installed in 2009. For more information, E-mail: Paul.Agapito@ipexna.com

Mercury Removal soluble mercury levels to the required limits as set out by the Ohio EPA. The Elyria plant is an older secondary wastewater treatment facility that discharges into the Black River, which in turn Àows into /ake Erie. This river is considered an environmentally sensitive area, supporting recreational activities.

It was discovered al-time and on-site. They found that one that by employing a Àuidized bed during kilogram of DioZorb could capture 100 the reaction phase, a much larger volume grams of mercury and that it was effective

at reducing mercury levels to 1.3 ppt. Results of this pilot plant study are being submitted as part of an application for the evaluation of this technology by the Ontario Ministry of Environment. Zorbtech has calculated that one kilogram of DioZorb could treat some 379,000 cubic meters of wastewater. The company believes its treatment technology is a very signi¿cant and cost-effective breakthrough in the treatment of wastewaters containing soluble mercury. Diozorb may also have the capacity to remove other toxic metals from wastewater streams including copper, barium, arsenate, lead and iron. These metals are often still being discharged into the environment, as most treatment technologies cannot remove them from wastewater. For more information, E-mail: info@zorbtech-environmental.com

ES&E NEWS In 2010, the City awarded a contract for a water main installation along several streets in Ottawa to Colautti Construction Ltd. For dewatering required by construction, a permit to take water was issued to the City that required a number of conditions including turbidity testing. Following reports in August 2010 of possible impairments to Stillwater Creek as a result of drilling work, a ministry investigation found the company was responsible for a discharge of sediment into Stillwater Creek. Although there was no evidence of any actual impact to ¿sh in Stillwater Creek, sediment discharges can adversely affect ¿sh and benthic organisms. The City was also found to have not been conducting the required turbidity testing.

Water treatment equipment and flooding Alberta Health Services recently alerted the public to the fact that Àood waters can carry pathogens, viruses, and bacteria. This is especially so if sewer backups have occurred within the building during the Àood. If they have a water treatment device, such as a water softener or iron ¿lter, which has a direct connection to the building’s potable water supply, that was completely submerged in the Àood water: the water treatment device needs to be isolated from the water supply as soon as possible; and, for some older models of water softeners there may not be a bypass for the unit. Therefore it should be completely disconnected from the plumbing. If the water treatment device was not completely submerged, it needs to be sanitized in order to ensure the potable water in the building remains safe. If the public have a drinking water treatment device, such as a reverse osmosis or simple ¿ltration system and live in a community that had a boil water order in effect, it is also recommended that they sanitize any other water treatment continued overleaf... www.esemag.com

New Saskatchewan RO plant The town of Cupar recently opened its new reverse osmosis water treatment plant. It includes a demineralization system and provides the community with drinking water that exceeds provincial quality standards. The project also saw upgrades and improvements to the raw water system, site grading, road improvements and a lagoon expansion. Funding for the approximately $7 million project was a collaborative effort among all three levels of government and SaskWater, a crown water utility. The Town of Cupar contributed more than $550,000. The water treatment plant is owned and operated by SaskWater, which will invest approximately $3 million in the project. In addition to certi¿ed operators, SaskWater has also installed a new SCADA system to monitor key points in the water supply and treatment system. Len Kallichukm, Mayor of Cupar, said the reverse osmosis plant has caused most homes to stop using water softeners and that residents no longer need to buy bottled water. www.gov.sk.ca

The global market for systems designed to disinfect water and wastewater totaled about $1.94 billion in 2012 and should grow to $2.96 billion in 2019, according to a recent study by U.K. based market research ¿rm Frost Sullivan. The study analyzed the disinfection systems markets in the Americas, the Middle East, Africa, the European Union and the Asia-3aci¿c region. It included chlorine disinfection, ultraviolet treatment, advanced oxidation processes, ozonation and electro-chlorination, among others. The market for disinfection is growing rapidly as increased industrialization and globalization require more extensive water reuse, Frost Sullivan said. *lobally, continued overleaf... www.esemag.com

British Columbia carbon neutral for third consecutive year British Columbia released its annual carbon neutral government report on June 28, and 2012 marks the third year in a row that the provincial public sector has achieved carbon neutrality Carbon neutrality is about achieving net-]ero greenhouse gas emissions Even with the best efforts to reduce *+* emissions, it is dif¿cult - if not impossible - to get to ]ero emissions To be carbon neutral, public sector organizations reduce emissions as much as possible each year, measure any remainder and purchase an equivalent amount

of reductions offsets to get to zero For 2012, the provincial public sector created 845,211 tonnes of GHG emissions 2f this total, 2, 1 tonnes do not require offsetting under regulation The total offset investment was $18,807,450 for 752,2 8 tonnes of GHG emissions The B C government¶s commitment to carbon neutrality covers the entire provincial public sector including government of¿ces, schools, post-secondary institutions, Crown corporations and hospitals www newsroom gov bc ca

ES&E NEWS tia has had contaminated sites regulations. Prior to this, direction for cleanup of contaminated sites was given through policy and guidelines. The new regulations were developed with key industry representatives and address most of the auditor general’s recommendations on contaminated sites in his 2010 report. There are two levels of cleanup under the new program: limited and full property remediation. A limited remediation allows property owners to remove contamination or leave it, under very controlled conditions that reduce risks to people and the environment. A full property remediation means property owners must remove all contamination. While this can be more costly, it provides greater assurance to property owners that they will not face enforcement. www.novascotia.ca

land and Labrador, to improve municipal infrastructure through the completion of upgrades to the town water system. The initial 1.2 kilometre section of piping was completed during the ¿rst phase of the project in 2012. The second phase will see the completion of the transmission main upgrading including the installation of new water mains to replace the aging piping system that is currently in use in the town. The overall project calls for nearly three kilometers of new transmission main. In 2012, the Provincial Government allocated $130 million over two years for municipal capital works projects throughout the province. Funding for this project is cost-shared based on population, with the Provincial Government providing 80 per cent of the total, and the Town of Bonavista contributing the remaining 20 per cent. www.releases.gov.nl.ca

Energy savings through appliance efficiency

equipment, such as elevators, icemakers, and MRI machines, use 7.8 quadrillion Btus each year, which is more than the primary energy use of Mexico, Australia, New Zealand, or 200 other countries. The ¿ndings come from a new report, Miscellaneous Energy Loads in Buildings, released by the American Council for an Energy-Ef¿cient Economy. The good news is that these devices could be made to use 40-50 per cent less energy with existing technology, according to the report lead author Sameer Kwatra. If consumers upgraded to the most ef¿cient products on the market today, as much energy as Argentina uses in an entire year could be saved. All together, these devices are referred to as miscellaneous energy loads, or MELs, because they do not ¿t into traditional energy-use categories such as refrigeration, HVAC, or lighting. This diversity has meant that attempts to increase MELs’ energy ef¿ciency have varied, with some products having very little or any ef¿ciency measures in place.
