Reader Feedback Dear Mr. Davey: Your Editorial Comment(Page 9 November issue, ES&E) was read by our group with resounding enthusiasm. It strikes to the point in every aspect of our business. This topic has come up frequently in the past few months with many of our clients and their buyers. We must continually remind all of them of the advantages of using the best and brightest firms. We would like permission to copy the entire editorial for use in our contract nego tiating discussions with our present and fu ture clients.

Robert K. Maier, P.Eng. PUMA Engineering Inc. Dear Editor:

I am writing on behalf of the Pictou Har bour Environmental Protection Project, a community based environmental improve ment group. We were impressed with the Water Treatment article by V.G. Borch, (President, Associated Engineering), in the September 1995 issue ofEnvironmental Scienee & Engineering and would like to have pennission to distribute copies at a commu nity water conservation promotional event at our local shopping mall. The article would be very helpful in our efforts to encourage

Dear Tom:

Re: Political Expediency Has Become More Important Than Environmental Science Prof. Hummel makes some interesting points in his article of November 1995. I would

just like to comment on a few of them: • He states that the assumption now is that Nature is benign and only man (and his in dustry) is evil. This assumption itself con tains an assumption — that there is a real di chotomy between man and nature. He be lieves that there has simply been a shift in emphasis(now man is bad, nature good). He does not question the underlying dichotomy. There is no self respecting ecophilosopher (or otherwise)that would still recognize that this dichotomy is anything but a myth. Na ture and Man are not separate rival entities to be labelled good or bad, but are rather intimately related. Incidentally, who said Nature is benign? This is just as erroneous as the long held belief that Nature is savage, "red in tooth and claw", and needs to be

tamed (civilized) by humanity. A more ac curate description would be that Nature is indifferent. But this brings up another point: why is there such a need to pigeon hole Na ture and create US vs THEM attitude?

• A second assumption, that follows from and is related to the first, is that there is a

conservation.

rivalry between technology and nature. It

J.D. Kyte, Manager of Public Affairs

seems to me that both sides of the divide

Sort Maritimes Limited

(those that are staunchly pro-technology at

all costs and the so-called environmentalists) are wrong. Technology is simply a tool. It is not an evil, but neither is it entirely good. Why must it always be one vs the other? If the rivalry is eliminated (as it must because the underlying assumption is faulty)then the argument collapses. • No one should argue the point that drink ing water is better now than it was one cen tury ago. Some forms of pollution and their impacts have indeed been reduced. But other forms have grown. One century ago I could swim virtually anywhere along the Lake Ontario shoreline. I would think twice about

it today. For those who doubt that the wa ters we live with are contaminated, I would recommend a 1991 Government of Canada

publication entitled Toxic Chemicals in the Great Lakes and Associated Effects. •Prof Hummel states that "our students, even

though they should be scientifically literate, absorb belief systems rather than learn chemistry or biology. They must learn that science and technology are the solution to our problems, not the causes." Isn't this last sentence a statement ofa beliefsystem? Try substituting the word science in the sentence with any major world religion. The mean ing and intent of the sentence does not change. Are we to swallow it whole with out argument? It seems to me that if stu dents absorb the last sentence as written,then they are absorbing a belief system —are you

Reader Feedback not arguing against just this situation? â&#x20AC;˘ I am not sure what your anecdote regard ing the English moth and its changing col ours,from black to white, was meant to show. Of course, it went from white to black (through the process of natural selection) originally because of uncontrolled techno logical and industrial advances which black ened the trees with soot, and only with changes in the industrial base did the white moth come back in areas of its former pre dominance(again through natural selection). I guess the lesson is that what technology giveth, lack of the same technology taketh away? The reporting of the river that could be smelt from a mile away or which gave off gas that would bum with flames reaching 14 feet in height was interesting. One century ago? Remarkable how the more things change the more they stay the same. It re minds me ofthe situation that existed only a short time ago in Cleveland when its river caught fire. What does the author think caused such horrendous phenomena? The answer is rampant disregard for the impact technology can have on natural communi ties. Has so much really changed?

Woodstock, Ontario, is the site of one of the first fine-bubble aeration systems in Canada. When the new fine-bubble system was installed in 1978 there had been very little operating experience to gauge the efficiency of oxygen transfer through the new air diffusers, so air

blowers were sized with plenty ofmargin. Fail ure would have been disastrous and regula tion reinforced a conservative attitude.

However, fine-bubble aeration is more

efficient than it was first expected to be.That finding, in addition to other efficiencies at Woodstock resulting from sewer separation programs, has meant that the original air blow ers installed at the wastewater treatment plant provided more capacity than was needed. In fact, they were able to deliver almost double the maximum required flow. Unfortunately, with air blowers ofthe type that was available in the late 70s, you can't just turn down the volume. At 75 per cent of their capacity, they begin to deliver pressure surges and their energy efficiency drops. Since the original installation, air blower technology has improved. Not only are blow

Some ofBritain's top TV executives now think they were 'had' by Green peace and they blame themselves, not the activists. Executives at the 1995 Na

tional Television Festival in Edinburgh said that broadcasters were 'bounced'

into giving Greenpeace favourable cov erage in its successful campaign to pre vent the Brent Spar being dumped in the ocean.

Greenpeace's media offensive — in cluding the provision of dramatic film footage of its invasion and occupation of the Brent Spar — resulted in one-di mensional coverage by BBC TV and its commercial counterparts, delegates were told. Richard Sambrook, the editor of

BBC newsgathering, said "I think in some sense over Brent Spar we were 'had' we need to wake up. There was never enough distance between our selves and the participants. Greenpeace had spent approximately £350,000 ($700,000 CDN)on TV equipment and feeds,far more than the BBC could have afforded."

Industry Update Can shampoo dilute sperm count? A common shampoo ingredient could be a possible factor in the apparent decline of sperm quality in many countries. While highly controversial, the theory is getting in ternational attention. Scandinavian research

ers say chemicals known as alkyl-phenol ethoxylades, used in shampoos and many other products, can act like the female sex hormone, estrogen. Jorma Toppari of the University of Turku in Finland says boys exposed to such chemicals before puberty could suffer disruption of their hormonal processes.

Research interest in male reproductive health has surged following studies indicat ing that sperm counts in several countries have declined dramatically. Toppari said alkyl-phenol ethoxylades are used in shampoos, soaps and cosmetics. "These are compounds that are not toxic...hut they have these hormonal activities and that's why they are of great concern."

Saskatchewan residents are well aware of

what happens when you build on dry clay soils. Any construction blocks the normal process of evaporation and the soil swells like a sponge. Buildings and roads con structed on spongy soil become distorted and cracked, endangering people. "Saskatchewan engineers have become world leaders in dealing with this type of soil, because they have had to learn to build on it," says Del Fredlund a researcher at the University of Saskatchewan. With the support of the International Development Research Centre (IDRC), the University is working in both Kenya and China to transfer the technology and exper tise to these countries.

In China,expansive soils are often called 'the hidden disaster', causing more that S15 billion in damage by cracking walls, destroy ing buildings and forcing people to move. The University ofSaskatchewan has worked extensively with the Chinese to provide ad vice on what revisions should be considered

for their building code. The code applies to exploration, design, construction and main tenance of any building constructed on ex pansive soils. The code will have a direct impact on people who live and work in build ings of one to three stories. In Kenya, roads have often been de stroyed within a few seasons because of ex pansive soils. It makes it difficult for farm ers to bring produce to market, or anyone else who uses the highway system. The University of Saskatchewan has been suc cessful in providing training for Kenyan civil engineers to do appropriate field tests, and to measure and interpret the results to help design better roads.

He had been working with highly flammable materials that were improperly identified and in an area that had not been made safe for the mixing of poten tially explosive substances. The accident occurred on his third day on the job and he had not received any training on the hazards of the chemicals he was working with.

Pro-Shield had pleaded guilty to charges of: •failing to carry out a process, which could result in the explosion of gas, vapour, dust or fumes, in an area that was safe for han dling explosive products; • failing to instruct a worker in the hazards of working with such products. The company's owner, Gary Mandell,had also pleaded guilty and was convicted for failing to ensure the work was done in a safe area.

New scrap rubber recycling technology STl-K Polymers America, Inc., Custom Cryogenic Grinding Corp. (CCGC), and Praxair, Inc. have announced an agreement to commercialize and market a new technol

ogy for devulcanizing scrap rubber. It is said to be a cost-effective, environmentally friendly way to help create waste-free rub ber-products factories by recycling rubber scrap into a variety of products such as tires, retreads, hose, belts, mats, footwear, and mechanical rubber goods for the automotive and other industries.

According to the Rubber Manufacturers Association, about 113,000 metric tons (125,000 tons) of rubber factory waste is burned or buried each year in North America.

STI-K Polymers America developed the pat ented devulcanizing process trademarked De-Link. CCGC, an industrial plastic and rubber recycler, brings years of cryogenic grinding and processing experience. Praxair provides expertise in supplying liquid nitro gen, as well as extensive cryogenic grinding technology.

The plant, the first factory scrap rubber recycling facility to be built in North America, will provide customers in Canada and the U.S. with grind ing and devulcanizing services for their waste rubber, enabling them to re-use it in their own products. CCGC will also grind and devulcanize rubber from other sources for

resale on the open market.

Manufacturers producing rubber scrap (transfer pads, flash, scorched compound, buffing dust, etc.) can now divert this mate rial from landfill and send it to CCGC for

grinding and devulcanizing. Manufacturers can then replace virgin rubber with devulcanized compounds at considerable savings. They can also obtain a license from STI-K Polymers to use the process for captive devulcanizing of recycled rubber crumb.

sewage spill at service centre Shell Canada Products Ltd. of Calgary was fined $160,000 plus a 20 percent victim sur charge in Cobourg, Ontario for the Febru ary 1994 contamination of the water supply at the Shell Service Centre on Highway 401 in Murray Township near Trenton. The Court imposed a further contribution of $240,000 to be made to the Lower Trent

Region ConservationAuthority, bringing the total penalty to $432,000. The company pleaded guilty to a violation ofSection 14(1) of the province's Environmental Protection Act.

On February 20, 1994, sewage dis charged from a septic tank into a stormwater ditch and entered the wells serving the serv ice centre. The water supply system was shut down on February 23 and the centre put on bottled water until the system had been dis infected.

The Ministry ofEnvironment and Energy became aware ofthe incident in April 1994, following complaints of illness from travel lers who visited the service centre the day of the sewage overflow. Following an investi gation, the Ministry laid charges under the Environmental Protection Act for discharg ing a contaminant that causes, or is likely to cause an adverse effect.

Flow metering, cont'd. To minimize the errors in a flow meter

ing system, all components within the sys tem should be calibrated and evaluated sepa rately. The installation, piping and primary elements should be internally inspected, maintained and cleaned regularly to mini mize errors due to sediment, growths, and wear. The primary element operating error can be established for use in calculating sys tem error. Hydraulic sense lines should be inspected and cleaned or flushed regularly to remove gas or sediment buildup. Another consideration when evaluating an existing installation is the age ofthe equip ment. Many flowmeters manufactured re cently have greatly improved electronic tech nology that usually translates into improved accuracy when compared with older instal lations.

Finally, the system error for the flow metering system can be obtained from the individual errors found from the inspection, measurement, and testing work. Figure 3 is an example of overall metering system ac curacy when all errors are considered. One of the most interesting things this shows is that there is often a range offlows where the error is low (and accuracy is high), but that range does not necessarily coincide with the range offlows that is used. Frequently, mu nicipal design practice allows for systems to be in service many years, and the design flow is often much greater than the average flow in the early years. Sizing a metering system for flow in the year 2040 and expecting it to be accurate when the flow is only 10% of full scale is overly optimistic. The fourth problem noted was the inter nal state ofthe primary device. A clean me ter is better than a dirty one. Almost 30% of the metering systems tested had cleanliness problems that affected accuracy. To assess

Raw water flowmeter inspection.

the effect of meter cleanliness, one 16-inch venturi meter was tested at Ontario Hydro's flow metering laboratory before and after cleaning. The growths inside the tube aver

aged 0.75 inches high, and caused an appar ent flow that was almost 3% higher than af ter cleaning. The first photograph shows the sort of bizarre growth found in a large venturi tube used for revenue metering. The tuber cles ranged from 0.5 inches to 1.75 inches.

Filtered, treated, water can also produce tuberculation and growths in watermains. The second photograph shows a 36-inch venturi that had been used for metering raw water for twenty years without cleaning. Inspection of large flow meters can bring you into unusual situations that the standard textbooks rarely mention. For example,open the manhole and remove the snakes resting peacefully in a nice dry cool chamber. Or open the manhole to find that the meter is

cur when the metering section is removed. Remove bolts that have been in place for many years, and roll out the meter section for inspection. After inspection and meas urement, clean the meter; install new gas kets; disinfect the line; pressure test the re placement; and finally put it back into serv ice. The typical time taken for this exercise was 7-10 days because work could only be gin after the morning rush hour, and had to be completed each day before the evening

rush hour.

Removing a meter for inspection and/or cleaning is preferable to in-situ inspection. Normally a one or two-person job for a small meter, the in-situ inspection ofa large distri bution system flowmeter can be a logistical nightmare, and an expensive and time-con suming exercise. First, block off part ofthe

Older metering installations may pose their own special problems where the flowmeter has to be removed for inspection and cleaning. In one case, there were con cerns that removing the meter from the pip ing could cause the meter chamber to col lapse as the pipe appeared to be an integral part of the meter chamber structure. Providing a bypass line so that a meter can be taken out of service for inspection and cleaning is well worth considering. The alternative may mean shutting down the only

road or intersection at the meter chamber.

Remove the manhole cover, pump out the chamber, ventilate it and test the air to en sure workers can safely enter. Isolate the

piping section to ensure no leakage will oc

ments for the service crews!

To summarize, don't be surprised if your flowmeter is less accurate than you expect. The basic rules for getting value from a flow metering installation are simple: • decide what accuracy is needed, and whether a flowmeter is needed; • know the true operating range that will be used when the meter is in normal service;

• decide what type of meter best fits the flow range and accuracy needs; • install the meter and accessories properly,considering the future needs for inspection, etc.; • maintain the accuracy and performance by regular inspection, mainte nance, and calibration of all components of the metering system. Happy metering. 10

Wastewater Nutrient Removal

Calgary uses submersible mixing technology in biological nutrient removal

Submersible mixing technology is

being used more and more in municipal and industrial appli cations. One of the leading municipal applications for submersible mixing technology is biological nutrient removal(BNR). BNR is an enhanced natural process that requires no additional chemicals for nutri ent removal. In BNR, the primary effluent wastewater is mixed with microorganisms that consist largely of bacteria. These mi croorganisms, which are a natural part ofthe wastewater, break down the organic solids by eating the solids for energy. In this criti cal part of the process,in which the microor ganisms must be in continuous contact with the food particles, the mixing must be just enough to prevent stratification by resuspending solid particles and preventing them from settling at the bottom of the tank, but gentle enough to avoid shearing apart the floe. Ofthe three wastewater treatment plants in Canada using the BNR process(all ofthem located in the West), the largest is the Bonnybrook WastewaterTreatment Plant in Calgary,Alberta. Bonnybrook is one oftwo treatment plants in that city, the other being the Fish Creek plant. It serves the area north ofthe Glenmore Reservoir(Fish Creek serves the area south and east ofthe Reservoir). The entire sanitary sewer system has a 2,920 kilo metre pipe network and 28 lift stations.

Bonnybrook was built on the banks of the Bow River in 1932. The original plant, which relied on primary treatment through sedimentation, could treat 72,700 cubic me tres (16 million gallons) of wastewater per day. In the mid-50s, the plant was expanded to handle 213,000 cubic metres (47 million gallons) of wastewater per day. In 1968, Calgary began secondary treat ment by removing non-settleable organic materials via biological processes. Construc tion on these secondary facilities was com pleted in 1971. This was followed by an other expansion to accommodate tertiary treatment in the form of chemical phospho rous removal in 1982. A subsequent expan sion in 1985 doubled Bonnybrook's capac ity to 450,000 cubic metres per day. Calgary's master plan in the early '90s called for a further expansion to add ultra violet disinfection, ammonia control, and biological nitrogen/phosphorous removal (BNR). Completed in 1994 at a cost of$100 million, this expansion increased the capac ity to 500,000 cubic metres per day. This latest expansion at Bonnybrook in corporated Flygt 4600 submersible mixing technology in the aerobic zone of the BNR process because the project engineers felt that submersibles offered a number ofadvantages over traditional mixers.

Apart from the fact that 4600 mixers are compact, direct-drive units, their main ad

vantage over conventional mixers in a facil ity like Bonnybrook is flexibility. Once they are installed, conventional mixers are fixed. Not so with 4600 submersibles, whose flow can be directed in any direction to minimize hydraulic losses and maximize the amount of energy utilized for mixing. Explains engineer, Tony Altavilla from Flygt: "The 4600 is a new class of mixers. They provide the user with much greater flex ibility in adapting the mixing to the geom etry ofthe tank. Bonnybrook is our first in stallation of 4600 mixers in biological nu trient removal. But we have installed these mixers in other facilities where the channels

are long and narrow. In these applications, this class ofsubmersible becomes even more efficacious because the user can direct the

flow in the proper direction to minimize the hydraulic losses. No energy is wasted in sending a jet against a wall." Bonnybrook also uses Flygt submersible 'Banana Blade' mixers in the anoxic zone of

the BNR process. These mixers, which run at low speed, produce very low turbulence on the surface and therefore draw in a mini

mal amount of air. They also consume very little power compared to conventional mix ers. The latest expansion ofthe plant was codesigned by Reid-Crowther & Partners Ltd. and by Stanley Associates Engineering Ltd. For more information, Circie reply card No. 181

Trenchless pipe rehab

By Flemming P. Jespersen*

City of Toronto chooses trenchless for downtown sewer rehabilitation

TheCity ofToronto has developed a reputation for stringent per formance and quality specifica

technologies after exposure to a number of sewer rehabilitation processes. When it was time recently to reline sections ofthe busy downtown area of Adelaide Street West,the City awarded the contract to InLine Technologies Inc.(The Canadian licensee ofInLiner USA®).

town Toronto. The sections are bordered in

the south by Toronto's theatre district and in the west by Toronto's fashion district. Sev eral ofthe City's night clubs are directly lo cated above this run, which also includes a busy fire station.

The contract involved the rehabili

tation of approximately 1500 ft. of 12 in. vitrified clay sanitary sewer which was suffering from varying degrees of cracking and localized missing seg ments. The proximity to other utility conduits (hydro, gas, water and tel ephone) rendered open cut operations cost prohibitive and time consuming.

Every phase was painstakingly reviewed and approved by the City staff to ensure the best possible execution of each task. Several weeks of planning and preparation were needed to coordinate efforts involving: Bell Canada, busi ness operators and building owners, Metropolitan Toronto Fire Depart ment, Metro Transportation Branch, Metropolitan Toronto Police, restau rants and night club owners.

Potable water treatment

The physiology of taste and odour problems In drinking water

Discriminatingconsumers demand

more than a pathogen free drink ing water; they expect water that is inoffensive. They usually re gard the presence of a taste or odour in wa ter as offensive. Odours cause the majority of consumer complaints and even though odours are almost always an aesthetic prob lem that is not directly relatable to public health, when the water smells bad it is also believed to be harmful. Taste Salty Bitter Sour Sweet

threshold concentration can vary as much as a million to one between strong and weak odours. Some odours in water have been

described as rotten, grassy, earthy, musty, fishy, spicy, aromatic, medicinal, etc. Most sensations of taste are really smells due to volatile substances vaporizing in the mouth and releasing odour-causing chemical mol ecules which reach the olfactory nerve. The olfactory nerves send impulses to the brain that are interpreted as odour and/or taste. Customer Complaints In water systems, several different conditions give rise to customer odour complaints. The intensity of an odour

Medicinal, etc Odour problems in water are due to volatile organics from decaying fish, algae, mussels, vegitation, and certain inorganics(such as hydrogen sulphide) reaching the nose.

The smell itself or the character ofthe

odour is also an important factor in causing complaints. Some odours will be regarded by consumers as natural in origin and are therefore deemed of less concent than if an odour is viewed

to be unnatural in origin such as syn thetic chemical, petroleum, or medici Figure 1: The characteristics of taste and odour in nal odours. Consequently, the inten sity, the change in intensity and the drinking water. Physiology of Taste and Odour Taste is determined by receptors, or tastebuds, located on the surface and sides ofthe tongue, the roof of the mouth, and the entrance to the pharynx. When substances in solution stimulate the nerve fibres in each

tastebud they transmit impulses directly to the brain. The receptors can only distinguish the four qualities of sweetness, sourness, saltiness, and bitterness. The receptors at the back of the tongue transmit the sensa tion of bitterness. Those at the tip of the tongue transmit sweetness. Saltiness and

character ofthe odour(s)can determine the number ofconsumer complaints and the need for action.

centration of the odour compound. This re lationship is illustrated in Figure 2. The horizontal axis shows the relative concen

tration of odour compounds. The concen tration is plotted on a log scale. The vertical axis shows a 1 to 12 scale starting with the threshold odour intensity and with three broad odour regions ofslight, moderate,and strong. The sensitivity ofindividuals to vari ous odours is very subjective and varies widely in any population. Therefore, meas uring odour intensity accurately is very dif ficult.

Some important attributes of odours can be illustrated with this diagram. For in stance, the same odour compound (Odour A)will produce a greater response at a higher temperature. This suggests consumers will have more problems with warmer tap water and heated water. Also different compounds (Musty Odour A and Musty Odour B) can produce quite different odour intensity re sponses with respect to concentration al though the character of the odour may be the same. This difference signals that the compounds are chemically different and will behave quite differently in response to vari ous treatment methods. Odour Controi and Removai

Some water producers have used water shed management to reduce the number and intensity of odour episodes. Control of nu trients input that can stimulate algae growth, control of watershed development,reservoir level manipulation and the use ofan algicide are tools that have been effectively used. However, many surface water supplies do

To be perceived, a sub stance must be volatile enough to get into the air near the olfactory nerves in the ceil ing of the inner nose. The substance must be at least partly soluble in the mucous cov ering of the olfactory receptors, and a mini mum number of odour causing chemical molecules must be in contact with receptors for a minimum length of time. The human nose can identify a myriad of different odours. As well it can discern very minute quantities although the "just-noticeable"

Odour removal is usually very difficult and very expensive. Consequently,complete odour removal at all times is probably not feasible. In all cases where an odour prob lem occurs at a water treatment plant, the most cost-effective first step is to optimize the existing processes for particulate re moval. By ensuring that the water plant is consistently producing a low turbidity wa ter this ensures that most of the particulate odour is removed. This will leave only the

soluble portion of the odour producing sub stances.

not often justify the costs. For the Zone II, either the percentage ofcustomers that com plain about the odour, or the number ofcom plaint occurrences per year reaches a point where the water supplier will spend capital and operating dollars to set up a specific treatment program for odour removal. Gen erally this will be processes that are not capi tal intensive, can be stopped and started as necessary, and have a wide response range to various odour causing substances. Ex amples of these treatment processes would be oxidation using potassium permanganate, chlorine, chorine dioxide, and adsorption using powdered activated carbon. Aeration can most effectively remove highly volatile substances that cause petroleum, medicinal and rotten egg odours. In Zone III more effective treatment systems would need to be put in place because the intensity and character of the odour result in a high per centage of customer complaints with each occurrence, or a high frequency ofcomplaint occurrences. Aeration, chlorine, chloramines, chlorine dioxide, and potassium per manganate generally may not be effective. The dosage of powdered activated carbon may increase to a point where the increased cost ofthe chemical and cost for treating the resultant sludge no longer makes this proc ess cost effective. These circumstances may warrant more capital dollar intensive solu tions such as oxidation using ozone and ad sorption using beds of granular activated

an important role in establishing the water quality characteristics of combined sewer overflow and of the sewage entering a wastewater treatment plant. In a paper pub lished in Water Science and Technology, Hydromantis scientists B. Gall and ITakacs, and G, Patry of the University of Ottawa, describe a simulation model they developed that shows the effects ofreactions in the col

lection system on wastewater treatment plant

performance. A series of numerical experi ments was conducted to illustrate the fea

tures ofthe model and the potential benefits of the approach.

Biological Dehalogenation of 2-Chlorophenol Seed materials were prepared from anaerobically digested sewage sludge, sedi ment from a bleached kraft(13MK)mill aer ated lagoon, and an anaerobic bioreactor biomass treating BMK wastewater. The ef fectiveness of these to dehalogenate 2chlorophenol was investigated by Univer sity of Manitoba scientists S.K. Basu, J.A. Oleszkiewicz and R. Sparling. As described in a paper accepted for publication in Water Research, dehalogenation was observed in batch tests after extensive lag periods last ing from 97 to 250 days. The dehalogenation

rates with digested sewage sludge were bet ter than those with the lagoon sediment or the bioreactor biomass. Digested sludge, which was adapted to 2-chlorophenol over a one-year period, converted the chlorophenol to phenol immediately.

Removal of Volatile Organic Compounds The fate of selected volatile organic com pounds(VOCs)in anoxic and anaerobic se lectors was investigated by W.J. Parker and H. Monteith, Environmega Limited, and the Wastewater Technology Centre's H. Melcer. Tetrachloroethylene, 1, 4-dichlorobenzene,

and 1, 3, 5-trimethylbenzene were consist ently removed at efficiencies in excess of 30%. The selector biomass concentration

and hydraulic retention time had little ap parent effect on the VOC removal efficiencies. The results of these experi ments, described in Water Environment

Research, demonstrate the potential of se lector technologies for reducing the mass loading of VOCs to aeration basins.

Groundwater Nitrate Profiling A multilayer sampler was used by Univer sity of British Columbia scientists R. Dasika and J. Atwater to passively sample groundwater nitrate in two unconfmed aquifers. Monthly sampling performed over a threemonth period at each location has shown the

feasibility of using this technique over ex

tended depths. As descrihed in a Rapid Com munication published in Water Research,the method can provide a detailed and highly repeatable characterization of the groundwater chemical profiles.

Mathematical Modelling of withln-lake Relationships In a paper published in the Canadian Jour nal ofFisheries and Aquatic Sciences, Uni versity of Quebec scientist Y.T. Prairie and C.T. Marshall from McGill University present a new method to extract empirical relationships from the internal structure of a time-series within a single lake. When ap plied to empirical data for phosphorus and chlorophyll concentrations collected daily over one field season, the estimated struc tural relationship was nearly identical to that estimated from cross-sectional data even

though the empirical trend appeared much shallower and very weak.

Pesticide Leaching In Atlantic Canada

Scientists from Agriculture Canada, Envi ronment Canada and the University of New Brunswick used field-scale tile drainage sys tems, private wells in farming areas, and re

search piezometers installed at field edge to evaluate the nonpoint source impacts offour pesticides on groundwater quality. As de scribed by P. Milbum and coworkers in the Water Quality Research Journal ofCanada,

Because of concerns about the contribution

of agriculture to eutrophication of the Great Lakes by fertilizers, A.J. Gaynor and W.I. Findlay compared phosphorus loss from com production using conventional and two conservation tillage treatments. As described in the Journal ofEnvironmental Quality, the ortho-phosphate concentration in runoff was 1.7 to 2.7 times greater from conservation tillage as compared with conventional till age although the average soil loss was about one-half. Subsurface drainage accounted for 55 to 68% of the phosphate transport. Dis solved phosphorus accounted for 84 to 93% of the phosphate transported from the three tillage treatments. These Agriculture Canada scientists conclude that conservation tillage

effectively reduced soil erosion but increased phosphate loss.

The concentrations ofthe heavy metals zinc, lead, cadmium, chromium, and copper in solid waste Auto Shredder Residue (ASR) have been measured and their leachability evaluated. National Research Council of

Canada scientists M.Day and F.T. Awadalla identified the importance of pH and a buff ering agent as key features in determining the leachability ofthese metals. The results, published in Environmental Technology, in dicate that, when ASR is subjected to stand ardized leaching tests, only small quantities ofheavy metals are solubilized and detected in the leachate. The ASR is also capable of absorbing additional quantities of lead ions from solution.

Wastewater treatment

By Rick Sanderson & Blake Nesbitt'

Demand for process water also helps refine wastewater treatment he

Ontario

Government's

Municipal-Industrial Strategy for Abatement (MISA) emphasized the need for improved wastewater management. But, it has been Ontario industry's never-ceasing demand for process water that has encouraged ongoing efforts to expand and refine wastewater treatment

T

technology. In 1989, Laidlaw Environmental Serv

ices acquired an unfinished wastewater treat ment facility in Guelph, Ontario. Although political and economic forces of the early 1990s seem to have diluted the importance of MISA's municipal discharge targets, gen erators are becoming increasingly aware of the need to improve their wastewater man

agement practices. The trend encouraged the company to use its Guelph site to establish a plant and associated evaluation project, to expand its understanding of, and service expertise in, industrial wastewater treatment technology and problem solving. The following is a case study of how a proven treatment technology was adapted to meet the needs ofindustrial wastewater gen erators.

Project defined In a manner compatible with MISA,the initial intent of the project was to develop a wastewater pretreatment technology capable of managing a wide variety of wastes. As provincial interest in pursuing MISA's municipal component waned, wastewater generator needs and trends were re-evalu ated. As a result, the scope of the project was narrowed to focus on a treatment solu

tion for non-hazardous industrial liquid wastes containing water-soluble organic con taminants.

When completed,the project would yield an operational facility, providing generators of the target wastes with an effective treat

taminated groundwater, used oils, off-spec materials and phosphate rinse waters. Characteristically, volume and composition vary by generator. The challenge for the project team was to develop and demonstrate the best avail able technology to efficiently and cost-ef fectively treat the target industrial wastes to standards compatible with municipal sewer system acceptance parameters.

Suitable technology determined To determine a suitable treatment proc ess, five technologies were evaluated: dis tillation; solvent extraction; membrane technology; biochemical oxidation; and tra ditional physical/chemical treatment. Each technology was considered for its ability to meet predetermined criteria relat ing to: ease of operation (operability); capi tal and operating costs; ability to effectively treat the target wastes; and volume and man ageability of by-products generated. Capital and operating costs had to be sufficiently low to allow the process to per form in a highly competitive marketplace. The waste streams generated from the treat ment system had to be minimal, with residues efficiently handled and disposed of cost effectively. As well, the system had to be capable of effectively treating the target wastes, which would be received in batch loads, each of varying composition. Table 1 provides an overview of the findings. Biochemical oxidation was selected as

the preferred technology, performing within an acceptable range for all parameters. The technology would later confirm its adaptabil ity for single-, or multi-user operations. Biochemical oxidation treatment uses

microorganisms to remove suspended and dissolved organics in wastewater. By creat ing a suitable working environment, the microorganisms consume and convert the organic wastes into gaseous and cell tissue by-products, which can be separated from the water component. The working environ ment for the microorganisms, referred to as

an activated sludge, or biomass, or mixed liquor, is created by introducing a turbulent air flow into the wastewater. Being denser than water, the solid by-products of the proc ess are subsequently separated by gravity set tling. Process challenges defined The use of microorganisms in an oxy genated environment is a proven treatment technology. It has been used for decades in municipal wastewater treatment plants. More recently, the technology has been ex tended to include some industrial applica tions. But, could a technology traditionally used to treat large, consistent waste streams be applied to small batch volumes of varied composition? In responding to the specialized manage ment needs of wastewater generators, the scope of the project ultimately focused on two key challenges: to maintain a consistent in-process environment, which would enable the waste-consuming microorganisms to function efficiently and effectively; and to acclimate the microorganisms to destroy the wide range of industrial contaminants con tained within the target wastes. The treatment system The treatment system constructed con sists of three 45,000-litre tanks, a blower,

an air diffusion system (see Figure 1) and associated pretreatment and bulk storage tanks, as well as feed and decant pumps. To achieve maximum flexibility, the system is operated manually, on a sequential batch basis. The design capacity for the pilot project was 10,000 litres per day, although throughput varies depending on the strength of the wastewater being processed. At the facility, waste is processed as nonoily, or oily wastewater. Oily wastes are gravity settled in the oily water process tank. The emulsified oil is acidified to a pH of less than 2.0 using sulphuric acid. The batch is then heated to 80 degrees Celsius, to sepa rate the oil and water. The aqueous layer is neutralized with caustic and pumped to a

ment solution. In the process, an indepth working knowledge ofthe wastewater prob lem-solving process would be gained â&#x20AC;&#x201D; an important asset considering the dynamics of this segment of waste management.

Wastewater treatment, cont'd. cone-bottom settling tank. The upper layer oil phase is transferred to an oil storage tank, to be shipped offsite for recovery and re-use. Non-oily wastewater is received into cone-bottom settling tanks. Coarse sus pended solids gravity settle to the bottom of the tank to form a sludge. The sludge is pumped through an enclosed screw auger to one of two batch mixers. After undergoing solidification, the fixed sludge is transferred to luggers and disposed of off site in a sani tary landfill. The aqueous phase is pumped to the prefiltration tank. After passing through a basket filter, the water is pumped to filter press conditioning tanks and inor ganic contaminants are precipitated from

is transferred in batches to the biochemical

treatment process tank. The biochemical oxidation process is aerobic, conducted in a sludge medium. A balanced system is maintained primarily through the control ofthe Biochemical Oxy gen Demand (BOD) levels. Other operat ing control parameters include: temperature, microorganism population density, the foodto-biomass (F/M) ratio, hydraulic retention time (FIRT), sludge age, and the BOD-tonitrogen-to-phosphorous (B/N/P) ratio. The treated water is separated from the sludge by gravity settling and decanted to a filtrate tank. When the filtrate tank fills to

capacity, the effluent is analyzed to ensure compliance with local municipal standards before being discharged to the sewer. Adapting the technology

In adapting the technology for the project, the target waste streams were defined in

terms of their discharge-to-sewer quality. The criteria were based on the MISA model

sewer guidelines, which list water quality pa rameters for a myriad ofcontaminants. BOD was identified as the only parameter that could not be complied with using conven tional sewage treatment system methods. BOD, measured in parts per million (ppm), defines the amount ofoxygen neces sary to break down specific contaminants in wastewater. When organic contaminants are present in a waste stream which is released into a watercourse, natural organisms living in the water will attempt to break down the carbon chain structure of the waste. In the

process,the microorganisms consume oxygen. The oxygen required to complete the re action, measured as the BOD, is acquired from the residual oxygen present in the wa tercourse. As a critical element of the bio

chemical process, the supply ofoxygen must be maintained.

Most industrial waste streams containing any organic component will exert a BOD

BOD (mg/L) (x 1000)

when released directly to the environment. Municipal wastewater treatment facilities are designed to remove BOD found in typical sewer effluent, so long as levels do not ex ceed the systems' treatment capabilities. However,excessive BOD loading can upset

the conventional biochemical treatment sys tem, resulting in incomplete treatment. The plant would evaluate the pretreatment of wastewaters containing high-end BOD. initially in the range of 500 ppm to 10,000 ppm. With such wide-ranging BOD levels to contend with on a daily basis, an efficient method of calculating and monitoring oxy gen levels in the biochemical treatment proc ess tank became a necessity to ensure the system's effective operation. BOD data was also required for the establishment of other operating parameters, such as HRT, which is the amount of time the waste must spend in the process tank, and sludge age, measur ing the remaining lifespan of the activated sludge. Unfortunately, a standard BOD labora tory analysis could not be used to evaluate daily incoming wastes, since it takes five days to complete. The project team needed relatively accurate BOD data in a matter of minutes, not days. Respirometric techniques were consid

Environmental Science & Engineering, January 1996

ered as a quick, economical alternative to the standard BOD test. In respirometry, a known volume of activated sludge is stirred in a sealed bottle, which is maintained at a

constant temperature. The dissolved oxy gen content(D.O.)ofthe slurry is measured at one-minute intervals for a test period of up to 15 minutes. A graph of D.O. concentration-versuselapsed time is prepared, with the slope of the best-fit straight line determined. The slope ofthe line is the Oxygen Uptake Rate, or O.U.R., expressed in milligrams of oxy gen per minute(mg 0,/m). Ifthe suspended

solids concentration of the activated sludge is known, the data can be normalized and expressed as the Specific Oxygen Uptake Rate, or S.O.U.R.

To estimate the strength ofcontaminants in a target waste, the S.O.U.R. test is re peated. For the process, however, a small quantity of the activated sludge is replaced with a known volume ofthe target waste. If the waste contains appreciable bio-degradable organic contaminants, the rate of oxy gen consumption will increase. As a result, the slope of the D.O. concentration-versus-time line will be steeper. The relative change in the S.O.U.R. value can be directly correlated with the waste's strength, or its BOD value.

As no concrete BOD data existed during the very early stages of the pilot project, op erating parameters were based on assump tions developed from preliminary informa tion gathered from bench-scale tests con ducted during the project's design phase. To avoid system upset caused by a con taminant in marketplace wastewaters which had not been accounted for during the benchscale tests, a conservative approach to waste addition was maintained throughout the acclimation period. Over a 60-day period, operating parameters for microorganism concentration and effluent quality were es tablished.

Buyer should beware of contaminated land

Arecent Ontario Court decision

concerning the purchase of con taminated land has upheld the age old principle that "Buyer Beware". In the case of Tony^ Broadloom and Floor Covering Ltd. v. NCM Canada Inc. (1995), 22 O.R.(3d) 244 (Gen. Div.), the purchaser of a property used for metal stamping found that he could not escape his purchase agreement after discovering that the site suffered from serious varsol contamina

tion ofthe soil and groundwater. The Court held, among other things, that the contami nation ought to have been discovered by the purchaser prior to entering into the agree ment, that the purchaser had failed to exer cise reasonable diligence to satisfy itself of the condition ofthe real estate and therefore,

was bound by its agreement. The facts of the case are relatively typi cal for a contaminated industrial site. The

vendor operated a metal stamping factory on the property, using a series of metal presses and oils. Varsol was used to clean the ma

chinery. Between 1979 and 1985 the ven dor disposed of approximately 20 litres per day of dirty varsol by pouring it onto the ground at the rear of the factory. This re sulted in contamination of the soil and

groundwater. The dumping ceased in 1985, possibly because in that year varsol was clas sified as a hazardous waste by the Ontario Ministry of Environment. In the same year the vendor sought the expert help of Monenco Consultants Ltd., environmental

engineers, to investigate the situation. In accordance with Monenco's advice,the ven

to closing the sale transaction, Monenco delivered its final report to the vendor, out lining the further steps that would be neces sary to control the varsol contamination. The vendor did not reveal this information to the

purchaser and the transaction closed as

property being appropriate for residential use. Furthermore,there was no evidence that

the vendor had actively concealed the con dition, which is generally required to rescind a sale of land contract, unless the defect is sufficiently serious to make the land unus

the purchaser had been provided ample op portunity to inspect the property, but failed to do so. The offer to purchase recited that the "purchaser acknowledges having in spected the property prior to submitting this offer". Prior to closing, a planning consult ant recommended to the purchaser that he contact the Ministry of the Environment. The purchaser neither followed the recom mendation, nor did it retain any consultant to carry out investigations of the property, notwithstanding its alleged intent to develop the property as a residential condominium.

The evidence of the vendor, which was ac

cepted by the Court, was that the monitor ing wells and pipes on the property were reasonably visible and ifseen, ought to have caused the purchaser to make further enquir-

ity. In this case the Court was satisfied that of the property, but only restricted its high est and best use, did not meet the test. Ac

cordingly,there was no obligation on the part of the vendor to disclose the information it

possessed concerning the varsol contamina tion.

Tony's Broadloom sends a strong message to buyers of land that they cannot assume that vendors have an obligation to disclose adverse environmental conditions of their

real estate. This is particularly the case where sophisticated parties and the more common forms of contamination, such as petroleum contamination are involved. The common

commercial practice of carrying out Phase I and Phase II environmental site assessments

sets a standard of diligence which no pur chaser can afford to ignore. This is particu larly important given the complex array of development restrictions which flow from a land's failure to meet government clean-up guidelines, not to mention the difficulties one may experience in financing or reselling the property. An appeal ofthe case is pending.

dor initiated a number of measures to con

trol the varsol contamination, including in stalling a containment well. Some time in 1987 the purchaser, Tony's Broadloom and Floor Covering Ltd., which was located down the street from the sub

ject property, learned that it was for sale. The President of the purchaser approached the vendors and they ultimately entered into an agreement of purchase and sale on January 8, 1988. At the same time the vendor had received another offer which was not pur sued because, according to the vendor, the offer was conditional upon the results ofsoil testing and approval to change the zoning from industrial to residential. The offer of

Tony's Broadloom contained no such con ditions.

The sale was scheduled to be completed

on September 6, 1988. In the meantime, Monenco advised the vendor that the varsol

contamination situation was getting worse and the pumping system was not operating as it should. In August 31, 1988,just prior

ies or investigations.

The Court held that at law,for a purchaser to rescind an agreement for the sale of land, it must demonstrate that any defect in the condition of the property was latent, i.e. undiscoverable through reasonable inspec tions. In the words of the Court, the rule of Caveat Emptor or Buyer Beware requires that a purchaser take that which it sees, or which, as a prudent and diligent purchaser, it ought to have seen. In this case the Court found that the varsol defect was not latent, but discoverable by the purchaser. The pur chaser's president was an experienced busi nessman who had the advantage of operat ing his business down the street from the subject property. It was the purchaser's choice not to inspect the property and if it intended to use the property for residential purposes, the onus was on the purchaser to ensure that the property could be so used. Tony's Broadloom should, said the Court, have carried out a proper inspection, asked pertinent questions ofthe vendor and insisted on making the purchase conditional on the

The Caswan Thermal Distillation proc ess should be viewed as consisting of five subsystems; the low temperature dryer, the low temperature scrubber, the high tempera ture processor, the high temperature scrub ber and finally, the chiller. These compo nents are shown in the diagram. The solids within the low temperature dryer are heated to 500°F by hot oil pumped through a hollow screw mixing auger. Heat ing of the solids is conducted under a nitro gen blanket. The gases generated from this process(primarily water vapor)are directed to the low temperature scrubber. The intent ofthe low temperature dryer operation is to dehydrate the solids and avoid excessive energy consumption in the high temperature processor.

The dried solids are then directed to the

high temperature processor where heat is transferred through the alloy steel rotary kiln tube by combusting natural gas in a firebox surrounding the kiln. Residence time ofthe solids within the tube is controlled prima rily by the rotary kiln speed, and to a lesser extent the slope of the kiln. Heating of the

solids is conducted under a nitrogen blan ket. The gases evolved from heating the solids are directed to the high temperature scrubber.

Trays are installed in the low tempera ture scrubber similar to the high tempera ture unit, again, to provide intimate gas/liq uid contact. This scrubber receives the offgas from both the low temperature dryer (pri marily water vapor) and the high tempera ture unit, and condenses most of the gase ous components by cooling the stream to 90°R The remainder of the gas phase com ponents (residual water vapor and nitrogen) are directed to the chiller.

The chiller further cools the gas stream (42°F) to remove remaining water vapor. Noncondensible gases are directed through a water knock out system prior to combus tion in the high temperature processor heat ing burners. Mass Balance

The system was operated at a nominal feed rate of 20,950 Ibs./hour, with a mois ture content of 12.48% determined by oven drying at 220°F. The average hydrocarbon ofthe methylene chloride extracted crude oil

was recorded as C^j. The mass flow rate of inert solids through the system decreased by 1% due to particulate carryover from the thermal processing vessels to the scrubbers. The amount of sludge recovered from the scrubbers has in the past been demonstrated to average approximately 0.03 tons per ton of feedstock.

Discussion

Wide variation in the feedstock hydro carbon levels is presented by utilization of various extraction and analytical methods. This variation is likely due to the complex chemistry of the crude oil to be extracted and to the extraction solvent of choice. It is

thought that the polarity of the solvent and the solute impacts the extraction efficiency. The polarity of a molecule is a measure ofthe distribution of charge across the mol ecule. A charge that is evenly distributed across a molecule such as in most alkanes

effectively makes the molecule nonpolar. A charge that is separated across a molecule creates a polar molecule such as water. It

should also be recognized that the terms polar and nonpolar represent extremes, and that molecules can possess degrees of polar ity within the two extremes. Under ideal

circumstances, the solubility of one sub stance in another is a matter of matching solvent and solute polarities. In addition to polarity considerations, it is thought that as hydrocarbon molecules increase in size, the intermolecular attractive forces also increase

Error in the mass balance is likely attributable to the estimated volume ofsludge produced and the difficulties ofob taining a representative sludge sample. Despite the difficulties in closing the car bon mass balance, it is believed that several conclusions can be drawn.

C, so that polarity matched solvents may also require energy to overcome these inteimolecular forces. In these instances, energy in the form of heat must be added to the sys tem to drive the solvent reaction, resulting

in the extraction of higher molecular weight hydrocarbons with the undesirable aspect of loss of lower boiling point hydrocarbons through volatilization. The methylene chloride, toluene, and freon extraction analyses displayed decreas ing levels of hydrocarbons. The methylene chloride solvent is thought to be slightly po lar, whereas toluene and ffeon to be nonpolar. It is thought that the crude oil contaminant possesses some slightly polar components, thereby explaining slightly better extraction with methylene chloride. On the other hand, it is thought that freon displayed the poorest extraction due to its nonpolar nature,and low energy levels.

Im provement to the thermal processing vessel's seals are suggested to minimize the ingress of leakage air beyond that afforded by the current design.

ing paraffins, isoparaffms, aromatics, napthenes and asphaltenes suggest that there is likely no single solvent suitable for extract ing all of the petroleum hydrocarbons. The total organic carbon(TOO)analysis of the solids subsequent to oven drying and methylene chloride extraction was recorded at 2.3%, indicating significant levels of nonextractable organic compounds were present in the soil feedstock. It is thought that this analysis indicates the level ofhumic or cellulose matter in the soil and high mo lecular weight petroleum hydrocarbons. The total mass flow input of carbon to the system (according to TOG analysis, prior to extraction), was recorded at 530 Ibs./hour. Total mass flow of carbon exiting the sys

carbons suggest that a significant level of "cracking" or decomposition is occurring in the high temperature process. The cracking of the high molecular weight hydrocarbons should result in higher carbon to hydrogen ratios in residual treated soil hydrocarbons. It is believed that the thermal desorption process removes high molecular weight hydro carbons by a series of processes or reactions: • simple phase change or volatilization; • decomposition to produce free hydrogen or hydrocarbon compounds with low carbon to hydrogen ratios; • partial oxidation, which can be mitigated by minimization of leakage air. In conclusion, although the high molecu lar weight hydrocarbon compounds are dif ficult to remove from soil due to their boil

ing points, it has been shown that removal of these contaminants is achievable through a combination of reactions and processes.

This preparation included pressure washing the surfaces to remove any deleterious materials such as form oil and dust to obtain a smooth surface. Once the surface was inspected and approved by the manufacturer of the coating material, a certified applicator coated the exterior ofthe maintenance hole sections. Finally, safety landings, ladder rungs, and aluminum hatches were installed to complete the maintenance holes. Precast concrete maintenance holes are integral components to the leachate collection system of the Halton Waste Management Site. The engineered structures are specially designed to resist the possible attack by sulphate and a chemical cocktail found in landfill leachate. The system must continue functioning for decades after the cell has been closed.

The Halton Waste Management Site has approval for the dis posal of 7.96 million m'of solid waste over the next 20-30 years. Daily intake is expected to range from 500-800 tonnes per day. The start up cost of the project is S52 million. For more information, Circle reply card No. 187 Enviromnental Science & Engineering, Januaiy 1996

Mechanical aeration reduces need for

additional land in Alberta lagoon facility reatment of domestic sewage through the use of stabilization lagoons is a common practice for many small to medium sized communities. When these systems become overloaded, the prospect of resolving this problem by merely expanding the existing system is not necessar ily feasible or cost-effective. When the community of Valleyview, Alberta was faced with this problem, it elected to convert the existing stabilization pond system to a mechanically aerated treatment facility. In so doing the community eliminated the need to acquire additional land area and deferred major capi

Financing Water & Wastewater Services

By Sherry Eaton*

An assessment of current practices and the need for change

Theavailability ofclean water and

the proper treatment of sewage are important to all aspects of economic activity and public

health. Yet, when one thinks ofinfrastmcture

renewal, the most obvious examples of the areas of need are roads, bridges, hospitals and schools. Our buried services, primarily water and wastewater systems, are often ignored because of their low visibility. It is estimated that capital spending on water and wastewater infrastructure by Ontario's municipalities is approximately $750 million per year. This value falls sig nificantly below the MOEE's Needs Study estimate of$19 billion over a 15 year period or $1.3 billion per year required for the re

frastructure, as well as significant expendi tures associated with the related daily op eration, maintenance and administration. Typically, municipalities receive revenues for the financing of their water and wastewater systems from a variety ofsources including

This discrepancy results from the lack ofspending and the need to address several key issues including: the inability of many water and wastewater plants to meet current quality criteria; numerous plants are close to or exceeding their design capacity; water and effluent guidelines are becoming

increasingly stringent; and existing water and wastewater systems have been poorly main tained for years. The primary reason for the significant lack of spending on our water and wastewater systems is the lack of available and adequate funding. This report will therefore review the current methods of financing water and wastewater systems in Ontario and examine the problems associated with these financing methods. The need for change will

be summarized and recommendations for the

improvement of existing financing systems will be presented. Suggestions on how to implement some of these recommendations will also be provided. Typically in Ontario, water and wastewater services are supplied entirely by mu nicipal or provincial governments. In larger communities, water services may be provided by a public utility commission appointed by the local government to operate the water sys tem on behalf ofthe community. Water and wastewater systems are sup ported by an extensive network ofinfrastruc ture, including that required for the treatment, storage and distribution of water for domes tic and industrial purposes, as well as that required for the collection, conveyance and treatment of wastewater. Figure 1 provides an overview of the basic systems and serv ices provided by a municipal water and wastewater system.

Figure 2 Typical Rate Schedules Used In the Billing of Water and Wastewater Services of charges is commonly referred to as the water rate and includes charges for water and, in some cases, wastewater services. When setting a water rate, a municipality must con sider both the price structure (the method of charging for water and wastewater service based on the quantity used) and the price level (the actual price charged for a given volume of water). A variety of different rate schedules exist. The four major types ofrate schedules are described below and depicted in Figure 2.

ist: declining block rates and increasing block rates. Declining block rates charge a successively lower price for set volumes of water as consumption increases through a series of "blocks". Essentially, the bill to the consumer climbs slower at the higher vol umes of water used. Declining block rates provide a decreasing incentive to conserva tion because the marginal cost declines as water use increases. Approximately 36% of Ontario's serviced population is charged us ing a declining block rate structure. Increas

ale used when setting declining block rate and flat rate pricing systems. However, upon a closer look, many situations designed to be equitable are in fact inequitable. For ex ample, large industrial water consumers are often charged based on a declining block rate structure (costs decrease with increasing use), however, in many cases it may be that the largest users dictate the system design capacity which is one of the most important and costly design parameters for water and

The ideal financial system Municipal water/wastewater rate making should meet three basic goals: economic ef ficiency, equity and full cost recovery. Economic Efficiency. Economic efficiency is a term that refers to achieving given ends at the lowest cost possible. In the water and wastewater servicing field, efficiency occurs when the price of providing the water and wastewater service equals the cost incurred in supplying the next additional user. In other words, price should equal marginal cost. Under such conditions, service occurs at minimum cost, customers are treated equally, system repair and upgrading costs are ad equately covered and system expansions oc cur only when required by demand condi tions. Additionally, since the customer is adequately informed about the true costs of water services, water demands occur effi

ciently at the least cost to society. Equity. Equity is concerned with sharing the costs of water systems amongst custom ers in a so-called "fair" manner. This con-

cept, while appearing simple and beneficial is difficult to define in practice and is open to wide misinterpretation amongst rate set ters. The fixed portion of a municipality's total costs (eg., administrative, billing and maintenance costs) are incurred regardless of volume of water used by individual cus tomers or customer classes. Accordingly, these system-wide costs should be bome by

wastewater systems.

Full Cost Recovery. A pricing system achieves full cost recovery when it gener ates sufficient revenue to cover the full cost

of the system at any level of water delivery. The accounting system costs should include fixed costs, variable costs, costs of depre ciation, and provision for future expansion. If these costs are not fully recovered, mu nicipalities will continue to require subsidies from senior levels of government or trans fers from other internal budgets in order to maintain, upgrade, or expand their water and wastewater systems.

Current practices In general, current water and wastewater rate schedules utilized by Ontario's munici palities fail to meet the three basic goals of economic efficiency, equity and full cost re covery associated with water and wastewater financing. Failure to recover the full cost of

In Ontario, the development and setting of water rates is established by individual municipalities. Many municipalities have several rate schedules. For example, a sur vey of water pricing practices carried out by Environment Canada in 1987, indicated that

over 1,100 separate rate schedules were cur rently in use by the 470 municipalities re sponding to the survey. Additionally, many of the rates currently in use are set by mu nicipal councils. Municipal councils tend to be biased due to their political agendas, are in competition with other municipalities (especially in attracting industry and new de velopment), and poorly understand the eco nomics involved in establishing efficient and equitable rates. Lack of incentives to conserve

Many of the rate schedules used in On tario provide no incentive to conserve wa ter. Currently in Ontario, 33% of the serv iced population is charged using a flat rate method of water pricing. Flat rate water pric ing promotes excessive water use because the price of each additional unit of water con sumed is zero and therefore there is no in

centive to reduce consumption. Another, 34% of the serviced population is charged for their water and wastewater services based

type implemented appears to be a significant factor in determining the volume of water

used per person. As shown in Figure 4, the per capita residential water use is highest under a flat rate system. Lack of use of water meters

A key factor in assigning costs fairly to customers and in providing the incentive for water conservation is metering. By know ing the amount of water consumed,custom ers can self-monitor their water consump tion and, because their water bill is directly related to consumption, there

Recommendations and

Implementation A municipality can eliminate many ofthe problems associated with the financing of water and wastewater systems, as discussed above, by ensuring adequate funds are avail able. This can best be achieved through the pricing of water and wastewater services at their flill cost and devoting revenues to wa ter and wastewater systems only. Implement full cost pricing

The program must

be supported with equal effort by the mu nicipality itself through the installation and provision of water efficient fixtures and pro grams.

of the full cost a municipality must bear to supply water and wastewater services. In many cases, water and wastewater

proximately $60,000 per year, water and wastewater customers should be paying up wards of$600 per year. Current household water and wastewater expenditures in On tario are however, in the order of $200 per year. Lack of dedication of revenues

Traditional municipal accounting prac

tices often do not provide the necessary data on costs and revenues associated with water

and wastewater systems and most often lump

any received revenues into a general fund or public works account rather than a separate water and wastewater system account. As a

result, many municipalities are not aware of the true costs associated with their water and

wastewater systems and are unable to deter mine the degree to which existing revenues cover costs. Effective budgeting and finan cial planning are hindered under such a sys tem.

The setting of water rates in Ontario is not regulated by government nor are there presently any generally adopted procedures for their development. Municipalities should rely on the experience and practice of suc cessful municipalities in Ontario, assistance from provincial and federal levels of gov ernment and rate setting guidelines devel oped by agencies such as the American

The people and businesses of Ontario can be best served by water and wastewater sys tems that are well managed, self-sustaining enterprises. In order to do this, we must be gin to regard both water and wastewater sys tems as one stand alone, self-financing en tity. By setting rates based on the full cost of service and devoting water revenues to water utility expenses only municipalities can ensure adequate financing, encourage con servation, and increase public awareness concerning the true value of water resources. As long as funding is available from up per levels ofgovernment, municipalities will never seriously consider implementing full cost pricing. As a result, the federal and pro vincial governments must take the first step by making it clear all funding is on a short term basis only and that all municipalities should be moving rapidly towards self-suf ficient, equitable and efficient water and
