I

am truly honored and feel so blessed to be Chair this year. I’m sure several of you were just as disappointed as I was to miss out on the Texas Water 2020TM Conference in Fort Worth this past April. I personally look forward to Texas Water every year and the ability to network and collaborate with like-minded professionals. As I transition into the role virtually, I am excited about coordinating with MELISSA BRYANT the multiple divisions and committees and 210-302-3611 setting new goals for the year. mbryant@sara-tx.org In these unprecedented times of COVID-19, I hope everyone is healthy, safe, and looking forward to the Texas Water 2020TM Virtual Conference. I would like to thank the Fort Worth Planning Committee, especially the conference cochairs, Mary Gugliuzza and Mark Perkins; they had an amazing conference planned for Fort Worth. I also want to thank the GCP Association Services and our Executive Director, Mike Howe, who have been working diligently with WEAT, TCEQ, the presenters, exhibitors and sponsors to ensure our virtual conference is just as successful.

With COVID-19, several of us have been impacted by the multiple closures, sheltering in and having to become technologically savvy to work from home. I’m sure we’ve all become experts on running virtual meetings, teaching schoolwork and throwing virtual celebrations or coordinating drive by parades to celebrate those special occasions. I think it is important to thank all our water and wastewater operators who stepped up and have been working in shifts to ensure our facilities are running during this pandemic. It’s wonderful to know we have safe, clean and reliable water not only to drink, but to wash our hands thoroughly with to stop the spreading of the coronavirus (20 seconds with plenty of soap per the CDC). Several of our wastewater treatment facilities were overwhelmed with everyone staying home and not having toilet paper, so it is great to have operators that can adjust quickly to ensure our wastewater is being treated.

Reimagining Texas Water

BY MIKE HOWE tawwa executive director

W

ell, this is weird.

In the last issue of TEXASh2o, which was just before Texas Water™ 2020 was postponed, and then became Texas Water™ 2020 – Virtual, I was "wandering" through a story about "The Abilene Paradox," a management essay by Jerry Harvey about understanding how decisions are made. I first came across Harvey’s work when I was a student at the UT School of Business and followed his works after I graduated.

The essence of this particular work is simply, as I wrote in the last issue, " . . when we, or organizations, blunder into the "Abilene Paradox" we are taking actions that contradict the very purposes of what we are trying to achieve. It’s not our ability to manage disagreement, but our inability to manage agreement that leads to problems."

The purpose of my article was to discuss the process of decision making that has allowed the Texas Water Conference to continue so successfully for 25 years.

The concluding essence of that article was to explain that I look at the conference as attempting to meet the needs of three prime audiences: the attendees, the presenters, and the collective group of exhibitors, advertisers and sponsors.

For many reasons, each has different wants and needs from the conference, yet their goals are the same—to be a part of the success of such a large conference event that brings the key water professionals together each year to provide successful opportunities for all. Even though the conference is presented by TAWWA and WEAT and an amazing group of volunteers on the planning committee, in my thinking, the three prime audiences are "partners" in making the entire event a success.

| 6 | SUMMER 2020 TEXASh2o

And then, my thinking got tested—big time.

I don’t have enough space to go through the details of how we first postponed the conference and then realized our only option was to go virtual. There were some very hectic moments while MIKE HOWE some were calling for 512-238-9292 mikehowe@tawwa.org immediate postponement or cancellation, and we realized the smart move for all of our audiences was to develop a solid set of answers, and a reasonably complete Question/Answer sheet to post to our website.

There were a lot of questions we just didn’t have answers for, but we knew we had a strong enough relationship with our "partners" to be frank and upfront, to let them know what we knew, and what we didn’t. With a promise to provide more information as soon as we could. After working through various contract issues, we were on track to move the onsite conference to July.

And then we understood that we were not going to be able to host 5,000 people in July or anytime soon.

We knew we had to go virtual.

From that point on, we were forced to throw out everything we knew, that we had planned for, and developed for the 25th Texas Water Conference, and find out the most effective method to present the conference and meet the needs of our "partners" as best we could—virtually.

There was a truly short discussion about cancelling the conference, but that came and went quickly.

Water Quality Based Features and Operational Considerations for Pump Stations Design

BY SUNIL KOMMINENI, JUSTIN BARTLETT & ROOPA METLA, KIT PROFESSIONALS, INC. texas section awwa's water science & research division

P

otable water leaving surface water treatment plants have gone through several steps of treatment and disinfection and is of high quality.

As the treated surface water travels through the transmission pipelines, storage facilities and distribution system pipelines, the water quality will degrade. The conceptual schematic shown Figure 1 depicts the degradation of water quality that can occur with increasing water age. The lower, dashed line shows that if no operational measures are implemented, water quality will degrade significantly as the water

moves through the distribution system. However, by taking measures to reduce water age and/or provide additional stabilization at the regional pump stations, water quality can be maintained through the distribution system, and the benefits of the high-quality water can be delivered to the customers.

EPWater Reminds Customers to "Trust Your Tap"

BY CHRISTINA MONTOYA-HALTER communications & marketing manager, el paso water

A

s concern began in mid-March about Coronavirus (COVID-19), El Paso Water started to see many comments on social media implying that El Paso Water is unsafe to drink, and encouraging people to stockpile bottled water or purchase a filter.

EPWater deployed a multi-faceted outreach campaign that reminds El Pasoans our water is clean and safe to drink, and that they can continue to trust and rely on our services. The campaign consisted of video and radio PSAs, media interviews, social media posts and video interviews with third-party experts.

"At the end of the day, we drink the water and so do our families."

EPWater invests money in state-of-the-art equipment and facilities, tests water continuously through all phases of treatment and distribution to the customer, and ensures employees receive training in the leading water quality practices and technologies.

The 27,000-square-foot International Water Quality Laboratory is a national model for water quality labs.

Lab employees review more than 45,000 samples from treatment plants and throughout the distribution system and perform more than 370,000 tests each year.

"We often talk about our leadership in water supply innovations, but just as essential—if not more so—is

the work we do to guarantee the health and safety of our water supply," President and CEO John Balliew said. "When people tour this facility and see first-hand this modern laboratory, it builds tremendous confidence in what we do."

The utility’s water treatment facilities follow the same high standards in their on-site laboratories.

"If the water entering the plant for treatment changes, these on-site tests will identify it and prompt plant personnel to customize their treatment approach," said Frank Regalado said, Water Plant Assistant Superintendent.

From start to finish and throughout the process, El Pasoans can be confident that professionals are on the job 24/7 to deliver only the best.

"I know how important it is to rest assured that my children are getting high quality water, and I want the community to know that also," said Wilcox.

For warm weather places, a hydraulic residence time of ½-1 day is recommended. The constant flow of water into and out of the GST will assist in preventing thermal stratification and associated degradation of water quality.

Figure 1: Schematic Illustrating Water Quality Degradation in Distribution System

Volume turnover could be optimized by operational changes such as lowering the water level set-points during low demand seasons and increasing the drawdown in each fill/drain cycle. In a well-mixed storage tank, the theoretical water age is equivalent to the average hydraulic resident time. However, actual water age could be longer, if water inside GST is not well-mixed. Poor mixing can lead to pockets of "stagnant zones" with high water ages.

Storage Tank Mixing Strategies Tank mixing can be achieved through either active or passive mixing. Passive mixing involves redirecting water flow to disrupt

| 24 | SUMMER 2020 TEXASh2o www.tawwa.org

| pump | swiftstations program| |

the water in such a way that thermal stratification as well as nitrification are less likely to occur. Active mixing requires the use of pumps and/or some kind of electrical equipment to power a mixing system that operates inside the tank and is independent of the tank inlet in order to achieve a constant flow with no degradation of water quality. a. Passive Mixing Passive mixing strategies rely on the momentum of the incoming water and mixing occurs during the tank fill cycles. Passive mixing is accomplished by fluid disturbance from turbulent jets of the incoming water into the tank. When water flows through an intake pipe into a tank, the incoming water is typically mixed with stored water during the fill cycle by the momentum of the turbulent jet. Therefore, piping configuration plays an important role for passive mixing systems. Key parameters governing passive mixing include incoming water flow rate, GST diameter, GST side water depth, inlet pipe (or orifice) size, number of pipes, and locations of inlet and outlet pipes.

Advantages of passive mixing systems is that it requires low maintenance and is very effective if designed properly. However, the key disadvantage is that mixing occurs mainly during a fill cycle. For regional pump stations that are constantly pumping, passive mixing can be very effective if designed properly. b. Active Mixing Active mixing strategies involve the use of mechanical components such as mixers and recirculation pumps. Active mixing systems can be used to inject disinfectant chemicals directly into the water. Active mixing systems require additional energy (electric, solar, or other) to power the mixer. Active mixing systems can be activated as needed seasonally or during the day.

There are several active mixing techniques which offer varying benefits for each method.

Impeller Mixers

An impeller mixer creates turbulent flow to circulate water in the tank. The face of the rotating impeller blade generates significant fluid motion, both axially and radially. A mixer of this design does not require any pumps, only an external power source.

Submersible Electric Mixer

In this mixer, the water enters through the end-plates and exits through the slots on the top.

The water jets leave the mixer as a sheet of water and create mixing within the GST. The mixer needs external electric power and can be operated on a continuous basis.

Air Mixer

An air mixer uses a system of shooting pressurized air through outlets in order to circulate the water. The air mixing method intermittently introduces filtered compressed air up from a network of outlets and diffusers. An air mixer requires power, filters, and a compressor, but does not require any in-tank electrical wires.

Recirculation Pump Mixing System

A recirculation pump mixing system draws water from the discharge side of the pumps and introduces it back into the tank at the top or bottom. The recirculation water mixes the stored water with its momentum. In this system, all the maintenance equipment is outside the tank and accessible to operations staff.

Water Quality Monitoring and Control Philosophy TCEQ requires monitoring of free ammonia, monochloramine, total chlorine, nitrite and nitrate at entry-point locations, such as regional pump stations and regional water plants. Figure 2 shows an example of a water quality monitoring and control strategy for pump

stations. The primary operating strategy for water quality monitoring and control is to monitor the incoming, stored, and outgoing water quality and provide the operators with the flexibility to inject chemicals to adjust the incoming and outgoing water quality.

Monitoring of the incoming water quality is

| pump stations |

accomplished with online analyzers and daily grab samples. Monitoring of the incoming flow should include parameters such as pH, temperature, oxidationreduction potential (ORP), total chlorine, monochloramine and free ammonia.

Based on the monitoring results, chlorine and ammonia could be added to adjust the incoming water quality to meet the water quality goals identified for the individual regional pump station or regional water plant. For example, chlorine addition should be based on incoming water flow rate, free ammonia and total chlorine

concentrations. In addition to trimming chlorine, a corrosion inhibitor or pH adjustment chemical like sodium hydroxide can be added to the discharge pipeline to further stabilize the water quality. Determination of the appropriate water stabilization chemical has to be made on an individual pump station basis.

To receive free, confidential help from environmental professionals as part of the EnviroMentor program, you must: • Be a small business with 100 or fewer employees, or  a county with less than 100,000 population, or  a city with less than 50,000 population, or  a school district with less than 100,000 students.

• Be committed to complying with state rules to protect the environment, and to correcting violations as soon as possible.

• Be unable to afford the cost of hiring a consultant.

Those seeking help must contact a SBLGA specialist in their TCEQ region. A specialist will provide them with the necessary paperwork and get them started. Then, the EnviroMentor coordinator will review the information and match them with an EnviroMentor whose expertise matches your needs.

The Matching Process The EnviroMentor coordinator sends out a match request with location information, request details, and any deadlines and required certifications. Interested EnviroMentors are then put in touch with the requesting party. In emergency situations, the coordinator may reach out to specific EnviroMentors already known to be capable of meeting the request needs.

A 2019 Success Story On June 12, 2019 around 1 pm, TCEQ dispatched an urgent request for EnviroMentor assistance. A public water system (PWS) had been abandoned by their contract operator and help was requested to ensure public health and safety.

that could take free chlorine and system pressure readings and bacteriological samples to comply with federal and state Safe Drinking Water Act regulations.

The minimum required free chlorine disinfectant level is 0.2 mg/L, the minimum required system pressure under normal conditions is 35 psi, and the Maximum Contaminant Level Goal (MCLG) for E. coli is zero. A site inspection and determination of the amount of remaining PWS disinfectant (free chlorine) was also required.

Hunter Adams and Mark Southard from the City of Wichita Falls responded to the call. Upon arrival they met with several homeowners to hear their concerns and assure them that TCEQ was monitoring the situation. Homeowners then allowed system pressure and free chlorine residual sampling (Photo 1).

Fortunately, all samples were found to be in compliance, demonstrating public health protection, and results were forwarded to the EnviroMentor Coordinator.

A PWS facility site inspection was also conducted.

Several security issues were noted and reported to TCEQ, including a section of cut fencing (Photo 2) and a broken chemical room door lock. Disinfectant levels were checked and it was determined adequate disinfectant was available on site to meet system demands until it could be resupplied the following week.

All sampling and facility inspection requirements were accomplished throughout the afternoon, and TCEQ was notified of the findings within four hours.

Summary TCEQ’s implementation of the EnviroMentor program successfully protects the public by matching systems, small businesses, and independent school districts in need with qualified volunteers that help ensure compliance and public health protection. If you have questions,

please contact Hunter Adams (hunter.adams@wichitafallstx.gov) or Mark Southard (mark.southard@ wichitafallstx.gov).

That effort led to another health subgroup at the state level, as well as a local partnership that is addressing COVID-19 testing efforts and personal protective equipment sourcing and allocation in El Paso.

"I feel very fortunate to be part of those conversations statewide and hear the details regarding what types of tests should be implemented and who should be tested," Mena said. "What I am learning statewide, I am offering that input to inform El Paso."

Locally, Mena partnered with Emma Schwartz,

president of the Medical Center of the Americas Foundation, and Tracy Yellen, CEO of the Paso Del Norte Health Foundation, to address El Paso’s needs and how the community can better respond to the pandemic.

Mena’s work also continues in building a human health risk assessment framework that incorporates various aspects of the novel coronavirus—such as dose response and environmental persistence—and host parameters or measurable characteristics related to exposure and vulnerability.

The assessment will identify factors that drive health risks so that mitigation strategies can be developed.

Coming full circle This is a role Mena has been preparing for her entire career.

Since the 1990s, the environmental microbiologist has contributed her expertise to a human health risk assessment framework on viruses so that transmission mitigation strategies could be developed. Mena also offered her expertise during the 2016 Summer Olympics in Brazil, when waterborne viruses were threatening the health of Olympic athletes.

Recently, Mena’s expertise on risk assessment is being applied toward NASA and International Space Station flight crew missions.

"I have learned so much from this pandemic," Mena said. "What’s interesting is my whole dissertation work in the 1990s was mitigating the transmission of viruses within communities. Here I am 25 years later, and this is what’s happening."

Working on these COVID-19 advisory We carry cutting-edge metering technology—capable of not only panels has proven invaluable to Mena, monitoring regular water usage, but identifying major leaks and alerts for potential tampering as well. To save time, money and not to mention the prized connections resources, trust in metering solutions from Ferguson Waterworks.

UTHealth colleagues led a recent webinar for the construction industry on workplace health guidelines.

"I’m proud of who I work for, and it’s been a great example of why UTHealth has six campuses," Mena said. "It’s not just about providing educational opportunities for students but during a practical public health crisis we are able to bring educational outreach."

Mena praised EPWater for being proactive in implementing workplace safeguards early in the pandemic.

"With the novel coronavirus, our world’s focus has primarily been on influencing the host in terms of social distancing to minimize transmission among people," she said. "We need to remember, though, the importance of the potential role of our environment, such as surfaces, to become contaminated and serve as a potential source of transmission."

| executive director report |

CONTINUED FROM PAGE 6 | executive director report this size on the fly has been a challenge. In many ways.

First, we needed to decide what we could do and what we couldn’t. We made some hard decisions, including to do as much as we could as prerecorded events instead of live. It would have been a near impossibility and extraordinarily expensive to manage nearly 170 presentations live over three days. Plus, we were advised by experts to not rely on the Internet to be fully capable for such a heavily loaded program for three days, streaming into facilities that, for security reasons, block heavy video streams. We decided to record as much as we could and make it available on demand. Then we had to get commitments from presenters to prerecord their presentations on a deadline. By the way, so far so good!

Then we needed to revise how we could meet the needs of exhibitors. This is the hard one for obvious reasons. Exhibitors want to be face-to-face with clients and potential clients at a conference. We developed

a series of new offerings to assist exhibitors present their products and information, but we also offered them the choice to move to Texas Water™ 2021. Some are all in this year, and some have moved, but at this writing, this is still a work in progress. Many have split their commitments to both years to support us and the work we do, and be ready for next year. And, some have been enormously generous in their support!

And, many of our sponsors and advertisers have stayed fully committed to this year and next. We can’t thank them enough for their trust and support.

I am not going to summarize everything that will be in the conference because it is, as they say, "a work in progress." We are still building the experience so my comments will be outdated by the time we launch the conference.

We have commitments for over 100 presentations online, which you will be able to watch on demand, at any time. Many of these are eligible for TCEQ Water and Wastewater hours. Working with TCEQ, we have crafted a process for this to work, so check online when we launch the conference for details. Plus, these

offerings are also available for engineering CEU’s.

For those who were pre-registered, we are refining the pricing to provide good value for the online presentations.

One of the real pluses is the presentations will be available on demand on your schedule over the next few weeks. And, because they are on-demand, you will be able to view more presentations than time would have permitted at the onsite conference. You will receive an email or find information online on how to access the virtual conference.

Someone recently remarked that we have planned two big conferences this year. They were right. The move to virtual has been a new experience, but everything these days seems to be a new experience. With more to come.

We think we have crafted and are still crafting a great Virtual Conference. We won’t know the real answer until after we launch and get feedback from all our "partners."

What I do know now is we took the time to not blunder into "The Abilene Paradox." We have stayed true to our purposes and our goals. We are trying to meet the needs of our many audiences, our "partners" over the last 25 years. It hasn’t been simple, easy or always clear where we are going. But we have managed to find agreement as we move through the process and that is a testament to our commitment to you.

Join us for Texas Water™ 2020 – Virtual. You will be glad you did!

I’ll "SEE" you there.

We have several safety protocols in place, but we know it will take some time to get back to what is considered "normal." We did use this pandemic as an opportunity to evaluate and update our processes and procedures. I’m sure others, like the River Authority, were not just impacted at the office, but also at the water and wastewater treatment facilities. We have all had to change the way we manage our facilities. I challenge everyone to find the opportunities during this pandemic and identify how we can continue to improve our industry.

I would also like to touch on the diverse community we have within our sector. It is important that we continue to care for and respect one another during these challenging times that our communities are facing. We should be encouraging one another and be more mindful of the impact of our words and our actions. As a citizen, and in my leadership roles at the

River Authority and as this year’s Chair, I am committed to honoring with my words and demonstrating with my actions a sincere respect for the diversity we have within our communities. I encourage each of you to make a similar commitment.

I am excited about my new role and I’m looking forward to serving as Chair in these unprecedented times. I look forward to the new opportunities we can create out of the situations we are working through together. My passion and expertise are primarily with storm water management and watershed protection, so I’m looking forward to expanding on these initiatives. I did find it interesting that while people were sheltering in place, the water quality in our creeks and rivers was much improved. Even after a stormwater event, we did not have the typically high volumes of pollution flowing into our streams. Nature really thrived as we stayed at home. My hope is, as COVID-19 emergency orders are lifted, our organization and the water and wastewater industries that we represent will continue to lead the way in advocating for and implementing innovative water solutions that will best
