3:00 p.m.      Farm Bill/Conservation

Chi Ho Sham, Eastern Research Group

Abstract: On December 20, 2018, the President signed the Agriculture Improvement Act of 2018, commonly known as the Farm Bill. That date marked the culmination of an extensive, long-term, and successful effort by American Water Works Association (AWWA) to make source water protection a priority within U.S. Department of Agriculture (USDA) conservation programs – and to designate significant funding towards those efforts.

Under the 2018 Farm Bill, 10 percent of spending on Conservation Title programs is to be directed to source water protection, providing at least $4 billion over the next 10 years. These programs assist farmers, ranchers, and forest landowners protect and enhance environmental outcomes that have benefits both on and off-farm. Moreover, there is a now a directive for USDA to work closely with utilities to identify and prioritize areas that need source water protection.

In addition to the funding and prioritization successes, AWWA was also successful ensuring that utilities can join the state and local groups that decide how, where, on what, and how much of the conservation funds go toward source water protection. The Natural Resources Conservation Service (NRCS) administers most of USDA’s conservation programs and it is vital for water utilities to work with NRCS to address nonpoint sources of contaminants of concern such as nutrients, sediment, and chemicals.

The purpose of this presentation is to provide information to water utilities on resources and opportunities to work with NRCS state technical committees and local work groups to help facilitate discussion and implementation of conservation practices to protect source water. A number of resources will be referenced, outlined, and discussed.

3:30 p.m.    Seasonal Variations of DBP’s in a Large Water Supply

David Reckhow Ph.D., Professor University of Massachusetts, Department of Civil & Environmental Engineering

Abstract: Disinfection byproduct (DBP) precursors originate in large reservoirs from at least three types of sources: (1) watershed or allochthonous, (2) algal or autochthonous, and (3) bottom sediments or benthic. The properties of the bulk natural organic matter (NOM) and the DBP precursor content of that NOM are unique to each source. Knowledge about the relative importance of these three sources would be valuable in understanding the natural variability in DBP precursor occurrence and in managing source waters for the purpose of minimizing DBP precursors. In this study, we used temporal and spatial water quality data from a drinking water reservoir to shed light on autochthonous and benthic sources of NOM and DBP precursors. Combining conventional water quality parameters with DBP precursor analysis can facilitate a more comprehensive understanding of limnological factors that define DBP precursor levels. These data were compared with known properties of NOM and related natural biochemical parameters. From this analysis, we conclude that algal-dominated NOM contributes disproportionately to dihaloacetonitrile precursors as well as ultraviolet-absorbing substances. The sediment-dominated precursor behaved like a mix of the other two, but most resembled the watershed NOM.

4:00 p.m.   DBP Removal from Bench Sale to Design: How to Use Bench-scale Results to Make Timely Decisions  

Russell Ford Ph.D., PE, BCEE, Jacobs

Abstract: This presentation will focus on two case studies where bench- scale testing was used to evaluate disinfection by-production treatment alternatives. Mathematical models were used to predict DBP formation using the results of the bench-scale testing. The Poughkeepsie Joint Water Project Board (JWPB) implemented the use of chloramines as a distribution disinfectant in the fall of 2006. The JWPB initiated this project in 2010 due to operational and water quality challenges within the City and Town distribution systems. The water quality problems were nitrification, lead and copper violations and dirty water complaints. The problems were associated with dead-ends in the distribution system, unlined cast iron water mains, varying operating schemes and issues with wholesale customers. This project was to assess options for returning to free chlorine at the secondary disinfectant. Two seasons of bench-scale testing and DBP modeling were conducted to assess the effectiveness of various treatment alternatives for reducing disinfection by-product (DBP) formation with free chlorine. The treatment alternatives included enhanced coagulation with alum, ferrous sulfate, and polyaluminum chloride (PACl); oxidation using chlorine dioxide (ClO2) and ozone; organics removal using MIEX; and various combinations of the above. Simulated distribution system (SDS) testing was conducted to measure total trihalomethanes (TTHM) and five haloacetic acids (HAA5) throughout a 12-day period. These results were used to calibrate DBP prediction models and then used to simulate locational running annual average (LRAA) values for TTHM and HAA5 in the distribution system.

A similar case study will be presented for the Middlesex Water Company’s CJO Ozone plant upgrade. Bench-scale work conducted in 2013 and 2016 was used to make a recommendation for ozonation. The plant is currently conducting a year-long pilot test to verify ozone and biological active filtration for DBP reduction. The mathematical models developed at the bench-scale are also being verified by the data being obtained for the pilot- scale.

4:30 p.m.    Emerging Trends in the Wild World of Water Rates

Dave Fox, Raftelis          

Abstract: This presentation will give participants an overview of recent trends in the wild world of water rates. Topics covered will involve innovative and emerging rate structures, seasonal rates, billing frequencies, affordability programs and assistance, and regional and national metrics with regard to water rates and structures. Participants of this session will leave with an understanding of emerging water rate and rate structure trends, as well as what is making these trends successful or unsuccessful, and how these lessons learned can be utilized within the participants’ organizations.

9:15 a.m.    Assessment of Granular Activated Carbon and Anion Exchange Resins for Treatment of Per-and Polyfluoroakyl Substances (PFAS) in Drinking Water  

 Russell Ford Ph. D., PE, BCEE, Jacobs

Abstract: The abstract provides an unbiased comparison of adsorption technologies with a focus on life cycle performance and costs. This is not only important for treatment Perfluorooctanoic Acid (PFOA) and Perfluorooctane Sulfonate (PFOS), but as state-level regulations incorporate drinking water guidance values or limits for additional Per- and Polyfluoroalkyl Substances (PFAS), adsorbent technology selection is critical. This presentation will present current PFAS regulation updates, compare technical performance and projected life cycle costs for different Granular Activated Carbon (GAC) and for Anion Exchange Resin (AEX) based water treatment systems, and discuss integration into existing system infrastructure.

Per- and polyfluoroalkyl substances (PFASs, aka PFCs) related to aqueous film forming foams (AFFF) and a variety of widespread industrial activities have been identified as compounds of interest in drinking water supplies in the US and are generally considered emerging contaminants due to their regulatory uncertainty. PFAS are the “active ingredient” in AFFF and have been found to be present at fire fighter training areas, fire stations and related storage facilities (DoD, civilian and others), at sites where petroleum fires were extinguished or suppressed using foam (automobile and aircraft crashes, petroleum handling facilities, refiners and aircraft hangers) and storage at shore facilities for tankers and large ships. Additionally, these widely-used chemicals are common in industrial applications, such as water and grease repellent coatings, adhesives, and sealants, especially in the carpeting, fabric and paper and packaging industries. An evolving body of toxicological and risk assessment knowledge emanating from academia is driving regulatory uncertainty. Regulatory agencies are actively defining drinking water guidelines, which vary across state and national boundaries due to differences in derivation methodology.

Treatment technologies that are emerging as the most reliable and effective approaches dominantly revolve around sorption, either using granular activated carbon (GAC) or anion exchange (AEX) resins. The assessment of the life cycle costs for each of these competing systems must take into account the engineering design, installation, media costs, operation and maintenance requirements, regeneration carbon footprint, waste disposal and overall longevity of systems. This presentation will summarize available information from published sources, as well as internally- generated data, relating to life cycle costs for GAC and for AEX resin-based water treatment systems. Integration of treatment into existing water systems is critical for success and will be discussed.

9:45 a.m.   PFAS Case Studies

Matthew George, PE, Hazen and Sawyer

Abstract: The health effects and occurrence of perfluoroalkyl substances (PFAS), as well as other emerging contaminants of concern in drinking water supplies, has received significant attention lately.

This presentation will build on the previous speaker’s discussion on technologies for PFAS control, and focus on implementing comprehensive and flexible approaches to addressing PFAS and PFOS in drinking water sources focusing on developing sound treatment strategies designed to address near-term, long-term, and comprehensive strategies for addressing threats from multiple contaminants in water supplies, using three case studies from Alabama, North Carolina, and New York.

In Alabama, the case study focuses on a water treatment facility utilizing conventional treatment with MIEX added in recent years for disinfection byproduct precursor removal. In North Carolina, the case study focuses on treating PFAS compounds (mainly GenX) within a matrix of often competing water quality goals. Finally, in New York, a town is evaluating the possibility of “taking control of their water destiny” by expanding the supply of

water from a town-owned reservoir in their system. Through due diligence testing, PFOA and PFOS were detected in the reservoir water supply at elevated levels, likely from use of a nearby fire- fighting training center.

By blending these three case studies, attendees will be exposed to the current state-of-the-art related to regulatory approaches, potential future PFAS related concerns (beyond PFOA and PFOS), and strategies for developing short- and long-term approaches to addressing these contaminants of concern within the context of the currently on-going national conversation and an uncertain regulatory future.

10:15 a.m.   Great Hill Tunnel Project Phase II-Tunnel Rehabilitation and Pipe Sliplining/ Replacement

Rose M. Gavrilovic, PE, South Central Connecticut Regional Water Authority

Abstract: The Great Hill Tunnel (GHT) system, constructed in the late 1920’s is owned and operated by the South Central Connecticut Regional Water Authority (RWA). It is a 100 MGD, a 6’-4” wide by 6’-4” high, 2,700-foot long concrete-lined tunnel, transitioning to a 48-inch CIP. After a leak was discovered on the 48-inch cast iron pipe (CIP) that transports raw water from its largest reservoir to a treatment plant which serves over 60 percent of its 430,000 customers, the South Central Connecticut Regional Water Authority (RWA) was faced with a critical, complex and challenging emergency repair that was essentially completed within six months at a cost of approximately $15 million. Emergency repairs to the tunnel system required the design and construction of a temporary bypass system that could handle transporting 40 million gallons of water a day. The bypass system needed to be operational in order to perform the tunnel restoration and complete the installation of a structural liner on the 48-inch CIP under a 30-foot embankment leading to the quarry’s main road and rail system. The leak in the CIP was the result of a diver’s weight belt being dropped at the transition from the tunnel to the pipeline some 45 years ago during a lifeline rescue.

At ATCAVE in February, RWA and Tighe & Bond presented the issues of the known tunnel leak and the new CIP leak, and the challenges with installing a bypass system. This presentation will focus on the next phase of the project – the fix. This included the complete rehabilitation of the tunnel, sliplining of a portion of the 48-inch cast iron pipe extending under a main quarry road and rail system, replacing the leaking section of pipe and providing redundancy where possible for the future. This phase of work also had its challenges and urgency to complete prior to the high- demand season.

11:00 a.m. Pioneering Water Loss Control-Several States Advance with Technical Assistance Programs

 Drew Blackwell, Cavanaugh     

Abstract: There have been significant evolutions in water loss policy and regulation in the last 10 years. There is a growing recognition among the regulatory and infrastructure funding community that widespread adoption of effective utility management practices for water loss control have a measurable and meaningful impact as many states are ramping up technical assistance programs to build capacity – technical, managerial and financial – in the water utilities. These states recognize the foundational need for education, training, and validation per the AWWA M36 auditing and loss control methodology. This leads to the question, what is the cost of doing nothing?

Can a state afford to ignore the benefits which extend from resource conservation, to financial gain, to ratepayer equity, to extended asset life? California and Texas were the first states to

adopt M36 as the required methodology. More recently, Georgia, Tennessee, and Wisconsin have joined them in adopting the M36 requirement— with California, Tennessee, Georgia, and the Delaware River Basin Commission (DRBC) using the AWWA Free Water Audit Software. M36 auditing is incentivized in New Mexico via consideration for new permit applications, in North Carolina via priority points for SRF applications, and in South Carolina via incorporation into annual surveys conducted by state inspectors.

New Mexico, Georgia, Hawaii, California, and Colorado have instituted formal water loss technical assistance programs that are full scale. As of 2017, several other states have implemented pilot scale water loss technical assistance programs – Arizona, Florida, North Carolina, Utah, Washington, and Wisconsin. Beyond that, there are at least 10 other states evaluating policy revisions regarding water loss control. Given this accelerating rate of adoption – this presentation aims to provide an update on the national water loss movement and what is on the horizon.                             

11:30 a.m.   AWWA’s New Positions on Non-revenue Water Performance Indicators  

 George Kunkel, PE, Kunkel Water Efficiency Consulting

Abstract: The American Water Works Association (AWWA) has been the leading force in the North American drinking water industry developing and advocating for best practice methods for water loss control. Since 2003, AWWA has advanced a best practice water audit method, and – since 2006 – a free software tool for

water utilities to compile this water audit. The method includes an array of effective performance indicators, but also includes two percentage indicators. One of these is a volumetric percentage performance indicator (VPPI) which has a form similar to the “unaccounted-for” water percentage employed by many regulatory agencies in US states. Prior to launching work on the next (5th) edition of the AWWA M36 guidance publication Water Audits and Loss Control Programs, and the next (6th) version of the AWWA Free Water Audit Software, AWWA’s Water Loss Control Committee (WLCC) determined to reassess its position on NRW percentage indicators and other forms of indicators for water efficiency assessments. In 2016 the WLCC formed the NRW Performance Indicators Task Force (PITF) to take on this charge, and to issue a new position on NRW PIs by July 2019.

The PITF set criteria for PIs recommended for use as:

  • Technically rigorous
  • Easily understood by a wide range of stakeholders; including water utilities, regulatory agencies, customers, elected officials, and the media
  • Suitable to use for target-setting and progress monitoring of loss reduction activities: i.e., they must be actionable
  • Suitable for the state of readiness of North American water utilities and regulatory agencies; recognizing that many water utilities are new to water loss control and many regulatory agencies need a straight-forward and efficient means for water audit data collection and loss control monitoring that can be readily implemented.

This presentation will discuss the factors around NRW PIs and will give a glimpse into the new position developing under the PITF. Also, a series of data trends will be presented for various indicators by applying data from hundreds of validated water audits that now is available from several US states where AWWA water auditing and data validation are required. The presentation will update the audience on AWWA’s effort to move beyond dated and imprecise NRW percentage indicators and to identify new innovative ways of assessing water loss in drinking water utilities.

9:15 a.m.     2020 DOE Pump Regulations & the Energy Rating Initiative

Mark Chaffee, Taco Inc.

Abstract: In the United States and worldwide, energy usage for the movement of water accounts for a significant percentage of the total energy consumed. As part of the Energy Policy and Conservation Act, the U.S. Department of Energy (DOE) has adopted new energy conservation standards for certain clean water pumps. Manufacturers must comply with the standard levels set forth by January 27, 2020. This seminar will provide an overview of these standards, including what products are covered, along with how the water and pump industry is responding to comply and develop parallel labelling and lab certification programs to enable utility incentives for the purchase of certain energy efficient pumps within scope.

9:45 a.m. Collaborative Approach to Water Resources Management for Pomeraug River   

David Radka, Milone & MacBroom Len DeJong, Pomeraug River Watershed Coalition

Abstract: In an effort to relieve stress on Pomperaug River flows during periods of low stream flow, Town of Southbury, Heritage Village Water Company (“HVWC”) and Pomperaug River Watershed Coalition (“PRWC”) representatives forged a partnership with the

support of Milone & MacBroom Engineering Consultants to develop pro-active approaches to reduce public water supply demands on the Pomperaug aquifer, which sustains low flows in the river. These new safeguards include the development of the HVWC Pomperaug River Low-flow Operations Plan (“Low-flow Plan”) and submission to the CT Public Utilities Regulatory Authority of a new water service agreement with CPV Towantic, LLC that utilizes an out-of-basin water supply for their Oxford facility during typical seasonal river low-flows. Without these safeguards, the flows in the river would be lower and potentially detrimentally affect river habitat and the overall health of the river.

The Low-flow Plan establishes three river discharge flows and low-flow mitigation thresholds to provide HWVC customers and private well owners with an increasing level of awareness on the status of river flow. Each mitigation threshold has a corresponding Action Level that requests water users to voluntarily comply with expanding water conservation measures. The Low-flow Plan also includes the potential of increasing the transfer of water through a pipeline interconnect from the CT Water Company (“CWC”) Central System not associated with the Pomperaug aquifer supply. Public communication of these Action Levels is through postings on each participating organization’s website as well as print media and if required, Town of Southbury’s “Code Red” notification alert system.

This presentation will review the science utilized to support the development of the Low-flow Plan including a 2007 UMASS Instream Habitat Study which was updated during the project as well as the use of drought hydrographs. The collaborative partnership approach to the Low-flow Plan as well as the effort to develop and secure regulatory approval for the revised Water Supply Agreement will also be discussed as will the communication to the public of the various Action Levels.                                 

10:15 a.m. Security and Awareness Training    

Sal Nesci, South Central Connecticut Regional Water Authority

Abstract: As an industry, we are dedicated to providing a reliable supply of high-quality drinking water to our valued customers in communities across America. However, providing high quality drinking water is a complex process that requires the use of numerous interconnected vital computer networks. With cyberattacks on the rise, the water utility industry must take steps to educate their staff in order to prevent malicious attempts to access or damage mission critical computer networks.

By working in partnership with other dedicated community stakeholders, the water utility industry can safely reduce its exposure to cyberattacks while enhancing its cyber and physical security profiles. Cybersecurity involves preventing, detecting, and responding to cyberattacks that can adversely impact individuals, organizations, and the community. Cyberattacks can lead to the loss of money, theft of personal information, and damage to the organization’s reputation.

Security Awareness Training will focus on three vital areas: cybersecurity, physical security, and active aggressors. As industry leaders, we must continuously engage in the process of risk assessment in order to identify and mitigate vulnerabilities. Law enforcement and security professionals rely on the public’s assistance to detect and report suspicious activity. This basic training program is designed to heighten staff member’s safety and security awareness while reinforcing the importance of being situationally aware.
