CONCORD, NH, AUGUST 25, 2016 — The New Hampshire Department of Environmental Services (NHDES) and Saint-Gobain Performance Plastics are today announcing that Saint-Gobain Performance Plastics has arranged with Pennichuck Corporation to secure bids to extend the Litchfield Public Water System to allow for the connection of up to 360 Litchfield homes and businesses that are currently on private wells. The cost, phasing, and timing of the project will be dependent on the bids received and the construction firm selected.

The private drinking water wells serving 124 residences and businesses in the Litchfield area have tested at or above 70 parts per trillion (ppt) for perfluorooctanoic acid (PFOA), which is the New Hampshire Ambient Groundwater Quality Standard and the U.S. Environmental Protection Agency (EPA) Health Advisory level for PFOA in drinking water. The State of New Hampshire has adopted that level as the state’s Ambient Groundwater Quality Standard under emergency rulemaking. Due to the close proximity of the remaining 236 private wells, Saint-Gobain Performance Plastics has agreed that the scope of the project bid should include water line extensions so that all residences and businesses in that area can be connected to municipal water.

“We appreciate Saint-Gobain’s willingness to collaborate with the state to achieve our mutual goal of assuring clean drinking water for all area residents despite the fact that we have not concluded our investigation,” said Tom Burack, Commissioner of NHDES. “We will continue to work with Saint-Gobain and all of the affected towns to ensure ongoing access to clean drinking water throughout the investigation process.”

In May 2016, Saint-Gobain Performance Plastics agreed to fund the engineering design work by Pennichuck Corporation for the potential expansion of the existing public water system in Litchfield in addition to funding the provision of bottled water to homes having elevated PFOA levels in their private wells in the vicinity of the company’s Merrimack plant.

“Our primary concern has been to ensure the residents of Litchfield have access to clean drinking water and we remain committed to making that happen,” said Tom Kinisky, President and CEO of Saint-Gobain Performance Plastics. “We are pleased to be moving forward, under agreement with the state, to help provide permanent public water supply connections for all of the affected residents of Litchfield.”

LEXINGTON, KY, AUGUST 25, 2016 — The Kentucky Public Service Commission (PSC) has announced its approval of a settlement granting Kentucky American Water a rate adjustment for water bills that will increase its annual revenue by $6.5 million, which is slightly less than half the amount the company requested when it filed the case on Jan. 29 of this year. As a result of the rate adjustment, the monthly bill for an average residential water service customer using 4,136 gallons of water per month will increase from $34.41 to $37.38 – or $2.97 more per month – effective Aug. 28.

All parties involved in the rate case proceeding – Kentucky American Water, the Kentucky Office of the Attorney General, the Lexington-Fayette Urban County Government and the Community Action Council for Lexington-Fayette, Bourbon, Harrison and Nicholas Counties – reached a settlement in the case in July, which was subject to PSC approval.

The company requested the rate adjustment primarily due to the $79 million in capital improvements it has made since 2012. These improvements include projects such as replacing aging water mains, upgrading pumps to more efficient models, and constructing a new $15 million filtration building at the Richmond Road Station water treatment plant in Lexington to replace a 90-year-old structure. Before the 2016 case, the last time the company requested a rate adjustment was in December 2012.

“Ongoing investment in water system infrastructure is absolutely essential in order to maintain quality, reliable water service for our customers,” said Nick Rowe, president of Kentucky American Water and senior vice president of American Water’s Central Division. “While we continue to make prudent investments in the water systems that serve our customers, we are also cognizant of the need to maintain affordable rates, which is why we are also committed to performing as efficiently as possible. We have maintained essentially flat operational expenses since 2012, and our teams continue to work harder and smarter to stay on that same path.”

DENVER, CO, AUGUST 24, 2016 — CH2M and Parsons, as part of a joint venture team, have been selected by the District of Columbia Water and Sewer Authority (DC Water) to perform program management services for the development and implementation of DC Water’s capital improvement program (CIP)—a $1.3 billion water and wastewater infrastructure program focused on repair and replacement of mostly underground infrastructure in Washington, D.C., and neighboring jurisdictions.  

The three-year contract, with options for renewal up to two years, combines two separate program management contracts into one large program – providing greater efficiencies in delivery and cost. The CIP includes the planning, design and construction of linear and vertical infrastructure in the water and wastewater service areas, including piping, pumping, storage and other appurtenance structures, such as hydrants, valves, inflatable dams, diversion structures and manholes. The program includes rehabilitation or replacement of small- and large-diameter water mains; rehabilitation of water, sanitary and storm pumping stations; rehabilitation of minor and major sewers and storage facilities; and condition assessments of water and wastewater buried infrastructure, pumping stations and storage facilities.

“CH2M has worked with DC Water for many years on capital improvement projects and most recently has been leading the utility’s Asset Management Program,” said Peter Nicol, CH2M Global Water Business Group President. “Aging underground infrastructure is a national problem and leads to disruptions in service and threatens water quality. We are excited to help DC Water tackle the complicated repair and replacement of its aging underground water and wastewater infrastructure to ensure local communities have access to safe drinking water and sanitation systems.”

Michael Walsh, Parsons Group President, added “Our team looks forward to working collaboratively with DC Water on this major program that will significantly benefit the DC community. We too have worked with DC Water on numerous projects, including the Blue Plains Advanced Wastewater Treatment Facility and the DC Clean Rivers Project.”

Repair and replacement strategies are complicated in dense urban areas with complex underground infrastructure, and therefore must be coordinated carefully with a wide variety of stakeholders. As the CIP program manager, the CH2M/Parsons JV team will also help DC Water coordinate with stakeholders throughoutWashington, D.C. neighborhoods.

LAS VEGAS, AUGUST 24, 2016 — Xylem will share expertise and highlight cutting-edge, sustainable solutions to optimize the efficiency of ozone oxidation and disinfection processes at the International Ozone Association’s Pan American Group Conference taking place in Las Vegas, Nevada next week (August 28-31). The IOA-PAG Conference brings together industry leaders to share the latest insights on the application and performance of ozone. The event will feature technical presentations from Xylem’s senior treatment engineers and product development specialists, as well as a showcase of Xylem’s advanced ozone technologies at Xylem’s booth #36.

Achim Ried, chief engineer with Xylem’s treatment business, will examine “Oxidation-enhanced biologically active filtration for drinking water.” Chemical and biological contamination in drinking water poses a significant public health risk and plant operators require a treatment system that allows them to produce a safe and reliable supply of clean water. Xylem’s Leopold Oxelia is a multi-barrier solution; an oxidation-enhanced, biologically active filtration system that enables the production of a safe and reliable supply of clear and biologically-stable, treated water with no taste or odor issues.

“Leopold Oxelia’s oxidation step can include ozone, ozone-based advanced oxidation processes (AOP) or ultraviolet (UV)-based AOP,” explained Ried. “The system offers the flexibility to efficiently and effectively address a wide range of treatment requirements, producing biologically stable and safe drinking water.”

Achim Ried will also present on “Classic ozonation versus AOP for micropollutants in municipal wastewater for reuse applications.” This paper reviews several studies benchmarking the use of ozone, ozone with hydrogen peroxide (AOP) or UV-based AOPs for the treatment of secondary effluent to produce water that can be reused for irrigation purposes or in combination with membrane filtration for indirect or direct potable reuse. In addition to examining life-cycle costs and the treatment efficiency of these solutions, the presentation will also provide valuable insights on optimizing the efficiency of a reuse treatment train using ozone or AOP.

Xylem sales and application engineer for ozone, Wiebke Rand, will present a study entitled “A computational fluid dynamics (CFD) model for the estimation of ozone mass transfer in industrial scale reactors to support energy efficient reactor design.” The study aimed to develop a model capable of assessing the ozone mass transfer efficiency for drinking and wastewater applications in order to optimize the energy efficiency of ozone treatment processes.

“Computational fluid dynamics is a state-of-the-art tool designed to monitor factors influencing mass transfer efficiency including: liquid and gas flow, ozone dose, water characteristics and water-specific ozone kinetics”, said Rand, “This presentation will review the results of CFD simulations carried out in pilot testing and detail how mass transfer performance can be predicted in order to inform the design and optimization of ozone contact tanks.”

Tony Zhang, product development with Xylem’s Leopold brand will present a paper entitled “Integrated ozone enhanced biofiltration system for municipal water reuse – Design & advanced system control considerations.” Wastewater reuse applications today look beyond non-potable usage treatment requirements to advanced treatment processes for direct and indirect potable reuse. The removal of micropollutants from wastewater using physical separation processes can be energy intensive however.

“This presentation will look at how an alternative treatment train incorporating ozone and biological activated filter (BAF) can significantly reduce capital and operating costs while effectively controlling effluent by-products,” explained Zhang.

A technical session exploring ozone and biofiltration applications will be moderated by Keel Robinson, North America water reuse leader at Xylem. The session will run from 2-5.15pm on Monday 29^th August.

CALIFORNIA, AUGUST 23, 2016 — The first of several East Porterville neighborhoods that have been without a safe water supply for up to three years was connected to the Porterville city water supply Aug. 19, through a multi-phase project designed to provide a reliable water supply to an area called “ground zero” of the state’s severe drought.

The East Porterville Water Supply Project is a joint effort of the California Department of Water Resources (DWR), the State Water Resources Control Board (SWRCB), the Governor’s Office of Emergency Services (EOS), the City of Porterville, and Tulare County.

As the drought worsened across California, the Tulare County community of East Porterville became the poster child for severe impacts. Many residents found that their wells had either dried up or contained a high concentration of nitrates due to the dropping water table. Since 2014, hundreds of homes without safe water have subsisted on water deliveries, estimated by DWR to cost the state $650,000 per month. Connecting these homes to the Porterville city water system will return their home taps to normal operation and end the unsustainable deliveries.

Phases 1A through 1E of the project will provide connections for approximately 500 homes. Phase 2, to take place in 2017, will connect up to another 1,300 homes.

To qualify for the city water supply, residents must agree to have their property eventually annexed by the City of Porterville.  They will not be charged the cost of connection, but will pay monthly water bills going forward. Property owners who need help completing the paperwork can get assistance from several non-profit organizations, including Community Services Employment Training, the Community Water Center, Self-Help Enterprises and Porterville Area Coordinating Council.
