The California Association of Sanitation Agencies (CASA) is pleased to announce the 2014 Achievement Award winners. The awards honor extraordinary clean water services, programs, and projects of CASA members developing unique and innovative approaches to improving public health in the communities they serve. Presented at the January 2015 Winter Conference in Palm Springs, California, leading experts of wastewater agencies gathered during a luncheon to recognize and discuss innovative technology and outreach strategies.
Leading the way in the Technological Innovation and Achievement Award, Dublin San Ramon Services District was applauded for their Residential Recycled Water Fill Station project. Meanwhile, the Rincon Point Septic to Sewer Conversion Project by Carpinteria Sanitary District was honored under the Outstanding Capitol Project category. In addition, City of San Diego Public Utilities accepted the large agency award for Gaining Public Acceptance of Potable Reuse through Public Outreach and Education, while Delta Diablo took the prize as a small agency under the same division for their Jean-Michel Cousteau’s Global Water Education for Youth event.

Potable reuse involves the use of proven and reliable technology to purify recycled water so that it can safely supplement the drinking water supplies of communities. It is especially valuable to communities in water-scarce regions. Experience among water agencies and municipalities has shown, however, that public acceptance of direct potable reuse is one of the primary challenges facing this source of water supply.
The WateReuse Research Foundation announces the release of a how-to guide for building support for potable reuse on the statewide and community levels. Model Communication Plans for Increasing Awareness and Fostering Acceptance of Direct Potable Reuse (WRRF-13-02) provides a roadmap for advancing public acceptance of potable reuse projects by building support and awareness of existing and planned potable reuse programs and by fostering an understanding of the great need to continue to expand water supply sources.
This resource provides those involved with planning a potable reuse project with a catalog of promising and proven methods and messages for advancing potable reuse. A combination of literature review, face-to-face meetings, and public opinion research indicated that public acceptance of potable reuse can be achieved by implementing a coordinated, consistent, and transparent communication plan.

Utilities seeking help implementing ammonia criteria revised by the U.S. Environmental Protection Agency (EPA) will have several tools resulting from an experts workshop held last fall that discussed how to help reduce the burden for permittees.
The workshop, which took place in Arlington, Va., from October 28 to 29, was hosted by the Water Environment Federation (WEF; Alexandria, Va.), National Association of Clean Water Agencies (NACWA; Washington, D.C.), and Water Environment Research Foundation (WERF; Alexandria, Va.).
EPA published final national recommended water quality criteria for protection of aquatic life from the toxic effects of ammonia in freshwater in 2013. The criteria reflect new data on sensitive freshwater mussels and snails, incorporate scientific views EPA received on its draft 2009 criteria, and supersede EPA’s previously recommended 1999 ammonia criteria.
Experts from WEF and NACWA as well as WERF subscribers and state water quality professionals led the workshop. EPA technical staff also provided the agency’s perspectives and updates on implementation efforts.
The Oro Loma Sanitary District (OLSD), which provides wastewater and solid waste services to the communities of San Lorenzo, Cherryland, Ashland, Fairview, portions of Castro Valley and Hayward, and 40% of the City of San Leandro, was honored at the January 9, 2015 Awards Banquet of the California Water Environment Association (CWEA) San Francisco Bay Section. OLSD received two prestigious awards. The first award recognized the organization’s commitment to plant safety. The second recognized its innovative Zeolite-Anammox Sidestream project.
“We are honored to receive this recognition,” said Jason Warner OLSD General Manager. “These awards are terrific validation of our innovative and sustainable approach to infrastructure management.”
The CWEA San Francisco Bay Section Plant Safety Award 2014 recognizes the District for its outstanding safety record, which includes more than seven years without a lost-time injury. Safety training and incident investigations, emergency planning, hazardous materials spills planning, and a general culture of exceptional safety programs and practices all factored into choosing Oro Loma Sanitary District for this major achievement award.
The CWEA San Francisco Bay Section Research Achievement Award 2014 was awarded to the District for its participation in the Zeolite-Anammox Sidestream project, a pilot study designed to reduce the concentration of unwanted nutrients discharged into San Francisco Bay by local wastewater treatment plants. The project involves adding a separate process, in which specialized bacteria are used to convert the wastewater treatment byproducts of ammonium and nitrite into harmless nitrogen gas; the nitrogen gas is then naturally released into the air. Oro Loma was selected for the study to investigate the feasibility of the process and to determine its impact on the overall wastewater treatment process. The study is ongoing.
