Water Reuse: Sustainable Golf Course Irrigation

The clear, present and growing challenge of global water scarcity is hindering the ability to deliver water where it is needed—for both potable and non-potable use. Communities are responding to this challenge with solutions including storage, conservation, education, groundwater management and water reuse. Water reuse is a proven approach that reduces vulnerability to drought and provides environmental co-benefits.

A Team Effort

Pacific Gas & Electric (PG&E) achieved win-win results by offering the California Wastewater Process Optimi­zation Program (CalPOP). The city of American Canyon, located in the Napa Valley of Northern California, was a promising candidate for this utility-sponsored program that helps wastewater utilities reduce their energy usage and, in turn, helps PG&E meet growing demand with customer energy efficiency improvements.

Silver & Green

In February 2010, the Dempsey E. Benton Water Treatment Plant (WTP) added 16 million gal per day (mgd) of capacity to the water utility operated by the city of Raleigh, N.C. The project, situated on 55 acres in the neighboring town of Garner, N.C., represents a milestone in the utility’s history.

Quenching Thirst in the Valley

In what has become a growing trend, the new Point of the Mountain Water Treatment Plant (POMWTP) in Draper, Utah, incorporated a multi-barrier approach to address specific disinfection issues shared by many surface water treatment facilities. The Metropolitan Water District (MWD) of Salt Lake & Sandy integrated a mix of complementary treatment barriers that resolve current issues while instilling the needed capabilities to adapt to changing regulatory requirements.

A Single-Source Delivery

In December 2008, the city of Clovis, Calif., will bring a state-of-the-art sewage treatment and water reuse facility (STWRF) online to support future development in the northwest and southeast outer reaches and northeast urban centers of this bedroom community near Fresno, Calif. The 16-acre plant site is on a former almond grove and will help offset the declining supply of groundwater needed to support anticipated planned unit developments and irrigation use in existing areas.

A Neighbor-Friendly Plant

Small Town, High Tech

Prairie du Sac, a village of 3,400 located in southcentral Wisconsin, recently became one of the first groundwater-sourced communities in the U.S. to use UV technology to disinfect its groundwater.

The village’s journey to UV disinfection began when it was selected as one of 14 communities in the state to participate in a $2.3-million, U.S. Environmental Protection Agency (EPA)-funded study focusing on the role of drinking water in childhood illnesses—The Wisconsin Water and Health Trial for Enteric Risk—conducted by the Marshfield Clinic Research Foundation in Marshfield, Wis.
