Recharge basins at Whittier Narrows, Los Angeles County, replenish groundwater aquifers with recycled water.

Koele Golf Course, on the Island of Lanai, has used recycled water for irrigation since 1994. The pond shown is recycled water, as is all the water used to irrigate this world-class golf course in the state of Hawaii.

Gallo Wineries and the City of Santa Rosa completed facilities for irrigation of 350 acres of vineyards with recycled water from the Santa Rosa Subregional Water Reclamation System.   The 50-year agreement is testament to the vision and long-term commitment of the parties and their faith in recycled water.

á  Oak Hill Cemetery in San José, California, irrigated with recycled water—one of over 400 landscape sites in the City on the water recycling system.

Irrigation of raw-eaten vegetables with disinfected tertiary recycled water is now accepted and practiced widely, thanks to a five-year, rigorous field validation conducted in Monterey County. 

Bahman Sheikh conceived, planned, managed, and completed the project and published papers in the technical journals regarding this critical use of recycled water.
