The Hollister Urban Area Water & Wastewater Master Plan is a collaboration between Sunnyslope Water, San Benito County Water District, and the City of Hollister which addresses long-term regional water and wastewater supply and quality. It includes analysis of current and future water demand, water supplies and availability, water treatment options, wastewater treatment, and recycled water. This plan serves as the basis for all long-term water and wastewater decisions in the Hollister area.
