To ensure an adequate and reliable supply of high-quality water, the water district has partnered with cities and water retailers in Santa Clara County to develop recycled and purified water supplies. In calendar year 2017, about five percent of the county’s total water use consisted of recycled water, and was used primarily for landscaping, agriculture and industrial activities.

Valley Water, in collaboration with local stakeholders, is developing a Countywide Water Reuse Master Plan, a collaborative strategy to integrate and expand recycled and purified water as a local, reliable, environmentally adaptive, drought-resilient water supply. This master plan is estimated to be completed by Summer 2021.

There are four individual Recycled Water Systems (RWS) providing service in Santa Clara County. These systems receive recycled water from a single Producer (City of Sunnyvale, Palo Alto Regional Water Quality Control Plant (RWQCP), South Bay Water Recycling (SBWR), and South County Regional Wastewater Authority(SCRWA)).
