DERWA (DSRSD-EBMUD Recycled Water Authority) is a Joint Powers Authority that was formed in 1995 between DSRSD and EBMUD. DERWA's mission is to provide safe, reliable, and consistent supply of recycled water, and to maximize the amount of recycled water delivered. Currently DERWA's San Ramon Valley Recycled Water Program (SRVRWP) is providing recycled water to commercial customers in Dublin, San Ramon, and Dougherty Valley.

The District is committed to supplementing its potable water supplies by supplying recycled water to commercial customers for landscape irrigation purposes. Through DERWA, the District is developing the infrastructure to supply recycled water to central Dublin, southern San Ramon and additional sites in Dougherty Valley.
