The Rodeo Sanitary District (RSD) is an enterprise district, formed in 1939, that serves all of Rodeo and the village of Tormey, including 3,000 residents and businesses in Western Contra Costa County. Our treatment plant in Rodeo collects and treats an average of 1 million gallons of wastewater per day.

Our mission is to protect public health and the environment. We do this by collecting and treating wastewater, providing recycled water, and promoting pollution prevention.
