SacSewer serves as one contributing agency to the Sacramento Regional County Sanitation District (Regional San). While we are responsible for the collection of wastewater from the unincorporated areas of Sacramento County, the cities of Citrus Heights, Rancho Cordova, and Elk Grove, and portions of the cities of Folsom and Sacramento, Regional San is responsible for the conveyance and treatment of that wastewater.

For Regional San, this includes the ownership and maintenance of larger interceptor pipes and the activities taking place at the Sacramento Regional Wastewater Treatment Plant, located just outside of Elk Grove, east of the Sacramento River.
