Contributing Agencies

Regional San’s contributing agencies include the Sacramento Area Sewer District and the cities of Folsom, Sacramento and West Sacramento. These agencies collect and channel wastewater to Regional San’s interceptor pipelines. The interceptor pipelines transport the wastewater to the Sacramento Regional Wastewater Treatment Plant, in Elk Grove, where approximately 124 million gallons of wastewater are treated each day and safely discharged to the Sacramento River.
