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 EchoWater Resource Recovery Facility in Elk Grove, where wastewater is treated each day and then safely discharged to the Sacramento River.
