The purpose of the wastewater program is to collect and convey all wastewater produced within the District to the Oro Loma/Castro Valley Wastewater Treatment Plant in San Lorenzo. This is accomplished through establishing specifications for the construction of sewer lines, inspecting for compliance with those specifications, conducting preventive maintenance of the system, repairing and replacing defective elements of the system, managing flow rates to stay within the capacity of the collection and treatment systems. The collection system maintains approximately 150 miles of wastewater sewer mains and eight sewage pump stations.
