The primary responsibility of the Collections Department is to maintain the integrity of the District’s collection system, which consists of approximately 275 miles of sanitary sewer lines, 6,022 manholes, more than 60 special structures, 13 pump stations, and several inverted siphons. The Collections crew cleans and video inspects approximately 2 million feet of sewer lines each year, and maintains records of sewer line condition. The crew partners with Engineering to establish repair and replacement priorities, and handling investigation, regulatory reporting, and claims for sewer overflows.
