The City of Fresno owns and maintains the sanitary collection system that serves the City and other participating agencies. The City’s collection system and other infrastructures are maintained by the Collection System Maintenance (CSM) workgroup of Wastewater Management Division. The system is comprised of approximately 1,500 mile of pipes ranging from 4” to 84” in diameter that convey over 65 million gallons of sanitary sewer per day to the Fresno-Clovis Regional Reclamation Facility. Other infrastructure includes over 23,000 manholes and 15 sewer lift stations.

CSM operators perform preventive and repair maintenance of the collection system on a daily basis as well as main line condition assessment and repairs as well as inspection of new connections to the main line. CSM respond to sewer emergencies 24/7, 365 days per year.
