Our History
The California Alliance for Sewer System Excellence (CASSE) was formed and first met in September 2011 in Sacramento. It was initially made up of 24 agencies in California. Together, the charter members of CASSE were responsible for operating and maintaining over 36,000 miles of gravity and pressure sewer pipe and hundereds of pumping facilities. This represents nearly one-third of all the publicly owned and operated wastewater collection facilities in California. CASSE was created with a vision to reduce sanitary sewer overflows, protect surface waters, help further develop the workforce, and to drive performance up and costs down through implementing agreed best practices at any location.
