Recovering the costs of building the collection system
The District’s wastewater collection system and treatment plant require significant investment to ensure they can safely, efficiently and reliably move and treat wastewater. These costs are recovered over time from owner communities through connection charges as new lands are served by sanitary sewers.
How THE charges are assessed
Connection charges are based on the size of the area covered and distance from the treatment plant, and are charged to all lands that can be served by the sewers being installed. Lands considered public rights-of-way or recognized as environmental corridors are not subject to these charges if no sanitary sewer service is being provided. The Commission adopted the regulations that govern connection charges in 2017.
Connection charges are broken down into two types: Conveyance Facility Connection Charges (CFCC) and Treatment Plant Connection Charges (TPCC).
Both CFCC and TPCC are for all new connections to the District’s system.
CFCCs have existed since the District was formed in 1930 and vary depending on the cost of facilities required to transmit the wastewater to and from the treatment plant. There are currently 30 CFCC basins throughout the District service area. Lands farther from the treatment plant require more facilities to transmit wastewater, and these CFCC rates are generally higher than for basins closer to the treatment plant.
TPCC allocates the value of the treatment plant to an area basis using estimates of average treatment plant capacity usage per lot, which applies to all new connections. If TPCC was not paid on an area basis when lands originally connected to the District’s system, a redevelopment charge may be due if lands redevelop and increase usage of the sanitary sewer system.

Unsure whether sanitary sewer connection charges have been paid for an area or property?
Owner communities, title companies, developers and others can now check with our Paid Areas Viewer.
To use the map, either type in the address or 12-digit parcel number (no dashes) in the search bar to navigate to the parcel. Blue shaded areas indicate that charges have been paid for existing connections to the sanitary sewer system. Red shading denotes that unpaid or deferred charges are owed to the District.
Note that if a parcel is being redeveloped, additional charges may be owed to the District. If you have questions or are planning a new development or redevelopment, please contact us.
