Charleston Water System provides sewer service for a smaller geographic area than our water service, so many of our water customers receive sewer service from another utility.
Our sewer service area
includes the City of Charleston, unincorporated areas in West Ashley, parts of Johns Island, and the Cainhoy peninsula.
For our water customers outside of these areas, public sewer service is provided by one of the following utilities:
Charleston Water System is the billing agent for some of these sewer providers (this noted on your bill), but we do not set rates or manage the sewer infrastructure for these agencies.
