The approval process depends on the type of development, as explained below.
Projects generally fall into two categories:
Water and/or sewer main extension projects
Residential or commercial development projects that require water or sewer main extensions for service and/or fire protection are done so at the developer's cost and conveyed to Charleston Water System for ownership and maintenance after construction. More info >>
New service only projects
Residential or commercial construction or renovations that require new water and/or sewer service, including fire sprinkler services, fire hydrants, and cut-in manholes where mains are already installed. More info >>
Note: Charleston Water System is legally known as the Commissioners of Public Works of the City of Charleston (CPW); therefore, all contracts and other legal documents will refer to Charleston Water System as Commissioners of Public Works or CPW.
