Approval Process for New Development

General Requirements
Developers, their engineers and contractors are responsible for meeting our Minimum Standards and following established Developer Policies and Procedures for payment of fees and project submittals.

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.
