Environmental Protection South Carolina 4 Minutes Read ยท published February 21, 2026 Flag of South Carolina

Charleston, South Carolina requires property owners and builders to follow municipal rules for stormwater control and sewer connections to protect public health, waterways, and infrastructure. This guide summarizes the local regulatory framework, who enforces it, application steps, common violations, and how to report problems or appeal decisions. It pulls from the City code, the municipal stormwater program, and the local water utility so you can find official rules and forms quickly.

Overview of Rules and Scope

Stormwater and sewer connection requirements apply to new construction, redevelopment, changes in use, and certain private drainage or discharge activities. Local rules cover permitted connections, prohibited discharges to storm drains, erosion and sediment controls during construction, and standards for on-site detention or treatment. For ordinance text and definitions see the municipal code and utility regulations City Code - Charleston[1].

Who Enforces These Rules

  • City of Charleston Stormwater Division enforces stormwater and illicit discharge rules and inspects construction sites Stormwater Management[3].
  • Charleston Water System manages potable water and sewer connections and issues connection permits and technical standards Charleston Water System[2].
Always confirm the current permit form before starting work.
