Well & Septic Service in Sullivan’s Island, SC
Looking for well or septic help on Sullivan’s Island? The island is served by public water and public sewer, so the right call is often a sewer-line, building-sewer, drain, water-service, backflow or excavation professional rather than a conventional septic-pumping company.
Important local note
Town code generally restricts private septic tanks and similar private sewage-disposal facilities and requires applicable occupied properties to connect to the public sewer system.
What Sullivan’s Island properties actually use
Public water and public sewer change the service question.
The Town’s Water & Sewer Department manages drinking water and wastewater treatment. Sullivan’s Island currently purchases its primary water supply from Charleston Water System, while the Town maintains two deep wells for emergency water pressure—not as ordinary private residential well service.
On the sewer side, Town code requires applicable occupied buildings to connect to public sewer and generally restricts septic tanks, cesspools and similar private sewage-disposal facilities. That means many searches for “septic service” are really private building-sewer or drain problems.
Building Sewer & Cleanout
Problems between the structure and public sewer connection may require diagnosis, cleaning, repair or replacement on the private side.
Sewer Backup & Drain-Line Issues
Recurring backups, slow drainage or suspected line damage can require camera inspection, cleaning, plumbing repair or excavation.
Water Service-Line Leaks
Leaks on private water piping, service lines or valves may require plumbing repair even though the Town manages the public water system.
Backflow & Irrigation Connections
Irrigation and certain water-service configurations can involve backflow-prevention requirements and approved testing or installation.
Before calling a septic company
First confirm whether there is actually a septic system to service.
Sullivan’s Island Town Code §18-5 restricts private sewage-disposal facilities, including septic tanks and cesspools, except as otherwise provided in the chapter. Section 18-6 requires applicable occupied properties to connect to the public sewer system.
Private-side service needs
What a contractor may actually need to inspect or repair
The correct provider depends on where the problem is located and whether it involves plumbing, the private building sewer, a water-service line, excavation or a Town-owned component.
Sewer Camera & Line Diagnostics
Identify obstructions, damage, offsets or other issues before deciding whether cleaning or repair is appropriate.
Building Sewer Repair
Repair or replace damaged private sewer piping connecting the building toward the public sewer system.
Excavation & Line Replacement
Open-trench utility work may be needed where buried water or sewer piping cannot be repaired from inside the structure.
Water Service-Line Repair
Address leaking, damaged or deteriorated private water piping and related fittings or valves.
Backflow / Irrigation Work
Install, repair or test appropriate backflow assemblies where required for irrigation or other water connections.
Unknown / Legacy-System Questions
If records or site conditions suggest an old or unusual onsite system, verify the property setup and applicable Town requirements before work begins.
Know who owns the problem
Public-system issue or private-property repair?
The Town manages the municipal water and wastewater systems, but Town code places the cost and expense of installing and connecting the building sewer on the property owner. Before authorizing excavation or major line work, determine whether the affected component is Town-owned infrastructure or part of the private connection.
For water-service questions, the Town publishes information about the customer shutoff valve near the meter and directs residents to Water & Sewer staff when they have trouble locating or operating it.

Who pays for the building sewer connection?
