Storm Drainage in Charleston, SC
Pipe repair, catch basins, and outfall work for properties across Charleston and Charleston County. Local team, own equipment, direct execution.
Charleston's peninsular geography and chronic tidal flooding create some of the most challenging storm drainage conditions on the East Coast.
Charleston properties don't just deal with rainfall - they battle king tides that back up drainage systems twice a month, even on sunny days. The city's peninsular layout means stormwater has limited escape routes, and aging infrastructure struggles with sea level rise that's accelerated to nearly an inch every three years. Your drainage system isn't just moving rainwater anymore; it's fighting a constant battle against tidal intrusion.
Charleston County's MS4 permit puts the compliance burden on property owners, requiring functional catch basins and clear outfalls year-round. The pluff mud and fill soils throughout the Lowcountry create unstable conditions for underground infrastructure, leading to pipe settlement and joint failures. Meanwhile, the Dutch Dialogues adaptation plan is changing how the city approaches drainage, but existing properties still need systems that work today. Whether you're managing a historic downtown building or a West Ashley shopping center, your storm drainage needs to handle both traditional rainfall and the new reality of frequent tidal flooding.
What storm drainage looks like in Charleston.
Tidal Backflow Prevention
We install and maintain tide gates and backflow preventers designed for Charleston's twice-daily tidal cycles. These systems stop salt water from backing up through your storm drains during king tides and storm surge events.
Pluff Mud Excavation & Pipe Replacement
Our equipment handles the challenging pluff mud conditions throughout Charleston County. We replace failed storm pipes and regrade systems to work with local soil conditions and tidal fluctuations.
Catch Basin Rehabilitation
We repair and replace catch basins damaged by salt water intrusion and settling fill soils. Our work meets Charleston County MS4 requirements for functional stormwater collection points.
CCTV Inspection & Hydro-Vac Cleaning
We use camera inspection to identify root intrusion and pipe damage common in Charleston's older developments, then hydro-vac clean systems clogged with pluff mud and tidal debris.
We're based in nearby Bluffton and understand the unique challenges of Lowcountry drainage systems.
When your downtown Charleston property floods during a king tide, you need someone who can be there within the hour, not someone calling around for local subcontractors. We know the difference between a drainage problem and a tidal intrusion issue because we work in these conditions every day. Our crews understand how Charleston's pluff mud behaves, why your pipes settle differently here than they would inland, and what the county inspectors expect to see when they show up.
