Septic Tank Companies in South Carolina
193 septic service companies across 100 cities — approximately 40% of South Carolina homes use septic systems
South Carolina's septic systems are regulated by the South Carolina Department of Health and Environmental Control (DHEC), which handles permitting and inspections through its regional offices across the state. With approximately 40% of homes on septic — one of the higher rates in the Southeast — onsite wastewater is a critical issue, particularly in rapidly growing suburban areas around Charleston, Greenville, and Myrtle Beach. South Carolina's Lowcountry features sandy soils with extremely high water tables and tidal influence, while the Upstate Piedmont region has the familiar tight red clay soils that drain poorly, and the Sandhills region between them has rapidly draining sandy soils.
