Rock Solid Septic & Excavation has published a South Carolina homeowner guide explaining septic repair areas, building setbacks, and the records to check before planning a garage, pool, driveway, or other yard improvement.
The licensed Spartanburg septic contractor’s new guide explains a state rule that can derail plans for a garage or a pool on ground that looks like ordinary lawn.
SPARTANBURG, S.C., Oct. 7, 2026 — Rock Solid Septic & Excavation has published a homeowner guide titled “Can You Build Over a Septic Drain Field or Repair Area in South Carolina?” on its website. The guide covers a requirement many owners learn about only after they have drawn up building plans: part of the yard has to stay open for a future replacement septic system.
State Regulation 61-56 requires new septic sites to hold suitable land in reserve. Under Section 200.7, that repair area must equal at least 50% of the size of the original system, so a system with an 800-square-foot infiltration area needs at least 400 square feet in reserve. The ground must have suitable soil and stay free of buildings and impervious surfaces. The strips of undisturbed soil between existing drain trenches do not count toward it.
An active drainfield takes wastewater from the tank today. The repair area is land reserved for a future replacement system rather than part of the operating drainfield. It may look like an unused section of the yard, but it must remain suitable for future septic construction. Owners overlook it when they sketch a detached garage or a pool because on the surface it is only grass.
“A lot of people think the septic is just the tank and the drain lines, so the rest of the yard is free,” said John (Ivan) Rusev, co-owner of Rock Solid Septic & Excavation. “Then they pour a slab for a shop right on the repair area. Five years later the drainfield quits, and now there’s nowhere to put a new one.”
The guide walks through which improvements conflict with a septic system and what to check before work begins. It covers the setbacks in Section 200.6, which keeps septic systems out from under driveways and parking areas. The same section sets a 5-foot setback from buildings and 15 feet from an inground pool.
A drainfield that fails after the reserve has been built over sends the owner back to a new site evaluation. Upstate clay narrows the choice of suitable ground, and property lines narrow it further. Some lots end up needing an engineered system, which Rusev says can cost three to four times as much as a conventional one.
The guide recommends checking septic permits and approved site plans before finalizing construction plans to identify the drainfield and any designated repair area. Rock Solid retrieves available records from SCDES at no charge, with county-specific guidance for Greenville, Spartanburg, Cherokee, Anderson, and Pickens. If records are unavailable, professional locating and marking costs $300 to $350 as of October 2026. The 50% repair-area requirement applies to new sites under the current regulation. Older properties may lack a designated area and require individual evaluation.
