Restaurants and commercial in Summerville, SC | Grease, volume and a health inspector
Commercial waste is not domestic waste with more of it. Restaurant effluent is high-strength and greasy, and a system sized on residential assumptions will foul in a fraction of its design life.

The grease interceptor is the whole game
Grease that reaches a septic tank floats, thickens, and eventually rides out into the field where it seals the trench permanently. An adequately sized, adequately pumped interceptor ahead of the tank is the difference between a field lasting twenty years and one lasting three. Most of the failed commercial systems we open failed for this reason and no other.
Sizing for a commercial kitchen
Design flow comes from seats, hours and fixture count rather than bedrooms, and the tank and field both scale accordingly. These are larger, more expensive systems, and they are permitted through SCDES on a commercial application with engineered drawings where flow crosses the threshold.
You cannot close for a week
Replacement on a working restaurant gets staged around service — night and early-morning work where the excavation allows it, temporary pumping to keep the kitchen open, and the disruptive excavation timed to your quietest days. It costs more to work that way. It costs less than closing.
