Septic Services Across Horry County, SC
Most of Horry County's new growth is happening outside the sewer service area — and out there, septic is simply how new homes get built. We connect builders and homeowners across the county with local installers who work these roads every day.
Where the Sewer Ends, Septic Begins
Public sewer in Horry County serves the cities and the denser corridors — but the subdivisions, acreage lots, and new developments spreading across the unincorporated county are overwhelmingly on septic. If your lot is outside the sewer service area, a septic system isn't plan B. It's the plan, and the septic permit is one of the first dominoes in your build timeline.
The rules are the same countywide: SCDES site approval and a Permit to Construct come before the building permit on any unsewered lot. What changes from parcel to parcel is the ground itself — Horry County soils run from sandy loam to tighter clay-influenced soils, and the soil evaluation decides the system type, size, and drain-field location. Installers who work the county every week know which areas perc easily and which ones need a closer look.

Buying Land in Horry County?
Answer the septic question before you close. Ask the seller or listing agent: is the parcel inside or outside the sewer service area? Has a soil evaluation or perc test been done, and is there an existing SCDES approval? A lot priced like a bargain can turn expensive if the soils won't support a conventional system. When you request a quote through Conway Septic Pros, share the parcel location and what you know — the installer can tell you quickly what you're working with.

Horry County Septic Questions
Check with the local sewer provider for the parcel address — if the lot is outside the service area or a connection isn't feasible, you'll need an onsite septic system with SCDES approval. When in doubt, tell us the location when you request a quote and the installer can advise.
SCDES (South Carolina's environmental agency) handles onsite wastewater: site evaluation, system approval, and the Permit to Construct. The county or city building permit comes after.
No. We're a referral service — we connect you with independent local installers and are not the contractor. See How It Works for the full disclosure.
