You Need a Permit Before Installing a Septic System in Rains County

Most of Rains County has no city sewer. That means most homes use a septic system. The official term is an on-site sewage facility, or OSSF. If your property is outside the city limits of Emory, Point, or East Tawakoni, you almost certainly need one.

Texas law requires a permit before you build, repair, extend, or change a septic system. You cannot skip this step. Rains County is an authorized agent under TCEQ rules. That means the county — not the state — handles your permit. TCEQ is the Texas Commission on Environmental Quality, the state agency that sets the rules.

If you are buying land or building a house in an unincorporated area, ask about the septic system before you close. An old or poorly installed system can cost a lot to fix. You will need county approval before any work starts. The county's environmental office handles permit applications. The TCEQ homeowner page lists the types of systems that are allowed and what inspections are required. Check both the county and the TCEQ site for current rules.
