Septic / OSSF
Septic system permits in unincorporated Atascosa County
If your property in unincorporated Atascosa County has no public sewer, you need a permitted septic system. You must get county approval before any work starts.
In Texas, septic systems are officially called on-site sewage facilities, or OSSFs. The Texas Commission on Environmental Quality (TCEQ) sets the state rules. Atascosa County handles permits, inspections, and enforcement for unincorporated parts of the county.
You need a permit to install, fix, change, or expand an OSSF. A licensed installer must do the work. The county sanitation office has its own form and its own fee schedule. The rules also set minimum distances. Septic parts must stay a set distance from property lines, wells, and water.
Buying rural land? If the listing mentions a septic system, ask for the permit and inspection records. A system with no permit may need costly fixes to meet today's rules. Contact Atascosa County's sanitation department for permit forms and current fees.
