Septic Systems in Travis County: What You Need to Know

A country address and no sewer line do not settle the septic question. First ask if public sewer is open or required. If septic is the right route, find the permit office for that parcel. Texas calls that office the authorized agent. Travis County handles many sites outside cities, but another local office may handle yours.

A permit is usually needed before a septic system is built, installed, changed, made larger, or repaired. The review starts with the land. Soil, slope, water, setbacks, open space, and the home plan can all shape the design. The system also needs an inspection and approval before use.

Start with the county's home OSSF page. Do not buy a system from a rough sketch alone. Basic upkeep and urgent repairs can use other steps. A short call to the permit office can keep the plan from starting at the wrong desk.
