From the acreage on the edges of the city to the Hill Country lots west of town, plenty of Austin-area properties run on septic, not city sewer. Cornerstone designs, installs, and repairs those systems to Travis County code, with a local team out of nearby Manchaca.
Austin sits in Travis County, where on-site septic falls under TCEQ rules administered locally. New systems need a soil and site evaluation, a permitted design, and a final inspection, and the timeline and requirements differ from neighboring counties. We work inside those rules every week.
The Austin area is a mix: established homes on septic near the city, fast-growing acreage subdivisions on the outskirts, and Hill Country lots to the west where soil can be thin over rock. That range is exactly what we’re built for. We size and design the system to the specific lot rather than dropping in a template, which matters most where the soil is tight or the lot is small.
A septic system can make or break a closing. Our inspection service documents the system’s real condition so there are no surprises at the table.
