A new septic system in rural Liberty County runs through the county first

Most homes out past the sewer lines here run on a septic system, an on-site sewage facility, or OSSF. You can't just dig one in. Building, altering, repairing, extending, or even operating a system takes a permit and an approved site plan, and in Liberty County that approval comes from the county's own TCEQ-licensed field inspectors: Norma Ibarra works out of the Liberty office at 311 Travis Street, Ana Ramirez out of the Cleveland office at 1616 County Road 3549.

There's one narrow off-ramp. A single-family home on ten acres or more can qualify for an exemption from the permit if it clears every condition: a licensed site evaluation, every part of the system set back a hundred feet from the property lines, all effluent kept on-site, and no nuisance or groundwater pollution. Miss any one of those and you're back to the standard permit.

The trap to watch for is figuring an old system on a property you're buying is good to go. A septic built for a small cabin won't carry a full house, and a system that's been significantly altered loses its grandfathered status. Before you close on rural land, ask the field inspector what the existing system was permitted for. It's cheaper than discovering the answer after the well's already drilled.
