Start with Bexar County before installing, repairing, or renewing septic

A septic system is also called an on-site sewage facility, or OSSF. Bexar County has one path for a new system, another for a repair or change, another for renewal, and one to list an old system. Those jobs do not all use the same form.

A standard permit is renewed every five years, and the county asks for a pump receipt. Aerobic systems follow a different plan. Their permit term, service contract, and upkeep reports matter. State law also has a few narrow exceptions for old systems, certain tracts, and urgent repairs. The permit record is stronger than a seller's guess when a rural sale depends on working septic.
