TCEQ Region 14 (Corpus Christi) covers 15 Texas counties: Aransas, Bee, Calhoun, DeWitt, Goliad, Gonzales, Jackson, Jim Wells, Kleberg, Lavaca, Live Oak, Nueces, Refugio, San Patricio and Victoria.
All 15 counties permit on-site sewage facilities through a local authorized agent (a county), and maintenance reports go to that agent.
Reports are due within 14 days after the test (30 TAC §285.7(e)(1)(B)). No county in this region has published how maintenance providers submit the report, so every county page here says so rather than guessing.

Authorizations to Construct from the eleven annual TCEQ “Types of Systems Installed” reports, summed over the region’s counties. Surface irrigation and drip both require aerobic pretreatment. The statewide dataset has the CSV, and the 2025 report compares the regions.
The rules are the same in every county
- · An aerobic system with surface application is tested every four months (30 TAC §285.91(4), Table IV). How often systems are inspected.
- · Each report goes to the permitting authority and the owner within 14 days of the test (30 TAC §285.7(e)(1)(B)). The deadline rule.
- · A new aerobic system starts with a two-year service policy (30 TAC §285.7(c)). After that the owner renews the maintenance contract or, for a single-family home, may maintain the system themselves where local rules allow (§285.7(d)(4)). What the contract must say.
