This office permits septic systems and takes maintenance reports for the 1 county without a local authorized agent; the other 22 permit locally.
From TCEQ's regional office directory, read Oct 31, 2026.
TCEQ Region 05 (Tyler) covers 23 Texas counties: Anderson, Bowie, Camp, Cass, Cherokee, Delta, Franklin, Gregg, Harrison, Henderson, Hopkins, Lamar, Marion, Morris, Panola, Rains, Red River, Rusk, Smith, Titus, Upshur, Van Zandt and Wood.
22 of the 23 counties permit on-site sewage facilities through a local authorized agent (a county). The remaining county has none, so the TCEQ Region 05 (Tyler) office (903-535-5100) permits systems and takes maintenance reports there.
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.
32,704 aerobic systems were authorized across the region from 2015 to 2025. In 2025, 4,211 of the region’s 4,552 on-site sewage facility authorizations were aerobic (92.5%).

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.
