Septic Systems in Lampasas County, Texas

A county-run program, not a regional-office default

Lampasas County is one of the roughly 40 Texas counties that has taken on TCEQ authorized-agent status for on-site sewage facility (OSSF, i.e., septic) permitting, rather than routing applications through one of TCEQ's 16 regional offices. That matters practically: the county itself reviews site evaluations, issues permits, and performs inspections, and it has adopted its own OSSF Order to do so -- a locally adopted document that incorporates Texas Health and Safety Code Chapter 366 (the state's on-site sewage disposal statute) and specifically invokes 30 TAC 285.10, the TCEQ rule that lets a local governmental entity impose septic standards more stringent than the statewide minimum. The order applies across all of unincorporated Lampasas County except for any area already regulated under a separate, existing order, ordinance, or resolution.

Fees, appeals, and what's changed recently

Under the county's program, OSSF permit fees are paid to Lampasas County directly, with an additional $10 per permit remitted to the TCEQ Water Resources Management Account as required statewide under Texas Health and Safety Code Chapter 367. If an applicant disagrees with a decision made under the county's OSSF Order, the appeal path runs to the Lampasas County Commissioners Court rather than to TCEQ itself -- a meaningfully different process than in a county where TCEQ's own regional office is the permitting authority and, by extension, the first stop for any dispute. The county's order has also been kept current rather than left static: it was most recently amended in January 2025 specifically to address wastewater flows from recreational vehicles (RVs), a sign the county continues to actively revise its program as new situations (like RV wastewater, which the standard state OSSF framework wasn't originally built around) come up in practice.

What to check before relying on septic for a Lampasas County property

1. Request the current, complete text of Lampasas County's OSSF Order directly from the county rather than relying on a summary -- this page describes the order's statutory basis and structure, not every specific numeric standard it imposes.
2. If the planned use includes an RV or other non-standard wastewater source, ask specifically how the January 2025 amendment applies, since that update was adopted to address exactly this kind of situation.
3. Confirm the county's current OSSF permit fee and the process and timeline for a site/soil evaluation directly with the county's OSSF program before budgeting for a system.
4. If a permit decision needs to be appealed, note that the process runs to the Lampasas County Commissioners Court rather than to TCEQ -- ask the county directly about the current appeals procedure and any deadlines.
