LCRA's On-Site Sewage Facilities Program inspects and approves septic systems near the Highland Lakes.

The Texas Commission on Environmental Quality authorizes LCRA to implement on-site sewage facility rules and standards within LCRA's jurisdiction under Chapter 341 and Chapter 366 of the Texas Health and Safety Code. The rules limit pollution and protect the health of those enjoying the Highland Lakes. LCRA also has the authority to operate regulatory programs under Section 8503.004 (q) of the LCRA Enabling Legislation.

The On-Site Sewage Facility Program was LCRA's first water quality program. Since September 1971, LCRA has regulated the installation and operation of on-site sewage facilities within a 2,200-foot zone around the upper Highland Lakes and in a 2,000-foot zone around Lake Travis.
