On-Site Sewage Facilities Program

LCRA’s On-Site Sewage Facilities Program includes the inspection and licensing of OSSF systems near the Highland Lakes.

The Texas Commission on Environmental Quality designated LCRA as an authorized agent to administer its 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 help protect water quality in the Highland Lakes. LCRA also has the authority to operate regulatory programs under Section 8503.004 (q) of the LCRA Enabling Legislation.

The OSSF 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.
