LCRA's On-Site Sewage Facilities Program allows for the inspection and approval of septic systems. LCRA is authorized by the Texas Commission on Environmental Quality 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. Also, LCRA has the authority to operate regulatory programs under Section 8503.004 (q) of the LCRA Enabling Legislation.

History of the program
LCRA's 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. State and local regulators have modeled portions of their programs after LCRA's.

Why do we have rules?
The rules limit pollution and protect the health of those enjoying the Highland Lakes.
