Rules and Regulations

The Texas legislature passed a law, HB 1875, in 1987 to regulate on-site sewage facility (OSSF) systems statewide. The law allowed regional and local governments such as counties, cities, river authorities and special districts to implement and enforce on-site sewage regulations with approval and oversight by the Texas Commission on Environmental Quality (TCEQ).

Although the state law has since been modified and expanded, its basic intent remains. The state sets minimum standards, and local authorities can adopt more stringent rules if the TCEQ approves them.
