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.
