In what year did statewide regulation of OSSF begin?

Statewide regulation of On-Site Sewage Facilities (OSSF) began in 1989 in Texas. This was a significant development in environmental policy as it marked the establishment of a uniform system for managing sewage disposal to protect public health and the environment. Before this regulation, practices varied widely, leading to inconsistent management and potential health risks due to inadequate sewage disposal methods. The regulation aimed to standardize installation practices, enforce proper maintenance, and ensure that OSSF systems reliably performed as intended. This foundational change ultimately improved oversight and compliance in managing on-site sewage treatment systems across the state.
