Relating to the production by the Texas Commission on Environmental Quality of an annual report on public drinking water supply systems.

HB 157 requires the Texas Commission on Environmental Quality (TCEQ) to produce an annual report on all public drinking water supply systems in Texas by September 1 each year, starting in 2026. The report must include: (1) analysis of significant incidents affecting water systems and their consequences, (2) forecasts of system wear, tear, and population-driven performance impacts, and (3) recommendations to prevent service disruptions during disasters. This legislation directly affects the TCEQ, which must compile and deliver the report to the legislature annually. The bill establishes a formal mechanism for ongoing oversight of water system reliability without changing current water quality standards or regulations.
