Relating to the installation of a treatment system by certain public drinking water supply systems.
Summary
SB 2497 authorizes the Texas Commission on Environmental Quality, by order, to require certain small public drinking water supply systems to install a treatment system, including a filtration system, for an underground water source. The bill applies only to systems serving fewer than 100 connections and is aimed at systems that have repeatedly exceeded state water quality standards or have generated more than one substantiated water quality complaint in the prior 12 months, where the commission has determined that additional treatment is needed.
The bill also limits this authority to situations where the treatment system can be installed at a reasonable cost and where the system is intended to address an exceedance of a secondary constituent level, if applicable. The measure takes effect September 1, 2025, and would amend Chapter 341 of the Health and Safety Code by adding a new section governing treatment requirements for certain underground sources.
Impact
SB 2497 would expand TCEQ’s enforcement and corrective-action authority over small public water systems that rely on underground sources, allowing the agency to compel installation of treatment infrastructure in specified cases. It would affect public drinking water supply systems with fewer than 100 connections, particularly in rural or small-community settings, and could require capital investment in filtration or other treatment technologies to address recurring contamination or quality complaints. The bill would amend the Health and Safety Code and create a new statutory basis for agency-ordered treatment measures.
Sentiment
The available voting history suggests the bill had generally favorable support in the Senate, passing on a 26-5 vote after suspension of the rules and the three-day rule. No committee transcript is available, but the narrow number of dissenting votes indicates some concern remained, likely around regulatory burden, cost, or the scope of agency authority. Overall, the bill appears to have been treated as a targeted water-quality measure rather than a broad policy overhaul.
Contention
The main points of potential contention are the mandate on small water systems, the cost of installing treatment equipment, and the discretion given to the commission to order such systems. Opponents may be concerned that small or rural providers could face financial strain or operational challenges, while supporters likely view the bill as a necessary tool to protect public health where repeated water-quality problems persist. The bill’s reasonable-cost limitation suggests an attempt to balance enforcement with feasibility, but that standard could itself be a point of dispute.
