SB 2497 Texas Senate · 89th Legislature (2025)

Relating to the installation of a treatment system by certain public drinking water supply systems.

SB 2497 requires small public drinking water systems (serving fewer than 100 connections) that get water from underground sources to install filtration systems under specific conditions. It applies when a system repeatedly exceeds health-related contaminant limits, has multiple verified water quality complaints in a year, or needs to manage non-health-related water quality standards. The requirement only applies if the filtration system can be installed at a reasonable cost. This bill targets small rural or community water systems, not large municipal providers. It takes effect September 1, 2025.

MODERATE

The bill was reformatted from an introduced draft to an engrossed version with substantive policy changes. The most significant change is that the treatment system requirement now applies to public drinking water systems serving fewer than 100 connections, whereas the original draft did not specify this threshold. The conditions for requiring treatment systems were also modified to include repeated exceedance of contaminant levels and substantiated water quality complaints.

Scope change

The bill now specifically applies to public drinking water systems serving fewer than 100 connections, narrowing the scope of systems subject to mandatory treatment requirements.
