Texas

7,988 community water systems on record — 4,749 active, 3,239 inactive.

Every active community water system nationwide must produce a Consumer Confidence Report under the EPA's revised rule, effective for reports due July 1, 2027.

Data sourced from the EPA ECHO database (SDWA bulk download), last refreshed August 1, 2026. This is a record-keeping and public-information tool — it does not replace Texas’s official records. Always confirm current status with Texas before making decisions based on this information.
