Relating to water losses reported by certain municipally owned utilities to the Texas Water Development Board; authorizing administrative penalties.

SB 1190 requires large municipally owned water utilities (those serving over 150,000 connections) to validate their annual water loss reports within 180 days of filing and develop a water loss mitigation plan within one year. For utilities with three consecutive years of high reported water loss, the bill mandates more detailed validation of leakage reduction strategies and billing data, plus updated mitigation plans. The mitigation plans must include specific 1-year, 3-year, 5-year, and 10-year goals, project descriptions, and estimated financial and water savings. All plans must be integrated into the utility’s existing water conservation plan and reported annually. The bill authorizes administrative penalties for noncompliance but does not specify penalty amounts.
