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

HB 29 requires large municipally owned water utilities (those serving over 150,000 connections) to verify their annual water loss reports through independent validation within 180 days of filing. It mandates these utilities to develop and submit a water loss mitigation plan within one year, updated every 10 years with detailed goals and projects. The bill also requires these plans to be integrated into existing water conservation reporting and includes specific guidelines for certified validation personnel. This law directly affects major municipal water providers across Texas, focusing on improving accuracy in water loss reporting and reducing waste through structured planning.
