Currently, all retail public water systems with more than 3,300 connections or a financial obligation to TWDB are required to complete and submit a Water Loss Audit annually. All other retail public water suppliers are required to submit a Water Loss Audit to the agency every five years. The next five-year deadline to submit an audit is for the 2025 reporting year, due by May 1st, 2026.

Water Loss Use and Conservation (WLUC) Workshops

The Texas Water Development Board (TWDB) will be conducting training based on the water use survey, water loss audit, and water conservation reports. Information on TWDB’s financial assistance and Texas Commission on Environmental Quality’s financial, management, and technical assistance programs will be included.

The WLUC workshops, part of TWDB’s Technical Assistance for Water Loss Control program (TAWLC), looks at water loss from a water stewardship perspective. Public utility revenue loss, collecting and reporting accurate data, assessing, auditing, and data validation will be reviewed. Data validation is accomplished using TWDB’s assessment scales which help utilities identify action items for water loss control.

The WLUC workshops are provided at no cost to participants and approved for 4 hours of continuing education for licensed water operators through the Texas Commission on Environmental Quality.

Attendance at these workshops satisfies the legislative requirement under 31 Texas Administrative Code (TAC) § 358.6 (b)(4), requiring water loss auditor training prior to submitting a water loss audit to TWDB. The training requirement can also be satisfied by viewing a pre-recorded training video.
