Water Loss Audit and Leak Detection Workshops
The Texas Water Development Board's Water Loss Audit and Leak Detection Workshops are available to retail public water suppliers across Texas. The workshops provide water suppliers the opportunity to learn about how water loss audits can help them implement effective water loss control programs, how to use TWDBs online data collection system to submit audits and how to successfully account for water use and loss. Also included in the workshop is a hands-on session working on a water loss audit and an introduction to TWDBs leak detection equipment loan program. The workshops are approved for 4 hours of continuing education credits for licensed water operators through the Texas Commission on Environmental Quality. Note: Workshop attendance also satisfies the legislative requirement under HB1573 requiring water loss auditor training prior to submittal of a water loss audit to the Texas Water Development Board.
The following workshops have been scheduled for Fall 2018.
Please contact Daniel Rice by phone at (512) 463-0987 or by email Daniel Rice to reserve a spot at your preferred location.
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 2020 reporting year, due May 1st, 2021.
A water supplier may request a workshop at any time, however, TWDB staff requires a minimum of 10 participants and a meeting place with appropriate facilities to support the workshop. The participants may come entirely from within the water supplier's organization or from other interested water suppliers.
