New WRF Research Develops Tool to Help Utilities Fight Leakage Losses

WRF project will help water utilities control leakage lossesDENVER, CO, November 26, 2014 – The Water Research Foundation, a leading sponsor of research supporting the water community, is helping water utilities better understand and control leakage in a cost-effective manner through recently completed research and the development of a new leakage analysis tool. Water Audits and Real Loss Component Analysis project (#4372) provides water utilities information to better understand the sources of their losses from leakage throughout the water distribution system and a tool to help analyze the economic impact of various intervention strategies.

The vast majority of water utilities in North America employ reactive leakage management strategies, through which failures are repaired when they are reported to the utility. Because of this, utilities are continuing to experience increases in leakage losses throughout the distribution system due to a rising backlog of unreported distribution system failures. These losses continue to mount in spite of the fact that significant industry research has emonstrated the economic and efficiency gains that can be achieved through proactive leakage management.

In order to develop an effective and proactive leakage loss reduction strategy, utilities must undertake three major steps: a “top-down” water audit; component analysis of real losses; and evaluation of leastcost real loss reduction strategies. The water audit estimates revenue and non-revenue water, as well as real losses as a sub-category of non-revenue water. The leakage component analysis further determines the known real losses and categorizes them into three types of leakage: reported, unreported, or background. This step includes water audit results, utility data on specific leak occurrences, and a calculation of background losses. By then combining the component analysis with an evaluation of least cost real loss reduction strategies, it is possible to calculate how much of each type of leakage can be economically reduced through the right combination of intervention tools. Very few water utilities have the necessary expertise in leakage loss management to efficiently undertake a leakage component
analysis and design the correct leakage control program. Water Research Foundation project #4372 was designed to fill this gap.

“This important research will help utilities better handle leakage issues they are facing, resulting in economic savings and more efficient utilization of valuable and finite water resources,” said Rob Renner, executive director of the Water Research Foundation. “The Water Research Foundation will continue to work to help our utility partners to provide safe water in the most economically efficient ways possible.”

The Water Research Foundation and the U.S. Environmental Protection Agency sponsored this research project that involved 10 utilities of various sizes from throughout North America. The full report and Component Analysis Model can be accessed through the WRF Website. A recently conducted Webcast on the project is also available on demand. Lastly, this project is featured in the latest edition of Water Research Foundation’s magazine, Advances in Water Research.
