This paper discusses the need for improved
performance in the area of water loss control and reduction of unwanted demand, and how this need requires improved and standardized methods of performance base lining and target setting. The most recent AWWA Water Loss Control Committee report (approved in December
of 2002) now fully endorses the use of the new performance indicators. It discusses the international data set and the North American data set and recommends two AWWARF projects, #s 2811 and 2928, which are directly related to the improvement and
standardization of water loss performance reporting and management.
Both of these research projects have been designed to adopt internationally recognized
best practice and adapt it for use in North America.
The overall goal of project 2811 is to prepare a comprehensive guidance document which
can be used by water utilities to:
select appropriate performance indicators;
prepare an accurate water audit and (and water balance);
determine the economic level of leakage; and,
plan and implement water loss reduction programs. The overall goal of project 2928 is to provide North American utilities with tools and
guidelines to proactively manage and reduce water loss due to leaks in the distribution
system.
This will be accomplished using an in-depth five-step approach that includes:
a detailed review of United Kingdom, International, and North
American current best practice;
a detailed analysis of those methodologies that are applicable
and transferable to the North American reality, and the development of a
new model to include necessary changes required for safe and sustainable
leakage management tailored to North America; a review of the
applicability of using United Kingdom and International methods to determine the
economic level of leakage (ELL);
hands-on testing of promising methodologies within the
participating utilities water distribution systems; and, the development of the final water leakage management tools
and guidelines. Includes 7 references, tables, figures.
