to proactive leakage management, allowing them to substantially
reduce leakage losses in an efficient and economical manner.
Project #4372b, Water Audits in the United States: A Review of
Water Losses and Data Validity (Sturm et al. 2015), assessed the
adoption of American Water Works Association (AWWA) water
audit methodology and evaluated the levels of distribution-
system water loss occurring in five regions. To this end, the
research team investigated the reporting frameworks of regions
that track water loss and collected AWWA-methodology audits
from the California Urban Water Conservation Council (CUWCC),
the Delaware River Basin Commission (DRBC), the Georgia
Nevertheless, the vast majority of North American water utili-
ties only employ a reactive leakage management strategy, repair-
ing reported failures in a more or less timely manner. With a few
exceptions, North American water utilities are under little or no
regulatory pressure to efficiently control leaks.
As a result, water utilities continue to see increased leaks due
to a rising backlog of unreported failures in their distribution
systems. This is in spite of the fact that industry research and
case studies have demonstrated the benefits of proactive leakage management. The drinking water industry stands to benefit
greatly in transitioning from purely reactive leakage management
Audit Data Validity
Water utilities, regulatory agencies, and a variety of stakeholders have recently increased their focus on water efficiency due to continuing droughts, the increas- ing cost of providing potable water to customers, potential health risks posed by leaking pipes, and heightened awareness of the increasing cost of leakage.
