respectively. Today, low-flow showerhead saturation is estimated to be more than 90% in<br />
single- and multi-family homes. As a result, water agencies throughout <strong>Orange</strong> <strong>County</strong><br />
have achieved the 75% saturation requirement for this BMP. No further low-flow<br />
showerhead distribution or installation activity has occurred.<br />
4.2.3. DMM 3: System <strong>Water</strong> Audits, Leak Detection and Repair<br />
With the sale <strong>of</strong> the Allen-McColloch Pipeline to Metropolitan in 1995, MWDOC no<br />
longer owns or operates a distribution system. <strong>Water</strong> purchased and sold by MWDOC is<br />
distributed through Metropolitan’s system to the MWDOC retail agencies. As a result,<br />
implementation <strong>of</strong> BMP No. 3 is not applicable to MWDOC.<br />
However, in an effort to assist its retail agencies, MWDOC publishes annually the<br />
<strong>Orange</strong> <strong>County</strong> <strong>Water</strong> Agencies <strong>Water</strong> Rates, <strong>Water</strong> System Operations, and Financial<br />
Information survey. This survey facilitates a pre-screening survey that estimates the<br />
volume and percent <strong>of</strong> unaccounted-for-water for each retail water agency in the county.<br />
In 2009, the percent <strong>of</strong> unaccounted-for-water for retail water agencies ranged from a low<br />
<strong>of</strong> 1.5% to a high <strong>of</strong> 7.5%, with an average <strong>of</strong> 3.8%<br />
In addition to the survey, MWDOC was awarded a grant to implement a study titled<br />
“<strong>Water</strong> Loss Management Program Assessment: Potable <strong>Water</strong> System Audits.” This<br />
study used the American <strong>Water</strong> Works Association and International <strong>Water</strong> Association<br />
<strong>Water</strong> Audit Methodology. The following retail water agencies participated in the study:<br />
City <strong>of</strong> Brea, City <strong>of</strong> Huntington Beach, Laguna Beach <strong>County</strong> <strong>Water</strong> <strong>District</strong>, Moulton<br />
Niguel <strong>Water</strong> <strong>District</strong> and City <strong>of</strong> Tustin.<br />
The purpose <strong>of</strong> the study was to:<br />
• Educate the agencies on the most current water loss control methods and<br />
technologies<br />
• Perform system water audit for each agency to determine current water losses and<br />
areas for improvement<br />
• Review each agency’s leakage management program and recommend<br />
improvements<br />
• Assist the agencies in achieving the California Urban <strong>Water</strong> Conservation Council<br />
Best Management Practice 1.2 compliance<br />
Non-Revenue water ranged from 3 to 10 percent <strong>of</strong> volume <strong>of</strong> water supplied, which is<br />
very good and will within the range <strong>of</strong> efficient water utilities concerned about<br />
conservation and water loss management practices.<br />
