Local Water Supply Plan Template –July 8, 2016 <br /> <br />31 <br /> <br />What is your leak detection monitoring schedule? (e.g. monitor 1/3rd of the city lines per year) <br />Periodic as needed. <br />Water Audits - are intended to identify, quantify and verify water and revenue losses. The volume of <br />unaccounted-for water should be evaluated each billing cycle. The American Water Works Association <br />(AWWA) recommends that ten percent or less of pumped water is unaccounted-for water. Water audit <br />procedures are available from the AWWA and MN Rural Water Association www.mrwa.com . Drinking <br />Water Revolving Loan Funds are available for purchase of new meters when new plants are built. <br />What is the date of your most recent water audit? _n/a___ <br />Frequency of water audits: ☐ yearly ☒ other (specify frequency) _periodic as needed__ <br />Leak detection and survey: ☐ every year ☐ every other year ☒ periodic as needed <br />Year last leak detection survey completed: ___n/a____ <br />If Table 2 shows annual water losses over 10% or an increasing trend over time, describe what actions <br />will be taken to reach the <10% loss objective and within what timeframe <br />City will consider metering water during hydrant flushing, flooding ice rinks, etc.. <br /> <br />Metering -AWWA recommends that every water supplier install meters to account for all water taken <br />into its system, along with all water distributed from its system at each customer’s point of service. An <br />effective metering program relies upon periodic performance testing, repair, maintenance or <br />replacement of all meters. AWWA also recommends that water suppliers conduct regular water audits <br />to ensure accountability. Some cities install separate meters for interior and exterior water use, but <br />some research suggests that this may not result in water conservation. <br />Complete Table 23 by adding the requested information regarding the number, types, testing and <br />maintenance of customer meters. <br />Table 23.
