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