Metering. The American Water Works Association (AWWA) recommends that every <br />water utility meter all water taken into its system and all water distributed from its system <br />at its customer's point of service. An effective metering program relies upon periodic <br />performance testing, repair, repair and maintenance of all meters. AWWA also <br />recommends that utilities conduct regular water audits to ensure accountability. <br />Complete Table 10 (A) regarding the number and maintenance of customer meters. <br />TABLE 10 (A' Customer Meters <br />Number of <br />Number of <br />Meter testing <br />Average age /meter <br />Connections <br />Metered <br />schedule (years) <br />replacement schedule <br />Connections <br />(years) <br />Residential <br />888 <br />888 <br />15 <br />10 /25 <br />Institutional <br />/ <br />Commercial <br />36 <br />36 <br />10 <br />10 /25 <br />Industrial <br />10 /25 <br />Public <br />3 <br />3 <br />15 <br />10 /25 <br />Facilities <br />Other <br />8 <br />8 <br />10 <br />10 /25 <br />TOTALS <br />935 <br />935 <br />Unmetered Systems.

Unaccounted Water. Water audits are intended to identify, quantify, and verify water <br />and revenue losses. The volume of unaccounted -for water should be evaluated each billing <br />cycle. The AWWA recommends a goal of ten percent or less for unaccounted -for water. <br />Water audit procedures are available from the AWWA and MN Rural Water Association. <br />Frequency of water audits: ❑ each billing cycle ® yearly ❑ other: <br />Leak detection and survey: El every year ❑ every years ® periodic as needed <br />Year last leak detection survey completed: <br />Reducing Unaccounted Water. List potential sources and efforts being taken to reduce <br />unaccounted water. If unaccounted water exceeds 10% of total withdrawals, include the <br />timeframe for completing work to reduce unaccounted water to 10% or less. <br />Page 13 of 19 <br />M <br />
