§ 5.3. Determination and control of unaccounted-for water.

Based on available data, the amount of unaccounted-for water during the past five (5) years has averaged less than ten (10) percent (see Appendix B). This is considered a reasonable level of unaccounted-for water and indicates that the city does not currently experience a major problem in water source metering, customer metering, or distribution system losses.

In the future, the city intends to continue to maintain the unaccounted water at a level below ten (10) percent. The city collects all data needed to make annual comparisons between the amount of water discharged to the distribution system and the volume of metered water sales. If the amount of unaccounted-for water significantly increases in the future, the city is prepared to take appropriate actions. The actions could include an accelerated meter replacement/repair program, recalibration of the meters which measure the amount of water discharged to the distribution system, expansion of the leak detection program, an upgraded flushing program and/or a comprehensive water audit to help determine the causes of increased unaccounted-for water.
