<br />DRAFT <br /> <br />PART III. WATER CONSERVATION PLAN <br /> <br />Water conservation programs are intended to reduce demand for water, improve the efficiency in <br />use and reduce losses and waste of water. Long-term conservation measures that improve overall <br />water use efficiencies can help reduce the need for shon-term conservation measures. Water <br />conservation is an imponant pan of water resource management and can also help utility <br />managers satisfy the ever-increasing demands being placed on water resources. <br /> <br />Minnesota Statutes I 03G.291, requires public water suppliers to implement demand reduction measures before <br />seeking approvals to construct new wells or increases in authorized volumes of water. Minnesola Rules 6115.0770, <br />require wllter users to employ the best available means and practices to promote the effiCient use of water. <br />Conservation programs can be cost effective when compared 10 the generally higher costs of developing new sources <br />of supplv or expanding water and/or wastewater treatment plant capacilies. <br /> <br />A. Conservation Goals. The following section establishes goals for various measures of water <br />demand. The programs necessary to achieve the goals will be described in the following <br />section. <br /> <br />Unaccounted Water calculate five ear avera es with data from Table I) <br />Average annual volume unaccounted water for the last 5 years 3,758,000 <br />allons <br />Avera e ercent unaccounted water for the last 5 ears 4.3 ercent <br />A WW A recommends that unaccounted water not exceed 10%. Describe goals to reduce <br />unaccounted water ifthe avera e of the last 5 ears exceeds 10%. <br />N/A <br /> <br />Residential Gallons Per Ca ita Demand GPCD <br />Avera e residential GPCD use for the last 5 ears use data from Table I) 94.6 GPCD <br />In 2002, average residential GPCD use in the Twin Cities Metropolitan Area was 75 GPCD. <br />Describe oals to reduce residential demand ifthe avera e for the last 5 ears exceeds 75 GPCD. <br />City will consider requirement for rain sensors on irrigation, will evaluate rate system to determine <br />if increasing block structure may be appropriate and considering monthly billing. <br /> <br />Total Per Capita Demand: From Table I, is the trend in overall per capita demand over the past <br />10 years cgj increasing or D decreasing? If total GPCD is increasing, describe the goals to lower <br />overall per capita demand or explain the reasons for the increase. <br />Will consider requirement for rain sensors on irrigation, will evaluate rate system to determine if <br />increasing block structure may be appropriate, considering monthly billing and increasing tree <br />planting requirements.. <br /> <br />O:\Planning Commission\Comp Plan UpdakWatcr Conservation Plnn\2U07 Wak'T conservation v4.doc <br />13 <br />
