PART IIL WATER CONSERVATION PLAN Water conservation programs are intended to reduce demand for water, improve the efficiency in use and reduce losses and waste of water. Long-term conservation measures that improve overall water use efficiencies can help reduce the need for short-term conservation measures. Water conservation is an important part of water resource management and can also help utility managers satisfy the ever-increasing demands being placed on water resources. Minnesota Statutes 103G.291, requires public water suppliers to implement demand reduction measures before seeking approvals to construct new wells ar increases in authorized volumes of water. Minnesota Rules 6115.0770, require water users to employ the best available means and practices to promote the efficient use of water. Conservation programs can be cost effective when compared to the generally higher costs of developing new sources of supply or expanding water and/or wastewater treatment plant capacities. A. Conservation Goals. The following section establishes goals for various measures of water demand. The programs necessary to achieve the goals will be described in the following section. Unaccounted Water calculate five ear avera es with data from Table 1 Average annual volume unaccounted water for the last 5 years 42,500,000 allons Avera e ercent unaccounted water for the last 5 ears 2.17% ercent AWWA recommends that unaccounted water not exceed 10%. Describe goals to reduce unaccounted water if the avera e of the last 5 ears exceeds 10%. Residential Gallons Per Ca ita Demand GPCD Average residential GPCD use for the last 5 years (use data from Table 42.5 GPCD 1 In 2002, average residential GPCD use in the Twin Cities Metropolitan Area was 75 GPCD. Describe oals to reduce residential demand if the avera e for the last 5 ears exceeds 75 GPCD. Total Per Capita Demand: From Table 1, is the trend in overall per capita demand over the past 10 years ❑ increasing or ❑ decreasing? If total GPCD is increasing, describe the goals to lower overall per capita demand or explain the reasons for the increase. The TPCD is staying about the same for the past 8 years for which we have data. Peak Demands calculate avera e ratio for last five ears usin data from Table 1 Avera e maximum da to avera e da ratio 2.66/1 If eak demands exceed a ratio of 2.6, describe the oals for lowerin eak demands. lr-Water supply�lan2 template[1] 16
