PART III. 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 or 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 year averages with data from Table 1 Average residential GPCD use for the last 5 years use data from Table 1) : 86 GPCD Average annual volume unaccounted water for the last 5 years 11,780,000 gallons Average percent unaccounted water for the last 5 years 2.4 percent AWWA recommends that unaccounted water not exceed 10 %. Describe goals to reduce unaccounted water if the average of the last 5 years exceeds 10 %. The City's unaccounted water falls below the recommended 10% unaccounted water. Residential Gallons Per Capita Demand (GPCD) Average residential GPCD use for the last 5 years use data from Table 1) : 86 GPCD In 2002, average residential GPCD use in the Twin Metropolitan Area was 75 GPCD. Describe goals to reduce residential demand if the average for the last 5 years exceeds 75 GPCD. Phase 1 1. Prepare an ordinance requiring rain sensors to be installed with all automatic sprinkler systems. 2. Provide public education to consumers regarding information on how to reduce water usage indoors and outdoors. 50% of water consumed by a household is used outdoors. The remaining 50% is used indoors and of that 75% is consumed in the bathroom. a. Water conservation section in the Lino Lakes Newsletter and at www.ci.lino- lakes.mn.us, providing tips and information on water conservation. b. Monthly or bi- monthly billing encourages conservation by providing timely information on water usage which gives customers an opportunity to make modifications in water use practices or identify and repair costly leaks. Attachments and flyers with water bills can also be used to provide information on how to use water efficiently. Phase 2 1. Consumer surveys, feedback, and contact with high volume consumers. a. Contact consumers with high volumes of usage to provide conservation tips and potential cost saving ideas. b. Prepare a household water audit kit, which gathers consumer feedback on conservation 13
