d) They will also discuss options for improvement and/or collect case studies of success stories to share <br /> with other communities. One option may be to change the rate structure, but there are many other <br /> paths to successful water conservation. <br /> e) If appropriate,they will cooperatively develop a simple work plan for the next few years,targeting a <br /> couple areas where the city might focus efforts. <br /> A. Regulation <br /> Complete Table 29 by selecting which regulations are used to reduce demand and improve water <br /> efficiencies. Add additional rows as needed. <br /> Copies of adopted regulations or proposed restrictions or should be included in Appendix 10(a list with <br /> hyperlinks is acceptable). <br /> Table 29.Regulations for short-term reductions in demand and long-term improvements in water efficiencies <br /> a , <br /> eta <br /> ✓ Rainfall sensors required on landscape irrigation systems V Ongoing <br /> ✓ Critical/Emergency Water Deficiency ordinance ❑Only during declared Emergencies <br /> ✓ Watering restriction requirements(time of day,allowable days, V Odd/Even <br /> etc.) <br /> ✓ Soil preparation requirement s(after construction, requiring topsoil V New Development <br /> to be applied to promote good root growth) V Construction Projects <br /> ✓ Tree ratios(requiring a certain number of trees per square foot of V New development <br /> lawn) <br /> B. Retrofitting Programs <br /> Education and incentive programs aimed at replacing inefficient plumbing fixtures and appliances can <br /> help reduce per capita water use, as well as energy costs. It is recommended that municipal water <br /> suppliers develop a long-term plan to retrofit public buildings with water efficient plumbing fixtures and <br /> appliances. Some water suppliers have developed partnerships with organizations having similar <br /> conservation goals, such as electric or gas suppliers,to develop cooperative rebate and retrofit <br /> programs. <br /> A study by the AWWA Research Foundation (Residential End Uses of Water, 1999)found that the <br /> average indoor water use for a non-conserving home is 69.3 gallons per capita per day (gpcd).The <br /> average indoor water use in a conserving home is 45.2 gpcd and most of the decrease in water use is <br /> related to water efficient plumbing fixtures and appliances that can reduce water, sewer and energy <br /> costs. In Minnesota, certain electric and gas providers are required (Minnesota Statute 2166.241)to <br /> fund programs that will conserve energy resources and some utilities have distributed water efficient <br /> showerheads to customers to help reduce energy demands required to supply hot water. <br /> Retrofitting Programs <br /> Complete Table 30 by checking which water uses are targeted,the outreach methods used,the <br /> measures used to identify success, and any participating partners. <br /> 40 <br /> 80 <br />
