Local Water Supply Plan Template –December 8, 2015 <br /> <br />34 <br /> <br />Strategy to reduce total business, industry, agricultural demand Timeframe for completing work <br />residential customers when water availability conditions <br />change. <br />[Rainwater catchment systems intended to supply uses <br />such as water closets, urinals, trap primers for floor drains <br />and floor sinks, industrial processes, water features, vehicle <br />washing facilities, cooling tower makeup, and similar uses <br />shall be approved by the commissioner. Proposed plumbing <br />code 4714.1702.1 <br />http://www.dli.mn.gov/PDF/docket/4714rule.pdf <br /> <br />Describe other plans: City has participated in the <br />Regional Indicators Initiative (RII) in order to track water <br />usage by customer category <br />Ongoing <br />Objective 4: Achieve a Decreasing Trend in Total Per Capita Demand <br />Include as Appendix 8 one graph showing total per capita water demand for each customer category <br />(i.e., residential, institutional, commercial, industrial) from 2005-2014 and add the calculated/estimated <br />linear trend for the next 10 years. <br />Describe the trend for each customer category; explain the reason(s) for the trends, and where trends <br />are increasing. <br />Each customer category shows a decreasing water use trend. The decrease in water usage can be attributed to <br />implementing the water reuse facility, water efficient fixtures, and public education on the importance of water <br />conservation. <br />Objective 5: Reduce Peak Day Demand so that the Ratio of Average Maximum day to the <br />Average Day is less than 2.6 <br />Is the ratio of average 2005-2014 maximum day demand to average 2005-2014 average day demand <br />reported in Table 2 more than 2.6?  Yes  No <br />Calculate a ten year average (2005 – 2014) of the ratio of maximum day demand to average day <br />demand: _2.3_ <br />The position of the DNR has been that a peak day/average day ratio that is above 2.6 for in summer <br />indicates that the water being used for irrigation by the residents in a community is too large and that <br />efforts should be made to reduce the peak day use by the community. <br /> <br />It should be noted that by reducing the peak day use, communities can also reduce the amount of <br />infrastructure that is required to meet the peak day use. This infrastructure includes new wells, new <br />water towers which can be costly items. <br />Objective 6: Implement a Conservation Water Rate Structure and/or a Uniform Rate <br />Structure with a Water Conservation Program <br /> <br /> <br />
