Local Water Supply Plan Template –July 8, 2016 34 Strategy to reduce total business, industry, agricultural demand Timeframe for completing work ☒ Install water conservation fixtures and appliances or change processes to conserve water Ongoing ☒ Repair leaking system components (e.g., pipes, valves) Ongoing ☒ Investigate the reuse of reclaimed water (e.g., stormwater, wastewater effluent, process wastewater, etc.) Ongoing ☒ Reduce outdoor water use (e.g., turf replacement/reduction, rain gardens, rain barrels, smart irrigation, outdoor water use meters, etc.) Ongoing ☒ Train employees how to conserve water Ongoing – include for new employee training ☐ Implement a notification system to inform non-residential customers when water availability conditions change. ☐ Rainwater catchment systems intended to supply uses such as water closets, urinals, trap primers for floor drains and floor sinks, industrial processes, water features, vehicle washing facilities, cooling tower makeup, and similar uses shall be approved by the commissioner. Proposed plumbing code 4714.1702.1 http://www.dli.mn.gov/PDF/docket/4714rule.pdf ☐ Describe other plans: Objective 4: Achieve a Decreasing Trend in Total Per Capita Demand Include as Appendix 8 one graph showing total per capita water demand for each customer category (i.e., residential, institutional, commercial, industrial) from 2005-2014 and add the calculated/estimated linear trend for the next 10 years. Describe the trend for each customer category; explain the reason(s) for the trends, and where trends are increasing. There is a decreasing trend in total per capita water demand, as well as decreasing trends for both the residential and the C/I/I customer categories. The decreasing trend has been most pronounced in the last five years, since 2012. Residential demand shows a slightly clearer decreasing trend, so conservation and education efforts that impact household water use, such as rebate programs for improved fixtures and appliances and ordinance governing water use for air conditioning, are likely the reason for this trend. Objective 5: Reduce Peak Day Demand so that the Ratio of Average Maximum day to the Average Day is less than 2.6 Is the ratio of average 2005-2014 maximum day demand to average 2005-2014 average day demand reported in Table 2 more than 2.6? Yes ☐ No ☐ Unknown ☒ Calculate a ten year average (2005 – 2014) of the ratio of maximum day demand to average day demand: _Unknown_ The position of the DNR has been that a peak day/average day ratio that is above 2.6 for in summer indicates that the water being used for irrigation by the residents in a community is too large and that efforts should be made to reduce the peak day use by the community.
