Local Water Supply Plan Template —March 2016 ❑ 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.dii.mn.gov/PDF/docket/4714rule.j?df ❑ 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; and where trends are increasing. Objective 5: Reduce Peak Day Demand so that the Ratio of Average Maximum day to the Average Day is less than 2.6 ❑ Yes ❑ No Calculate a ten year average (2005 — 2014) of the ratio of maximum day demand to average day demand: 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. It should be noted that by reducing the peak day use, communities can also reduce the amount of infrastructure that is required to meet the peak day use. This infrastructure includes new wells, new water towers which can be costly items. Objective 6: Implement a Conservation Water Rate Structure and/or a Uniform Rate Structure with a Water Conservation Program 32 66
