City of Ramsey Local Water Supply Plan <br />Is the ratio of average 2005-2014 maximum day demand to average 2005-2014 average day <br />demand reported in Table 2 more than 2.6? Yes ❑x No ❑ <br />Calculate a ten year average (2005 — 2014) of the ratio of maximum day demand to average <br />day demand: 2.74 <br />The position of the DNR has been that a peak day/average day ratio that is above 2.6 for in <br />summer indicates that the water being used for irrigation by the residents in a community is <br />too large and that efforts should be made to reduce the peak day use by the community. <br />It should be noted that by reducing the peak day use, communities can also reduce the amount <br />of infrastructure that is required to meet the peak day use. This infrastructure includes new <br />wells, new 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 />Water Conservation Program <br />Municipal water suppliers serving over 1,000 people are required to adopt demand reduction <br />measures that include a conservation rate structure, or a uniform rate structure with a <br />conservation program that achieves demand reduction. These measures must achieve demand <br />reduction in ways that reduce water demand, water losses, peak water demands, and <br />nonessential water uses. These measures must be approved before a community may request <br />well construction approval from the Department of Health or before requesting an increase in <br />water appropriations permit volume (Minnesota Statutes, section 103G.291, subd. 3 and 4). <br />Rates should be adjusted on a regular basis to ensure that revenue of the system is adequate <br />under reduced demand scenarios. If a municipal water supplier intends to use a Uniform Rate <br />Structure, a community -wide Water Conservation Program that will achieve demand reduction <br />must be provided. <br />Current Water Rates <br />Include a copy of the actual rate structure in Appendix 9 or list current water rates including <br />base/service fees and volume charges below. <br />Volume included in base rate or service charge: 15,000 gallons or cubic feet other <br />Frequency of billing: ❑ Monthly ❑ Bimonthly ❑x Quarterly ❑ Other: <br />Water Rate Evaluation Frequency: ❑x every year ❑ every years ❑ no schedule <br />Date of last rate change: 1/1/2017 <br />43 April 7, 2017 <br />
