CC Regular Session 7. 4. Meeting Date: 01/23/2018 By: Bruce Westby, Engineering/Public Works Information Title Adopt Resolution #18-029 Approving Participation in Metropolitan Council Water Efficiency Potential Project Purpose/Background: Purpose: The purpose of this case is to adopt Resolution #18-029 approving the City of Ramsey's participation in the Metropolitan Council Water Efficiency Potential Project. Background: Per the attached email from the Metropolitan Council received November 27, 2017, a Water Efficiency Potential Project has been commissioned to assess the economic potential of whether an aggressive water conservation program could reduce a community's expansion of water supply to meet future residential needs. Based on current water use data and projected population growth, Ramsey ranks #19 out of all Twin Cities metro cities as a potential candidate community for economic analysis of potential peak water demand reduction. The Metropolitan Council therefore believes the City of Ramsey can potentially benefit from such an analysis, and would like to know if the City is willing to be included in the study. The study generally seeks to answer three questions regarding residential water use: 1. What overall peak reduction would a community need to achieve to avoid (or delay) installation of a new well? 2. What amount of total water savings could be realized, and how many years of delay for a new well (or wells) can be achieved? 3. What is the total cost to reduce peak demand through residential efficiency, and how does this cost compare with the cost of a new well (or wells)? The first step in the analysis was an exercise to determine which of the 94 metropolitan communities with groundwater supplies and a large residential sector have the most potential to benefit from this analysis. The Metropolitan Council considered total population growth through 2040, residential water demand, peak summer to winter ratio, and estimated number of new wells through 2040. Based on these factors, Ramsey ranks #19 (just breaking the top 20) of the 94 communities reviewed. See page 6 of the attached memo from CDM Smith, Met Council's consultant on this project, which details the analysis used to identify the communities with the greatest potential for residential water efficiency. There is no cost to participate in the study, but if a City agrees to participate the City must provide the following specific information for the next part of the analysis: • Well yield data for each well • Annual operational costs for treatment and for well operation • Description, program costs, and number of staff for current water conservation programs • Unit cost per 1,000 gallons of raw water (before treatment, if any) This information can be generated by Staff within several hours if Council approves participation in the project. The Metropolitan Council originally requested a response by December 8, 2017 as to whether the City of Ramsey
