During the water study and testing at Water Treatment Plant No. 1 the Minnesota <br />Department of Health (MDH) brought to the attention of AE2S and Mounds View Public <br />Works Staff, that WTP No. 1 had combined radium results above the regulated maximum <br />contaminant level (MCL). Due to this discovery Water Treatment Plant No. 1 was removed <br />from the current scope of bidding. It was determined that further testing and information as <br />well as completing a water pilot study would be needed, in order to provide the City Council <br />and residents the best options for safe drinking water at Water Treatment Plant No. 1. <br />AE2S has provided a proposal for completing a pilot study at Water Treatment Plant No. 1 <br />(WTP1). This study would coincide with the high water demand levels, during the summer <br />of 2020. After completion of the study and analyzing the results AE2S would make <br />recommendations on improvements at WTP 1. These improvements would not take place <br />until 2021 or 2022. AE2S provided a proposed cost for the study of $38,900.00. <br />AE2S has provided a technical memorandum (attached to this report) summarizing the <br />planned improvements, recommendations and estimated project costs of $6,594,137.00 for <br />the water treatment facilities rehabilitation and improvements. The following is a proposed <br />time line of WTP 1, 2 and the booster station: <br />1. City Council to authorize bid advertisement at the October 14th, 2019 Council <br />Meeting <br />2. Publish bid advertisement on October 30th, 2019 <br />3. Conduct bid opening on November 26th, 2019 at 2:00 PM <br />4. City Council to Award construction contract at December 9th, 2019 Council Meeting <br />Strategic Plan Strategy/Goal: Maintain and Plan for Infrastructure Improvements. Ensure <br />Clean Water and Maintenance. <br />Financial Impact: No financial Impact to the 2019 Budget. The 2019 Water Fund budgeted <br />estimate of $400,000 for Water Treatment Plant and Engineering Design. <br />Recommendation: <br />Public Works Staff recommends the City Council approve the attached resolution Authorizing <br />AE2S to complete the plans a specifications for the Water Treatment Plant Rehabilitation <br />Project. Staff also recommends the Council Approve the Council approve the Radium <br />Removal Pilot Study at Water Treatment Plant No. 1 as proposed by AE2S for $38,900. <br />Respectfully submitted, <br />Don Peterson, Public Works Director <br />The Mounds View Vision <br />A Thriving Desirable Community <br />
