WS – 1 <br /> <br />WORK SESSION STAFF REPORT <br />Work Session Item No. 1 <br /> <br /> <br />Date: July 6 , 2020 <br /> <br />To: City Council <br /> <br />From: Rick DeGardner, Public Services Director <br />Michael Grochala, Community Development Director <br /> <br />Re: Water Treatment Plant Feasibility Study <br /> <br />Background <br />The Minnesota Department of Health recently tested the City’s manganese levels in each of the <br />City’s wells as part of the EPA Unregulated Contaminant Monitoring Rule 4 (UCMR4). The <br />water quality testing data from MDH indicates that five of the City’s six wells exceed the <br />maximum recommended manganese level for infants, and three of the wells exceeds the <br />maximum recommend level for adults and children. <br />On March 9, 2020 the City Council authorized the preparation of a Water Treatment Plant <br />feasibility study to evaluate future water treatment options. The purpose of this feasibility study <br />was to evaluate alternative water supply options to address the high manganese levels in the <br />City’s drinking water to provide acceptable water quality that meets current and proposed <br />drinking water standards. WSB and Associates had prepared the study and Greg Johnson will <br />present the report at the City Council work session. <br />The study included an evaluation of: <br />1) Evaluation of Alternative Water Supply Options to address short to mid-term needs. <br />2) Analyze Source Water <br />3) Evaluate Water Treatment Options <br />4) Review Potential Plant Site <br />5) Prepare Centralized Water Treatment Plan Preliminary Drawings <br />6) Evaluate future system needs and phasing <br />7) Water Treatment Plant Impacts <br />8) Determine Estimated Costs <br />A conventional gravity filtration system that is modified to provide for biological filtration with <br />an initial treatment capacity of approximately 6,000 gpm is recommended for the City of Lino <br />Lakes. A water treatment pilot study should be conducted as the first step to verify the <br />effectiveness of the full scale treatment process for treating water to reduce manganese and iron. <br />The estimated cost of the water treatment plan was analyzed in the report.
