Summary for the 2040 Comprehensive Sanitary Sewer Plan City of Lino Lakes, MN <br /> <br />Goals & Policies <br /> <br />The City of Lino Lakes continues to actively pursue its sanitary sewer system goal to, “Maintain the City’s residents <br />and businesses with an affordable and safe sanitary sewer system.” The following five policies support this goal: <br />1. Provide a low-maintenance, cost-effective sewer system that meets the long-term needs of the City's <br />residents and businesses. <br />2. Provide sanitary sewer service to undeveloped areas in a planned manner. <br />3. Provide for the capacity and extension of sanitary sewer to developed areas of the City currently served by <br />on-site systems. <br />4. Establish an on-site septic system inspection program to identify potential failing systems. <br />5. Where possible, direct public sanitary sewer improvements to areas identified as having failed on-site <br />systems. <br />Existing Sanitary Sewer System <br /> <br />The City of Lino Lakes owns and operates a local wastewater collection system; the regional collection and treatment <br />of wastewater is performed by the Metropolitan Council (MCES). The City’s sanitary sewer system has been divided <br />into three existing and two future sanitary sewer districts based on the regional facilities to which each district <br />ultimately discharges. The City’s existing sewer system and sewer districts are shown in the attached figures. The <br />City sanitary sewer system consists of gravity sewer lines ranging from 8-inch to 24-inch diameter, thirteen (13) <br />sanitary sewer lift stations, and the associated forcemain. The MCES regional collection system conveys the <br />wastewater to the Metropolitan Wastewater Treatment Plant located southeast of St. Paul. <br /> Wastewater Flow Projections <br /> <br />Currently, the City of Lino Lakes generates a total of 1.02 million gallons of wastewater on an average day across its <br />three existing sanitary sewer districts. MCES projects that the total average day wastewater flow generated in the <br />City will increase to 1.52 million gallons by the year 2040. This increase in wastewater flow, and the areas of likely <br />increase, must be considered when maintaining the existing system, and especially when planning and designing <br />future gravity mains and lift stations. <br /> <br />The existing wastewater flow and preliminary projected 2040 wastewater flow are listed below in millions of gallons <br />per day (MGD). The projected 2040 average flow listed below is significantly greater than the average flow projected <br />by MCES because this study considers each parcel of developable land to thoroughly plan future improvements. <br /> <br />Sanitary <br />Sewer <br />District <br />Existing <br />Average Flow <br />(MGD) <br />Existing Peak <br />Flow (MGD) <br />Preliminary <br />2040 Average <br />Flow (MGD) <br />Preliminary <br />2040 Peak Flow <br />(MGD) <br />1 0.42 2.09 0.71 2.35 <br />2 0.47 1.87 1.20 4.42 <br />3 0.13 0.63 0.70 2.62 <br />4 - - 0.13 0.52 <br />5 - - 0.28 1.03 <br />Total 1.02 4.59 3.02 10.94 <br /> <br />
