<br /> <br />Lino Lakes Main Street - AUAR 42 August 2025 <br />Table 8: Projected Wastewater Demands <br />Wastewater Demands Scenario 1 Average Daily <br />Flow (GPD) <br />Scenario 2 Average Daily <br />Flow (GPD) <br />Residential 493,200 548,000 <br />Commercial 8,800 9,100 <br />Total 502,000 557,100 <br /> <br />The City’s sanitary sewer collection system will be extended to serve the study <br />area through a combination of 1) gravity sewer extensions from the existing <br />sanitary sewer system, and 2) a new trunk sewer, lift station, and forcemain. All <br />proposed units will be required to connect to the City’s sanitary sewer system. <br />A new trunk line will need be extended from Met Council Interceptor 8361 located <br />on North Road to the northwest sanitary sewer service sub-district 2J. This is <br />outlined in the City’s 2040 Comprehensive Plan Figure 8-5 with a forcemain <br />along Sunset Avenue and a lift station north of Main Street. The area would be <br />served by 10-inch and 12-inch trunk lines along Main Street (see Figure 16 ). <br />The City’s sanitary sewer district 2 discharges to Metropolitan Council <br />Environmental Services (MCES) Meter M211 and Interceptor 8361, and MCES <br />will evaluate necessary improvements to their interceptor system. Wastewater is <br />then conveyed to the Metropolitan Wastewater Treatment Plant (Metro WWTP). <br />The Metro WWTP has a capacity of 314 million gallons per day (MGD) and <br />receives 180 MGD of flow as of June 2024. The Metro WWTP is expected to <br />have capacity to treat demand from both scenarios. The wastewater from the <br />study area is anticipated to be of typical domestic strength and character, so <br />pretreatment is not necessary. <br />Page 72 of 679
