Capital Improvement Plan <br />City of Arden Hills, Minnesota Contact Public Works Director <br />2018 2022thru Department Sanitary Sewer Department <br /> Description <br />Sewer Lining and Rehabilitation. <br />Note: An analysis of our system shows that we still have approximately 18 miles (40%) that are old clay lines subject to infiltration and root <br />intrusion. It was estimated it would cost $3,500,000 to line all of these clay lines over the next 20 years. Estimated expenditures have been extended <br />for 20 years to reflect this cost. <br />Project #09-Sew-002 <br />Priority 3 Important <br /> Justification <br />As part of our sanitary sewer program, lines found with holes and cracks allowing for infiltration should be lined or repaired as needed. As the <br />sewer infrastructure is aging, we should plan for a rehabilitation project on an annual basis. <br />2016 estimates show a remaining need of 1.6 to 2.2 million. Set a funding level of $400K every 2 years. <br />$200K has been moved into 2018 for anticipated projects, which will be eligible for the Met Council Grant durind the current grant period. <br /> Budget Impact/Other <br />This project will help the overall I&I reduction program. Savings are estimated at this time based on part of the surcharge fees for I&I by the <br />Metropolitan Council. <br />Useful Life 30 <br />Project Name Sewer Lining/Rehabilitation Category Sanitary Sewer Maintenance <br />Type Maintenance <br />TCAAP No <br />Total Project Cost:$1,000,000 <br />Total20182019202020212022Expenditures <br />1,000,000200,000 400,000 400,000Construction/Maintenance <br />200,000 400,000 400,000 1,000,000Total <br />Total20182019202020212022Funding Sources <br />1,000,000200,000 400,000 400,000Sanitary Sewer Utility Fund <br />200,000 400,000 400,000 1,000,000Total <br />Wednesday, September 13, 2017Page 14Produced Using the Plan-It Capital Planning Software
