Note:Increasesd 2013 amount to 500,000 because there will likely be another round of I&I elimination grants from MCES.Will not use addition dollars unless they can be leveraged for grant monies.5/21/12 TJM 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 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 for 20 years to reflect this cost. 10/1/12 TJM Justification 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 sewer infrastructure is aging,we should plan for a rehabilitation project on an annual basis.
