Mill Ditch Sewer Replacement Project Update Details: The Mill Ditch Sewer Main is in disrepair and is undersized for the overall anticipated growth in the North Shore area. The City's National Pollution Discharge Elimination System (NPDES) Sewer Permit requires the City to spend a minimum of $250,000 in inflow and infiltration improvements to the sewer system in both 2017 and 2018. Replacement of the Mill Ditch Sewer Main helps the City to meet this requirement. $450,000 was allocated to this inflow and infiltration related improvement in the 2017 Budget. Due to unforeseen difficulties in construction, the cost to replace all of the sewer main in the awarded bid will exceed the budgeted amount for this project. Staff provided an explanation and recommended scoping change to Council. Presenter: James Carothers, Engineering Manager
