Description Total Project Cost $825,000
I This annual project includes televising, repairs and rehabilitation of existing sanitary sewer. The program also detects and eliminates points of entry
of ground water and surface water into the City sanitary sewer system. Projects have been identified from the 2006 Inflow and Infiltration Report.
The projects were reviewed by Metropolitan Council and approved in lieu of surcharge fees.
I
Justification I
I City staff has identified numerous older sewer lines that are in need of repair. The City of Chanhassen pays the Metropolitan Council for sewage
treatment. Those payments are based on the amount of flow generated by the City of Chanhassen. Surface water and ground water that makes its
way into the system either through breaks, displaced joints, manhole covers, or private connections to the system increase the amount charged to
the City for sewage disposal and increasing the load on the City's lift stations. Also, MCES would place a surcharge on the annual charge if the
I City was not actively trying to reduce the inflow and infiltration problem.

Budget Impact/Other L
The efforts may decrease operational costs, MCES fees and emergency call outs. It is also the City's intent to use connection charges to help fund
for those costs. It is the City's belief that as new customers come on line those connection fees should help fund future infiltration problems.
