2009 Sanitary Sewer Rehabilitation (III) Project No. 09-03: Award
Construction Contract
PROPOSED MOTION
"The City Council awards a construction contract for the 2009 Sanitary Sewer
Rehabilitation (III) Project to Insituform Technologies USA, Inc. in the amount
of$175,837.40."
City Council approval requires a simple majority vote of the City Council
present.
DISCUSSION
The 2009 III project was designed to eliminate areas in the sanitary sewer system that
allows groundwater or surface water to enter. These improvements include lining
sewer pipes, pipe joint sealing, grouting manholes and pipe joints. Repairs to the
sewer pipes are scheduled to take place between the Chanhassen High School and
Lift Station #24. This section of concrete sanitary pipe has been damaged due to the
hydrogen sulfide released as the sewer flows through the pipe. The damage has
caused the rubber gasket seals at most joints to become loose which has allowed
ground water to drain into the pipe.
Staff feels this area contributes some of the highest levels of III to the system.
Attached is a map showing the repair areas proposed for 2009.
The proposed budget for the project was $190,000.00. In order to meet budget, staff
composed two alternates for the project. Alternate 1 included lining the section of
pipe Manhole 40-006 to Manhole 40-007. Alternate 2 involved installing short liners
north of the section of pipe to be lined. Due to the amount of funding allocated for
the 2009 project, staff feels that Alternate 2 can be removed from the project for this
year.

Project Name Inflow and Infiltration Abatement
Account #2
Description 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
.. City staff has identified numerous older sewer lines that are in need of repair. The City ofChanhassen 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 the annual charge if the City
was not actively trying to reduce the inflow and infiltration problem.

'Operational Impact/Other I
!he 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
[or those costs. It is the city's belief that as new customers come on line those connection fees should help fund future infiltration problems.
