Lift Station #24 Wet Well Rehabilitation: Approve Quote
PW055XI
PROPOSED MOTION
"The City Council approves quote in the amount of $29,698.00 for the Lift
Station #24 Wet Well Rehabilitation to Infratech Technologies."
City Council approval requires a simple majority vote ofthe City Council
Lift Station #24, located at the intersection of Lyman Boulevard and Audubon Road, was
constructed in 1991. It is the largest of all the 31 lift stations and serves over 1,300 homes
and used to service a portion of the industrial park in Chaska.
Since its construction, the concrete wet wells have been subjected to Hydrogen Sulfide gas or
"sewer gas" that is commonly found in wastewater collection systems. This gas is highly
corrosive and has caused the concrete walls to spall or flake off.
This proposal is to provide a sprayed on, corrosion resistant, fiber reinforced coating to
protect the lift station's wet wells and ensure no further damage can be done to the concrete.
If left unprotected, major renovation may eventually be needed to repair the wet well walls in
the future.
Staff has obtain two quotes for this work as follows:
Infratec Technologies $29,698.00
Midwest Trenchless Technologies Inc. $59,627.00
The wide gap in the bids can be explained by work backlog by the contractors.
Infratec has completed past projects for the City. Their work has been acceptable.
Funding for the project is proposed from the annual sewer operations repair and maintenance
budget.
