Scandia, MN 55073 (651) 433-2274
Action Requested: Approve plans and specifications and authorize advertisement for bids
for the Uptown Wastewater Treatment System improvement project.
Deadline/ Timeline: If plans are approved at the July 17 Council meeting, bids would be
opened on August 15, 20l 2 with a possible bid award at the August
21, 2012 City Council meeting.
Background: • In February, the Council approved an agreement with Bolton &
Menk for professional services for work need to implement the
2011 Uptown Wastewater System Master Plan. The first step,
which has been completed, was installation of run time meters in
the existing Community Center and Uptown pump tank control
panels, and replacement of the Warming House pump tank
controls.
• Since then, wastewater was been sampled and data was collected
from the run-time meters daily to obtain the information needed
for design of the equalization tank and aerobic pretreatment unit
and the new uptown pump tank. The plans are now complete and
ready for bidding.
• Brian Malm from Bolton & Menk will be present at the Council
meeting. The Wastewater Advisory Committee will also be
briefed at its July l9, 2012 meeting.
• The Uptown Master Plan estimated the cost of the equalization
tank and aerobic pretreatment unit to be $73,209. The new
uptown pump tank was estimated to cost $25,564.
Recommendation: Staff recommends approval of the plans and specifications and
advertisement for bids.
