SUBJ: Lift Station #3: Approve Quote for Replacement of Standby
Generator
PROPOSED MOTION
"The City Council approves a quote in the amount of $23,021.00 for a PSS90
90 Kw replacement standby generator from Winco, Inc. of Le Center, MN for
Lift Station #3."
City Council approval requires a simple majority vote of the City Council
present.
BACKGROUND
Lift Station #3 is located on the north side of Trunk Highway 7 just west of Church
Road at 3900 Highway 7. The station is the main collection point for wastewater in the
western portion of the city and is the fourth largest station the City owns and maintains.
Four smaller lift stations flow into Lift Station #3. The local power grid near Lift
Station #3 has had a long history of power outages and in 2008 a permanent standby
generator was placed there to provide automatic transfer of back -up power. The
stationary generator provided power to the lift station to avoid sanitary sewer
overflows but also frees up the Utility Department's mobile generators to supply
power to other lift stations in town during widespread outages. The standby generator
was decided to be fueled by natural gas since a trunk natural gas main is along
Highway 7 in close proximity to the station.
Staff is requesting approval to purchase a replacement generator for the mechanically
broken unit. During a scheduled maintenance test on February 6, 2014, the
generator's engine suffered a catastrophic failure involving natural gas getting past
the engine's cylinders, causing extensive internal damage. The estimate to repair the
engine is $28,714.50. Staff has learned this engine is prone to this type of failure and
a repair could recreate the conditions that allowed the original failure. The generator
has past the warranty period and the manufacturer has not recalled the unit to fix the
problem or has offered to help pay for replacement of the engine.

The general specification for the generator is as follows:
Eighty to ninety (80 -90) Kw natural gas stationary generator set mounted in a sound, attenuated
enclosure. This generator utilizes a 5.7 liter GM engine. This generator is not the same manufacture
as the failed unit.
Staff has received four quote options for the generator as follows:
Staff is proposing to defer maintenance on Lift Station 22 schedule for this year to pay for the
replacement generator at Lift Station #3 out of the lift station rehabilitation program budgeted funds.
Note: Since the generator has failed, a temporary generator receptacle has been installed at Lift
Station #3 and has been utilized for back -up power.
