CITY COUNCIL AGENDA REPORT
MEETING DATE: APRIL 15, 2019
AGENDA #: 5F
PREPARED BY: JASON WEDEL, PUBLIC WORKS DIRECTOR/CITY ENGINEER
PRESENTED BY: NICK MONSERUD
AGENDA ITEM: CONSIDER APPROVAL OF A RESOLUTION AUTHORIZING THE
PURCHASE OF A BRINE PRODUCTION EQUIPMENT AS SET FORTH
IN THE CAPITAL IMPROVEMENT PROGRAM
GOAL AREA
AND
OBJECTIVE:
DISCUSSION:
Environmental Stewardship & Recreation
5. Employ emerging technologies to preserve and protect our natural
resources.
Introduction
The purpose of this agenda item is to seek City Council approval to the
purchase of new brine equipment.
History
The City began utilizing salt brine as part of snow management program in
2006. The brine is used to pretreat City streets prior to snow events. For
lighter snow falls, the brine treatment will keep the streets clear without the
need for plowing and for larger snow events the brine treatment prevents
the snow from adhering to the roadway surface which facilitates easier
removal with the plows. The brine is also used to wet the salt as it exits the
plow trucks which activates the chemical reaction and expedites the
melting of the snow on the pavement.
Included in the approved 2019 Capital Improvement Plan is the
replacement of the existing equipment. The existing equipment is starting
to fail and it is very labor intensive to operate. Replacement this year is
therefore necessary.
Current Circumstances
As part of staff’s due diligence to research various brine making
equipment, visits were conducted at several cities that have newer brine
making equipment. This included visits to the cities of Eden Prairie and
Bloomington. After these visits staff proceeded to obtain quotes from two
different vendor which were Aspen Equipment and Varitech Industries.
Varitech is the manufacturer of the City’s current brine system. Their latest
product line includes a significant number of advances that the City’s
current system does not currently have. This includes being able to set the
specific blend that is required and the equipment will automatically pump
from the various tanks to create the exact blend automatically. Currently,
2
City staff have to manually pump from the various tanks and test the brine
being produced to determine if the appropriate blend is being created. This
is a cumbersome and time consuming process. It is also fairly complicated
so that only a few staff are currently able to complete this process. The
computer interface with the new equipment is intuitive and easy to use.
This will allow multiple users to operate the equipment and provide more
flexibility from a staff perspective. The City of Eden Prairie has this system
and they spoke highly of it.
The other manufacturer the City received a quote from was Aspen
Equipment. The benefit of this system was that it was lower in price, but it
is not nearly as user friendly. It uses stack mixing so depending on the
specific blend that is needed for a snow event, the equipment turns valves
on and off to switch between tanks and create the requested blend. It then
needs to be combined in another tank so that it can be properly mixed
together. The equipment is more complicated to operate and only
specifically trained staff would be able to operate it. This is the system that
both the cities of Bloomington and Orono have and neither of them was
completely satisfied with it.
Conclusion
Staff is recommending the purchase of the Varitech Industries brine
equipment. The additional cost will be offset by the quality of the brine
mixtures being produced and the ease and flexibility of operations and the
ability to have multiple staff operate the equipment. The Council is being
asked to authorize the purchase of the new equipment.
ISSUES: There are no issues anticpated with this purchase.
FINANCIAL
IMPACT:
The Council approved the 2019 budgets and tax levy as part of the
December 3rd, 2018 City Council agenda. This authorization for purchase
of this equipment is in accordance with the 2019 budget as presented for
the equipment replacement program as approved in the 2019 CIP.
The 2019 Equipment Replacement Plan (CIP) and the 2019 revolving
Equipment Fund budgeted $99,960.00 for the replacement of this
equipment.
The quote received from Varitech Industries is $75,690 and the quote from
Aspen Equipment is $66,249. The Varitech Industries equipment is
therefore $9,441 higher. However, the quality of the brine product
produced by the Varitech system coupled with the enhanced user interface
which allows multiple staff to operate it is worth the additional cost. In
addition, the total cost for the Varitech system is still well within the budget
included in the 2019 CIP.
ALTERNATIVES: 1. Motion and second to approve a resolution as part of the consent
agenda authorizing the purchase of the nine pieces of equipment
and appurtenant equipment as detailed in this report.
2. Motion and second to remove this item from the consent agenda for
additional discussion.
