7. Resolution 4245 - Emergency - Repairs to Gravity ThickenerRESOLUTION NO. 4245
A RESOLUTION DECLARING AN EMERGENCY AND AUTHORIZING THE PUBLIC
WORKS DEPARTMENT TO PROCEED, WITHOUT ADVERTISEMENT OR BIDDING, FOR
REPAIRS TO THE GRAVITY THICKENER AT THE WASTE WATER TREATMENT
PLANT.
WHEREAS, the corrosive environment within the gravity thickener at
the Waste Water Treatment Plant has led to a failure of
protective coating on the concrete walls; and
WHEREAS, without protective coating the concrete walls of the
gravity thickener may fail causing serious damages to the
sewer treatment plant, and
WHEREAS, long term treatment of waste water to remove phosphorus,
a function accomplished in the gravity thickener, with
alum is costly, and
WHEREAS, the Public Works Department has determined that the
remedy for the problem will be to sandblast the interior
walls of the gravity thickener to remove the remaining
protective coating and coating the walls and roof of the
tank with a glass flake epoxy coating, and
WHEREAS, the estimated cost of repairs as determined by the Public
Works Department is over $50,000, requiring advertisement
and competitive bidding under S 7-5-4302, MCA, and
WHEREAS, S 7-5-4303, MCA authorizes a City to proceed without
observing S 7-5-4302, MCA when an emergency exists and
three -fourths of Council present at a meeting authorize
a procedure which best meets the emergency and serves the
public interest.
NOW, THEREFORE, BE IT RESOLVED BY THE CITY COUNCIL OF THE CITY OF
KALISPELL, AS FOLLOWS:
SECTION I. That the deteriorating condition of the
protective coating on the gravity thickener at
the waste water treatment plant constitutes an
emergency under S 7-5-4303, MCA, thereby
abrogating the City's responsibility to
advertise and bid repairs.
SECTION II. That the Public Works Department, under the
direction of the City Manager, is authorized
and directed to proceed and solicit proposals
from qualified contractors to remove the
existing coating and replace it with a glass
flake epoxy substance, at a cost not to exceed
$80,000.
RESOLUTION 4245 1
SECTION III. That funds necessary to accomplish repairs to
the gravity thickener as recommended by the
Public Works Department shall be expended from
moneys held for replacement in the Waste Water
Treatment Fund.

Memorandum
Date: November 9, 1995
To: Bruce Williams, City Manager
From: John Wilson, Assistant City Engineer-JCI.c�
Re: WWTP - Gravity Thickener Repairs
This memo is a request for authorization to solicit contractor's proposals for the
installation of inspection ports and recoating of the gravity thickener. Our updated
estimate for the project is $50,000.
Over the past week we have evaluated the corrosive environment of the gravity thickener
and researched various methods of corrosion protection. Based on that analysis, we
have chosen to sandblast the remaining tar coating from the walls and roof of the tank
and apply a new glass flake epoxy coating. This material will be applied with an airless
sprayer, much like house paint. But given the confined working environment and special
techniques associated with epoxy materials, the cost is estimated to be considerably
higher that the average paint job.
Three or four local contractors will be asked to submit proposals by November 27, when
I will be back in the office. We intend to order materials and proceed with repairs by
mid -December.
The contractor's proposals will include the installation of a series of inspection ports.
These will provide much needed access for future maintenance and inspection. The
proposals will also provide for sandblasting and preparation; scaffolding, heating and
ventilation as required; equipment and labor to apply the new coating; and cleanup. We
will order and provide the inspection ports and epoxy coating materials.
We have reasonably firm costs on sandblasting and materials, but it's hard to predict how
contractors Aill respond to the requirements of working with special materials in a
confined space.
