Water Tank Rehabilitation Recommendations: Marvin Fielding from Keller Associates
presented a cost summary of the water tank rehabilitation recommendations. DN Tanks and
Material Testing and Inspection (MTI) report shows recommendations for an exterior coating on
the tank and the lid. Mr. Fielding talked with a structural engineer who recommended not doing
that because once you do that its ongoing maintenance.
They are recommending a side man entryway for approximately $76,000. The Department of
Environmental Quality (DEQ) requires two entryways above the water line. Keller Associates
would like to recommend converting the existing one to a removal vent/access and then add a
second one above the water line.
In regards to the wall cracks, they seem to be superficial, and would cost approximately $34,000
to repair. As a result, he is not sure it is worth doing. However, they would recommend that the
floor joints and cracks in the floor be blasted, cleaned, and patched. At this time there is no
evidence the roof is leaking, but for preventative maintenance they would recommend going in
and routing out the cracks and putting a flexible sealant on the outside surface on the top of the
tank.
For access improvements, Mr. Fielding would recommend doing an exterior ladder around the
backside with a cage and ladder guard, as well as, an interior ladder over 20 feet long.
Mr. Fielding covered a couple of tank accessories such as the existing overflow pipe size, the
vent size, and mixing alternatives.
He explained they did find some voids, but they appear to be insignificant in the diagonal joints
on the floor. Keller Associates feels confident that by sealing the floor joints they do not need to
address the voids.
In conclusion, the concrete looks good and the seepage test showed you are leaking about 2 1/2
gallons per minute which calculates out to 35,000 gallons a day, but has been over 43,000
