Workshop Memorandum 18-058

Subject: Status Report on the Emergency Repairs for Drinking Water Reservoir 17.1.1

On November 21, 2017, the Board of Directors
authorized emergency coating repairs for
drinking water reservoir R-17.1.1 with Superior
Tank Solutions [Director Memorandum No. 17-
108].

On Monday, January 29, 2018, Superior Tank
Solutions began repairs. Upon removing the
coal tar enamel from the floor it was evident that
the floor is in need of replacement, not repair.
The existing floor consists of numerous welded
patches in various sizes and thousands of pits
from erosion. This metal has been worn thin and
is now a liability to the District. The side shell has
approximately ten holes that will be repaired.

Attached is the additional cost for the
recommended work needed. This includes
replacing the floor, replacing the hatch, adding
one roof vent to conform to State standards,
and replacing the water level indicator as the
existing one is damaged. The District received
a credit in the amount of $7,556.50, for the
repair that will not be completed on the existing
floor, as this was included in the original scope
of work. The total additional cost for the revised
scope of work is $40,739.50. This is $1,500
less than shown below due to the installation of
only one roof vent.
