MEMORANDUM
DATE: March 3, 1993
TO: Honorable Mayor and Board of City Commissioners
FROM: James W. Shira, P.E.
City Engineer/Utilit es Director
SUBJECT: Repair of Water Well at Jamela Water Plant
At the January 19, 1993 Commission meeting you approved the
emergency repair of a well at the Jamela water plant. At that time
I reported to you that I was unable to provide a precise
description of the work required or of the anticipated final cost
until the well column had actually been pulled out of the ground
and had been inspected.
When our contractor, Layne-Atlantic Company, pulled the well column
out of the ground, it was apparent that it was in much worse shape
than had been anticipated. We had expected to find A hole in the
column at some point, but found instead that every section of
column pipe was riddled with holes. The contractor had to replace
all 140 feet of column pipe, and had to replace one of the pump
bowl assemblies which was eroded too badly to repair.
The casing was viewed with a television camera to make sure that no
perforations of the casing were seen, and it appears that the
casing is still in good condition. The well has been repaired and
is now back in continous operation. This well had been in
continuous service since the early seventies, with no maintenance
that we know of. We should not have this sort of experience with
the newer wells, since we plan to pull each well column at
approximately five to eight year intervals for inspection.
At the January 19 meeting, an authorization in the amount of
$10,000.00 from the Water Repair and Renewal account was given for
this repair based on our estimate of the damage to be found. As
stated above, the damage was much more extensive than had been
anticipated, and the total cost of the work is $21,039.62.
I recommend that the City Commission authorize an additional
$11,039.62 from the Water Repair and Renewal account to pay this
invoice.
