COUNCIL COMMUNICATION
AGENDA TITLE: Adopt Resolution Authorizing City Manager to Approve Repair of GAC Treatment Vessels
for DBCP Treatment at Well No. 4R by Gold Star Painting, of Turlock, CA ($22,170)
MEETING DATE: May 21,2008
PREPARED B Y Public Works Director
RECOMMENDED ACTION: Adopt a resolution authorizing the City Manager to approve the time -
sensitive repair of granulated activated carbon (GAC) treatment vessels
for dibromochloropropane (DBCP) treatment at City drinking water Well
No. 4R by Gold Star Painting, of Turlock, CA.
BACKGROUND INFORMATION: The City operates GAC treatment systems for the removal of DBCP at six
of the City's 26 drinking waterwells. The operation and maintenance of
these systems is paid for underthe terms of the DBCP settlement with
Shell, DOW, et al. The GAC system at Well No. 4R was recently taken
out of service for replacement of the spent carbon. Standard procedure includes inspecting the internal surfaces
of the vessels. The under -drain coating was found to be in very poor condition. Since the vessels will not be
opened for carbon replacement for the next six to seven years, the coating specialist recommended the interior of
the vessels be sandblasted down to metal and recoated with the new technology epoxy coating for drinking water
applications in order to avoid the possibility of major metal failure. Three informal bids were received from
qualified contractors. Staff recommends award to Gold Star Painting, of Turlock, CA, for their low bid of $22,170.
This well cannot be used without GAC treatment for DBCP. The drinking water system needs to have this well
operational for upcoming hot weather demands since currently three other wells are off line — two with motor
problems and one for carbon change -out. The process for preparation, repair, coating, and reassembly will take
two to three weeks, and then the new carbon must be installed, flushed, and tested before the well can be put on
line. The entire process could take up to five weeks, which would complete the process in late June.
Staff recommends Council authorize the City Managerto approve the time -sensitive repair of GAC treatment
vessels for DBCP treatment at City drinking water Well No. 4R by Gold Star Painting.
FISCAL IMPACT: This project will be funded from the Water Utility DBCP Operations and
Maintenance account. Revenues to fund this activity are reimbursed under the
terms of the DBCP settlement. Therefore, the Water Fund is not fiscally impacted.
If the coating is not performed, the City has the following options: 1) keep the well out of service and
jeopardize the reliability of the drinking and fire fighting water supply, or 2) operate the vessels without coating
and risk maior metal failure in the vessels, resulting in much more costly repairs.
FUNDING AVAILABLE: The %V2A urrent1y budgeted in the Water Utility Fund (180454)
