RECOMMENDED ACTION: Approve plans and specifications and authorize advertisement for
bids for Well 28 Granular Activated Carbon System, adopt
resolution authorizing City Manager to award Contract to lowest
responsive bidder, in an amount not to exceed $1,400,000, or reject all bids, execute change orders in an
amount not to exceed $140,000, and appropriating funds in the amount of $510,000.
BACKGROUND INFORMATION: ln 2017, Well 28 was removed from service in anticipation of the
new State drinking water standards for the regulated chemical
known as 1,2,3,- trichloropropane (1,2,3-TCP). This project is
needed for the well to meet State drinking water standards and return to service.
For decades, Granular Activated Carbon (GAC) has been utilized at several well sites within the City to
adsorb dibromochloropropane (DBCP). The State Water Resources Control Board has identified GAC
as a best available technology for also removing 1,2,3-TCP contamination from drinking water.
This project consists of furnishing and installing a GAC treatment system for Well 28, located at 2800
Kettleman Lane, as shown on Exhíbit A. The work for this includes furnishing and installing a GAC filter
system, complete with four low profile tanks, carbon media, concrete pad, and all required on-site piping
and valving, including approximately 90 linearfeet of B-inch water pipe,231 linearfeet 12-inch water
pipe, 156 linear feet of 14-inch water pipe, and 90 linear feet of eight-inch wastewater pipe, and other
incidental and related work.
The plans and specifications are on file in the Public Works Department. The planned bid opening date
is November 18,2020. The project estimate is $1,300,000. The work is anticipated to be complete by
summer 2021.
Staff recommends authorizing City Manager to award Contract to lowest responsive bidder, in an amount
not to exceed $1,400,000, or reject all bids, execute change orders in an amount not to exceed
$140,000, and appropriating funds in the amount of $510,000.
FISCAL IMPACT:Annual operation and maintenance costs for the water utility will increase as
a result of Well 28 being placed back into service with the addition of the
GAC treatment system. This project does not impact the General Fund.
