RECOMMENDED ACTION: Approve specifications and authorize advertisement for bids for
Well 16 Granular Activated Carbon Replacement and adopt
resolution authorizing City Manager to award Contract to lowest
responsive bidder, in an amount not to exceed $180,000, or reject all bids, execute change orders in an
amount not to exceed $18,000, and appropriating funds in the amount of $198,000.
BACKGROUND INFORMATION: Granular activated carbon (GAC) is utilized at certain well sites to
adsorb dibromochloropropane (DBCP) and other contaminants in
the drinking water. Over time, the carbon loses its adsorptive
capacity and must be replaced. Recent test results indicate that while the current GAC in the vessels at
Well No. 16 have reduced adsorptive capacity and are ready for replacement, the water quality being
delivered to our customers meets or exceeds all State and Federal requirements.
Well No. 16 is located at 1490 West Century Boulevard (Exhibit A) and has three vessels with 22,000
pounds of GAC each. The GAC filter systems at these locations have been in service since 1994, with
the most recent GAC replacement in July 2011. Ihe total amount of GAC to be replaced with this project
is 66,000 pounds.
This project consists of removing the spent granular activated carbon (GAC) from Well Site 16 and
inspecting the vessels. After repairs are made by others (if needed), the contractor/supplier will furnish
and install domestic virgin GAC into the vessels and provide other incidental and related work.
The specifications are on file in the Public Works Department. The planned bid opening date is
November 18, 2020. The project estimate is $180,000.
Staff recommends authorizing City Manager to award Contract to lowest responsive bidder, in an amount
not to exceed $180,000, or reject all bids, execute change orders in an amount not to exceed $18,000,
and appropriating funds in the amount of $198,000.
FISCAL IMPAGT:This project is funded with proceeds from the City's DBCP settlement. This
project does not impact the General Fund.
