AGENDA TITLE: Adopt Resolution Awarding Contract for Well 27 Granular Activated Carbon Filter
System to Diede Construction, Inc., of Woodbridge ($1,063,900), Authorizing City
Manager to Execute Change Orders ($54,000), and Appropriating Funds
($322,900)
MEETING DATE: April 15, 2020
PREPARED BY: Public Works Director
RECOMMENDED ACTION: Adopt resolution awarding contract for Well 27 Granular Activated
Carbon Filter System to Diede Construction, Inc., of Woodbridge, in
the amount of $1,063,900, authorizing City Manager to execute
change orders in an amount not to exceed $54,000, and appropriating funds in the amount of $322,900.
BACKGROUND INFORMATION: In 2018, after the January sample for Well 27 indicated the
presence of the regulated chemical known as 1,2,3,-
trichloropropane (1,2,3-TCP) the well was taken out of service. 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 removing 1,2,3-TCP contamination from drinking water.
This project consists of furnishing and installing a GAC treatment system for Well 27, located at 2160
West Century Boulevard (intersection of Heavenly Way and West Century Boulevard), as shown on
Exhibit A. The base bid includes furnishing and installing a GAC filter system, complete with four low
profile tanks, concrete pad, required on-site piping and valving, including approximately 200 linear feet of
10-inch water pipe, 100 linear feet of eight-inch water pipe, and 60 linear feet of eight-inch wastewater
pipe, and other incidental and related work
The price for supplying carbon media was addressed as alternate bid items for either 100 percent virgin
coal-based carbon media produced in the United States; 100 percent virgin coal-based carbon media
produced outside the United States; or 100 percent virgin coconut media. After reviewing bid results,
City staff recommends using 100 percent virgin coal-based carbon media produced in the United States
for its high and long-lasting performance, based on past City experiences and comfort level as a quality
product.
This site has always been anticipated to need a GAC treatment system. As a courtesy, staff recently
sent a letter to neighboring home owners advising of the site impacts associated with the proposed
project. A rendering was also provided, reflecting the low profile vessels and proposed landscaping.
