City of City Council Report
Santa Monica'
City Council Meeting: October 23, 2012
Agenda Item: 3—C
To: Mayor and City Council
From: Martin Pastucha, Director of Public Works
Subject: Bid Award for Reverse Osmosis Chemicals
Recommended Action
Staff recommends that the City Council award Bid #4021 for the purchase and delivery
of reverse osmosis antiscalant chemicals to King Lee Technologies, a California -based
company, in an amount not to exceed $185,000 for one year, with two one -year renewal
options at the same price, terms and conditions, for a total not to exceed amount of
$555,000 over a three -year period.
Executive Summary
The reverse osmosis filtration system at the Arcadia Water Treatment Plant (Arcadia) is
a critical component of the City's domestic water supply. In order to prevent mineral
and scale build up on the surface of the membranes, continuous treatment with reverse
osmosis antiscalant chemicals is needed. Reverse osmosis antiscalant trials were
conducted by staff during FY 2011/12 at Arcadia in order to determine acceptable
dosage and pH levels needed to achieve satisfactory performance. In August 2012, the
City solicited bids for reverse osmosis antiscalant. After evaluating the seven bids
received, staff recommends King Lee Technologies as the best bidder to supply reverse
osmosis antiscalant chemicals for a total not to exceed amount of $555,000 over a
three -year period.
Discussion
Scaling and fouling of reverse osmosis membranes are limiting factors in the amount of
ground water that can be recovered during treatment. Additionally, the expected five -
year service lifetime of the membranes is reduced if scaling and fouling are not properly
controlled. The use of a reverse osmosis antiscalant is the accepted method of
controlling scaling and fouling. Because every water source differs in mineral content
and physical characteristics, there is no exact method to determine the optimum
product, dosage and pH combination that would work best for a given water source.
For this reason, antiscalant trials were conducted by staff which resulted in a number of
1
product dosage and pH combinations that demonstrated the ability to limit scaling to an
acceptable level.
Vendor Selection
In August 2012, the City published Notices Inviting Bids to provide reverse osmosis
antiscalant chemicals as required by the Arcadia Water Treatment Plant in accordance
with City specifications. The bid was posted on the City's on -line bidding site, and
notices were advertised in the Santa Monica Daily Press in accordance with City
Charter and Municipal Code provisions. Seven bids were received and publicly opened
on August 28, 2012 per Attachment A. Bids were evaluated based on price, references,
experience, and compliance with City specifications. Based on these criteria, King Lee
Technologies is the best bidder to provide reverse osmosis antiscalant chemicals as
they are the lowest price bidder that is able to meet City specifications.
Financial Impacts & Budget Actions
The purchase order amount to be awarded to King Lee Technologies is $185,000.
Funds are available in the FY 2012 -13 budget in division 673. The purchase order will
be charged to account 05673.544011. Budget authority for subsequent years will be
requested in each budget cycle for Council approval. Future funding is contingent upon
Council approval.
