TITLE:
AWARD CONTRACT TO MANUFACTURE AND INSTALL AN
EMERGENCY CHLORINE SCRUBBER SYSTEM AT THE
CARLSBAD SWIM COMPLEX
RECOMMENDED ACTION:
Adopt Resolution No. aa I- ,134 accepting the proposal of $139,070 and awarding the contract
to Knorr Systems, Inc. to manufacture and install an emergency chlorine scrubber system at the Carlsbad Swim Complex.
lTEM EXPLANATION:
Owners and operators of high volume swimming pools, water parks, water features and water
amusement attractions often demand the use of chlorine gas, as it is the most economical and
efficient method of water disinfections. The City uses chlorine gas at the Carlsbad Swim Complex.
While chlorine gas is the most economical and efficient method to disinfect water, it does have its risks. An emergency chlorine scrubber system will prevent toxic chlorine gas from escaping into the
atmosphere and avert a potential health and safety concern to the public.
On December 11, 2000, staff began soliciting proposals for an emergency scrubber system at the
Carlsbad Swim Complex. Two proposals were received, opened, witnessed and recorded on
January 25, 2001. The two proposals received were as follows:
Knorr Systems, Inc. $139,070
Olsson Construction $143,479
After extensive review of both proposals, staff determined that the testing conducted on the chlorine
scrubber from Olsson Construction did not meet the requirements specified in the Request for
Proposal (RFP). On the other hand, the proposal submitted by Knorr Systems did comply with all
the requirements specified in the RFP. In addition, staff is familiarized and has a good understanding of Knorr Systems products because the City is currently using their chlorine
scrubbers for CMWD operations.
Therefore, staff is recommending that Council accept the proposal of $139,070 and award a
contract to Knorr Systems, Inc to manufacture and install an emergency chlorine scrubber system at
the Carlsbad Swim Complex.
ENVIRONMENTAL REVIEW:
This project has been determined to be categorical exempt from environmental review per CEQA -
Section 15301.
FISCAL IMPACT:
The estimated cost for this project is $139,070. There are sufficient funds in the City’s C.I.P.
Program budget and in the Recreation Operations budget to complete this project.
EXHIBITS:
1. Resolution No. da/* 134 accepting the proposal of $139,070 and awarding the contract to Knorr Systems, Inc. to manufacture and install an emergency chlorine scrubber system at the
