Attention: Keith R. Till, City Manager
From: Stephen G. Badum, Director of Public Works/City Engineer
Subject: SUPPLY AND INSTALLATION OF HYPOCHLORITE
GENERATION SYSTEMS - 819
GENERAL DESCRIPTION
The proposed City Council action will approve the plans and specifications, and
authorize Staff to initiate the bidding process so that a contract may be awarded
in June for the supply and installation of hypo-chlorite generation systems.
DISCUSSION:
Currently, the City's water department uses the chlorine gas method to
chlorinate the City's water supply that is pumped from the ground. In 1997 the
OCFA notified the City that according to the UFC code that the past method
using chlorine gas was unacceptable in its present form. These facilities are 30 to
40 years old. Additionally, the Federal government has mandated any agency or
business with hazardous substances such as chlorine gas to submit a detailed
Risk Management Program (RMP) for these facilities along with the
requirements of the California Accidental Release Prevention Program (Ca1ARP).
Water and Engineering staff investigated a number of different options to
upgrade the water system to meet the improved safety requirements while
maintaining a cost effective maintenance operation. Scrubbers for the gas system,
containment vessels, aqueous chlorine were all examined. From discussions with
other Agencies and our own research yielded that on site chlorine generation
was the best possible option.
On site generation provides the City the power of chlorine gas without the
danger of storing or handling hazardous materials while providing a safe,
efficient and economical alternative. It operates automatically requiring only
water, salt and electricity. Agencies such as Santa Ana, Westminster, and
Fullerton have already begun the switch over. It also eliminates the preparation

of costly mandated reporting requirements to federal and state agencies.
Additionally, it reduces City personnel hazards due to handling of chemicals
while decreasing the risk to the environment and surrounding population.
Units will be installed at the Navy reservoir station and the Bolsa Chica Station.
Funds have been programmed for next year's budget to complete the stations at
Leisure World and Beverly Manor.
FISCAL IMPACT:
The estimated cost to construct, inspect and administer this project is
approximately $100,000. Funds are currently available from within the City's
Capital Improvement program under account 019-49819-062 and from savings
from 019-49728-062, 019-49730-062 due to the modification of the system.
RECOMMENDATION:
Staff recommends that the City Council approve the plans and specifications,
authorize staff to initiate the public contract bidding process.
