DEPT. HD.
MTG. 4-11-89 CROSS -CONNECTION CONTROL PROGRAM CITY ATTY
DEPT. U/M
CITY MGR.
RECOMMENDED ACTION:
Title the ordinance by the first reading and set a public hearing for May 2,
1989 for Ordinance No./)S-Gz adopting Article 1 of Group 4 of subchapter 1
of Chapter 5 of Title 17 of the California Administrative Code.
ITEM EXPLANATIONt
Water agencies throughout California are required by State law to provide for
a Cross -connection Control Program. The City of Carlsbad, under the water
merger agreement, is required to establish and administer a cross -connection
control program. A cross -connection control program requires installation
of mechanical devices on customers water lines to protect water supply from
contamination. The mechanical devices, knrN,,i as backflow preventers, are
usually installed on the service lines of commercial, industrial, multiple
residential and agricultural premises. Backflow preventers are rarely
installed on single family residential service lines. (Refer to Exhibit 3 -
Type zf Backflow Protection Required.)
In the past, the City has operated a cross -connection control program in
compliance with provisions of the California Administrative Code, Title 17.
Essentially, these regulations provided for protection of the public water
supply through the installation of simple double-check val�,e backflow
preventers. Record keeping requirements were rudimentary and Cesting was not
required.
Recently, the State enacted more stringent requirements for public water
supply protection. The new regulations require that local agencies adopt
cross -connection rules and regulations which provide for:
1. Installation of more sophisticated and effective backflow preventers
on existing and new service lines.
2. Annual inspection of backflow preventers by qualified technicians.
3. Maintenance of records concerning the location, testing and repair
of backflow preventers.
The regulations also require each water agency to employ a person trained in
cross -connection control.
The new State regulations became enforceable on July 1, 1988, and City staff
has been enforcing the regulations since that time.
Based on the size of the customer's service line, installation of the new
backflow preventers will cost between $500-$800, the cost being born by the
individual user. Annual testing by private sector technicians will cost
between $75-$100, annually.
The proposed ordinance meets all State requirements for cross -connection
control and provides for testing by qualified private sector technicians.
The City presently employs staff trained in cross -connection control.
PAGE 2 OF AB# fI f%l
Since the proposed ordinance adopts by reference a portion of Title 17 of the
California Administration Code, the Government Code requires that a noticed
public hearing be conducted prior to adoption of the ordinance. Accordingly,
after first reading and titling of the ordinance, staff recommends that the
Council set the public hearing on May 2, 1989.
ENVIRONMENTAL IMPACT:
The installation of backflow preventers will prevent the possible
contamination of the potable water system.
FISCAL _IMPACT:
There will be no direct fiscal impact to the City in that those water users
required to install backflow devices will bear all costs associated with
installation, inspection and record keeping. The City will notify those
water• clients of the need to install, test or maintain the cross -connection
devices with the City maintaining records of annual tests. The cost of
notification and record keeping is marginal at this time and can be absorbed
within the present revenue of the Water Enterprise Fund.

abatement of cross -connections which may exist within a user's premises. As a

This includes chemical or biological process waters and water from public water .
supplies which have deteriorated in sanitary quality.

satisfaction of the water supplier or the health agency.
