BOARD OF SUPERVISORS
FROM : Supervisor Tom Torlakson Contra
Costa
DATE'. October 28, 1986 Court/
SUBJECT: PREVENTION OF BACKFLOW WATER CONTAMINATION
SPECIFIC REQUEST(S) OR RECOMMENDATION(S ) & BACKGROUND AND JUSTIFICATION
RECOMMENDED ACTION: Refer the issue of backflow water
contamination (attached informational bulletins) to the Water
Committee with staff support from the Community Development
Department, Environmental Health staff, and the ,Building Inspection
Department to:
• provide a report on how the state laws regarding
anti-siphon valve installations and blackflow prevention devices are
being implemented by the Building Inspection Department;
• conduct a survey of each city to determine the level of
enforcement or implementation of state laws regarding anti-siphon
valve istallations and backflow prevention devices and express the
county' s concern;
• provide a report to the Board on what actions the county
can be taken with regard to backflow prevention.
BACKGROUND INFORMATION: This Board of Supervisors has gone
on record repeatedly as supporting significant efforts to reduce water
pollution and especially possible contamination of our drinking water.
A number of State laws exist regarding anti-siphon valve
installations and backflow prevention devices. However, it has come
to my attention that several cities are not implementing these codes
and that building inspectors are not enforcing these requirements.
I suggest that a survey be conducted requesting each city to
indicate the level of enforcement or implementation they are
undertaking currently and express our concerns in this matter for safe
drinking water.
A film is available from the Texas Plumbing Company showing
how lawn fertilizers, insecticides, and other toxic chemicals can be
readily sucked into the household drinking supply if the valve
breakers and back-flow prevention devices are not in place. Perhaps
this film can be shown to our building inspectors and to those in
other cities.
