1. CROSS CONNECTION CONTROL PROGRAM

2. PURPOSE
Required by Section 7584 of Title 17, CCR, to protect water system from actual/potential cross connections
Importance:
Consumers assume water from the tap is safe
Can cause illness and death.
Can contaminate even the highest quality water.
Contamination may affect a single structure or may involve an entire community.

3. WHAT IS A CROSS CONNECTION ?
Actual/ potential unprotected connections between a potable water system and any source or system containing unapproved water or a substance which is not safe.

4. Examples of Cross Connections
Improperly installed irrigation systems
Improperly plumbed water using devices: hot-tubs, boilers or commercial dishwashers
Irrigation systems served by an auxiliary source, i.e. private well
Interconnections between potable system and a non-potable system

5. WHAT THE PROGRAM INCLUDES
Adoption of Rules/ordinance
Conducting the survey
Installation of devices
Provision of trained person
Procedure for testing
Maintaining records of locations/tests/repairs

6. GETTING STARTED Adopt an ordinance or set of rules
Important since it establishes the legal authority to carry out the program.
Conduct a system survey
Abate hazards by installing backflow prevention assemblies at the meter or providing internal cross-connection protection.

7. THE SURVEY Residential areas
Auxiliary water supply (i.e. either a well, pond, spring, or a creek pump)
Irrigation systems
Private storage tank
Swimming pool, hot tub or spa
Solar hot water heating panels
Graywater systems -
Animal troughs
Backflow prevention assemblies may not be required if the system is installed in accordance with the UPC.

8. THE SURVEY Commercial areas – more complex
Irrigation systems w/ chemigation/fertilization
Fire protection systems
Processing plants
Waste water treatment
Marine facilities

9. THE SURVEY Commercial areas – cont. System only has control to meter
Require BFD at all service connections
Health Dept.’s concern is protection of employees/public

10. THE SURVEY Wastewater and Hazardous Wastes Sewage treatment facility
Use of reclaimed water
Doctor/Dentist office
Aquarium
