What is Cross Connection?
CROSS CONNECTION: Any physical arrangement
whereby a public water supply is connected, directly or
indirectly, with any other water supply system, sewer,
drain, conduit, pool, storage reservoir, plumbing fixture, or
other device which contains or may contain contaminated
water, sewage, or other waste or liquids of unknown or
unsafe quality which may be capable of imparting
contamination to the public water supply as a result of
backflow.

Educate & Ask for
compliance
•Educate and Enforce
•Something else
Depending upon magnitude of effort,
additional staff or outsourcing may be
needed.
• Historical attempts have proved controversial:
• Steve Smart tried to enforce in 2012
Sent letters notifying residents of testing requirements with
compliance deadline. ("after 32 years of not enforcing")
Potential liability to the City.
• Risks of infecting residents with Giardia,
Cryptosporidium, E. Coli, etc.
• Idaho Administrative Code — IDAPA 58.o1.o8
"The water purveyor is responsible ... to take reasonable
and prudent measures to protect the water system
against contamination and pollution from cross
connections... The water purveyor is responsible to
enforce the system's cross connection control
program."
