- To protect the public water supply system from contamination
or pollution by isolating within the customer's water system
contaminants or pollutants which could back flow through
the service connection into the public water supply system.

connections, actual or potential, between the public or
customer's potable water system and non-potable water systems,
plumbing fixtures and sources or systems containing substances
of unknown or questionable safety.
- To provide for the maintenance of a continuing program
of cross connection control which will prevent the contamination
or pollution of the public and customer's potable water
systems.
- To protect the public water supply system from contamination
or pollution by isolating within the customer's water system
contaminants or pollutants which could back flow through
the service connection into the public water supply system.
- Application. These Rules and Regulations shall apply
to all premises served by the public potable water supply system
of the Town of Normal.
- Owner's Obligation. The owner of property shall be responsible for protection of the public water supply system from contamination due to back flow or back siphonage of contaminants through the customer's water service connection.
