What Is A Cross-Connection?

A cross-connection is any temporary or permanent connection between a public water system or the customer’s potable water system and any source or system containing non-potable water or other substances.

Common cross-connections

  • Private Wells – where the private well connection is connected to a service line receiving water from a public water supply.  The untreated water could be pumped into the potable water supply which serves the home and the public water system.
  • Lawn sprinkler systems – where the stagnant/contaminated water from the sprinkler system could be drawn into the drinkable water supply for your home.
