Backflow Prevention and Cross Connection

Backflow is an undesired reversal in the normal direction of water flow. The normal direction is from the EWW water system to the customers; a backflow or cross connection would be from the customer to the EWW water system. EWW must protect the public water system and its Cross Connection Control Program empowers its staff to do so. The installation of an appropriate backflow preventer will protect the public water system from possible contamination.
