Cross-Connection Program/Backflow Prevention


The city expends great effort to protect the public water supply from the possibility of contamination or pollution while it flows through the distribution system. It is possible for contamination or pollution to enter the system when a water supply line is connected to equipment containing a non-potable (unfit to drink) substance. These connections, called cross-connections, whether they are permanent or temporary would be dangerous if no protective measures were taken. Back-flow preventers are designed to keep contamination or pollution from entering the distribution system.
