Cross Connection Control
The Wauwatosa Water Utility routinely checks municipal water to ensure it is safe for potable use.  In accordance with the City's Cross Connection Control Program as mandated by the Wisconsin Department of Natural Resources, the utility will be performing periodic inspections/surveys for cross connections of the water supply.  This inspection program is designed to protect public health and to protect our public water supply system.

Residential property inspections will be scheduled to occur in conjunction with any water meter maintenance or replacement appointments.  The inspection is performed by Water Utility personnel and usually takes only 10 to 15 minutes of time.  The most typical example of a potential cross connection is the outside water hose bibb/spigot not containing a backflow prevention device on it.  Newer homes will normally include backflow devices on the outside hose bibb/spigot.

Cross connection inspections are also a DNR requirement for commercial and industrial properties in the City and are scheduled to occur every two years.  The Water Utility contracted with Aqua Backflow of Elgin, IL to manage the City's commercial and industrial cross connection control program.  The Utility asks for your cooperation when Aqua Backflow calls to schedule an appointment or asks for information. 

Compliance with the Cross Connection Control Program is mandatory for all water users.
