In 1974, Congress passed the Safe Drinking Water Act (SDWA) to protect the public health by regulating the nationís public water supply. Since 1974, the law has been amended in 1986 and 1996 to incorporate needed actions to protect the publicís water supply. Under this law, The City of Yuma is prohibited from installing or maintaining a water service connection to a consumerís water system within its jurisdiction, unless the public potable water supply is protected against backflow or backsiphonage by an approved prevention assembly(s) installed at the service connection or point of delivery.
The City of Yuma goes to great lengths to ensure that the water delivered to our citizens is of the highest quality. When water leaves the Main Street Water Treatment Facility, it is in its freshest and purest state. However, during delivery, there is a danger that the water may become contaminated or polluted from sources out of our control. This can happen when the water supply main, pipe, or service line is connected to equipment containing a substance not fit for drinking. These "cross connections" may be permanent or temporary and could cause the delivery of an unusable product, cause illness, or even death.
Cross Connection also can occur when a line break causes water to backsiphoned out of the building because of the lower water pressure at the point of breakage or leak.
