Cross-Connection Control Program

About the Program
The Water Department’s Cross-Connection Control Program is responsible for managing the various plumbing arrangements in the City of Jackson through which both potable (drinkable) water and non-potable (undrinkable) water flow. This program is necessary to assure that no contaminating backflow occurs into the drinking water supply.

Backflow is the reversal of normal flow in the drinking water system. It can occur when the pressure in a customer’s plumbing system becomes greater than the pressure in the city's water mains. If this situation occurs, there is the potential for contamination to enter the drinking water system by backsiphonage or back-pressure through a cross-connection (if one exists in your plumbing system).

Legal Responsibility
The Cross-Connection Control Program became necessary when the federal government enacted the Safe Drinking Water Act in 1974, placing responsibility for cross connection control on the local water supplier. The Water Supply Cross Connection Rules were adopted in 1978, by reference to the administrative rules under the Michigan Safe Drinking Water Act. To comply with this act, the City of Jackson adopted its own local ordinance:

City of Jackson Ordinance Sec. 27-44
It shall be the duty of the Water Department to cause inspections to be made of all properties served by the public water supply where cross-connections with the public water supply is deemed possible. The frequency of inspections and re-inspections based on potential health hazards involved shall be as established by the water department and as approved by the state department of public heath.

Based upon this responsibility, the City of Jackson Water Department put the Cross-Connection Control Program into place. This program involves inspecting commercial and industrial plumbing systems and testing backflow devices. We are not looking to find faults within the individual systems, rather eliminate all possibilities of contamination from entering our potable water system.
