Cross-Connection Control Program
Residential Cross-Connection Control Program
Ensuring Clean, Safe Drinking Water and Regulatory Compliance is Hampton Township's top priority.
For years, Hampton Township has complied with an important Regulatory Water Safety Compliance Program known as Cross-Connection Control.
Until recently, this State Mandated Program focused on non-residential (commercial) water service connections and onsite visual inspections (coordinated and performed by HydroCorp of Troy, MI) to identify potentially harmful interconnections to the Hampton Township Public Water Supply.
HydroCorp will also be completing a Water Meter Replacement Program as part of the residential Cross Connection Control Survey. A dual-purpose project eliminates the need to repeat requests for residential access and onsite visits, and can usually be completed in less than 30 minutes.
Michigan Department of Environment, Great Lakes and Energy (EGLE) are now requiring Public Water Systems to implement a similar Cross-Connection Control Program addressing Residential Water Service Connections.
This web page serves to assist Hampton Township Water Customers with their participation in this important safety program. The Township has selected HydroCorp to assist with Coordination, Site Visits, Data/Compliance Management, and Water Meter Replacement. Replacement of the water meter is free and will lead to more accurate billing.

Cross-Connection and Backflow FAQ
PART I: INSPECTIONS / SURVEYS
A cross-connection is an actual or potential connection between the safe drinking water (potable) supply and a source of contamination or pollution. State plumbing codes require approved backflow prevention methods to be installed at every point of potable water connection and use. Cross-Connections must be properly protected or eliminated.
HydroCorp has been contracted by Hampton Township to assist with the Cross-connection Control (CCC) Program. The CCC program includes two parts: On-site inspections and testing of existing backflow prevention assemblies. The HydroCorp inspector will be conducting a visual inspection of the water uses outside of your home (outside spigots, lawn irrigation system, secondary sources of water, pools, etc.) to identify cross-connections that could possibly contaminate your drinking water or the public water supply.

Hampton Township has had a CCC program for a number of years, which began with inspections of all of the commercial and industrial accounts. As a natural progression of our program we are now inspecting residential customers as required by the State.
All water customers (residential and nonresidential) connected to the public water supply are required to be inspected for cross-connections. Due to the total number of homes that shall be inspected, not all inspections can be completed in 1 year. Therefore, the Hampton Township program is a 6-year program where all homes will receive the first inspection in any 1 year from 2021 thru 2026.
An average inspection normally takes from 10 to 20 minutes, depending on the size of your home/property.
YES – if you received a letter informing you to call and arrange for an appointment, someone over 18 must be home to allow our inspector to enter the home and complete the inspection. Water Customers can visit www.watercustomer.com OR call toll free HydroCorp Hot-line (844) 493-7646.
Yes. We just need a name and number so that the inspector can contact you to set up a time that is convenient for you.
If you are the owner of the home being inspected, you are responsible for any needed repairs. Renters may have to refer to their lease agreements in order to determine whether they are responsible for repairs.
All HydroCorp inspectors wear photo ID badges during inspections and are prepared to provide appropriate documentation verifying their identities.
Yes. These inspections are conducted in order to ensure compliance with state regulations to maintain the safety of your drinking water.
Penalties for refusing to cooperate with inspections and/or refusing to make needed repairs are determined by your local water utility. These typically can include termination of water service, a fine, or both.
PART II: BACKFLOW PREVENTION ASSEMBLY TESTING
PART III: GENERAL RESOURCES
The anti-siphon fill valve device is located in the tank of your toilet. This device has a dual purpose: To fill the toilet and prevent backflow. This device must be placed at the proper height in order to insure that water from your toilet does not backflow into your drinking water. Proper placement is typically done during the installation process but can be easily overlooked. This device must be raised or the overflow pipe must be cut down in order to achieve a 1” air gap separation between the “critical level” of the assembly.

Vacuum breaker should not be subject to continuous pressure like the example here illustrates. (This type of irrigation set up/system would need to be corrected.) |
These require periodic performance testing by a Certified Tester.
