Cross-Connection Control Program

Residential Cross-Connection Control Program

Ensuring Clean, Safe Drinking Water and Regulatory Compliance is Michiana's top priority.

The Michigan Department of Environment, Great Lakes, and Energy (EGLE) are requiring Public Water Systems implement an important Regulatory Water Safety Compliance Program known as Cross-Connection Control to address Residential Water Service Connections.

This State Mandated Program focuses on onsite visual inspections (coordinated and performed by HydroCorp of Troy, MI) to identify potentially harmful interconnections to the Michiana Public Water Supply.

An Important Community-Wide Safety Project

This web page serves to assist Michiana Water Customers with their participation in this important safety program. The city has selected HydroCorp to assist with Coordination, Site Visits, and Data/Compliance Management.

Water Customers can visit the website OR call toll free HydroCorp Hot-line (844) 493-7641

Cross-Connection Surveyor arrives with I.D. and conducts exterior inspection. Surveyor documents existing and any potential corrective actions, explains next step responsibilities to owner. Corrective actions instructions are also mailed via postal to building owner with compliance due date.

HydroCorp sends postal letter with instructions to set appointment.

Water Customer/Owner contacts HydroCorp when corrections are made and onsite compliance inspection is scheduled.

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 Michiana 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.

Michiana 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 Michiana 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.

Interior Inspections: 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 the www.watercustomer.com OR call toll free HydroCorp Hot-line (844) 493-7641.

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

Just like any other mechanical device, backflow prevention assemblies are prone to wear and tear, and do break down from time to time. Regular testing is required in order to ensure that your device remains in proper working order.

Michiana’s Cross-Connection Control Program requires a minimum testing frequency of every 3 years for irrigation system backflow prevention assemblies. If you are injecting chemicals into your lawn irrigation system, state regulations and plumbing codes require the backflow preventer to be tested on an annual basis.

“Grandfathering” is not typically permitted due to the high importance of maintaining drinking water safety. Just like any other mechanical device, backflow prevention assemblies are prone to wear and tear, and do break down from time to time. Regular testing is required in order to ensure that your device remains in proper working order.

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.
