Cross-Connection Control Program

Commercial Cross-Connection Control Program

Ensuring Clean, Safe Drinking Water and Regulatory Compliance is Chippewa Falls' top priority.

For years, Chippewa Falls has complied with an important Regulatory Water Safety Compliance Program known as Cross-Connection Control.

This State Mandated Program focuses on both residential and non-residential (commercial) water service connections and onsite visual inspections to identify potentially harmful interconnections to the Chippewa Falls Public Water Supply. While Chippewa Falls conducts residential inspections, the inspection of commercial buildings will be coordinated and performed by HydroCorp of Troy, MI.

For questions regarding commercial inspections, call HydroCorp at (844) 493-7646. For questions regarding residential inspections and appointments, call the Chippewa Falls City Utility Office at (715) 726-2741.

An Important Community-Wide Safety Project

The implementation of Cross-Connection Control Programs by Public Water Systems for water connections at both commercial and residential facilities is required by the Wisconsin Department of Natural Resources. 

This web page serves to assist Chippewa Falls 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 of their Commercial Cross-Connection Control Program. 

HydroCorp sends postal notice of upcoming Cross-Connection Inspection. Toll-Free hotline number provided for FAQ.

HydroCorp hired by local water purveyor to assist with CCC Program.

Facility owners have the option to coordinate the date of onsite inspection by HydroCorp.

Cross-Connection Surveyor arrives with I.D. and conducts survey/inspection with permission by owner/occupant.

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 Chippewa Falls to assist with their Cross-connection Control (CCC) Program. The CCC program includes two parts: On site inspections and testing of backflow prevention assemblies. The HydroCorp inspector will be conducting a visual inspection of the water uses outside of your facility (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. If your water provider requires an inspector to enter your facilty to evaluate other cross-connection and plumbing hazards inside your residence, you will be notified and instructed to schedule an appointment for your inspection.

Chippewa Falls has had a CCC program for 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 now required to be inspected for cross-connections. Initial residential inspections will occur from June 2021 through 2026. 

An average inspection normally takes from 10 to 20 minutes, depending on the size of your facility/property.

If you received a letter informing you/the facility of an upcoming cross-connection inspection, please arrange for the appropriate manager/person is aware of the planned inspection. Access will be necessary for the inspector to visually observe all exposed hot/cold potable water plumbing connections.

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 facility 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.

As required by Wisconsin Uniform Plumbing Code, backflow Prevention assemblies connected to Non-Residential plumbing shall be tested annually by an ASSE Certified Tester. 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.

There are two parts to the Cross-connection Control Program. The first is an on site inspection by a cross-connection control inspector to ensure that the proper backflow prevention devices and assemblies are in place to protect your drinking water. Some of the assemblies the inspector finds or asks you to install are testable assemblies, which are mechanical and can malfunction. The testing notice refers to testing the operation of these backflow prevention assemblies. These tests must be performed by a certified tester.

“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.
