Cross-Connection Control Program

Residential Cross-Connection Control Program

Ensuring Clean, Safe Drinking Water and Regulatory Compliance is Crestview Water & Sanitation District's top priority.

For years, Crestview Water & Sanitation District 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 to identify potentially harmful interconnections to the Crestview Public Water Supply.

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

An Important Community-Wide Safety Project

Section 11.39 of the Colorado Department of Public Health & Environment Water Quality Control Commission’s Colorado Primary Drinking Water Regulation requires that the supplier must develop a written backflow prevention and cross-connection control program. Cross-connection control focuses on eliminating or protecting hazardous interconnections in the public water supply system which, in the event of a backflow incident, could inject pollutants and contaminants into the drinking water.

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 Crestview Water & Sanitation District to assist with their Cross-Connection Control (CCC) Program.  The CCC program includes two parts: On-site inspections and verification of existing backflow prevention assemblies and annual test results.  The HydroCorp inspector will be conducting a visual inspection of your home to verify the existence of a testable backflow prevention device relating to your fire suppression system.

Crestview has had a CCC program for a number of years, which began with inspections of all of the commercial and industrial accounts. It was determined that your home has a 13D fire suppression system installed within it and is required by the State of Colorado to verify the existence of a backflow prevention device for the 13D system and review testing results.

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 Crestview program is a 4-year program where all homes with a fire protection system will receive the first inspection in any 1 year from 2025 thru 2028.

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

Yes, HydroCorp will need to enter your home to inspect the existing 13D fire suppression system backflow prevention device.

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 Crestview Water.  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.

Backflow Prevention Assemblies connected to public water system plumbing are required to be tested annually by an ASSE Certified Tester per the State of Colorado.

“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. If after a failed test, the device cannot be repaired and pass testing, the device must be replaced with a new backflow prevention assembly meeting current standards.

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.

HydroCorp has been contracted by Crestview Water & Sanitation District 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 Crestview requires an inspector to enter your facility to evaluate other cross-connection and plumbing hazards inside your residence, you will be notified and instructed to schedule an appointment for your inspection.

Crestview has had a CCC program for years, which began with inspections of all of the commercial and industrial accounts. Denver Water has been conducting the inspections in the past however, Crestview will be utilizing HydroCorp to perform these site surveys beginning January 1, 2025.

All commercial water customers connected to the public water supply are required to be inspected for cross-connections.  Crestview’s Cross Connection Control program is a 4-year program where all commercial properties will receive the first inspection in any 1 year from 2025 thru 2028.

Depending on the size of your facility/property, the inspection time could range from 10 minutes to an hour.

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.

Backflow Prevention Assemblies connected to public water system plumbing are required by the State of Colorado to be tested annually by an ASSE Certified Tester.

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. Annual testing is required in order to ensure that your device remains in proper working order.
