Cross Connection Control Program
WE ARE ALL CONNECTED TO THE SAME PUBLIC DRINKING WATER SYSTEM
A cross connection is a link between a possible source of pollution and a potable water supply. A pollutant may enter the potable water system when the pressure of the pollution source exceeds the pressure of the potable water source or when a sudden loss of pressure occurs in the water system and backflow occurs.
Backflow or backsiphonage occurs when water flows backward through the water supply system. When the water is accidentally mixed with hazardous chemicals or bacteria, it is called dangerous!
How does contamination of water occur?
Water normally flows in one direction, from the public water system through the customer's plumbing to a plumbing fixture. Under certain conditions water can flow in the reverse direction. Potentially contaminated water from a customer's premise may backflow through an unprotected cross connection and enter the public water supply. There are two types of backflow - backsiphonage and backpressure.
What are some common areas where cross connections are a concern?
- Hose bibbs
- Cleaning/Mop Stations
- Lawn Irrigation Systems
- Fire Protection Systems
- Lab and Medical Equipment
- Photo Developing Equipment
The City of Jacksonville is required by State Regulations to have a plan and process to identify unprotected cross connections, and to ensure they are eliminated or protected with an approved backflow preventer to protect the public water supply. Some backflow preventers, or backflow prevention assemblies, require annual testing to ensure they are in proper working condition.
As required by State Regulations, the City of Jacksonville will be mailing out Cross Connection Control Survey Questionnaires that must be completed by you - the water customer, and returned to the City of Jacksonville. You may mail, fax, or e-mail your completed survey form back to us within the specified time frame.
The Jacksonville Water Supply will send you a notice instructing you to have your backflow prevention assemblies tested for performance. These assemblies must be tested every year. You may typically find assemblies on supplies to main service lines to a building, irrigation systems, fire sprinkler systems, boiler or other equipment.
- Complete the required Cross Connection Control Survey Questionnaire provided by the Jacksonville Water Supply.
- Keep the ends of your hoses clear of all possible contaminants and
- If not already equipped with in-line protection device, buy and install approved hose bibb vacuum breakers on all threaded faucets. (These devices do NOT require testing).
- Have all backflow prevention assemblies tested every year.
- Contact the Jacksonville Water Supply or Plumbing Inspector with any questions you may have about plumbing or equipment connections.
- Submerge hoses in buckets, vats, tubs, sinks, or ponds.
- Use spray attachments or valved spray hoses without a backflow preventer.
- Directly connect waste drain pipes from water softeners or other treatment systems to the sewer system. All drains should be air gapped.
