Cross Connection

   

Cross Connection

A cross connection control device prevents water from reversing flow from the customer’s premises to the public supply water main.  A potential health risk can exist should a backflow situation occur if containers holding chemicals such as cleaning products or pesticides are connected to the water supply.  The greatest potential for this to occur is through your home’s garden hose, or through an underground sprinkler system.  If the water supply experiences a large drop in pressure at the same time a hose is left in a bucket or connected to a spray attachment, the chemicals could be siphoned into your home’s plumbing and potentially into the public water supply. All newly constructed residential homes and properties with underground sprinklers systems have been required to install cross connection control devices. 

Leyden Township Cross Connection Control Program

The Illinois Environmental Protection Agency (IEPA) requires all municipalities and private water companies to provide safe, potable water to its customers. In accordance with current IEPA regulations, all communities, including Hoffman Estates, are required to enforce the IEPA’s cross connection control regulations and requirements to prevent backflow contamination of the public water supply.

The purpose is to identify any potential cross connections that might exist at each property. A cross-connection is a plumbing interconnection between two water systems which allows, or could potentially allow water flow in either direction. A cross connection, without proper protection, could allow water of questionable quality to enter the public water supply. Some examples of potential cross connections include lawn irrigation systems, fire sprinkler systems, boiler heating systems, industrial or diagnostic equipment connected to the water supply or simply an unattended garden hose left in a bucket. Should pressure in the public water system suddenly decrease, there is the potential for untreated, contaminated or non-potable water to be suctioned into the public system. The result could be illness or injury should the contaminated water be ingested or come into contact with skin.

Common Residential Systems that require a device:

Lawn irrigation system

Fire sprinkler system

Swimming pool direct connection

Common Commercial Systems that require a device:

Lawn irrigation system

Fire sprinkler system

Boiler heat system

Dental equipment connected to the public water supply

Medical equipment connected to the public water supply

Industrial or process equipment connected to the public water supply

Cleaning or sanitation equipment connected to the public water supply

Cross connection control devices are required by the IEPA to be tested and certified annually. IEPA regulations require the testing and certification be completed by a State of Illinois licensed plumber, certified with the IEPA as a “Cross Connection Control Device Inspector” (CCCDI). The plumber’s name, license number and the state issued CCCDI number are required on the form before submitting to the Township.

Once the form(s) have been completed, please be sure a copy is kept for your files before submitting them to the Township. The IEPA requires a record of the cross connection prevention device tests and maintenance records be kept on the water consumer’s premises.

Township code requires the water consumer’s premises to be available at reasonable times to the Director of sewer and Water or his authorized agent, for the verification of information submitted by the water customer regarding survey information and cross-connection inspection results. To intentionally falsify or withhold information is a violation of State and/or Federal law. Cross connection control device tests and inspections must be performed annually. The Township will notify customers when a device requires annual testing, or a survey/inspection is due in accordance with State law.

If you have any questions or need assistance regarding the cross-connections control program, please contact the water department at (847) 455-8616. Thank you in advance for your cooperation.
