Cross-Connection Control Protection Program

The purpose of cross-connection inspection is to identify and evaluate potential cross connections in a water supply system and to ensure that appropriate cross-connection control measures are in place to prevent contamination of the potable water supply.

The importance of cross connection control lies in the fact that it helps to prevent the contamination of our drinking water. Cross connections can introduce harmful bacteria, chemicals, and other contaminants into the water supply, which can lead to serious health problems for those who drink the water.

A cross connection occurs when a plumbing system or other water system is connected to a source of non-potable water or a contaminant. This can occur when there is a backflow of water due to a change in pressure, such as when a water main breaks or when a fire hydrant is used.

Cross-connection inspection is conducted by certified members of the Water Department who are trained to identify potential cross-connections, assess the risk of contamination, and recommend appropriate control measures. These inspections are essential for ensuring that the water supply system is safe and meets regulatory requirements of the CTDPH.

The primary objectives of cross-connection inspection are:

  1. Identify potential cross-connections: Cross-connection inspectors identify all potential cross-connections in a water supply system, including both actual and potential cross-connections.

  2. Evaluate risk of contamination: Once the potential cross-connections are identified, the inspectors evaluate the risk of contamination associated with each connection. This helps to prioritize the control measures that need to be implemented.

  3. Recommend appropriate control measures: Based on the risk assessment, the inspectors recommend appropriate control measures to prevent contamination. This may include installation of backflow prevention devices, regular testing and maintenance of backflow prevention devices, or changes to plumbing or water supply system design.

  4. Ensure compliance with regulations: Cross-connection inspections are typically required by law, and the inspectors ensure that the water supply system is in compliance with all applicable regulations.

Overall, cross connection control is an essential aspect of protecting public health and ensuring that our water supply is safe to drink. By taking proactive measures to prevent cross connections, we can help to minimize the risk of contamination and keep our community healthy and safe.
