Penetanguishene's Cross-Connection Control Program

The Cross-Connection Control Program (CCCP) was created to protect Penetanguishene's water distribution system from the backflow of contaminants into the system.

The Cross Connection Control Program exists to ensure that proper backflow prevention devices are installed and working to prevent contamination of our drinking water.

What is Backflow?

Water normally flows in one direction from the public water system through the customer's cold or hot water plumbing. If the water begins to flow in the opposite direction, due to back pressure or back siphonage, it can become contaminated from cross connection. Backflow can occur in any residential, commercial or industrial property.

Backflow from back siphonage is caused by a negative or sub-atmospheric pressure; a drop in the water main pressure. Events that can cause back siphonage include a water main break or a high rate of water withdrawal, such as firefighting.

Backflow from back pressure is caused when the water system is connected to a system or supply operating at a higher pressure than the municipal water system. A booster pump or elevated piping are examples of connections that operate at a higher pressure that cause back pressure.

Installing a backflow prevention device at the point where the water service enters a building or facility will ensure that Penetanguishene's water distribution system is protected from contamination.

Purpose of the Program

Penetanguishene chose to take a proactive approach to backflow prevention and cross-connection control and established the Cross-Connection Control Program (CCCP).

This program:

  • Monitors compliance of the Cross-Connection Control By-Law.
  • Identifies cross-connections where potential contamination of potable (drinking) water may occur.
  • Enforces the required installation of suitable backflow prevention devices.
  • Maintains a database of Authorized OWWA Accredited testers.
  • Maintains a database of locations that have backflow prevention devices installed.
  • Ensures testing of installed devices on a yearly basis.
