Cross Connection

In order to help better manage the health and safety of the potable water supply and deliver safe service levels to customers, the City has developed a cross connection control program. A Cross Connection Control Program protects the potable water supply from contaminants being introduced into the potable water system caused by back-siphonage or backpressure. Approved backflow prevention devices are necessary to protect the potable water from this contamination.

The intent of the Cross Connection Control Program is to:

  • Protect the public potable water supply within the City of Parksville from the possibility of contamination or pollution by isolating, within its customers internal distribution system, such as contaminates or pollutants which could backflow or back-siphon into the public water system.
  • Educate and promote the elimination or control of existing cross connections.
  • Provide for the maintenance of a continuing program of cross connection control which will effectively prevent the contamination or pollution of all potable water systems by cross connection.

The City of Parksville Cross Connection Bylaw No. 1320.11 (amendment to "Water Service System Bylaw, 1999, No. 1320") was developed to help the City identify and enforce cross connections or potential cross connections. Backflow assemblies must be a testable device. This device must be tested upon installation, after repairs and at least once every twelve months.

A backflow assembly test form must be completed and returned to the engineering and operations department.

All irrigation connections require a double check valve assembly (DCVA) and also must be tested upon installation. All new irrigation systems also require a permit available from City Hall at 100 Jensen Avenue East.

All devices must be approved by Canadian Standard CAN/CSA B64.10 (most current). Devices can be searched through the CSA International website at CSA Certified Product Listings. A backflow device not on this list will not be accepted.

British Columbia Water and Waste Association and Cross Connection Control
BC Water & Waste Association (BCWWA) is the recognized authority for the voluntary certification of backflow assembly testers in British Columbia and Yukon. Currently our cross connection control (CCC) membership consists of over 1,800 certified testers, certified inspectors and administration members.
