Cross Connection Control Program

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 Control Bylaw No. 1529 was developed to help the City identify and enforce cross connections or potential cross connections. Testable backflow assemblies must be tested upon installation, after repairs and at least once every twelve months. Test reports shall be sent to the City within thirty days of completion. The City of Parksville will provide blank copies of test reports and display tags upon request. All works, including survey, testing, replacement or upgrades must be performed by an individual certified by the BC Water and Waste Association. A backflow assembly test form must be completed and returned to the operations department.

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. Buildings and facilities that are considered to be of moderate or severe degree of hazard shall have a testable backflow prevention device installed and tested annually. See the following document to determine the degree of hazard of a particular facility.
