Boundary Backflow Code of Practice Pathway to Excellence

Annual Conference

The second edition of BBCOP was requested by Water NZ Water Managers Group to clarify the Health (drinking water) Amendment Act October 2007 to be able to use it as a model for policy statement and bylaws.

This paper covers guidelines for water suppliers to develop Safety Plans for Backflow Protection using risk assessment to determine the level of backflow protection required.

The ownership of boundary devices is discussed with varied options available to the Water Supplier depending on their Councils policy.

A. Water Supplier owned

B. Customer owned

C. Combined ownership

A Backflow Prevention Programme should be developed:

  • That starts with identifying potential risks by means of inspection
  • Ensure all boundary devices are tested annually
  • Installation/replacement programme for non-testable dual checks
  • Water tankers
  • Public awareness response team

The Code of Practice for Backflow is then covered highlighting the Water Suppliers responsibilities for various devices, testing requirements, and additional requirements for fire systems.

Responsibilities of the Water Supplier, Property Owner and Testers are clarified and clearly laid out ensuring the Backflow Safety Plans are robust. From inspected hazards, installation of devices, annual testing and recording of incidents are all required for inspection and proving the Safety Plan is working to the satisfaction of the Water Assessors appointed by the Ministry of Health and employed by the Local District Health Board.
