New system for managing backflow devices

A new system has been introduced around backflow devices designed to keep our freshwater system safe and clean.

Backflow devices are installed in the water pipe between Council’s water supply system and the privately-owned water pipes on individual properties.

The spring-loaded valve device ensures water can travel in only one direction through the pipes and that contaminated water cannot be sucked back into the water supply when the pressure in the water supply drops.

A good example of this kind of situation is a swimming pool complex where swimming water is treated with chemicals. It is very important to have systems and equipment in place to ensure the treated water does not get sucked back into the main water supply.

In the past Council contractors have tested the devices each year, charged the people who use them for the testing and required customers to take care of repairs by professionals.

Customers frequently suggested that it would be simpler and more cost effective if the contractor carried out any repairs and re-tests on site when faults were identified. As a result Council has reviewed its boundary backflow prevention policy, agreed that the suggestion makes good sense and has changed its policy.

To do things the way customers have requested does require Council to take up ownership of the backflow prevention devices.

This has been arranged through a bylaw change, but people who do not want Council to take ownership of their devices can opt out of the new system by contacting Council and making arrangements to take care of authorised testing and maintenance themselves.
