Working on sites with a recycled water service
Tuesday May 31 2016
For plumbers working on a site that has a recycled water service, knowing the source and nature of the water supply that you are working with is essential. The VBA encourages practitioners to undertake adequate steps to ensure that the risk of cross connection is minimised when working with existing recycled water systems.
Practitioners are reminded that all recycled water pipework, fittings and outlets must be correctly identified in accordance with the requirements in AS/NZS 3500.1 Plumbing and drainage – Part 1: Water services.
The VBA recognises that, for various reasons, existing recycled water systems are not always readily identifiable on-site. The most reliable way to identify the source is to turn off the supply to the property at the water meter. At the completion of the work, the water service must be tested for any cross-connection prior to commissioning.
Additional expectations for plumbing work completed at Victorian schools
For any plumbing work conducted on a water supply at a Victorian school (whether it be drinking water or recycled water) the plumbing practitioner is advised to undertake a cross connection check in all instances and to include relevant details on the compliance certificate demonstrating that a cross-connection check has been conducted.
