Water Remediation

Status update

Monday 18 September

Work is progressing at PCH to source and test suitable fittings to replace brass components, including those that are non-compliant, in the TMV assembly boxes.

This includes a thorough product scan across Australian and international markets to find the most suitable product to complete the remediation work.

This procurement activity is now focusing on newly developed components made of stainless steel and dezincification-resistant brass, as well as nickel-plated brass.

The decision to focus on these components follows extensive investigation of different replacement options for the existing brass fittings.

Potential suppliers of replacement components are being identified. The State is working with the industry and the Building Commission to determine design and procurement timelines, as well as to ensure that replacement products are watermarked and approved for use in Australia.

A trial and testing regime is underway, involving the decommissioning and recommissioning of TMV assembly boxes using alternate products. This process will take some time as all options are considered for suitability.

Remediation activities will be scheduled in priority clinical areas to ensure the hospital is opened as soon as it is safe to do so.
