The Mt Crosby East Bank and West Bank Water Treatment Plants, which produce about 50 per cent of the region’s water supply, have been operating at reduced capacity since Saturday.

The impact to water treatment production at the plants was due to flood waters washing soil and debris into the waterway that the plants draw water from.

Seqwater’s Operations Team has been working around-the-clock to progressively bring the plant back to full production, with South East Queensland residents asked to temporarily reduce water use to help manage supply as a precaution.

Seqwater Chief Operating Officer Stuart Cassie said the treatment plants were now almost back to normal operations, which meant water reduction measures were no longer required.

“I would like to thank the community and our service partners, Urban Utilities and Logan Water for their support as our teams worked to get these vital assets back up and running as soon as possible,” Mr Cassie said.

Mr Cassie said water treated from the Gold Coast Desalination Plant had been transported via The SEQ Water Grid, to manage supply while the plants operated at reduced capacity.

“This is an example of the importance of assets like the SEQ Water Grid and the Desalination Plant in ensuring water security for our region, not only in drought situations but also during supply disruptions at our conventional treatment plants.
