Seqwater has reversed the flow of water in stage 1 of the Northern Pipeline Interconnector (NPI) to ensure continuous supply to the Sunshine Coast as the Landers Shute Water Treatment Plant is upgraded.
The Sunshine Coast’s drinking water supply is being supplemented from North Pine Dam, near Petrie in Brisbane.
The reversal will ensure supply to the Sunshine Coast while the Landers Shute Water Treatment Plant, near Montville, undergoes an upgrade to improve the long term reliability of this critical component of South East Queensland’s Water Grid.
Seqwater Chief Executive Officer, Peter Dennis, said reversing the NPI to supplement the Sunshine Coast supply from outside the region demonstrated the benefit of the water grid.
“Our water grid allows us to move water around South East Queensland to where it’s most needed,” Mr Dennis said.
“Changing the flow direction of bulk water supply pipelines is part of normal operations at Seqwater to best manage water supply levels and keep the grid operating efficiently.
“Some water will still be sourced from Baroon Pocket Dam to the Landers Shute Water Treatment Plant to maintain supply to Sunshine Coast, but at a reduced amount to allow us to work at the water treatment plant.”
Mr Dennis said the NPI can transport up to 65ML of treated potable water a day from Brisbane to the Sunshine Coast or in the other way.
“In the next couple of days, some parts of the Sunshine Coast and Moreton Bay Regional Council area will receive water from the North Pine Water Treatment Plant, which sources its water from the North Pine Dam. Suburbs include Morayfield, Elimbah, Nambour, Noosa, Image Flat, Caloundra and Caboolture,” Mr Dennis said.
“People may notice a slight change in their drinking water as different water sources have their own characteristics.
“Regardless of the source, our water continues to meet the strict health requirements of the Australian Drinking Water Guidelines 2011.”
