LATEST: PREMIER Campbell Newman has urged Greater Brisbane residents to conserve water, after the Mt Crosby Water Treatment Plant shut down on Tuesday.
Premier Newman told residents to limit water usage to "drinking, cooking and bathing."
The Mt Crosby plant went offline on Tuesday morning due to record turbidity.
Seqwater chief executive Terri Benson said turbidity levels in the Brisbane River on Tuesday were four times worse than the January 2011 floods.
Ms Benson said Seqwater expected the turbidity issues would take up to 48 hours to dissipate.
Water may taste different, but is safe to drink, Premier Newman advised.
Mt Crosby is the region's largest water treatment plant and supplies the majority of drinking water to the Brisbane, Ipswich and Logan council areas.
Major water treatment plan hit by flooding
1PM: THE MT Crosby Water Treatment Plant is offline, and Seqwater CEO Terri Benson has urged south-east Queenslanders to conserve water.
"Due to record turbidity levels in the Brisbane River as a result of the extreme weather from ex Tropical Cyclone Oswald, the Mt Crosby Water Treatment Plant is currently offline," Ms Benson said.
Seqwater was currently meeting the bulk water supply demand across the region, Ms Benson advised.
However, residents in the Ipswich, Lockyer, Somerset and Scenic Rim regions, as well as in Brisbane, Logan, Redlands and Moreton Bay, should conserve water over the next 24 to 48 hours, while water supplies are replenished, Seqwater advised.
Ms Benson said the the turbidity levels in the Brisbane River were four times the level experienced during the January 2011 flood event and are expected to take up to 48 hours to dissipate.
Mt Crosby is the region's largest water treatment plant and supplies the majority of Brisbane, Ipswich and Logan city council's drinking water.
While the Mt Crosby plant is offline, Seqwater will use the Water Grid to move water from a number of different bulk water sources across the region, including the Gold Coast Desalination Plant.
Ms Benson said some water sources were experiencing high levels of manganese, due to the large flows entering the water sources.
"Manganese is a naturally occurring mineral and customers may notice discolouration and odour," Ms Benson said.
Manganese can also stain plumbing fixtures and laundry.
