A water main has been washed away at Goodna overnight.
The pipe which crosses Woogaroo Creek 1km south of the Ipswich Motorway at Edna Street was smashed by floodwaters at the height of last night's peak flooding.
Local Councillor Paul Tully inspected the scene at first light and said council tankers were on the way to provide emergency water supplies to affected residents.
"Water is not expected to be restored until midday at the earliest," Cr Tully said.
