Floods prompt shire to seek Kambalda rock walls funding

Thursday January 30, 2014 - 14:52 EDT

The Coolgardie Shire says Western Australian Government funding is needed to fast-track the construction of several rock walls to protect Kambalda from flooding.

Last week, the Goldfields' town was hit by torrential rain, flooding 18 houses with water up to two metres high and currents washing away two bitumen roads.

President Malcolm Cullen says one and a half of four rock walls has been completed and without additional state funding it will take another two years to complete.

Mr Cullen says the rock walls should ensure water overflowing from the catchment does not flow "like a tidal wave".

"We believe that it should slow the rate to something that is controllable and will allow the water to travel through the town at a controlled rate which then should not flood all these houses," he said.

"Because it's constructed out of rock with no dirt, as the water builds up on the wall it's like a slow release of the water, so that it doesn't come down in like a tidal wave, so that each wall would contain a certain amount of water and as it went through that wall it'd build up on the next wall to the next wall, so that by the time it actually approaches the town, it would basically be a controlled flow of water.

"Those houses are always going to be in the firing line of any above average rainfall event, until we can actually design a new drain or a bypass for the water to go around those houses."
