Warning on dirty water
ANGLERS are recommended to stay away from West Rd Creek after a sign was erected for polluted waters.
The sign was placed on Tuesday, December 6, after a minor release form the wastewater treatment plant earlier that morning.
Southern Downs Regional Council manager of water and waste water Tendekai Mapeza said the release of the unchlorinated secondary treated wastewater came after something got stuck in a valve.
"A foreign body (piece of grit or stick) had passed through some protective screening and lodged in a float valve at the Stanthorpe wastewater treatment p;lant,” Mr Mapeza said.
"This blocked the valve open and allowed a minor spill of unchlorinated, secondary-treated waste- water to pass into the creek.”
The wastewater released had undergone secondary treatment and gone through the final stage of treatment.
Chlorine would have been added, to disinfect the water, before its release as Class B recycled water which is used to irrigate sporting fields and other public places, as well as by irrigators on crops. Currently the water is flowing well and, at the time of publication, had not impacted the ecosystems in or around the creek.
"There have been no signs of any fish kill or other indications that the riparian ecosystem has been negatively impacted by the release,” Mr Mapeza said.
Stanthorpe Blue Water Fishing and Restocking Club treasurer Ernie Jones said people should report any dead fish.
"If they see any signs of dead fish, immediately notify the council,” he said.
Mr Jones also said due to the spill being a minor risk, there was nothing to worry about but he recommended steering clear until the signs were removed.
"Don't fish until the signs have been removed and don't swim,” he said.
Water samples, which have been sent for testing, are expected to return this week.
