Timor Dam Project – Cyanobacterial Bloom Control
Timor Dam, which is the sole potable water supply for Coonabarabran and surrounds, had a history of toxic cyanobacterial outbreaks.
At several times the storage was forced to shut down as a result of more severe algal blooms and often treatment with powdered activated carbon was required to eliminate taste and odour concerns. A compressed air system at Timor Dam was costly, inefficient and proved ineffective at circulating the storage and overcoming issues caused by anoxic water.
WEARS installed a ResMix 3000 system in 1999. This has recently been upgraded (Dec 2016) to a new and improved system that guarantees high water quality for at least another 20 years and can cope with any future plans to increase the storage size.
