Destratification and Cyanobacterial Control

Ben Chifley Reservoir Project – Destratification and Cyanobacterial Control

ResMix 5000 CC

Ben Chifley Reservoir, 20km south east of Bathurst, is the primary water source for Bathurst and surrounds.

Bathurst Regional Council approached WEARS Australia to provide a solution for destratifying the water column and increasing concentrations of dissolved oxygen in order to reduce high levels of nutrients as well as eliminate the occurrence of seasonal turnover.

Other concerns included minimisation of toxic Cyanobacteria and replacing a highly inefficient and ineffective compressed air destratification system.

Challenges

Outcomes

The ResMix 5000 CC system successfully replaced the ineffectual air destratification system with operational costs at the reservoir reduced to approximately 15 percent of the previous budget.

Additionally, operators at the water treatment plant reported the use of disinfection chemicals had fallen to the lowest level in five years.

This represented a large financial saving for the Bathurst Regional Council.
