Aerators surge to life at wastewater
treatment plant

Eight new aerators have been turned on at the fire-damaged Christchurch Wastewater Treatment Plant as the Council’s mid-term recovery plan to address one of the two sources of unpleasant odours reaches its next phase.

The Council has converted two of the plant’s clarifier tanks into aeration basins in an effort to improve the quality of the effluent being pumped into the oxidation ponds

Here are some more photos of the aerators in action, showing how much they agitate the water. Note that this water agitation won't increase the amount of odours coming from the wastewater treatment plant. Two of the four clarifier tanks at the plant have been converted to aeration basins, and there are now four aerators operating in each basin. 

We took this image below last month as the aerators were being installed. It's a good depiction of how big each of the eight aerators are.
