Wastewater treatment plant fire - Q & As

The 1 November fire at the Christchurch Wastewater Treatment Plant was one of the biggest in the city for several years and its impacts could be felt for a long time.

We've published a Newsline article where we answer some of your questions around our progress, how the plant is now operating, and next steps.

First aerator installed

We have installed the first aerator on the oxidation pond as a trial to see if the oxygen that it pumps through the water can help decrease the odour levels.

We're monitoring the results closely. If the trial is successful we plan to place more aerators in the first oxidation pond, and stop treating the water with hydrogen peroxide - a compound that naturally breaks down into water and oxygen - before it's discharged into the ponds.
