Wellington Water advises that the biofilter media replacement works at the Seaview Treatment Plant have been completed ahead of schedule.

The works were initially expected to be completed in late January, but the project team managed to reinstate the biofilter media prior to the Christmas break.

“The team have made excellent progress during December, all the six cells of biofilter media are replaced and now commissioned,” says Jeremy McKibbin, Wellington Water GM Network Management.

While the biofilter media has been replaced, it will take a short period of time to bed in and become fully functional and 100 percent effective.

These works are a small first step to improve odour management, Hutt City Council has also included $13 million of proposed upgrades and improvements in the draft Long Term Plan.

This investment will support the long-term solution to odour management at the treatment plan.

Hutt City Council Mayor Campbell Barry said he’s happy with the progress made by Wellington Water to get the biofilters installed.

“Addressing the odour is a priority for us and we’re pleased this part of the process is now done.

“We know it will take some time for the biofilters to bed in but we’re confident it will help with the odour issue, along with bringing forward other projects as part of our next Long-Term Plan.

“Thank you to everyone for their patience. We know the odour has been unpleasant and stressful for residents and businesses,” says Mayor Barry.
