Huia water treatment plant sludge dewatering upgrades

We are undertaking upgrades to the sludge dewatering process at the Huia water treatment plant. A powdered activated carbon dosing unit will also be installed to improve process reliability and operability.

These works are part of the normal plant operation and maintenance upgrades and are not part of the Huia water treatment plant replacement project.
