Barkers have completed armouring banks works at the Waipukurau wastewater treatment pond and will be starting remediation works on the Waipawa wastewater treatment pond in mid-February.

The team is making good progress, our contractor, Barkers, have excavated around the Waipukurau pond - they have laid 350m of geotextile cloth and poured about 250m of the 600m of concrete around the perimeter. They will be installing pads strategically around the pond, making it safer for the operators to access the pond while conducting sampling of the wastewater.
