The new wastewater rising main that has been snaking up Onerahi Road, appearing and disappearing along with large mounds of dirt, orange cones and signs, is now complete.

Last week the project’s road markings and signs started to disappear, replaced with freshly grassed road verges, and on Thursday, the new pipe was connected up to the City’s main wastewater network.
The 1,100m long, 560mm diameter polyethylene pipe runs from the Waverly Street Pump Station, along Waverly Street and up Onerahi Road to the top of the hill. It was installed by drilling at some sections and digging open trenches at others. The lead contractor on the $900,000 project was United Civil Construction Limited (UCCL).
The new main replaces the old PVC pipe which had begun to fail through age and wear and tear.
Waste and Drainage Engineer Casper Kandori said the replacement pipe is bigger than the original PVC pipe, and this will allow an increasing quantity of wastewater to be transported to Whangarei’s main Wastewater Treatment Plant at Kioreroa Road as the population at Whangarei Heads increases. Over the coming week all holes will be covered and the footpath will be reinstated.
“Residents were very patient during the project this took longer than expected because of the storms this winter,” Mr Kandori said.
