Two big infrastructure upgrades to essential water and wastewater services are getting under way in Rotorua this month.
The main 3.8km pipeline that carries about 1350 cubic metres of wastewater a day from Ngongotahā, through Parawai Rd, to Rotorua city’s network is being replaced, and the water main alongRanolf St is being upgraded.
Rotorua Lakes Council said the projects were part of its critical infrastructure renewals programme to “ensure the safety and reliability of water and wastewater services, reduce the risk of environmental and service disruption and enable future growth and development”.
Both projects would be undertaken in stages to minimise disruption, it said.
Sections of the Ngongotahā cycleway would be closed until November for the Parawai Rising Main wastewater replacement, which was being undertaken by Trility.
Once complete, the old pipe would be safely decommissioned, but would be kept to add future resilience.
The council said Goodrick Contracting would upgrade the water main along Ranolf St, between Malfroy Rd and Arawa St, in four stages starting this month.
It was expected to be finished by the middle of next year.
Residents would receive advance notice of any water shutdowns, access restrictions, or night work. The council and contractors would work to minimise disruption.
When asked about the cost, the council said the multimillion-dollar projects were commercially sensitive.
The staged closures of the Ngongotahā cycleway:
Stage 1: Frank St → Kawaha Point Rd, August 4 to September 1
Stage 2: Parawai → Frank St, August 11 to September 1
Stage 3: Parawai → Kawaha Point Rd, September 1 to November 30
