Unitec wastewater diversion project

Project overview

Watercare is installing a new wastewater connection at 125 Carrington Road and in the Oakley Creek Reserve, Mt Albert, near the Unitec Mt Albert Campus.

This work involves:

• Excavating for a connection to the Ōrākei Main Sewer (OMS).

• Constructing a satellite manhole and associated connecting pipe.

• Installing a section of 600mm diameter wastewater pipe using trenchless methods from the top of the embankment above the proposed trunk sewer connection beside Oakley Creek.

Why this project matters

The upgrade will help reduce wastewater overflows from the Carrington branch sewer and the OMS into Oakley Creek, while supporting the future development of the Unitec Precinct.

Supporting growth

The Unitec Carrington Road campus area is expected to undergo significant redevelopment, with around 4,000 new dwellings planned. This new infrastructure will ensure the network can handle increased demand and protect the local environment.

Timeline

Construction is scheduled to start in early 2026 and finish by mid-2026.

How will this affect you?

• Working hours – will be between 7am to 6pm Monday to Saturday. Saturday work will only be utilised if required.

• Access to the Oakley Creek walking track/waterfall from Unitec Campus – will remain open during these works. However, the walkway south of the upper bridge down the creek will be closed for periods during the works. Note that this part of the walkway is currently closed to through traffic due to another project fixing the lower bridge. Signage will be in place.

• Construction works – will create noise, vibration, and dust. We will endeavour to keep disruption to a minimum and will be working in accordance with the levels under the Auckland Unitary Plan.
