Hawthorne Street, Walnut Avenue and Lansbury Avenue - wastewater main renewals

Update

What

We’re replacing the wastewater network under the roads and footpaths.

Why

The local wastewater network has reached the end of its serviceable design life and therefore is due for replacement.

Where

Hawthorne Street, Lansbury Avenue and Walnut Avenue, Fendalton.

When

10 November 2025 to late June 2026. Monday to Friday, 7am to 6pm (weather/site condition dependent).
(Note: some Saturdays may also be worked pending works progression over the scope)

Contact

The contractor is UINZ. Phone Ryan Thom on 027 236 4669 or email ryan@uinz.co.nz, Monday to Friday, 8am to 5pm.

Details

Works completed to Date (Stage 1 & 2 – Walnut Avenue and Hawthorne Street):

  • 210 meters of wastewater main installed.
  • 130 meters of wastewater laterals installed.
  • 4 new manholes installed.
  • Walnut Avenue pavement restoration completed.

Stage 3: Hawthorne Street & Lansbury Avenue

  • Works will start from the Lansbury Avenue/Hawthorne Street intersection and continue down Lansbury Avenue where a temporary road closure will be installed from 7am to 5:30pm, Monday to Friday, continuing for approximately 2 months as we work down all of Hawthorne Street (see full scope markup below). We ask that during the working hours listed that cars are parked outside of this area on Hawthorne Street. Pedestrian access to properties will be maintained at all times during working hours. Outside of working hours, vehicle access will be restored where safe to do so.
  • Please note that these works will occur simultaneously with contractors working on Hawthorne Street and are part of the same contracted scope to upgrade the wastewater network in your area. Carrying out the works together will aim to reduce the overall project programme by approximately 2 months.
  • Please let us know if you have any specific property requirements e.g. medical visits, home help, large vehicle deliveries, planned works etc. and we will do our best to make sure you are accommodated. 
  • If there is an emergency and you need to drive through the site during the working hours noted, please notify one of our crew on site and we will do our best to accommodate your access needs. If driving through the works area in such events, please ensure you are being directed by an appointed person on site at all times.

Further notifications

  • As the project progresses, we will do some additional letter drops to keep you informed of upcoming stages and any property access impacts as required.

Other details

The scope of works involves trenching 800 metres of a new wastewater main, including the install of new laterals that will form the new feed connecting to your property at your boundary. We will also be digging small potholes along the road, footpaths and berms to find the location of existing services. This potholing work involves a specialised equipment called a hydro-truck, which can be noisy. We apologise in advance for any inconvenience this may cause.

All this will involve pumping underground water, trenching and excavation works. At the end of this project, we will reinstate the section of road we’ve worked on with new asphalt. 

Our schedule will depend on the weather and the condition of the roads. We will provide updates if there are changes to the planned works.

We know this work is disruptive, and we appreciate your co-operation and understanding over this period.
