Newcastle Water Supply Upgrades

As a Council, we're making sure we can provide essential water services for Hamiltonians now and in the future. To better manage the water supply in the Dinsdale area, we'll be installing new water pipes and upgrading the water pump station on Newcastle Road.

The Newcastle Water Supply Upgrades is a construction project that Hamilton City Council is working on with our contractor, Waipa Civil. This project will allow us to better manage the water supply, detect leaks and ensure a consistent water supply for Hamiltonians now and in the future.

This is a $16.5M project funded in the 2018-2028 Long Term Plan.

A number of streets will be affected by the work, which will be done in stages between September 2021 and December 2022.

The works will consist of constructing and installing watermains (pipelines) around the Dinsdale area. In the first instance, this is down a 500-metre section of Newcastle Road.

The nature of the work means night work will be necessary but access to properties will be maintained and our contractors will be working hard to minimise disruptions. Most of the work will take place on the side of the road but at times will be in the roadway, traffic management will be in place and road users should expect delays.

Next year, as part of the wider project we will be starting to work around other parts of Dinsdale. We will circulate more information – including letter drops, ad campaigns and an update to this page – a bit closer to the time with more information on when and where those works are going to take place.


  • We are flattening the Maple Ave roundabout to allow for a bus detour route. This is scheduled for 16-19 September, as preparation work for the next phases of the project.
  • The first stage of pipe works will commence on the 27 September, where we are partially closing a section of Newcastle Road for the upgrades. This section is from 67-133 Newcastle Road, and the closure will be in place for approximately six weeks.
  • After this initial phase, we will be working on other parts of Newcastle Road towards Whatawhata Road, with a small section of pipe installed at The Dales (off Newcastle Road). This is as far as the works will extend this year.


If I live in the area, can I still access my property?
Residents will continue to have full access to their properties, and footpaths will continue to provide pedestrian access during this time.

Do I need a 'pass' to access my property?
There will be no 'passes' or proof of residence required for residents to access their properties by vehicle, but there is residents only stipulation on the signage, with clearly marked detours to direct commuters and other non-local traffic. Please note we will have temporary traffic management set up at all work sites which will be fully monitored and audited to ensure it is safe.

Will there be any disruptions?
Our contractors are working to minimise noise and other disruptions to residents and others in the community.

Are any bus routes in the area affected?
Bus routes will be affected by detours, meaning some services will temporarily change. For further information on those timetable and route changes, please refer to
