Project summary

What we're doing

Work is under way by CB Civil to build two new wastewater pipelines to connect Peacocke ​ with Hamilton’s existing wastewater network.

The 5.5km pipes will run from Cobham Drive (SH1), along the East Town Belt and Wairere Drive and connect to the existing wastewater network near Crosby Road. The pipeline will eventually link up with a new pump station to be built in Peacocke.

We're using a combination of open trenching and directional drilling to build the pipeline.

  • Open trenching involves digging a channel and laying the pipe inside it. This will be used along the East Green Belt and alongside roads.
  • Directional drilling involves using a drilling machine to push and pull the pipes underneath the ground. This will be used where digging a trench would be too disruptive,
  • like crossing major roads and train lines.

Work began in November 2020 at East Town Belt (Flynn Park to Marist Park), then on to Ruakura (Ruakura Road to Tramway Road) and Tramway Road (south of Fifth Avenue). The final stage of work is happening in the Wairere Drive area (Tramway Road to Carrs Road) in early 2022.

In the final stage of the project, work is being done in the East Town Belt parks – Flynn, Clyde, Lugtons and Marist – to restore grass and complete replanting in areas where the pipeline has been installed.

Why we're doing it

As we build our new community in Peacocke we need to make sure we put the right infrastructure in place at the right time, like pipes for our wastewater.

This project will

  • Provide essential wastewater services to Peaccoke

  • Connect to the new wastewater transfer station in Peacocke

  • Enable development of Peacocke to proceed

Project features

  • Northern wastewater pipeline feature 2

    325 litres per second

    Together these two new pipes can move up to 325L of wastewater per second - the same as filling one paddling pool every second.
  • Northern wastewater pipeline feature 1

    1090 tonnes of CO2 saved

    We estimate 1,090 metric tonnes of CO2 was prevented from being emitted due to the material recycling method used during construction. That’s equivalent to emissions from 350 cars in the same period.
  • Northern wastewater pipeline feature 3

    Restored green spaces

    We’re restoring grassed areas and replanting areas where the pipeline has been installed.

Where we're at with progress

  • Stage 1 - Planning

    2020

    As we build our new community in Peacocke we need to make sure we put the right infrastructure in place at the right time, like pipes for our wastewater.
  • Stage 2 - Underway

    November 2021

    Work to install the pipeline began at the East Town Belt. The work is being done in stages, with each stage taking two to three months to complete.
  • Stage 3 - Completed

    June 2022

    Construction will end at Wairere Drive, finishing with the restoration of grassed areas and complete replanting in areas where the pipeline's been installed.

Frequently asked questions

What is the cost of the new pipeline and where is the funding coming from?

The $28.5 million project includes two pipelines running from Cobham Drive, along the Eastern Town Belt and Wairere Drive to connect into the existing wastewater system near Crosby Road. The project was made possible with the support from the Government’s Housing Infrastructure Fund, made up of a $180.3 million 10-year interest-free loan.
