Lyttelton Harbour Wastewater Project

Kia ora from the Lyttelton Harbour Wastewater Project team.

We're hard at work in Lyttelton building the new Simeon Quay pump station. We're also busy across the hill in Heathcote and Woolston, laying the underground pipeline for the final stage of this project.

Thank you all for your patience as we work towards ending the routine discharge of treated wastewater into Lyttelton Harbour.

This project is part of our commitment to the Whaka-Ora Healthy Harbour Plan to improve water quality in Lyttelton Harbour, for current and future generations to enjoy.

Commissioning the Governor's Bay pump station

Lyttelton Harbour is a step closer to being a healthier place to swim and fish since the routine discharge of treated wastewater from Governor’s Bay has ended.
A brand new pump station is now pumping all of Governor’s Bay’s treated wastewater through a new submarine pipeline to Lyttelton.
From here, it’s being treated temporarily at the Cashin Quay pump station until the $53 million Lyttelton Harbour Wastewater Project is completed early next year. Read more on Newsline.

Building the Simeon Quay Pump Station

At our Simeon Quay site, we've finished excavating a wet well over 5 metres deep and are now preparing the structure to make it safe to work in – this includes rock bolting and shotcrete (sprayed concrete).

We will start building the reinforced concrete walls for the wet well in the middle of May and expect this to take just over a month to complete.

In the following few months, we will finish the wet well and start on infrastructure such as drainage and piping.

Over the coming months, this site will transformed into a new pump station, the powerhouse which will pump Lyttelton Harbour’s wastewater through an existing pipeline along Lyttelton Tunnel to connect with the new Heathcote Valley Pipeline.

An update on the Heathcote Valley Pipeline

We’re on track with installing the underground pipeline that will run through Heathcote to connect Lyttelton Harbour’s wastewater with the existing pump station in Alport Place in Woolston.

Last month our contractors were busy checking for existing services in Alport Place, Mauger Dr and the paddocks alongside Tunnel Road and Scruttons Road.

These investigations works are now complete and we've already laid almost two kilometres of pipeline through the paddocks parallel to Tunnel road, starting at the Ferry road side and working towards Scrutton’s road.

We've now started installing the underground pipeline along Scruttons Road between the paddock and the railway line.

Next, we’ll be opening up sections of the road, starting from Port Hills Road and working along Mauger Drive to Scruttons Road.

These works will be completed in sections with work on Mauger Drive due to start next week.

Multiple construction crews are working on the project to ensure minimum time on the road and disruption to residents.

You will be able to access homes and businesses unless advised otherwise and “start work” notices will be delivered before the construction crews are on-site.

Laying the Heathcote Valley Pipeline

This is the route of the underground pipeline that will run through Heathcote Valley to the pump station in Alport Place in Woolston. 

This work will have some impact on traffic but our contractors Fulton Hogan will be doing their best to minimise the disruptions and sharing regular updates with residents as the project progresses.

You can also find more information about works happening in your area on the Council website.

We appreciate your patience and thank you for your understanding while we build this fourth and final part of the new wastewater system.
