Around 4 billion litres of drinking water is estimated to have been saved in Metropolitan Wellington.
Around 4 billion litres of water saved thanks to a massive reduction in leaks across the public water network

New figures show daily water loss has dropped by 11 million litres per day – that's four Olympic swimming pools saved every single day, or the daily water use of around 50,000 people. Read more

Latest Updates

9 July 2025 Victoria Street & Mercer Street intersection closed from July 14 - July 21

The renewal works in Victoria Street started in early July 2025 and are connected to the projects on Taranaki and Wakefield Streets, which have recently been completed.

After works are completed, it will enable more efficient maintenance of the CBD wastewater network with capacity for wastewater to be diverted or stored rather than bursting and overflowing onto the street.

Where possible, we have coordinated the work with other Wellington City Council projects in the area to minimise disruption on people and businesses. 

Why are we doing this?

This project is part of a major upgrade of the CBD wastewater network. The upgrade is designed to ensure future resilience, support population growth and protect the environment.

Wakefield Street Rising Main - Stage 1

What we are doing

We're replacing an existing rising main along Victoria Street that has reached the end of its life. A rising main is a pipe that moves wastewater under pressure - so that it can travel to the main pipe (the interceptor) and then to the Moa Point Wastewater Treatment Plant.

For Stage 1, we are working between the intersection with Willeston Street and the junction of Wakefield and Victoria Streets - the slip lane from Victoria Street onto Wakefield Street.   

We have timed the work in this area for Stage 1 to avoid delays to the work that is being undertaken to strengthen Te Matapihi/the Central Library.  The second stage between Harris and Willeston Street will be constructed following this work. 

 

All Updates

9 July 2025 Victoria Street & Mercer Street intersection closed from July 14 - July 21

Works to to connect the Victoria Street and Wakefield Street sections of the new CBD wastewater pipeline are underway.
While there are no planned water outages during the works, traffic management will be in place.

  • Mercer Street will be closed to all vehicles. Vehicles travelling south on Victoria Street will need to detour into Harris Street. The westbound lane of Harris Street will be closed except to residents.
  • On-street parking in the area around the worksite will be restricted due to traffic management. Resident and tenant access to parking basements at Aon Centre and 62 Victoria Street will be maintained by the traffic management team.
  • Pedestrian access will be unaffected - crews will direct you around the works area.
  • Works will take place from Monday to Friday between 7 am and 6 pm

Thank you again for your patience. These works will improve the capacity and resilience of the CBD’s wastewater network, minimising the risk of bursts or overflows, and wastewater being discharged into the harbour.
