Alert Level 3
This project is critical and will be restarting in Alert Level 3. All necessary safety precautions will be taken, including the use of PPE.
Construction is due to be completed in November, 2021.
Update 15 June 2021
The rising main upgrade on Bowen St continues to progress well, hitting some big project milestones and with some exciting work about to start.
Our team on site have now successfully completed work on the section of rising main on Bowen St to the west of The Terrace. At the same time we have installed a new gravity wastewater main to service the new developments at 40 and 44 Bowen St. By completing this work concurrently with the rising main project we have reduced the overall disruption in this part of the city.
Over the next week crews plan to demobilise from the current site and set up two new sites that will be in place for a couple of months and will allow us to substantially complete the project.
- The first site will be on Bowen St to the west of The Terrace where the new rising main will be connected into the main trunk wastewater main that flows to the treatment plant at Moa Point. We will be working in the middle two lanes with one traffic lane maintained in each direction throughout – the new site will be shorter than the existing one. This is a complex piece of work and most of it is going to take place underground. The site team will be working carefully to ensure that this job is completed to a high standard and the existing infrastructure is protected throughout.
- The second site will be on Bowen St between The Terrace and Lambton Quay. We will be working in the two middle lanes with one traffic lane maintained in each direction throughout. On this site we will be installing the final section of rising main that will connect to the sections that we have already installed under the Terrace and under Lambton Quay.
Update 9 April
Our team has now successfully completed work on a new watermain between Bowen Lane and Ballantrae Place. This watermain will improve the resilience of the network in this location and reduce the impact of future maintenance work on water supply.
We have also made a connection for the new wastewater main that is being installed to service the new developments at 40 and 4 Bowen Street. By completing this work concurrently with the rising main project we are aiming to reduce the overall disruption due to the work in this part of the city.
Our next piece of work will involve us establishing a long term closure of the two middle lanes of Bowen Street to continue the rising main, install the gravity main and make a connection to the main interceptor sewer that will carry the waste to the treatment plant at Moa Point. The closure will start the week of 12 April and remain in place for a few months. A single traffic lane will be maintained in each direction throughout the work but parking in the area will be affected. Traffic management will be in place.
We appreciate people's patience and understanding as we carry out this essential work, on behalf of Wellington City Council, constructing a new rising wastewater main for the Wellington CBD, from the Whitmore and Featherston intersection up Whitmore and Bowen Street to connect to the main interceptor sewer outside the Bowen Campus.
Update 22 February
Our work on Whitmore Street between Stout and Featherston streets is nearly completed.
This week we will be resurfacing the road then opening the lanes to traffic. To do this work safely we will be closing the lanes temporarily with vehicles detoured through Stout Street and back onto Featherston Street. Look out for this detour on Wednesday, Thursday and Friday this week (24-26 February) and follow the signs and instructions from our traffic management staff.
Meanwhile, our team in Bowen St are over halfway through installing a new watermain. The new pipe has been installed using trenchless drilling to try and reduce the amount of holes that we need to dig. This solution results in less disruption and a lower carbon footprint.
Over the next few days the team will reinstate at the intersection with Ballantrae Place and move onto the last drill shot in Bowen St.
This week we will also start work on the Bowen St section of the rising main project. Our team will be starting to work uphill from the Terrace intersection in a two lane closure. This activity has been extended to include a new wastewater connection for the Bowen Campus development. By combining these two projects we will be able to deliver more efficiently and achieve a better result for the city.
Update 19 January 2021
The project is progressing well and on track. Last year, we completed key sections of the project, through busy intersections at The Terrace, Lambton Quay and Stout Street.
This year, we will lay the rising main along Whitmore Street from Stout Street to Featherston Street where it will connect to the existing pump station. Once we have completed this work, the team will move onto Bowen Street.

Working with Wellington City Council, we have identified some additional work in Bowen Street that will be added into the project to improve efficiency:
The Bowen Lane Watermain – this is a section of watermain in Bowen Street to Ballantrae Place that needs to be installed to improve the resilience of the network.
Museum Street Wastewater Main – this is a section of wastewater main that needs to be installed in Bowen Street to allow for future development.
By taking a holistic view of these projects and bringing them together we are aiming to reduce the overall disruption to the local community.
While the road will remain open in both directions, to safely undertake this work, we will need to close some lanes in sections along Whitmore Street and Bowen Street. On-street parking alongside the worksite will be restricted.
The main construction work will generally be from 7am – 5pm Monday to Saturday. We will also be doing some night work between 5pm – 2am Monday to Saturday and for some parts of the project we will need to work during the weekend.

We appreciate everyone's understanding as we work to improve the city's infrastructure.
Update 23 December
The site will be closed from 23 December but we will be inspecting things regularly throughout the holiday period.
The project has made excellent progress since starting in the middle of the year, successfully completing the most tricky aspects of the project with crossings at The Terrace intersection and Lambton Quay as well as the section on Whitmore Street where the reclaimed land and tidal water table, which gave the team a real challenge.
A big part of success thus far the understanding of residents and businesses who live and work on the alignment and in the surrounding area. Thank you for your patience and for being part of our project.
The team will be returning to work on 5 January 2021, hoping to continue the success seen in 2020.
In the first couple of weeks, works will take advantage of the quieter traffic to pick up where work left off in the Stout Street intersection.
- This will mean that for approximately two weeks there will be no right turn available out of Stout Street onto Whitmore Street and no straight through manoeuvre towards Featherston Street. There will be signage and a diversion in place – please follow the signs.
- The southern pedestrian crossing of Whitmore Street will be closed but the Northern one will remain open.
Our team on site will be working hard to ensure that they efficiently clear this intersection.
2 December 2020
Last week we reinstated our trench at the Stout Street intersection and opened the lanes to traffic. This means that we have now successfully completed the new pipeline through the three major intersections on the project (crossing The Terrace, Lambton Quay and Stout Street). We now need to join up those crossings and make connections at each end.
Over the next few weeks – up to the Christmas break – we will be laying pipe between Stout Street and Lambton Quay with lanes closed on Whitmore Street. During this period there will not be any turn restrictions on Stout Street or Lambton Quay and all of the pedestrian crossings will remain open.
As ever – we are grateful for your patience and support while we undertake this critical work on behalf of Wellington Water and Wellington City Council.
Update 2 November
Crews have spent the last few days reinstating and tidying up the area on the harbour side of Lambton Quay, successfully completing work for the pipe ram at the Lambton Quay intersection, which was a critical aspect of the project. Along with the challenging section already installed ross the Terrace intersection, things are well set up to get into the trenched installation portion of the work.
In the first week of November we will be moving the site to install the rising main across the Stout St intersection.
This will mean that for approximately two weeks there will be no right turn available out of Stout St onto Whitmore St and no straight through manoeuvre towards Featherston St. There will be signage and a diversion in place – so please follow the signs.
One of the pedestrian crossings across Whitmore St will be closed at a time. Initially this will be the southern crossing and, and as the work progresses, we will change to the northern crossing.
Update 1 October
We have had a very productive couple of weeks in Whitmore St which has seen us ram a pipe 50m under the Lambton Quay intersection. Amazing to think that a critical piece of this project has now been installed underneath the ground without digging any holes in this busy intersection!
Traditionally this work would have involved at least four weeks' disruption to pedestrians and the travelling public in buses and cars in the middle of the intersection. As always we are grateful for everyone's patience during these essential works.
The next stage will be establishing a site in Bowen Street on the northern side of Lambton Quay to dig a receiving pit on the end of the newly installed pipe. This site is going to be fairly tight and it will be important that road users adhere to the speed limits and follow the instructions of our traffic management staff so that we can share the road and get to our destinations safely. Following this we will be able to insert the new rising main inside the casing that has been rammed through.
Update 21 September
With all the pipework now installed across the Terrace intersection, the team has spent the last week digging a 15m long, 4m deep launch pit from which we will ram a casing under the Lambton Quay intersection.
This should mean that no holes will need to be dug in the intersection itself, where traffic movements would make things difficult. Trenchless methods, such as pipe ramming, are a great way of reducing disruption to the travelling public, minimising some of the risks associated with digging holes in busy streets and keeping our carbon footprint to a minimum.
While the pipe ramming itself is a noisy activity, it will be kept to normal working hours with noise curtains erected to contain the noise as far as possible. This phase of the project is expected to be completed within the week.
Up in Bowen St our team has now installed all the pipework across the Terrace intersection and we will be backfilling and reinstating over the next few days. We hope to have closed up that site by the end of next week and have returned the road to its normal operating state.
Update 1 September
Progress has been good over the past couple of weeks and we have our first few lengths of pipe in the ground.
From the week beginning 31 August, we will be reinstating the road and pedestrian crossing and moving the site over to the eastern side of the Terrace intersection. This means that the right turn restriction from Bowen St into The Terrace will also be removed.
We have a few weeks' work to get across the remainder of the intersection and then the team will be moving into Whitmore St just south of Lambton Quay to tackle another critical part of the project.
As always, we thank everyone for their patience while we work to upgrade our Capital city's wastewater network.
Update 20 July 2020
Once work gets underway on Monday 10 August, there will be traffic disruptions for the duration of the project, expected to take six months. While the road will remain open in both directions, to safely undertake this work, we will need to permanently close some lanes in sections along Whitmore Street and Bowen Street. project.
Traffic management will be in place 24/7 and on-street parking in the area alongside the worksite will be restricted to accommodate this.
Work will start at the two key intersections with the Terrace and Lambton Quay. Due to the importance of the Lambton Quay/Bowen Street intersection, work in this area will be done by trenchless means to reduce the impact on buses and pedestrians in the area.

The main construction work will generally be from 7:00am – 5:00pm Monday to Saturday. We will also be undertaking nighttime work between 5:00pm – 2:00am Monday to Saturday. For specific aspects of the project, we will need to undertake some work during the weekend.
As always we apologise for any disruptions but hope people will be patient as we carry out this critical work investing in our city’s future. And we encourage drivers to avoid the area or travel at non-pe
We are constructing a new rising sewer main for the Wellington CBD.
The rising main (pipe which conveys sewage under pressure from a pumping station) will be constructed from the Whitmore and Featherston intersection up Whitmore and Bowen Street to connect to the main interceptor sewer outside the Bowen Campus. Some additional infrastructure upgrades needed in the area will also be incorporated. Starting in August 2020 the works are expected to be completed in July 2021.
