UPDATE 5/12/2019 4:54 PM

 
The western end of Dixon St (from the intersection at Willis St) until MacDonald Cres is closed until further notice. Access to MacDonald Cres via The Terrace is still available.
 
As part of our works to repair the wastewater leak, our team came across a collapsed section of pipe which requires urgent repair. This resulted in immediate road closure, meaning we couldn't advise the public earlier.
 
As a part of this urgent work, a pumping truck will be on site. We will aim to keep noise down, however we expect the truck to run until 7pm.
 
We are working with affected residents and businesses to keep them updated on any increased noise.
 
We will provide an update tomorrow on the status of the road closure.

UPDATE 5/12/2019

As part of our works to repair the wastewater leak at the intersection of Willis St and Dixon St, we need to close the western side of Dixon St.

We have found an issue that we need to investigate which requires closure of this section of the road.

We will provide an update later this afternoon.

UPDATE 28/11/2019

As part of the recent sewer works on Willis Street/Dixon Street, a water leak was identified. We will be completing this repair tonight between 11pm-3am, this will involve water being shut off. Water is expected to be back on at 3am, however if there are any delays we will notify Wellington City Council who will share this information on their social channels.
 
Noise will be minimal, and affected businesses/residents have been informed.

Full traffic flow will be maintained through the intersection, with existing traffic management in place due to the closed shoulder on the Northern Western corner of the Dixon/Willis Street intersection.


UPDATE 27/11/2019

On Saturday we contained the sewer leak by diverting it out of the stormwater network back into the wastewater network. 

Test results on the harbour quality from Sunday came back confirming the water was safe for swimming. We are taking down the warning signs this afternoon, and the Greater Wellington Regional Council's 'Is it safe to swim?' the LAWA 'Can I swim here?' maps will also be updated.

Crews are continuing works to investigate and repair the leak which is expected to continue throughout this week, with the potential to continue into next week depending on investigations.

We will share an update on the expected time frame around the works on Friday 29 November.

Please follow the stop/go traffic management, or avoid this route if possible.

UPDATE 20/11/2019 

We have narrowed down the location of the issue to a 10m long concrete chamber at the Northern/Western corner of the Dixon Street/Willis Street intersection and will continue carrying out investigations to understand the extent of the issue. From this investigation we will form a construction plan to repair the concrete chamber.

We expect these works to continue throughout the day from 9am-4pm, for at least the next week. We will continue with the current traffic management, however any changes to the works area may alter traffic management. This will be advised if the case.

The leak is still affecting the inner Wellington Harbour, so we continue to warn people to stay out of the inner harbour specifically in the Whairepo Lagoon. We are continuing to update affected residents and businesses on the situation, and will update our website and social channels as more information comes to light.

We currently have stop go traffic management in place on the intersection of Willis St and Dixon St, due to a leak in a pressurised sewer.  We are looking at the best way to excavate and repair this leak safely, and will keep you updated on any traffic management changes.

As a precaution we have put up signs at Wellington Harbour advising people not to swim due to possible contamination. We are carrying out testing in the Harbour and will advise of the results.
