WASTEWATER LEAK - PROSSER STREET, TITAHI BAY
Wellington Water crews responding to a wastewater leak on Prosser Street, Titahi Bay

Our team have responded to a wastewater leak at the corner of Prosser Street and Titahi Bay Road. 

Excavation is currently underway. The pump station is operating but will need to be shutdown before repair. Plans to divert the wastewater flow away from the pipe is being developed as the pipe will also need to be shutdown before repair.

There has been an earlier discharge into the stormwater network. This has now stopped with sucker trucks managing the flow, preventing wastewater entering the stormwater network. Signage has been placed at the outlets into the harbour and water quality sampling will be underway.

Traffic management has been set up on Titahi Bay Road. One southbound lane has been closed.

14/11/25 Major upgrades completed at Willeston Street

In November our contractors wrapped up the works at Willeston and Victoria Streets, renewing the main wastewater pipe and connecting it to the pump station which drives wastewater from the CBD out to Moa Point Wastewater Treatment Plant.

On November 14th our contractors wrapped up the works at Willeston and Victoria Streets, renewing the main wastewater pipe and connecting it to the pump station which drives wastewater from the CBD out to Moa Point Wastewater Treatment Plant.

There will need to be some final bits of work done in the new year, and we do need to pop the hatch every now and then for routine maintenance, but this will involve much less disruption for pedestrians, drivers and local businesses.

What we are doing
