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.

Water Networks

Every year we carry out over 200 different projects in our four cities. These projects range from renewing a stormwater pipe in a single street to building a new reservoir.

Now that’s what we call a deep clean!

Constructed over twenty years ago to address stormwater flooding in the CBD, the Harris Street syphon sits 16 metres under ground level. It’s meant to drain stormwater from around Willis and Victoria Streets and discharge it, using its own momentum, at Frank Kitts Park.
