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.

Featherston Wastewater Treatment Plant

At the Featherston Wastewater Treatment plant, sewage flows through a facultative pond, a maturation pond, and ultraviolet treatment. Discharge of the treated effluent is managed to Donald’s Creek depending on the conditions of the Resource Consents.

The plant was granted new consents on 25 August 2009 with a variation granted on 12 November 2010. These consents expired on 25 August 2012. The plant is currently operating under this expired consent. An application for new consents is on-going.

In general, the consent allows SWDC:

  • to discharge treated wastewater to Donald’s creek at up to 9,000 cubic meters per day in dry weather and up to 12,000 cubic meters per day in wet weather.
  • to discharge odours and other contaminants from the treatment process within the boundary.
