Dear Western Isthmus CLG members,
Watercare would like to let you know about an important project to build a new wastewater tunnel in Grey Lynn. The project is needed as the current combined pipelines in the Grey Lynn area overflow into Cox’s Creek when it rains.
The tunnel will be constructed by a tunnelling machine, between 15-60m deep underground, reducing impact on communities along the project route. The project will start at the Western Springs shaft already required for the Central Interceptor project and tunnelling will continue through to a new shaft site, required at the eastern end of Tawariki Street.
When complete it will have further benefits in the Western Isthmus than the current Central Interceptor proposal, enabling future connections in the area as the population continues to grow.
While tunnelling is not expected to begin until 2022 and work on the Tawariki site in 2023, Watercare will soon lodge the necessary consents for the works.
More information about the project is in the attached flyer. Please let me know if require any more information, as Watercare is happy to talk to you further either in person or at the next meeting. The group will be kept in touch with updates as the project progresses.
