Residents are invited to a drop-in information session on the latest plan for the St Mary’s Bay and Masefield Beach water quality improvement project. Drop in any time between 4pm and 7pm on Thursday, November 9, upstairs at the NZ Marine Building, 85 Westhaven Drive. The design and project team, including engineers working on the project, will be on hand to answer your questions.
The project is designed to significantly reduce the approx. 100 sewage overflows each year into St Mary’s Bay.
The technical team has decided that the preferred alignment of the new pipeline will be along the southern-most route of the original proposals. It will pass under about 30 private properties between Shelly Beach Rd and New St, generally in rock, 15-20m below ground level.
Auckland Council will contact affected property owners to explain the project in detail.
How it works:
The new infrastructure will collect combined stormwater and wastewater overflow (from London St, Hackett St and Sarsfield St in a new pipeline called a storage tunnel.
This pipeline will be able to collect and return flows to the main sewer at the Pt Erin Park pump station.
When there is no spare sewer capacity, such as during heavy rain, it will discharge flows out into the harbour via a new and extended harbour outfall.
This local project is designed to integrate into widespread long-term sewerage network improvement plans being developed by Watercare and Healthy Waters (a division of Auckland Council).
