New wastewater tunnel reaches into Whau

New link sewer line from May Rd to Miranda Reserve and access points

Recent Meet the Contractor events were held for local residents at Dundale Ave, Glenavon and Haycock Ave, Mt Roskill, near two of the worksites for the project.

Watercare is building a branch line called the Central Interceptor link sewer which will be 2.5m diameter. It will run from the 4.5m diameter Central Interceptor in May Road to terminate at Mirada Reserve near Wolverton St. The pipeline will be about 20 – 30 metres underground, so there will be five access shafts used during construction.

Work has already started at Haycock Ave with the demolition of two houses. The site is now being prepared for work to start on the shaft. Once commissioned in 2023, the existing Western Interceptor network will connect to the new link sewer.

The Haycock and Dundale sites will have minimal impact on traffic during the year and a half construction period. A smaller shaft at Whitney St will be a little more difficult as it is on the roadside.
