Work is now underway on a 14.7km tunnel in Auckland as part of Watercare’s $1.2b Central Interceptor project, Stuff reports. The project was started in 2019 and is expected to be completed in 2025. It is expected to reduce sewage overflows into the Waitematā Harbour and help clean up local waterways. The project is the biggest wastewater scheme in New Zealand’s history, and Mayor Phil Goff was at ground zero in Māngere on Friday for the start of the work by the tunnel boring machine, Hiwa-i-te-Rangi.
