Auckland has taken a huge step forward in its mission for cleaner waterways and beaches with the official activation of the southern section of Watercare’s Central Interceptor project. The milestone marks a crucial moment in the city’s largest wastewater infrastructure project to date.

The southern half of the 16.2-kilometre tunnel, spanning from May Road in Mount Roskill to the Māngere Wastewater Treatment Plant, is now live. This advancement enhances Auckland’s wastewater network, helping to reduce overflows into the environment and improving the quality of local waterways for future generations.

A formal event was held at the new pump station in Māngere to commemorate this achievement. Auckland Mayor Wayne Brown officiated the proceedings, issuing the start-up order before participating in a symbolic first flush.

The event also served as an opportunity to recognise the dedication and hard work of the 600-strong Watercare and Ghella Abergeldie Joint Venture Central Interceptor project team. Since the project’s commencement in 2019, these professionals have been working tirelessly to construct this vital infrastructure, which will play a key role in safeguarding Auckland’s environment and public health.

This massive infrastructure upgrade will play a key role in safeguarding Auckland’s environment and public health, ensuring a cleaner and healthier city for generations to come.

With each phase of construction bringing the project closer to completion, the Central Interceptor stands as a testament to our commitment to sustainable development and environmental protection.
