Over the next six years Watercare are building the Central Interceptor tunnel to help make Auckland's waterways cleaner. The Central Interceptor will run underground from Grey Lynn to the Māngere Wastewater Treatment Plant. It will have several link sewers and shafts along the route for collecting and transferring wastewater into the tunnel.

Once completed, the tunnel will be 14.7 kilometres in length, the longest in New Zealand. At 4.5 metres in diameter, it will be high enough to fit a giraffe and wide enough to fit four rhinos side by side.

Buildmedia created an interactive presentation that showcased the scope of the project in an easy to understand format. Each site was modelled in great detail and is fully interactive allowing the user to move around the site and focus on different details of the project. Watercare now have the ability to take this presentation out to community stakeholders and keep everyone informed.
