Giving 350,000 swimmers the best of Auckland’s beaches

In 2017, Auckland was ranked third in the international Mercer Quality of Living index. What will it take for Auckland to take the number one spot? Well, one challenge the city faces is the unpredictable wastewater pollution of its popular beaches. We used the power of real-time data to make a change.

Act with conviction

Impact progress

After heavy rain in Auckland, sewage networks can overflow and pollute the city’s harbours. Swimmers don’t know where it’s clean and safe to go into the sea. What if we could make sure they always knew the best place to go for a swim?

We pinpointed 10 invaluable data streams, including final effluent quality, network hydraulics, weather data and tidal movements. These gave us 1bn data points which are brought together through Moata, our smart infrastructure platform, where they are analysed every single day to show us the water quality across 84 different beaches. We are sharing this information with the public in real-time.

The end result is a platform called Safeswim that helps 350,000 people enjoy Auckland’s waters all year round. Armed with vital real-time data on its wastewater infrastructure, Auckland Council is investing public funding at relevant pressure points to build a better network for the future. From insight to impact, we have taken Auckland a step closer to its vision – to be the world’s most liveable city.
