The current water supply situation

Auckland’s water supply is currently stable. Stage one outdoor restrictions end on Saturday 23 October 2021.

Recent rainfall events have had a positive impact on Auckland’s water storage, with dam levels rising past 90% for the first time since 4 February 2019. As a result, we reviewed our position on water restrictions and on Thursday 21 October Auckland Council’s governing body unanimously agreed to lift the region’s remaining outdoor water restrictions.

Over the 17 months that restrictions were in place we:

  • Completed the Pukekohe East reservoir, a key project enabling our Waikato Water Treatment Plant to treat up to 175 million litres a day (MLD)
  • Completed the Waikato 50 plant in record time, taking our peak production from the Waikato River to 225 million litres a day
  • Built a new Pukekohe Water Treatment Plant, which treats up to 5MLD
  • Built the first stage of our Papakura Water Treatment Plant, which treats up to 6MLD
  • Upgraded our Onehunga Water Treatment Plant, boosting treatment capacity by 4MLD
  • Carried out acoustic leak detection on more than 5,500 kilometres of our water network to find and fix invisible leaks. This has saved an estimated 9MLD.
At the same time, Aucklanders saved 20 billion litres of water. Ka pai!

Our current water sources

At the moment, we are optimising abstraction from our dams to allow them to fill up as much as possible when it rains.

We’re also continuing to utilise our Waikato Water Treatment Plant to further enhance the recharge of our dams.

We’re fortunate to have a diverse range of water sources – dams, rivers and aquifers. This means we can balance production rates at our treatment plants to ensure we’re making the best use of the water we have available.

For example, if our small dams in the Waitākere Ranges are full and close to spilling, we maximise production at our Huia and Waitākere water treatment plants that treat water from these dams.
