Water supply situation

Auckland, you are currently in stage 1 restrictions

stage4drop stage3drop stage2drop stage1drop OKdrop
Stage 1 water restrictions mean you must use a trigger nozzle on your hose

At home

What this means for residents on the metropolitan network

  • You can use a hose as long as it is fitted with a trigger nozzle and is attended. This includes water blasting devices
  • Sprinklers and home irrigation systems are not allowed.
Stage 1 commercial water restrictions mean you can use a hose fitted with a trigger nozzle and water sports fields using an irrigation system fitted with soil moisture and rain sensors

At work

What this means for commercial water users on the metropolitan network

  • You can use a hand-held hose as long as it’s fitted with a trigger nozzle
  • You can use a regular hose for health, safety and biosecurity reasons
  • You can operate a car wash
  • You can water fields, plants and paddocks using irrigation systems as long as they are fitted with soil moisture or rain sensors.

Auckland's water supply

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.

Our current water sources

At the moment, with Auckland still recovering from 2020's severe drought, we are minimising production at our Ardmore Water Treatment Plant, which treats water from our four Hūnua dams, and maximising production at our Waikato water treatment plants, where we treat water from the Waikato River. This eases the pressure on our Hūnua dams, allowing them to fill up as much as possible when it rains.

The current water supply situation

Auckland’s water supply is currently stable. Stage one outdoor restrictions remain in place and will likely stay in place over summer. While our dam levels have not yet recovered from 2020's drought, we are in a better position this year thanks to the continued efforts of our customers to save water, and our work to bring online new water sources.

Since restrictions were put in place in May 2020 we have:

  • 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 have saved billions of litres of water. Ka pai!
