Drought response

Stage one water restrictions are now in place

Residential water users cannot:

  • Use an outdoor hose or water blasting device when connected to the metropolitan supply network.
Commercial and other non-domestic water users cannot:
  • Use an outdoor hose or water blasting device when connected to the metropolitan supply network unless it is for health, safety, emergency or biosecurity reasons.
  • Operate a car wash unless it uses recycled water.
  • Water sports fields, plants or paddocks unless they have an irrigation system that is fitted with soil moisture or rain sensors.
Important:
  • The restrictions only apply when connected to the metropolitan water supply network.
  • There are a number of outdoor cleaning, car cleaning and construction companies offering services using non-potable (untreated) water. See the list here.
  • If you have a rain water or grey water tank you can use that water as you wish ie: you can connect a hose to those tanks and wash your car/vehicle, boat etc.

About the drought

Since the start of the year, the region has received significantly less rainfall than normal. This is having a big impact on our water supply. On 15th April, the total volume of water stored in our dams dropped below 50 per cent for the first time in more than 25 years. We desperately need to preserve what’s left. Please use water wisely and reduce wastage of this precious resource by:

  • Keeping your showers short (four minutes or less)
  • Run your washing machine and dishwasher only when they’re full
  • Don’t wash your car
  • Don’t water blast your house
  • Don’t hose your lawn

Hunua rainfall to 10 August 2020

Current rainfall and the forecast

Click to enlarge the Hūnua rainfall graph to see this year's rainfall to date compared to normal rainfall for this time of year. The Hūnua Ranges is our biggest catchment area with dams covering 534 hectares.

The table below shows the likelihood of rain in the coming weeks. A negative figure (-) indicates a less than normal chance of rain, whereas a positive figure indicates a higher than normal chance of rain.
 
Ranges 10-16 August 17-23 August 24-30 August 31 August - 6 September
Hūnuas 15% 101% -7% -8
Waitakere rainfall Nov 2019 - 10 August 2020

Actual rainfall versus normal Nov 2019 to 3 August 2020

Our cup needs topping up

From November 2019 to 10 August 2020, the average rainfall across all our rain gauges has been 977mm. In comparison, the normal rainfall we'd expect over that period is 1302.5mm. The deficit of 325.5mm has had quite an impact on our water storage.

Fun facts about our dams

  • Our dams in the Hūnua Ranges are by far the biggest - combined they cover 534 hectares. Our Hunua dams make up 60 per cent of Auckland’s water.
  • Our dams in the Waitākere Ranges cover 162 hectares and make up 20 per cent of Auckand's water.

As dam levels continue to ebb and flow, we're maximising production elsewhere

  • To reduce the demand on our water storage dams, we are maximising production at our Waikato and Onehunga treatment plants.
  • We're working to return two former water sources – Hayes Creek Dam in Papakura and a bore in Pukekohe – to supply.

Total water storage

Tuesday 11 August 2020
Total water storage = 60.05%


Our total water storage is the combined volume of water currently available across our dams. The water storage graph shows how our current storage is tracking against the historical average.

The table below shows our total water storage on each respective Monday (eg: 27 July). It also shows the 24hr rainfall (to midnight on the respective Sunday) across our two main catchments.
 
Date Total water storage (%) 24 hr rainfall in Lower Huia catchment (Waitakeres) 24hr rainfall in Mangatangi catchment (Hūnuas)
Mon 20 July 58.26% 0mm 0.5mm
Mon 27 July 59.69% 0.5mm 1mm
Mon 3 Aug 59.48% 0mm 0mm
Mon 10 Aug 60.04% 2mm 1.5mm
