Water restrictions
Did you know that Wellington’s daily water supply is finite?
In winter, when there's plenty of rain and the river levels are healthy, we can supply up to about 220 million litres of water per day.
In summer, when it’s hot and dry and river levels drop, this can go down to 170 million litres of water per day.
That might sound like a lot, but due to leaks in our aging network (which we're working hard on finding and fixing), population growth and the fact that Wellingtonians use on average more water than any other metropolitan region in Aotearoa, our water use adds up fast – getting up to 205 million litres per day in summer and dipping into our stored water!
But this stored water is precious and is critical for getting through a long dry period, and in summer it’s harder to refill the lakes. So over time, they get lower and lower, leaving Wellington with less and less water stored and available until next winter.
This means we have to be careful to manage our daily water supply and demand, and don’t use too much.
That’s where water restrictions come in. They help everyone understand how they can best manage their personal water use, so there’s enough to go round for the necessities.

Water Restriction Level 1
Use sprinklers every second day
If you live in an even numbered house, you can use sprinklers or irrigation systems on even numbered days between 6-8am and 7-9pm. If you live in an odd numbered house, the same rules apply for odd numbered days.
This helps limit water evaporating in the heat of the day, spreads the load of daily water demand, and helps manage daily supply levels.
You can use handheld watering devices any time, on any day, so long as you don’t leave them unattended.
Water restriction Level 1 applies all year round for Upper Hutt and South Wairarapa. Level 1 automatically comes into effect with Daylight Savings in September for Lower Hutt, Wellington City and Porirua.
Water Restriction Level 2
No sprinklers or irrigation. Only water your garden by hand.
All unattended watering systems are banned – ie. sprinklers and irrigation systems.
You can water your garden by hand anytime, on any day, so long as you don’t leave your garden hose or watering device unattended.
Watering your garden by hand helps reduce water waste.

Stop residential outdoor water use.
There is a ban on residential outdoor water use. You can continue to water your vegetable garden using a watering can or bucket.
Businesses can continue to operate as normal, but please be pragmatic and responsible when watering.
Following Level 3 restrictions can reduce the risk of moving to Level 4.
Water Restriction Level 4
Stop residential outdoor water use, reduce indoor water use.
Water Restriction Level 4 means there is a significant water shortage.
At level 4 there is a ban on outdoor water use, and we need to reduce indoor water use to ensure there is enough water for everyone.
To help save water, people should stop all outdoor water use, take 2 minute showers and limit their laundry use to 1 load per person per week.
