Water like you oughta

This summer, we're asking you to think carefully about how and when you use water, particularly outside. This is so our water supply doesn't come under too much pressure. Check out our tips below.


Get the family together!

Talk with your family about ways to save water or challenge each other around what they did today to reduce their waste.

Check for leaky taps.

Check all taps on your property for leaks. Even one drip a second can waste over 5,000 litres per year.

Ensure your garden retains the water it needs.

Water before 6am or after 9pm, and only when it's not windy, otherwise water can evaporate before being used by plants.

Target water to plants that really need it.

Use a trigger gun nozzle on a hand-held hose or watering can.

A rainwater tank is a great investment.

A tank ensures you have fresh water available, and can be a key water source for your family in a natural disaster.

Gardens don't need water every day.

Try watering on alternate days: even street numbers on even days, odd street numbers on odd days. A deep soak is better than frequent light watering.

Keep your shower under 5 minutes.

Install a shower timer (or water-efficient shower head) and save up to 3700 litres of water per month!

Make water conservation a fun game for your family.

Set a challenge for everyone to turn off the tap while brushing their teeth.

Use your dishwasher wisely.

Ensure that your dishwasher is full before running a load.

There are alternatives to using running tap water.

Wash fruit and vegetables in a bowl of water, then pour the water onto pot plants.

Washing machines account for up to 20% of water used in most homes.

Use a more water-efficient front loader and ensure you always have a full load.

Every action to conserve water helps.

Reducing laundry by one load can save up to 50 litres of water per week!


Level 4 water restrictions (no outdoor water use) are currently in place for Akaroa, Duvauchelle and Takamatua. For updates, check our water restrictions page or call 0800 800 169.

Saving water during summer is important

Most summers, the demand for water in Christchurch doubles.  When this happens, we need to draw water from all of our wells to cope with demand.

Sometimes, we may even use water faster than we can pump it and fill our reservoirs, leading to supply issues and reduced pressure.  This can impact activities like firefighting.

A key way you can conserve water is to check all taps on your property for leaks. Even one drip a second can waste over 5,000 litres per year.
