Tauranga city’s water use
Tauranga’s 7-day average water use sits around 43.7 million litres of water per day and in previous summers has climbed to 58 million litres per day. However, after three dry summers in a row, the streams that supply the city with water are at the lowest levels seen going into summer, which means anything higher than 50 million litres per day is unsustainable this summer.
Water use in this graph is reflected as a ‘rolling’ measure. This means daily numbers are expressed as a rolling average over 7 days – smoothing incidental peaks and highlighting trends instead of isolated extremes. This graph is updated weekly on a Tuesday.
Additional note to explain water use:
- Water use in the graph is measured in m3 (cubic metres)
- 1 cubic metre equals 1000 litres
- 50,000 cubic metres equals 50 million litres.
How can I save water at home?
- Fix any leaking taps, pipes or cisterns. A leaky tap could drop up to 3 litres of water per day.
- Put a jug of water in your fridge for instant cold water.
- Make sure the dishwasher is full before you use it.
- Scrape dirty dishes rather than rinsing. Modern dishwashers can take it!
- Put the plug into the sink to wash dishes or scrub vegetables. Don’t leave the water running; taps use up to 6 litres of water per minute. You could save around 20 litres of water.
- Turn off the tap while shaving or brushing your teeth. You could save up to 5 litres of water!
- Take shorter showers. A shower uses 10-12 litres of water per minute so cutting your shower by just one minute saves more than you expect.
- Collect water from your shower for watering your garden – this could be around 20 litres for your garden.
- Use the short toilet flush when you can, that uses about half the water of a full flush. The average flush uses between 6 and 32 litres of water, so using a half flush can help a lot.
- Install covers on pools and spas to reduce water evaporation.
- Use a bucket to wash your car rather than a hose – you could save up to 100 litres of water!
- Wash your car on the grass.
- Use a broom, not a hose, to clean paths.
