Saving water at home

Bathroom

We use more water in our bathrooms than in any other (internal) part of the house. It’s a great place to start looking for ways to save water.

Toilet

Up to 16% of household water is flushed down the toilet. The following tips can reduce the amount of water used and in turn help reduce your water bills.

  • Don’t flush needlessly. Use the half-flush option on dual flush systems and never flush items other than toilet paper down the toilet.
  • Replace your older-style toilet suite with a 4-star WELS Scheme dual-flush system. This can save up to 8 litres of water with every flush.
  • Use tank water to flush. Talk to your plumber about having your rainwater tank internally plumbed to your toilet.

A leaking toilet can waste more than 60,000 litres of water a year. Check for leaks by putting a little food colouring in the cistern. If the colouring begins to appear in the bowl without flushing, have the cistern rubber repaired immediately. Flush as soon as the test has been completed.

Showers

A standard shower can use 20 litres of water per minute, and accounts for up to 24% of household water use.

  • Install a water-efficient shower head. A WELS Scheme 3-star rated shower head will use no more than 9 litres of water per minute.
  • Take a shorter shower. Shorter showers not only save water but help reduce the amount of energy associated with heating the water.
  • Insulate your hot water pipes. This means you won’t need to wait as long for the hot water to flow through—saving you both water and energy.
  • Make sure your hot water system thermostat is not set too high.
  • Use a bucket to catch water while the shower warms up. You can then reuse this water on your garden.

Bath and basins

You can reduce water use in baths and basins.

  • Insert a plug when washing your hands in a basin.
  • Turn off the tap while cleaning your teeth or shaving.
  • Use as little water as possible in the bath by placing the plug in before you turn on the tap and fill the bath to less than a third full.
  • You may also like to bath small children together.
  • Have a licensed plumber install flow restrictors and aerators to taps around the house.
  • Replace your older-style tapware with high star rated WELS Scheme products.
