4 Tips to Save Water in the Toilet

Updated 1 January 2020 04:52 PM

On average, 40% of the average household’s water consumption is used in the bathroom 


The toilet is a main consumer of this water usage with every individual flushing an estimated 30 times per week.


  1. Check the toilet for leaks. Put a few drops of food coloring in your toilet tank. If the color begins to appear in the bowl without flushing, you know you have a leak that needs to be repaired. 
  2. Never flush cigarette butts or other trash down the toilet. Use the rubbish bin.
  3. Put a plastic bottle filled with sand in your toilet tank to cut down on water used per flush by older model toilets. Place bottles safely away from the operating mechanism and never use bricks, which disintegrate after a while and damage the mechanism.
  4. For the more committed water saver, don't flush after every pee, especially with small children.

Science Notes

Dual flush toilets use around 5 litres of water per flush, single flush toilets on the other hand, use on average 11 litres of water.

If you are building or renovating, check out the fabulous new sustainable toilet designs with attached basins. These toilet suites use fresh water for hand washing before flowing into the cistern to complete the flush.
