In our ever growing knowledge around water and conservation, knowing how much water does a shower use, is one of the things that will allow you to be a better global citizen. On average older style, showerheads can use anywhere between 15-20 litres per minute. So a 15-minute shower will use approximately 300 litres of water or over 100,000 litres of water per year per person.
How much water does a shower use depends on your equipment
It is actually quite amazing when you realise how much water a shower can actually use, but the above figure is based on old inefficient shower heads and all new establishments have minimum efficiency ratings. A three-star showerhead will cut your water usage in half to around 9 litres of water per minute. That in effect would save around 50,000 litres of water per year per person.
The truth of the matter is that bathroom in general is an extremely water intensive room, especially the toilet. When you think about the clean drinking water that we flush down the toilet everyday, it seems kind of crazy. These are the privileges we do have living in such a great nation, but these are also the things we should consider when being good global citizens.
Tips to reduce water use in the shower
- First and foremost update your showerhead, get the best water efficient shower head to save what you can.
- Try taking shorter showers. Invest in a shower timer to help monitor how long you shower for.
- Try collecting water in a bucket while you wait for the shower to heat up.
- For those that shave their legs, try doing so beforehand and not in the shower.
- When upgrading your hot water system next, consider investing in an instant hot water system which will prevent wastage when waiting for the water to heat up.
