How Much Water? – Useful Facts

How Much Water

How Much Water Do Things Use?

As you might expect, we deal with all types of water leaks in properties, and we sometimes get asked questions about how much water is used by everyday household items around the home. Why do we think that is? Well because if we are dealing with something like a Bathroom Leak, say from a bath water leak, then people wonder how much water is potentially leaking into their home from that leak!

We say potentially because, unless it is a catastrophic leak in a property, it would be unlikely to be all of the water leaking. For example, a waste pipe leak from a bath might have a crack in it which will leak a proportion of the water when we pull the plug out. Clearly, what that percentage is will depend on the scale of the crack or break. If the pipe is sheared off, it could be 100% in theory but, on most occasions it will be a small percentage of that, maybe single figures of percent.

That said, if you are losing 5% of your water from a leak then that can add up if it is happening ever day when you have a bath! A bit like you can see on our water leak calculator.

So let’s start with that example of a bath….

People use about 50 to 60 litres of water to have a shower

On the subject of baths and showers, we have some other reports that you might find interesting. This includes an article on shower leaks and another on comparing condensation from baths and showers. Finally, we have a really fascinating article on the most common bathroom leaks.

A kitchen sink holds about 15 – 20 litres of water in them.

Clearly that might be different if you use a plastic bowl in the sink too!

On the subject of kitchens, we have a really useful guide to how useful kitchen extractor fans can be in your home or business. Also, kitchens (including some of the things above) feature in our collection of Slow Motion Water videos which are fascinating for sure.

So hopefully that fun guide was interesting to compare how much water different things in your home hold or use. As we said, that can in turn give an indication of which items might cause how much damage when coupled with the scale of the thing that is causing the water leak.

How much water is on earth?

Cropped Logo

Over 70 percent of the earth surface is water, most of it salt water in the seas (over 95%) and there are around 1.3 billion cubic kilometres in total. A cubic kilometre is 1000m long x 1000m wide x 1000m high which, on its own is one billion cubic meters – so, because each cubic meter is 1000 litres, that is 1 trillion litres per cubic kilometre. So that means there are 1.3 billion trillion litres of water on earth. That is 1,300,000,000,000,000,000,000 litres which is amazing. That is 1,300 quintillion litres or 1.3 sextillion litres.

How much water on earth is fresh water?

Of all the water on earth around 97% is salt water in the oceans and seas. Around 2% is ice and ice caps and glaciers. Just under 0.5% is ground water. With the remaining (under 0.5%) being inland seas, lakes and water in the atmosphere. River water is around 0.0001-0.0002 percent of the total which is surprising to many.
