How Much Water? – Useful Facts

How Much Water Use

How Much Water Do Things Use?

As you might expect, we deal with all types of unique and varied 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. On the topic of calculators, the numbers from this report are used in our Water Usage Calculator

So let’s start with that example of a bath, one of many things that can leak water….

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.
