To produce one cup of coffee we need 140 litres of water. This is a global average. (www.waterfootprint.org)

Thousands of people are writing about water, and millions are reading this. Today I join in this effort by sharing an idea.

So why are we still flushing our toilets with clean drinking water?

I find this absolutely ridiculous. During an average day I use the toilet about 5 times, the shower once, the tap about 10 times and I do the dishes. And it is raining outside.

And of course we can build all kinds of advanced rainwater or grey water systems in new homes, but what about the millions of toilets and wash rooms that are already out there?

Isn’t it really easy to re-direct some pipes, do some plumbing, put a bucket somewhere in your house and done?

And is there a company that does that?

Some of what I have found so far:

• WaterSaver Technologies Aqus Uses Sink Greywater for Toilet
  
  
• Collect rainwater for toilet water
