It’s the little things, done by many, that can make a difference on a global scale. Water is becoming something we never expected it to be, even here in the West – a commodity in limited supply, something that needs to be used sparingly. One use of water that could be cut back a great deal is the flushing of toilets, and a new design of the classic piece of bathroom furniture could help us all do our bit, if you’ll excuse the phrase. The Propelair WC employs air pressure for increased performance, and hence uses a mere 1.5 litres per flush, as opposed to the 9 litres of the average UK toilet.
