Water is one of the most valuable resources on Earth. It covers over two thirds of the planet’s surface, makes up around 70% of the human body and is essential for life. For many people a consistent supply of clean, safe water is on tap. But for many others life is not so easy.

According to a United Nations report, African and Asian females walk on average 6km each day carrying up to 20kgs. An estimated 125 million physically demanding hours are spent each day collecting water, which could be otherwise spent in work or education.

The amount of water being used

In developing countries, 20 litres of water is enough to meet basic drinking, cooking and hand washing needs, a report authored by the World Health Organization says.

The same volume of water, 20 litres, is the minimum amount used during a one minute shower under a conventional shower head. Put another way, the average person uses more water during a 1 minute shower than most sub-Saharan Africans use in a day.

Consumption patterns are […]
