Water is the source of all life. Contaminated drinking water can lead to diseases such as typhoid and cholera, causing illnesses and deaths.
Safe water is vital for drinking, food preparation, personal hygiene and domestic use.
Poor access to safely-managed drinking water means that people use drinking-water sources that are contaminated with human waste, which spreads bacteria, viruses, parasites and worms. These transmit diseases such as diarrhoea, cholera, dysentery, typhoid and polio. (WHO)
Each year, there are about 502,000 diarrhoeal deaths related to contaminated drinking water.
Diarrhoeal disease is the secondcause of death in children under five, killing an estimated 340,000 children each year. 50% of child malnutrition is associated with unsafe drinking-water and inadequate sanitation and hygiene (WHO, 2008). These are preventable with safe water and improved sanitation and hygiene.
Water sources are often far from homes in developing countries. Women and girls often spend much of their time and energy fetching water. People are forced to rely on surface water, unprotected and possibly contaminated wells or vendors selling water of unverifiable provenance and quality.
Universal access to safe drinking water and adequate sanitation and hygiene would reduce the global disease burden by 10%.
For every $1 invested in water and sanitation, an average of at least $4 is returned in increased productivity. (Sanitation returns $5.50 from $1 and water returns $2 from $1). (WHO, 2012)
