Almost 900 million people across the world, or one in eight people, do not have access to safe drinking water. At the same time, global water consumption is growing at twice the rate of population growth. At current estimates, 2025 will see at least 3 billion people finding it difficult, or even impossible to meet their basic daily water needs. With water deficit comes millions of deaths as people turn to contaminated water sources. Diarrhoea, hepatitis, cholera, and typhoid are all preventable diseases, yet run rampant in communities with water issues.
