Water

The Facts about Water at Global Level

 

  • An estimated 663 million people worldwide do not have access to an improved drinking-water source (UNICEF/WHO, 2015), and an estimated 1.9 billion people rely on drinking-water that is faecally contaminated (Bain et al., 2014). Improved water sources that are not operated or maintained properly may deliver water that is microbiologically contaminated (WHO/UNICEF, 2011). In addition, microbial recontamination often occurs during collection of water at the source, transport and storage within the home (Wright, Gundry & Conroy, 2004).
  • In 2015, 91% of the world’s population had access to an improved drinking-water source, compared with 76% in 1990.
  • 2.6 billion people have gained access to an improved drinking-water source since 1990.
  • 4.2 billion people now get water through a piped connection; 2.4 billion access water through other improved sources including public taps, protected wells and boreholes.
  • 663 million people rely on unimproved sources, including 159 million dependent on surface water.
  • Globally, at least 1.8 billion people use a drinking-water source contaminated with faeces.
  • Contaminated water can transmit diseases such diarrhoea, cholera, dysentery, typhoid and polio. Contaminated drinking-water is estimated to cause 502 000 diarrhoeal deaths each year.
  • By 2025, half of the world’s population will be living in water-stressed areas.
  • In low- and middle-income countries, 38% of health care facilities lack any water source, 19% do not have improved sanitation and 35% lack water and soap for handwashing.
