Water, Sanitation and Hygiene

Water Supply

In the area of water much progress has been made and the world is now on track to meet the MDG water target. However, there are still 884 million people who use unimproved and usually unsafe water sources. All over the developing world, women and girls spend hours every day on the drudgery of hauling water for their families from distant sources. And in urban slums, many poor people are forced to pay exorbitant prices for water from vendors. Water from these sources is often contaminated, and rarely enough to meet the needs of households.. All over the developing world, women and girls spend hours every day on the drudgery of hauling water for their families from distant sources. And in urban slums, many poor people are forced to pay exorbitant prices for water from vendors. Water from these sources is often contaminated, and rarely enough to meet the needs of households.

Poor quality water causes disease and death (see the Water Quality page), but not enough water is even more dangerous. Without a sufficient quantity of water basic hygiene is impossible and the result is a host of hygiene-related diseases, notably diarrhoea and acute respiratory infection (ARI), the two greatest killers of children.

Studies show that when water sources are more than 30 minutes away from their homes, people – and especially children – are highly vulnerable to hygiene-related diseases. But many people live further away from their water. UNICEF surveys from sub-Saharan Africa, for example, show that over 40 percent of households are at least this far from the nearest water source. In some areas the situation is getting worse. Environmental degradation, over-pumping and now global warming is further diminishing already scarce freshwater resources.

Improving access to water – or “household water security” – is a key part of UNICEF efforts in the WASH (water, sanitation and hygiene) sector. UNICEF country offices support a variety of programmes with the goal of permanently improving families’ access to safe and affordable water sources at reasonable distances from the home. Activities include support to well drilling and handpump installation programmes, the development of appropriate alternative technologies such as rainwater harvesting, support to community water management and maintenance systems, and the development of national policies, finance arrangements and other “enabling environments” to facilitate affordable and sustainable water systems for poor people.

Water supply is also a key component of the Guinea Worm Eradication Programme, in which UNICEF works with the Carter Center, WHO and other partners in the African countries where the disease remains endemic. Much progress has been made by the programme, and the hope is that transmission of guinea worm can be halted in 2009.
