Title
WHO - Managing Water in the Home: Accelerated Health
Gains from Improved Water Supply
Abstract
Around 2.2 million die of basic hygiene related diseases, like diarrhoea, every year. The great
majority are children in developing countries. Interventions in hygiene, sanitation and water supply
make proven contributors to controlling this disease burden. For decades, universal access to safe
water and sanitation has been promoted as an essential step in reducing this preventable disease
burden.
Many different water collection and storage systems and strategies have been developed, described
and evaluated on the basis of various criteria for household and community use in developed and
developing countries. A variety of physical and chemical treatment methods to improve the
microbial quality of water are available and many have been tested and implemented to varying
extents in developed and developing countries. Some of these water treatment and storage systems
have been tested under controlled conditions in the laboratory and implemented in field to evaluate
their ability to produce drinking water of acceptable microbiological quality and to maintain this
quality during storage and use. Some of them also have been evaluated in the field for their ability
to reduce diarrheal and other waterborne diseases among users.
