Translating the Human Rights criteria into action is a challenge for water and sanitation professionals, particularly for regulators. Mohamed Tawfik and the IWA Communications department for Water Policy and Regulation have procvided a helpful outline and infographics to illustrate some of the key criteria & principles in relation to drinking water supply and sanitation services.

Journal author Dr Ephias M. Makaudze outlines the significance of his studies into the importance of clean water and safe sanitation to people living with HIV and AIDs in South Africa, where rising urban slum population increasingly strains the resources of local municipalities.

Water is life – and life on earth is linked to water. Our existence is dependent on water, or the lack of it, in many ways, and one could say that our whole civilization is built on the use of water. This article examines the influence of water on public health throughout history. Farming and the development of settlements lead to the beginning of the problem that faces mankind  today – how to get drinkable water for humans and cattle and how to manage the waste we produce. The availability of water in large quantities has been considered an essential part of civilization throughout the different periods: Roman baths needed a lot of water, as do the water closets and showers used in current Western civilization. The importance of good quality drinking water has been established for years. However, the importance of proper sanitation was not understood until the 19th century.

The health consequences of inadequate water and sanitation services include an estimated 4 billion cases of diarrhea and 1.9 million deaths each year, mostly among young children in developing countries.  Diarrheal diseases lead to decreased food intake and nutrient absorption, malnutrition, reduced resistance to infection, and impaired physical growth and cognitive development.  Since 1996, a large body of published work has proven the effectiveness of interventions to improve water quality through household water treatment and safe storage (HWTS) at reducing diarrheal disease.  However, not all of these interventions remove the turbidity that causes water to look dirty.  Although the following options are not proven to reduce diarrheal disease incidence on their own, they can be used to pre-treat water to reduce turbidity before the use of household water treatment products.  These options mechanically (through filtration) or chemically (through flocculation and settling of suspended material) remove particles and reduce turbidity.  These pre-treatment methods may also increase the efficacy of household water treatment products by removing contaminants that interfere with disinfection and physical filtration processes.
