The quality of the water supply in Nepal is always the matter of questioning due to lack of proper treatment system, no use of disinfection and no proper maintenance. The conditions in the hilly and mountainous regions are even worse compared to the plain areas of Nepal with limited sources of water. Even though the source is found, it remains hard to make the pipeline distribution system. Hence the people have to collect water from the far sources and spend hours for the daily need of water. The tragedy behind water use in Nepal is that, the water collected from this much of hardship is also not safe for drinking purpose due to the pollution in the source or due to bad storage vessels. The fact sheet released by Water Partners International depicts that 88% of the whole diseases are the waterborne diseases. 4,900 children are dying every day due to water borne dieseases. According to Asian Development Bank (ADB) report sanitation-related diseases account for 72 per cent of total ailments and diarrhea continues to be one of the leading causes of childhood deaths in Nepal.

Therefore an instant action for the safe drinking water supply is the must in the present context of Nepal. Among various techniques developed for water disinfection, Chlorine solution (sodium hypochlorite) - a chemical compound that destroys and inactivates micro-organisms and pathogens in water - is a powerful disinfectant widely used.


The general objective of this campaign is to provide the schools and communities with safe drinking water and improved sanitation of the surrounding.

Key intervention

In addition to other water disinfection technolgoies, ECCA is focussing on the use of chlorine solution – which is locally produced from concentrated common salt solution, through an electrolysis process, by using the Swiss Technology "WATA device". It is simple to use, robust and sustainable technology. The device requires only DC source or solar panel, a clean plastic container (not metallic), common salt and clear water. The necessary quantity of active chlorine concentrate (sodium hypochlorite) for water treatment depends on the initial water quality. For an average water quality, 1 litre of concentrated salt solution can treat about 52,000 litres of water. Once treated water is used, health condition will improve; thereby enhancing the livelihood of the general populace.
