This technology can transform the way arsenic is removed from groundwater in Ganges, Brahmaputra and Mekong delta where the arsenic is of arsenopyrite origin, saving millions of lives. This includes affected areas of India, Bangladesh, Cambodia, Nepal, Vietnam and Thailand. The technology is scalable from a production capacity of 10,000 litres/day (USD 4,000) to 1,00,000 litres/day (USD 20,000) for each plant, catering to the drinking water needs of 2000 to 20000 people, depending on the soil & water conditions.
Scope of Replication in Ganga-Brahmaputra Delta Region, India
There is good scope for application of the project on a larger scale for the benefit of a good section of the population in arsenic affected areas. The main strength of the project team is the various centers of RKVM where the Mission has earned reputation and good will among the people because of their long term social services. There is an established connectivity with the rural sector and resource persons are available in these centers that can be of immense help to the project team.
Huge areas of West Bengal (8 districts & corporation/ municipal areas) are affected with arsenic contamination from arseno-pyrite origin. If each village is provided with one water treatment plant, then over 3000 plants are necessary in West Bengal only. The potential is therefore infinite. Moreover the country of Bangladesh which is adjacent to West Bengal is suffering from similar situations. The application of low cost eco-friendly safe water supply technology is essential for both drinking & irrigation purposes.
Scope of Replication in North America
