SLU, the Swedish University of Agricultural Sciences recently published a cost benefit analysis of the socio-economic effects from implementing household water treatment in rural India. Erik Boije and Gustaf Eskhult (Agricultural program- Economic’s and Management) conducted the study based on the performance of three technologies: Solvatten, Elextrolux Oxy3 and Airwaterwell in the regions Gujarat, Harayana and Uttar Pradesh. The cost efficiency and social impact numbers of Solvatten outperformed the alternatives by far. The social impact factor obtained from the study was 1:36. With a 36 times the investment, it makes a lot of sense for a subsidy to be put in place to help an indian household gain access to the Solvatten solution.
