The aim of the trials was to help change negative attitudes towards handling urine (and human excreta in general), which can be a major obstacle to the adoption of ecological sanitation (ecosan). Ecosan was deemed the most appropriate form of sustainable sanitation to introduce in Bihar, since it can not only help to reduce the health and environmental impacts of open defecation but can also improve rural livelihoods and nutrition for small-scale farmers through the productive reuse of treated excreta in agriculture.

The pilot project activities attracted a lot of interest among local farmers, leaders and agricultural experts, inspiring the wider adoption of both urine harvesting and other forms of ecosan in surrounding communities.

The urine harvesting and trials were supported under a three-year action-research project carried out collaboratively by SEI and the WASH Institute, India, with funding from the Swedish International Development Cooperation Agency (Sida).
