The National Environmental Engineering Research Institute (NEERI) Nagpur and UNICEF Bhopal, Madhya Pradesh have developed, implemented and evaluated greywater reuse systems for small buildings (schools) in rural areas. During 2005 and 2006, NEERI and UNICEF collaborated to investigate the possibility of recycling greywater(bathroom water) in residential tribal schools in rural Western Madhya Pradesh. The water reuse or recycling systems collected, treated and reused bathroom water (shower non toilet/black water) for recycling and flushing of toilets. The drive for this technology was a result of decreasing availability of water, lowering of groundwater table and increase in fluoride concentration in groundwater. Additionally, with the increase in demand for water due to increased coverage of rural areas with toilets under the Total Sanitation Campaign (TSC), there was a need for augmentation through appropriate technologies, to provide water for sanitation.
