BENGALURU: It has been demonstrated by researchers from the Indian Institute of Science, that a decentralised grey water treatment system can be installed and easily operated in a rural Indian setting, and help reuse waste water. In an attempt to provide a feasible water treatment option to prevent groundwater contamination in rural areas of developing countries, they installed a decentralised greywater treatment system at Berambadi Primary School in Chamarajnagar district, a year ago.
This process effectively saved up to 1,80,000 litres of water annually, which was stored in an overhead tank for non-potable uses in the school. The system comprises slow sand biofilters, anaerobic sludge bioreactors, aerators and ozonation system. In collaboration with researchers from the UK, the IISc team studied the system’s performance over 12 months.
