IISc researchers develop wastewater treatment, recycling system

The Bengaluru based Indian Institute of Science researchers have developed an efficient decentralised wastewater treatment and recycling system for rural areas. A study on decentralised wastewater treatment systems developed by the premier institute was published in the Journal of water Process Engineering. The model is demonstrated in Berambadi Primary school in a remote village in Karnataka.

The Assistant Professor at the Centre for Sustainable Technologies in Indian Institute of Science, Lakshminarayana Rao has informed that the water treatment system demonstrated by them is economical and enables reuse of wastewater, reducing dependence on freshwater resources. He informed that the 667 litres of grey water can be treated daily, thereby saving around 180,000 litres of water annually.

The water that drains out of the wash basin and kitchen is treated and recycled after removing the oil and grease and used again for non potable purposes such as toilet flushing and gardening. Based on the success of this sustainable wastewater management project, several other schools in Karnataka have approached the institute to set up the system in their schools also.
