Rainwater Harvesting: 170 sq.m. of roof area collets up to 272 m3 per year of rainwater and stores in an underground tank with a capacity of 10,000 liters. Excess water is diverted unto a dug-well for ground water recharge.
ECOSAN: An ECOSAN toilet diverts faeces into a 50 litre bucket and urine to a 200 litre PVC tank. Collected urine and faeces is used as organic fertilizer.
Wastewater Treatment: About 1000 litres of waste water per day generated by 40 staff members and a research laboratory is treated in a vertical flow sub-surface constructed wetland with an area of 18 m2 filled with gravel and coarse sand layers, and planted with Phragmites karka(Narkat). The treated wastewater is used for toilet flushing, vehicle washing and gardening.
Drinking Water Treatment: A Bio-sand filter is used for removing turbidity and other pollutants from drinking water. Treated water from the filter is disinfected by using PIYUSH and SODIS technology.
