Overview This zero discharge toilets are developed by Department of Civil Engineering, IIT Kanpur. In these toilets, the solid and liquid parts are separated, collected and reused. A specialised structure ‘separator' diverges the liquid (urine and flushed water) in the outward direction and is collected in a tank while the solid part in the form of slurry is dropped into another chamber called retention tank. The fecal slurry is collected and converted into manure through composting. The liquid is further treated and reused for flushing the toilets. Salient feature
