Traditional method of removing odour is flushing of Urinal Pan with water, which dilutes & transport the urine into main line from drainpipe. However, it requires a huge amount of water.  Since urine is mostly water, it does not require any extra water for its regular smooth flow into the main sewer line, when urine mixes with water it produces Ammonia which is responsible for the smell. 

Based on this concept, KOSHISH developed a mechanical means to reduce the odour and to conserve water – The OlerTrap – Flush Free and Odour Free Urinal Kit.
