Untreated sewage is the biggest source of water pollution in India with around 70 percent of the raw sewage generated in urban areas entering lakes, rivers, seas and underground aquifers.

The treatment facilities are simply not able to match the sewage generation capacity of toilets. Lack of water in many places also reduce the use of toilets.
