Miracle of Calcutta

This documentary shows how the ingenuity of local fishermen of Kolkata has helped treat dirty sewage water.

Like in all developing countries, Indian cities can't afford sophisticated state-of-the-art water treatment facilities. And water pollution is very much a reality in this city of two million. This documentary shows how the initiative and ingenuity of local fishermen of Kolkata has become a success story. A simple filtration process makes the dirty sewage water flow through a series of man-made ponds and canals which are full of naturally occurring algae and hyacinths that cleanse the waste water.
