Processing Sewage Water With Soil Alone to Cultivate Vegetables in Mumbai

My friends who know me are aware that I am obsessed with sewage treatment as this is a major issue in India. The city that was my home for more than three decades, Chennai, has turned two lovely water outlets to the sea into stinking sewage-bearing canals. And what could be a very valuable industrial resource, is now being entirely wasted. Poor countries like India lack the resources to process waste and reuse it - enter Mr Keshav Tavre, recognized for his efforts by the Smart Planet blog. MIT has taken note of Mr Tavre's work and has mentioned it on their radio station. Perhaps, it is time for more people in India to look at Mr Tavre's efforts now that the USA most recognizable university has endorsed it?
