The next couple of days, I watched Partapji spend time tending his garden and helped him plant some cotton seeds all along the fence. I even earned a quarter of a rupee for using his dry composting toilet. He has been trying to promote it among the people living in ND since currently most of the rooms there are equipped with flush toilets and he finds it incredulous that we waste gallons of good water to flush down our solid waste. Moreover septic tanks, the model used to deal with toilet wastes in many places, are a pain (Heres how they work). Someone needs to clean them eventually.
His composting toilet is by design mobile. It was a simple frame with a canvas covering the on 4 sides. He digs a pit about 2 feet deep and covers the humanure with mud each time, to avoid flies. Since it is so shallow, it should not contaminate any water sources. Once it is full, he leaves it alone for about 3 months and then plants a tree at the spot! If you are really looking for alternatives, so many surface I guess! Folks interested in learning more about dry composting toilets should read Joseph Jenkins The Humanure Handbook. It is available here.
