Decentralised Waste Water Treatment


From water to water

Look out of the window the next time you travel by road or by train anywhere in India. Hit a human settlement, and you will see, heaps of plastic coloured garbage apart, pools of dirty black water and drains that go nowhere. They go nowhere because we have forgotten a basic fact: if there are humans, there will be excreta. Indeed, we have also forgotten another truth about the so-called modern world: if there is water use, there will be waste. Roughly 80 per cent of the water that reaches households flows out as waste.

Excreta's economy: a true experience

Every society must understand how the excreta it produces is managed. It teaches us many things about water, about waste, about technologies to clean, economics and politics: of who is subsidised to defecate in our societies. But, most importantly, it teaches us humility. We know so little about our own world. If we knew better, we would understand why we are failing to ensure our present and why we will all need to do things differently, if we want to safeguard our future.
