Zero-Power Sewage Plants that Mimic Cows’ Digestive System
The wastewater dumping issue is a major sanitation issue in many countries, especially in third-world countries. Studies suggest that about 80% of the world’s wastewater gets dumped untreated.
For example, wastewater dumping issue is quite severe in Bangalore, India. Here, a large quantity of wastewater gets dumped in the lakes.
Modern sewage plants are quite expensive to run and poorer countries find it hard to spend that much money.
Tharun Kumar, a Bangalore resident found a creative solution to this nasty problem. He sought out help from Biomimicry Institute and developed a wastewater treatment plant based on the digestive system of cows.
The modern treatment plants have a certain type of bacteria that breaks down the waste with the help of bacteria. But these bacteria need oxygen to survive too. That’s why the treatment plants need expensive blower motors.
Cows’ digestive system contains a similar bacteria chamber and they don’t need oxygen to survive.
Kumar’s idea was to design a new kind of sewage system that follows the same design principle. Plus, this sewage system doesn’t even need electrical power as the wastewater gets feed through the chamber with the help of gravity.
So far, Kumar’s company ECOSTP has built 50 sustainable sewage plants in different parts of India and plans to build more in Africa too.
