Dr. Rajah Vijay Kumar, a Bengaluru-based scientist has made a device which can convert sewage water into drinking water while giving high-quality compost as a byproduct. He calls it the Boom Tube Resonator.

Bengaluru and other cities in India are facing acute drinking water shortage, the world’s big cities aren’t any better. To solve the water crisis, the world is looking  for solutions, recycling&reusing is seen as one of the best solutions. And what better than using sewage water as dirking water after recycling. The device made by Dr Kumar converts 10,000 litres of water from sewage every day and makes it drinkable in his campus.

It wasn’t possible to recover water from sewage until recently. India’s groundwater table is depleting and surface water is becoming undrinkable due to contaminations. Facing one of the worst drinking water crises in the world, India may need to consider this futuristic invention for a better tomorrow.

The Boom Tube Resonator developed by Dr Rajah Vijay Kumar’s team recovers drinkable water and gives high-value fertilizer as a byproduct. And it doesn’t use any chemicals or micro-organisms.

Sewage water contains excreta, urine, soaps or detergents, some of this dissolve, and some remain in a suspended state. Very small sewage particles remain in motion due to electrostatic charge (often negative), which causes them to repel each other. If the charge is neutralized, the particles collide joining together. The Boom Tube Resonator applies High-intensity wave to make it happen.

As per the Times of India reports, Dr Rajah Vijay Kumar’s team has received queries from Doha and Oman to recover 3 lakh litres per day, and from Malaysia to salvage 10 lakh litres. Singapore has also shown its interest in a large-scale project.


The Logical Indian congratulates Dr. Rajah Vijay Kumar’s team for making a futuristic invention which is very much needed in today’s time. We hope the Government takes note of it and uses this invention to help solve the water crisis in India.
