Kolkata: In India, nearly 600 million people lack access to adequate sanitation, increasing the risk of groundwater contamination. The Indian government has set the target of 100% sanitation by 2022 and is working to boost cleanliness and end open defecation in the country.
However, while building toilets across the country is the need of the hour, it is also important to pay attention to environmentally-friendly set ups and local conditions.
This bio-toilet also helps generate electricity, has won the Prime Minister’s Swachh Bharat award. The department has built a prototype. The civil engineering department of IIT-Kgp has made a bio-toilet, whose giant flush needs to be filled with 500 litres of water, which then recycles itself for a lifetime of use, which can stretch up to 15 years.
The toilet is unique because it is self-sustainable, and does not need a constant supply of fresh water like other toilets. Once the 500 litres of water are filled, it can be used by a family of five for a “lifetime”.
The National Thermal Power Corporation (NTPC), its first partner, has asked the developers to build one such toilet in rural Noida as a test case.
Odisha gets India’s first bio-toilet. And the Konkan Railway Corporation Limited (KRCL) is the first railway in the country to have installed bio-toilets on railway station platforms.
