Bio-toilet launched by DRL Tezpur

By Correspondent

TEZPUR, Sept 8 � The Defence Research Laboratory (DRL/DRDO) Tezpur has launched bio-toilet, an eco-friendly and affordable sanitation technology especially for high-altitude areas, best suited for defence personnel and civilian in those areas in the northeast region.

Dr Vijay Veer, Director of DRL speaking to the media at a press meet at its Solmara campus said that the sanitation system is eco-friendly, appropriate and an affordable technology, with a one-time input of microbial inoculums bacterial solution and it works for more than 30-40 years easily.

�Recently, the DRL had a discussion with the Chief Minister of Assam, Tarun Gogoi about sanitation in Assam and about the installation of more than 20 such types of echo-friendly projects in Guwahati under the GMC,� he said adding it has a lot of advantages like wide applicability, maintenance free, effluent water pathogen free and recyclable and minimises water consumption. �It�s model is of very low cost and simple design for onsite construction and can be installed in single family apartment and community toilets.�

He further stated that the DRL has installed the same at various places in Assam including new buildings, offices and railway stations. The Ministry of Railways spends more than Rs 3.5 crore annually for the maintenance of the railway tracks. �Presently the railways have been using the bio-tank sanitation and this technology will save Rs 3.5 crore annually.� Dr Veer also said that the Railways have already started using this new system of bio-toilets. The DRL, DRDO, and the Ministry of Defence have developed this technology for human waste disposal for different climates and situations. The technology involves a specially designed tank (bio-tank), wherein anaerobic consortium of bacteria completely digests human waste at high efficiency. After biodegradation, effluent water is further filtered through a natural reed bed that improves effluent quality by totally reducing turbidity, suspended/dissolved solids and pathogenic coli-forms.

Urging local people to come forward to install such systems in the village areas, Dr Veer also said that one can combat various diseases like gastroenteritis, cholera etc., by installing such a beneficial system at a very low cost. �It is mentionable that the Ministry of Drinking Water & Sanitation, Government of India has signed an MoU with the DRDO for wide implementation of this technology, especially in rural areas,� he said.
