BHOPAL: Bhopal Municipal Corporation (BMC) could save crores of rupees annually to keep the water of Upper Lake fit for drinking. The ‘bio-digester’ developed by the Defence Research and Development Organisation (DRDO) that has been installed at several places in Dal Lake in Kashmir Valley can also be used at the Upper Lake in Bhopal.
“Scientists from the DRDO have developed a ‘bio-digester’ that converts human waste into water. The Indian Railways has used it successfully, replacing traditional toilets with it. It’s also being used in Siachen and Dal Lake in Kashmir Valley,” said Arvind Tomar, defence scientist at the DRDO.
The bio-digester was innovated considering problems faced by the army at high altitudes, such as Siachen. They used soak pits for toilets, but, at sub-zero temperatures, human waste remained as it is and caused health hazards.
The DRDO developed the bio-digester that utilises anaerobic bacteria which feed upon the faecal matter inside the tank and finally degrade the matter. Army units stationed at high altitudes are now using this technique to keep the place hygienic and environment friendly.
Differences between bio-digester & STP
Comparing it with the sewage treatment plant (STP), Tomar said that the STP uses aerobic bacteria and degrades the matter in four stages. Moreover, it uses electricity, whereas the biodigester technology is environment friendly, maintenance-free and efficient without depending upon conventional energy sources. The effluent gets rid of most of the pathogens. The STP requires recurring costs to run.
The same experiment was repeated at the houseboats in Dal Lake in Shrinagar that has made the lake cleaner. “Biodigesters are now extensively used in the coastal areas to stop effluents from flowing into the sea. Now, it’s being installed at apartments, hospitals, hotels and schools, as well,” said the DRDO scientist.
Considering the population of a place, multiple units of biodigesters could be installed. The scientist said that the DRDO could be approached through phone or email by anyone interested in it, including the state government.

‘Corona could be an example of bio-warfare. If such gases, viruses or bacteria attack, the Indian Army is well-equipped to deal with it,’ said scientist Tomar
