The growing population of India’s cities are placing a huge strain on the country’s resources, especially water. Efficient management of resources is essential to countering this problem. The World Bank estimates that 21% of communicable diseases in India are related to unsafe water, most of which is contaminated either by sewage or agricultural run-off.
At GEV water contamination due to agricultural run-off is tackled through a strict zero-chemical policy for farming. Demonstrating a revolutionary technique in waste water treatment, the Soil Biotechnology (SBT) plant at GEV is a chemical-free alternative for sewage treatment. SBT consists of impervious containment and incorporates soil, formulated granular filter media and a select culture of macro organisms such as earthworms and plants. It involves a combination of physical and biological process for processing of waste water and it derives its fundamental principle from the functioning of a terrestrial ecosystem. Patented by IIT Bombay, the SBT process by design, integrates with the natural bio-geochemical cycles of nature and hence proves to be most effective eco-friendly technology for waste water treatment. The SBT plant at GEV processes up to 30,000 liters of sewage every day recycling up to 10 million litres of water annually.
