| India’s first Toilet to Tap project ‘Sujala Dhara’ was set up by DJB in collaboration with Delhi-based not for profit organization SANA, uses a chemical and organic filtration system that can produce 80,000 litres of treated water per day. The bio-filter plant associated with Sujala Dhara project uses worms for treating the wastewater, which helps in producing nutrient rich treated water. The plant is powered by solar energy, reducing operating costs and boosting its green quotient. It is also possible to run this solar powered plant all day long using battery backup. | ||||||||||||||||||||||||||||

The plant receives water from the Keshopur drain. At first the water from the sewage pit goes to a bio filter bed that has layers of organic and inorganic material such as earthworms, plants, cotton extract, bacteria, sand and pebbles. The water then goes through a feeding tank into the sand filter and finally through a nano- filter membrane, measuring 0.001 micron. The reject water from this plant amounts to just 15 percent of the raw water and is rich in nutrients like potassium and nitrogen, which can be used as a liquid fertilizer. |
