The Delhi Development Authority on Wednesday decided to use an innovative ‘soil bio-technology’, developed by IIT-Bombay, to meet the water requirement in Dwarka area.
“The project proposes using soil bio-technology treatment of bioremediated water, sourced from Palam drain. The technology will allow the remediated water from the drain, high in biochemical oxygen demand (BoD), to be treated and make it potable,” a senior DDA official said. Bioremediation is a waste management technique that involves the use of organisms to remove or neutralise pollutants from a contaminated site.
BoD (biochemical oxygen demand) is the amount of dissolved oxygen needed by aerobic biological organisms in a body of water to break down organic material present in a given water sample at certain temperature over a specific time period. And, the metric and can be used as a gauge of the effectiveness of waste-water treatment plants.
The pilot project would cost Rs3.75 crore, on 5000 square metres of land, and was likely to deliver water by the end of December this year and five million litres of water per day by January 2015, which is equivalent to supply from 50 tubwells, the official said. DDA vice-chairman Balvinder Kumar along with a team of engineers and senior officers today assessed the proposal and the urban body has decided to take up the project.
