The Delhi High Court has asked the Delhi Development Authority and the Delhi Jal Board to consider installing biotechnology-based systems to purify the “toxic” water collected near the Tughlakabad Fort area.
The suggestion came during a hearing on a PIL on a “toxic lake” that has been created in the area due to seepage of sewage from unauthorised colonies nearby. The PIL was filed last year by a resident of Tughlakabad, who alleged trees and wildlife in the area was being affected by the “toxic” water.
“You have done a good job at maintaining the wetlands at the Yamuna biodiversity park. You can do that here,” the court of Justice Badar Durrez Ahmed and Justice Sanjeev Sachdeva said.
On Wednesday, the DDA submitted satellite maps and a survey map of the area, indicating that four separate “water bodies had formed near the walls of the Tughlakabad Fort which were connected to each other by kutcha drains that carried sewage from nearby illegal colonies.

The court noted that the unauthorised colonies could not be demolished and suggested that the drain water could be used to develop the area. The DDA counsel also informed the court that the sewage drains could not be closed or diverted as it would lead to accumulation of sewage inside the colonies.
The court has now suggested that the “toxic” water can be purified using biotechnology and the surrounding areas, which include a 200-acre forest, could be developed as a wetland and park. The court asked the DDA and the DJB to “take the suggestion to the L-G” for sanction. The civic agencies have been directed to come up with a proposal by April 22.
