NGT orders review of city’s drainage system

The petitioner in the case, had said drains that were once tributaries of the river were now being used to carry sewage.

The National Green Tribunal (NGT) has asked an expert committee to review Delhi’s drainage system and rely on a drainage map made in 1976, while concluding how many drains in Delhi are man-made.

Previously, the expert committee had told the tribunal that almost 46 per cent of Delhi — effectively 4.5 million people — don’t have a proper sewerage system. The NGT had sought the advice of professor

A K Gosain of Department of Civil Engineering at IIT-Delhi on the maintenance and preservation of stormwater drains in order to reduce pollution in the Yamuna.

Manoj Mishra, the petitioner in the case, had said drains that were once tributaries of the river were now being used to carry sewage.
