Delhi's Drain Silt Piles Up: Environmental Crisis Looms as Disposal Sites Reach Capacity
As Delhi intensifies desilting operations to improve drainage and prevent flooding ahead of the monsoon, authorities face a new environmental challenge: the disposal of silt extracted from the city's drains. Officials report that the material, often mixed with municipal waste, poses serious ecological risks and can no longer be handled through conventional methods.
The Irrigation and Flood Control (I&FC) Department, responsible for flood-control drains across the capital, has found that traditional disposal mechanisms—such as strengthening embankments, filling low-lying areas, depositing material at landfill sites, and allowing contractors to reuse it—have reached saturation. With limited space and growing volumes, the department is exploring alternative solutions.
Environmental experts warn that the silt, contaminated with heavy metals and other pollutants, could leach into soil and groundwater if not managed properly. The situation underscores the need for sustainable waste management practices as urban infrastructure expands.
