Data on old dams
234 large dams in India are 100 years old – and still functional
Dams are normally designed for approximately 100 years of useful age
National Register of Large Dams 2019
Functional life gets decreased with progressive reservoir sedimentation
Why discuss Dams?
Human displacement
Water scarcity
Environmental damage
Seismic activity
Cost overruns
Social Impacts
of Dams
Environmental Impacts
Economic Impacts
Cultural loss
Health Impacts due to water bodies
Dismay over resettlement
Woes of Ageing Dams
Structurally vulnerable dams
Seismically sensitive
Freuency and severity of flooding and other extreme environmental events
Lack of storage information
Soil replaces the water in the reservoirs, causing the storage capacity to decrease
Consequences of
Ageing Dams
Crop yields may get affected severely, this can disrupt the farmer’s income
No or Low cushion against floods
Supply gets choked, leading to less and less water for cropped areas
Persistent threats of breakdown
Soil replaces the water in reservoirs
Policy measures so far
Dam Safety Act, 2021
Dam Rehabilitation and Improvement Project (DRIP)
Way forward
Accountability and Transparency
Operational safety and drills
Decommissioning
Cumulative Assessment
Timely reviews
