Dam Safety Act 2021, Provisions, Objectives, Authorities, Significance

India possesses one of the largest dam networks in the world, with over 6,000 large dams supporting irrigation, drinking water supply, hydropower generation, and flood control. However, the increasing age of dams, changing climatic conditions, and absence of a uniform regulatory framework had created serious safety concerns. The Dam Safety Act, 2021 addresses this gap by establishing a comprehensive legal and institutional mechanism for surveillance, inspection, operation, and maintenance of specified dams to prevent dam-failure-related disasters.

About Dam Safety Act, 2021

The Dam Safety Act, 2021 came into force on 30 December 2021 and provides a comprehensive framework for surveillance, inspection, operation and maintenance of specified dams across the country.

A specified dam under the Act refers to a dam that is more than 15 metres in height, or between 10 and 15 metres in height if it satisfies prescribed technical criteria. The compliance of the various provisions under the Act has now become the statutory obligations of the dam owners coupled with definite timelines. 

Need for the Dam Safety Act

• India is the world’s third-largest dam-owning nation, with 6628 specified dams, of which 6,545 are operational and 83 are under construction. 
• The gross water storage capacity of these dams is about 330 billion cubic metres. They are critical for ensuring national food, energy, and water security.
• More than 26% of India’s dams are over 50 years old. This includes 291 that are more than 100 years old.  About 42% fall within the 25-50 years age bracket. This highlights the urgent need for systematic rehabilitation, structural strengthening, and safety upgrades.
• Climate change has intensified extreme rainfall events and floods, placing unprecedented stress on dam infrastructure and reservoir management systems.
• Prior to the Act, dam safety was governed mainly through administrative guidelines without a dedicated statutory framework or uniform national standards.
• Dam failures can cause catastrophic loss of life, property destruction, environmental damage, and long-term socio-economic disruption in downstream regions.
