Dam Safety Act, 2021: One Law for Every Dam

In one meeting, officials reviewed four separate dam failures from four different states — Sikkim, Chhattisgarh, and Punjab among them. Until 2021, India had no single national law governing dam safety at all. Each state set its own rules, or none.

Timeline

• 1982: A Parliamentary Standing Committee first recommends a unified, central law on dam safety.
• 2019: A Dam Safety Bill is introduced in Parliament, after earlier draft versions in 2002 and 2010.
• 13 December 2021: The Dam Safety Act, 2021 receives Presidential assent, as Act No. 41 of 2021.
• 30 December 2021: The Act’s provisions come into force.
• 17 February 2022: The National Committee on Dam Safety and National Dam Safety Authority are formally constituted.
• 17 July 2026: The National Committee on Dam Safety holds its 12th meeting, reviewing recent dam failures across several states.

Must Know

• The Dam Safety Act, 2021 is India’s first standalone central law on dam safety. It received Presidential assent on 13 December 2021, and its provisions came into force on 30 December 2021.
• Before this Act, India had no uniform statutory framework for dam safety. Practices varied from state to state, based only on voluntary technical guidelines.
• A Parliamentary Standing Committee first recommended a unified law in 1982. Pressure built further over the long-running Mullaperiyar Dam dispute between Kerala and Tamil Nadu, over the structural safety of a dam built in 1895.
• The Act applies to “specified dams”. These are dams more than 15 metres in height. Dams between 10 and 15 metres also count, if they meet certain additional design and structural conditions.
• It creates four institutional bodies. The National Committee on Dam Safety (NCDS) sets policy. The National Dam Safety Authority (NDSA) implements that policy and resolves inter-state disputes. Each state must also set up its own State Committee on Dam Safety (SCDS) and State Dam Safety Organisation (SDSO). The SDSO carries out day-to-day surveillance and inspection.
• The NCDS and NDSA were formally constituted through a Gazette notification on 17 February 2022.
• The Act sets out penalties for non-compliance. General violations can draw up to one year’s imprisonment. This rises to two years if obstruction or non-compliance results in loss of life.

Good to Know

• As per the National Register of Specified Dams, 2025, India has 6,545 operational specified dams and 83 more under construction. Of these, 1,681 dams are already more than 50 years old.
• These dams together hold a combined live storage capacity of 253.95 billion cubic metres, as per the same 2025 register.
• The NDSA is headed by an officer not below the rank of Additional Secretary to the Government of India.
• Every specified dam’s owner must prepare an Emergency Action Plan, and complete a Comprehensive Dam Safety Evaluation and a Risk Assessment study.
• The NCDS is chaired by the Chairman of the Central Water Commission, and includes representatives from central ministries, states, and independent dam-safety experts.

Great to Know

• The gap between the 1982 recommendation and the 2021 Act is a useful reminder. Institutional reform in India can take decades, even when the underlying risk is well understood.
• The Act’s four-tier structure (NCDS, NDSA, SCDS, SDSO) splits policy-setting from day-to-day inspection. National bodies decide standards; state bodies actually watch the dams.
• “Specified dam” is a deliberately narrow legal category, not every structure that holds back water. Height and design thresholds decide which dams the Act’s mandatory obligations apply to.
• Dam safety connects directly to disaster preparedness more broadly. See WorldGeo0007 — Landslides, Cyclones and Disaster-Monitoring Technology.
• The 1895 dam at the centre of the Mullaperiyar dispute still stands today, forming the lake around which Periyar Tiger Reserve was later built. See IndGeo0095 — Periyar National Park.

Current Affairs

• Officials presented details of recent dam-related failures. These included the Teesta Stage-III dam failure in Sikkim, the Luti Tank and Rajadera dam failures in Chhattisgarh, and the Madhopur barrage failure in Punjab. (Source: PIB)
• The Committee agreed to draft a new regulation specifically on surveillance and security of specified dams, citing emerging threats to this infrastructure. (Source: PIB)
• States were asked to expedite mandatory compliances. This includes Comprehensive Dam Safety Evaluations, Emergency Action Plans, and Risk Assessment studies, all due by December 2026. (Source: PIB)
• The Committee also discussed nominating working engineers for postgraduate dam-safety programmes at IIT Roorkee and IISc Bengaluru. It explored bringing in NIT Surat, NIT Calicut, NIT Nagpur, IIT Guwahati, and NIT Shillong for further capacity-building. (Source: PIB)
