  • Dam Safety Act
  • What are the provisions of the Act?
  • What are the challenges?
  • How is dam safety undertaken?

Why in news?

  • India has almost 6,000 large dams and about 80% of them are more than 25 years old and carry safety risks.
  • A new Dam Safety Act (DSA) was passed in late 2021.
  • On October 4, 2023, a glacial lake outburst flood (GLOF) in North Sikkim’s South Lhonak Lake washed away one of the biggest hydropower projects in India, the Teesta III dam at Chungthang.
  • Reports have since revealed there were no early warning systems, no risk assessment or preventive measures in place as required under the Act.

What are the provisions of the Act?

  • About
    • The Dam Safety Act was tabled in the Rajya Sabha in December 2021, as a response to deficient surveillance and maintenance causing dam failure-related disasters.
    • The Act listed key responsibilities and mandated that national and State-level bodies be established for implementation.
  • Key provisions
    • A National Committee on Dam Safety would oversee dam safety policies and regulations;
    • A National Dam Safety Authority would be charged with implementation and resolving State-level disputes;
    • The Chairman of the Central Water Commission (CWC) would head dam safety protocols at the national level;
    • A State Committee on Dam Safety (SCDS) and State Dam Safety Organisation (SDSO) would be set up.
  • Obligations of States
    • Provisions require States to:
      • classify dams based on hazard risk,
      • conduct regular inspections,
      • create emergency action plans,
      • institute emergency flood warning systems, and undertake safety reviews and period risk assessment studies.
    • States were asked to report and record incidents of dam failures.
      • Until now, no statutory provision required systemic reporting of failures and no single agency was tasked with tracking this data.
      • The CWC keeps a record but the list is not updated regularly.
  • Punishment
    • Failure to comply with any provision of the Act is punishable with imprisonment and/or fines.
    • If such obstruction or refusal to comply with directions results in loss of lives or imminent danger, the entity shall be punishable with imprisonment for a term which may extend to two years.
      • In February 2023, the Sikkim High Court ordered the Gati Hydropower Project company to pay ₹70 lakh to two widowed mothers, for non-compliance with the Dam Safety Act.

What are the challenges?

  • Blind spots in both legislation and implementation
    • The DSA does not promote risk-based decision-making and fails to incentivise transparency.
    • The frequency and scale of such disasters reveal a pattern of neglect.
  • Access of information
    • A robust DSA should allow different stakeholders to access information easily, but India’s framework falls short.
      • Dam safety is a public purpose function.
      • Everything about dam safety, functions of all the institutions and committees and authorities, their reports, decisions minutes and agendas, everything should be promptly available to the public.
      • However, nothing is in the public domain.
  • Lack of periodic review
    • Periodic reviews are often not conducted or if they are, their findings are not easily available in the public domain.
    • The Act requires dam builders to conduct comprehensive dam safety evaluations. However, there is no standardisation of how the failure is analysed and reported.

How is dam safety undertaken?

  • Dam safety is a function of many parts
    • This includes:
      • designing and constructing dams that adhere to safety margins,
      • maintaining and operating them per guidelines,
      • recording data in real-time in an accessible format,
      • forecasting hazardous events and instituting emergency plans, etc.
  • Hazard profiling and regular assessment mandated by the Act
    • Hazard risk fluctuates at the slightest touch, responding to climate change, urbanisation, and the way people/companies use water or where they are located.
    • Periodic reviews are expected to bring forth fresh inundation maps and new rule curves (which determine the capacity of dam reservoirs).
    • All of these contribute towards the safety of the downstream areas.
