1. Introduction
The Dam Safety Act, 2021 mandates a proactive and accountable framework for dam management, recognizing that dam owners—whether public or private—play the most direct role in ensuring the structural and operational safety of dams. The Act clearly defines the legal and operational responsibilities of dam owners, placing them at the center of compliance, maintenance, and risk mitigation.
2. Obligations of Dam Owners under the Act
Under the provisions of the Dam Safety Act, 2021, all dam owners are legally bound to:
- Ensure the safe design, construction, operation, and maintenance of specified dams.
- Comply with the guidelines and standards issued by the National Dam Safety Authority (NDSA) and State Dam Safety Organizations (SDSOs).
Prepare, implement, and regularly update:
- Operation and Maintenance (O&M) Manuals
- Emergency Action Plans (EAPs)
- Instrumentation protocols and data sharing
- Submit all required documents and inspection reports to the State Committee on Dam Safety (SCDS) and NDSA.
- Facilitate routine inspections, audits, and post-event evaluations (e.g., after floods or earthquakes).
Failure to meet these obligations may result in penalties, operation restrictions, or enforcement action by the authorities.
3. Establishment of Dam Safety Units (DSUs)
Each dam-owning agency is required to establish a Dam Safety Unit (DSU), which functions as the in-house safety and compliance wing of the owner’s organization.
Key Functions of the DSU:
- Conduct daily surveillance and ensure timely detection of any structural or operational anomalies.
- Maintain instrumentation logs, analyze readings, and flag safety concerns.
- Oversee and record all repairs, upgrades, and retrofitting activities.
- Liaise with SDSO and SCDS during inspections and compliance audits.
- Ensure record-keeping of structural drawings, safety reports, and historical modifications.
This internal unit is responsible for integrating dam safety into day-to-day operations, not just during crisis scenarios.
4. Responsibilities for Safe Construction, Operation, and Maintenance
Dam owners must ensure:
- Structural integrity is maintained through regular inspections and adherence to design standards.
- Hydrological safety by calibrating spillway gates, flood routing, and discharge protocols.
- Mechanical reliability of gates, valves, and power mechanisms through preventive maintenance.
- Seismic safety through structural reviews in earthquake-prone zones.
- Security protocols are in place for sabotage prevention and emergency access.
Owners must also adopt technological advancements such as SCADA systems, telemetry, and automated alarm systems.
5. Financial Provisions for Dam Safety
Owners are obligated to make dedicated financial allocations for:
- Regular operation and maintenance
- Periodic inspections and instrumentation
- Staff training and capacity building
- Safety upgrades and emergency preparedness
- Hiring external consultants or audit experts when needed
The Dam Safety Act encourages advance budgeting for dam safety as a capital and operational expenditure, not an ad hoc expense.
6. Regular Inspections and Risk Assessments
Dam owners must:
- Facilitate annual technical inspections and post-event inspections.
- Conduct risk assessment studies for potential failure scenarios and their downstream impact.
- Share data with authorities including siltation studies, seepage analysis, and hydrological evaluations.
Risk classification (e.g., low, moderate, high hazard potential) is also to be maintained and revised based on inspection findings.
7. Operation & Maintenance (O&M) Manuals
Each dam must have a comprehensive O&M Manual, prepared in accordance with national standards.
Manual Contents Include:
- Structural drawings and specifications
- Details of spillway, gates, and mechanical systems
- Routine and preventive maintenance schedules
- Emergency procedures for operational failures
- Contact details for dam staff and emergency responders
These manuals must be reviewed and updated every five years or after any major repair/incident.
8. Conclusion
The Dam Safety Act, 2021 elevates dam owners to the role of primary custodians of dam integrity and public safety. Through the establishment of Dam Safety Units, clear obligations for inspections and O&M practices, and dedicated financial provisions, the Act creates a robust accountability structure. Compliance not only ensures legal adherence but also builds resilience against natural and operational threats, safeguarding lives, livelihoods, and infrastructure investments.
