Dam Rehabilitation: Strengthening Infrastructure through Policy and Technology

1. At a Glance

India ranks 3rd globally in number of large dams with 6,628 specified dams; over 26% are >50 years old, requiring systematic rehabilitation [S1][S3].
Convergence of statutory backing (Dam Safety Act, 2021), externally-funded rehabilitation programme (DRIP), and digital tools (DHARMA, EWS) makes this a flagship infrastructure-safety issue [S1][S3][S4].
High-yield for GS-III (infrastructure, disaster management) and GS-II (statutory bodies, federalism).

PIB Backgrounder dated 15 May 2026 consolidated India's dam rehabilitation push, citing 6,628 specified dams and the role of DRIP, Dam Safety Act 2021, and DHARMA [S1].
11th meeting of National Committee on Dam Safety (NCDS) held in New Delhi, reviewing regulations and rehabilitation progress [S4].

DRIP Phase I (2012–March 2021): rehabilitated 223 dams in 7 states, World Bank-funded; closed March 2021 [S2].
Dam Safety Act enacted 2021; NCDS constituted February 2022 [S3][S4].
DRIP Phase II declared effective by World Bank in October 2021; co-financed with AIIB [S2].
Phases II & III launched as a single scheme of 10-year duration, two 6-year phases with 2-year overlap [S2].

Implementing ministry: Ministry of Jal Shakti, Department of Water Resources, RD & GR; nodal agency Central Water Commission (CWC) [S2].
Enabling law: Dam Safety Act, 2021 [S1][S3].
DRIP II + III scope: 736 dams across 19 states + 2 central agencies; outlay ₹10,211 crore (Phase II ₹5,107 cr; Phase III ₹5,104 cr) [S2].
External funding: World Bank US$250 million + AIIB US$250 million [S2].
Cost-sharing: 80:20 (Special Category States), 70:30 (General States), 50:50 (Central Agencies) [S2].
Four-tier institutional mechanism: NCDS + NDSA (Centre); SCDS + SDSO (States) [S3].
NDSA: regulatory authority; has notified 20 dam safety regulations via Gazette [S3].
NCDS: policy think-tank; 11 meetings held since constitution [S3][S4].
Section 21: mandates earmarked O&M funds by every specified dam owner [S3].
DHARMA: Dam Health and Rehabilitation Monitoring Application — digital asset-management platform [S1].

Administrative: 4-tier mechanism balances Centre-State roles; CWC is technical secretariat; states own most dams — requires cooperative federalism [S3].
Legal/Constitutional: Water is a State subject (Entry 17, List II); Centre legislated under Entry 56, List I (inter-state rivers) — Act faced federalism critique from Tamil Nadu and Kerala [S3].
Scientific/Technological: Real-time instrumentation, hydro-meteorological & seismological networks, Emergency Action Plans, Early Warning Systems, DHARMA portal for asset health [S1][S3].
Environmental/Disaster: Aims to prevent dam-failure disasters; safeguards downstream riverine ecology and population [S2].
Economic: ₹10,211 crore outlay; protects irrigation, hydropower and water-supply assets central to agrarian economy [S2].

15 May 2026: PIB Backgrounder on Dam Rehabilitation released [S1].
11th NCDS meeting held in New Delhi reviewing regulations and DRIP progress [S4].
NDSA published 20 regulations under the 2021 Act covering inspection, hazard classification, EAP, risk assessment [S3].

India is 3rd in world for number of large dams; 6,628 specified dams [S1].
>26% of Indian dams are >50 years old [S1].
DRIP-I closed March 2021, covered 223 dams in 7 states [S2].
DRIP-II declared effective by World Bank in October 2021 [S2].
DRIP-II/III: 736 dams in 19 states + 2 central agencies, outlay ₹10,211 cr [S2].
Co-financiers: World Bank + AIIB, US$250 million each [S2].
Nodal agency: Central Water Commission, under Ministry of Jal Shakti [S2].
Dam Safety Act passed in 2021; four-tier mechanism: NCDS, NDSA, SCDS, SDSO [S3].
NCDS constituted February 2022; functions as policy think-tank [S3].
NDSA has notified 20 dam safety regulations [S3].
Section 21, Dam Safety Act mandates earmarked O&M funds [S3].
DHARMA = Dam Health and Rehabilitation Monitoring Application [S1].
Cost-sharing 80:20 for Special Category States under DRIP [S2].

GS-III: Infrastructure (water resources), Disaster Management.
GS-II: Statutory bodies; Centre-State relations on water.
Possible stems:
"Examine the institutional mechanism under the Dam Safety Act, 2021. Does it adequately address federal concerns?"
"Critically evaluate DRIP's contribution to dam safety in India. What role does technology play in real-time monitoring?"
"With 26% of Indian dams over 50 years old, discuss the disaster-risk implications and policy response."

National Water Policy 2012 — overarching framework for water governance.
Inter-State River Water Disputes Act, 1956 — federal water disputes link.
NDMA & Disaster Management Act, 2005 — disaster-risk overlap.
Hydropower sector / PMKSY — dam-dependent infrastructure.
AIIB & World Bank in India — multilateral finance.
Climate change & glacial lake outburst floods (GLOFs) — Uttarakhand/Sikkim risks to dams.
Central Water Commission — institution profile.
River-linking project (NPP) — adjacent water infrastructure debate.

Dam Safety Act is 2021, not 2019 (year of Bill introduction earlier was 2018/2019).
Nodal ministry is Jal Shakti, NOT MoEFCC or Power.
DRIP-II is co-financed by AIIB + World Bank, not solely World Bank.
NCDS = policy body; NDSA = regulator — do not confuse roles.
DHARMA is an asset-management application; not to be confused with e-NWR or WRIS.
India is 3rd in large dams (after China and USA), not 2nd.
