1. The Prime Minister's Role as Ex-Officio Chairman (basic)
In the Indian politico-administrative system, the Prime Minister (PM) serves as the
Ex-Officio Chairman of several high-level bodies. The term
'Ex-Officio' is a Latin phrase meaning 'by virtue of one’s office.' This means that the person holding the office of the Prime Minister automatically becomes the chairperson of these specific organizations without needing a separate appointment for those roles. This design ensures that these apex bodies have the highest level of political authority and can facilitate effective coordination between different ministries and between the Centre and the States
Indian Polity, M. Laxmikanth(7th ed.), Chapter 20: Prime Minister, p.209.
The bodies chaired by the Prime Minister are usually those that deal with national security, strategic planning, and federal cooperation. These include:
- NITI Aayog: The premier policy 'Think Tank' of the Government of India, which replaced the Planning Commission.
- National Integration Council (NIC): A body that addresses issues like communalism, casteism, and regionalism Introduction to the Constitution of India, D. D. Basu (26th ed.), ADMINISTRATIVE RELATIONS BETWEEN THE UNION AND THE STATES, p.401.
- Inter-State Council (ISC): A constitutional body (under Article 263) that supports coordination between the Union and the States.
- National Water Resources Council (NWRC): The apex body that decides on national water policy and planning.
By heading these councils, the Prime Minister acts as the 'Crisis manager-in-chief' and the chief spokesperson of the Union Government. This positioning allows for a 'top-down' approach in policy formulation, ensuring that national priorities are reflected in the decisions of these diverse regulatory and advisory bodies Indian Polity, M. Laxmikanth(7th ed.), Chapter 20: Prime Minister, p.209.
Key Takeaway The Prime Minister’s ex-officio chairmanship of bodies like NITI Aayog and the National Water Resources Council provides these organizations with the political weight necessary for inter-departmental and federal coordination.

2. Constitutional Status of Water: Union vs State Lists (basic)
In the architecture of the Indian Constitution, the management of water is a delicate balancing act between the Union and the States. Primarily,
Water is a State subject. Under
Entry 17 of the State List (List II), State governments have the authority over water supplies, irrigation, canals, drainage, embankments, water storage, and water power. This ensures that states can tailor their water management to local geography and agricultural needs
Introduction to the Constitution of India, DISTRIBUTION OF FINANCIAL POWERS, p.384.
However, because rivers frequently flow across state boundaries, the Union Government is given a specific oversight role. Entry 56 of the Union List (List I) empowers the Central Government to regulate and develop inter-State rivers and river valleys, provided that Parliament declares such regulation to be in the public interest. To operationalize this power, Parliament enacted two critical pieces of legislation in 1956: the River Boards Act and the Inter-State River Water Disputes Act Indian Polity, Inter State Relations, p.167. These laws allow the Center to create advisory boards for river valleys and set up specialized tribunals to resolve conflicts between states.
The constitutional framework also includes a unique "safety valve" for disputes. Under Article 262, Parliament has the power to adjudicate any dispute regarding the use or distribution of inter-state waters. Notably, this Article allows Parliament to exclude the jurisdiction of the Supreme Court and any other court over such disputes, leading to the creation of various Water Disputes Tribunals, such as those for the Krishna and Godavari rivers Indian Polity, Inter-State Relations, p.168. To coordinate policy at the highest level, the National Water Resources Council (NWRC) serves as the apex body. Chaired by the Prime Minister, it ensures that despite the legal division of powers, there is a national consensus on water policy Indian Polity, Prime Minister, p.209.

3. Evolution of Water Governance: The Ministry of Jal Shakti (intermediate)
Historically, water management in India was fragmented across several departments, leading to a 'siloed' approach where irrigation, drinking water, and river conservation were handled separately. To address this, the government transitioned towards
Integrated Water Resources Management (IWRM). The landmark step in this evolution occurred in May 2019 with the creation of the
Ministry of Jal Shakti. This new entity was formed by merging two existing ministries: the
Ministry of Water Resources, River Development and Ganga Rejuvenation and the
Ministry of Drinking Water and Sanitation. This consolidation allows for a holistic 'source-to-tap' approach to the water cycle.
At the peak of India's water governance hierarchy sits the
National Water Resources Council (NWRC). This is an apex body responsible for evolving a national consensus on water policy. Crucially, the NWRC is
chaired by the Prime Minister, while the Union Minister for Jal Shakti serves as the Vice-Chairman
Indian Polity, M. Laxmikanth(7th ed.), Chapter 20, p.209. This high-level leadership ensures that water issues are treated as a matter of national priority, facilitating coordination between the Union and the States.
Beyond policy, the Ministry acts as the
nodal agency for several flagship schemes. For instance, while the
Pradhan Mantri Krishi Sinchayee Yojana (PMKSY) was originally launched under the Ministry of Agriculture, the Ministry of Jal Shakti was designated as the nodal ministry in 2016 to expedite the completion of major irrigation projects under the motto
'Har Khet Ko Paani' Indian Economy, Nitin Singhania .(ed 2nd 2021-22), Irrigation in India, p.369. Furthermore, the ministry spearheads the
Namami Gange program, which focuses on maintaining
'Nirmal Dhara' (unpolluted flow) and
'Aviral Dhara' (continuous flow) through sewerage infrastructure and ecological rejuvenation
Environment, Shankar IAS Acedemy .(ed 10th), Aquatic Ecosystem, p.60.
1983 — Establishment of the National Water Resources Council (NWRC).
2016 — Ministry of Water Resources becomes the nodal ministry for PMKSY.
2019 — Formation of the Ministry of Jal Shakti through a major departmental merger.
Key Takeaway The Ministry of Jal Shakti represents a move toward integrated water governance, overseen by the Prime Minister via the NWRC, to manage everything from irrigation and drinking water to river rejuvenation under one roof.

4. Inter-State Water Disputes and Tribunals (intermediate)
In a federal setup like India, where rivers often flow through multiple states, water becomes more than just a resource—it becomes a point of contention. To manage this, the Constitution provides a unique framework under
Article 262. This article empowers Parliament to provide for the adjudication of disputes relating to the use, distribution, or control of waters of any inter-state river. Most notably, it allows Parliament to exclude the jurisdiction of all courts, including the
Supreme Court, over such disputes
Introduction to the Constitution of India, INTER-STATE RELATIONS, p.407. This is a rare instance where the apex court's reach is limited to ensure that technical and political water issues are handled by specialized bodies rather than traditional litigation.
Following this constitutional mandate, two critical laws were enacted in 1956. The first is the
River Boards Act, which allows the Central Government to set up boards to advise states on the regulation and development of inter-state rivers. However, these boards are largely advisory. The second is the
Inter-State River Water Disputes Act, which empowers the Centre to establish an
ad hoc tribunal when a state government requests it and negotiations fail
Indian Polity, Inter-State Relations, p.167. Once a tribunal delivers its award, it is final and binding on all parties involved.
| Feature | River Boards Act, 1956 | Inter-State River Water Disputes Act, 1956 |
|---|
| Primary Function | Advisory and Planning | Adjudication and Dispute Resolution |
| Nature of Decision | Recommendatory | Final and Binding |
| Trigger | Request by State or Central Initiative | Request by State when negotiations fail |
At the apex of this regulatory structure is the
National Water Resources Council (NWRC). This body is responsible for formulating the National Water Policy and ensuring a holistic approach to water management across the country. To reflect its high strategic importance, the council is chaired by the
Prime Minister, with the Union Minister of Water Resources serving as the Vice-Chairman
Indian Polity, Prime Minister, p.209. Despite these mechanisms, disputes remain frequent and intense—such as the
Cauvery dispute in the south or the
Narmada dispute in the west—testing the 'cooperative spirit' of our federal system
Indian Constitution at Work, FEDERALISM, p.169.
Key Takeaway Under Article 262, Parliament can create binding tribunals for water disputes and specifically bar the jurisdiction of the Supreme Court to ensure specialized resolution.

5. National Water Policy (NWP) Framework (exam-level)
To understand water governance in India, we must start with its constitutional paradox: Water is primarily a State subject, yet the planning and management of inter-state rivers require a unified national vision. To bridge this gap, the Government of India established the National Water Resources Council (NWRC) as the apex body for policy formulation. Crucially, the NWRC is chaired by the Prime Minister, with the Union Minister of Water Resources serving as the Vice-Chairman and Chief Ministers of all states as members. This high-level composition ensures that the National Water Policy (NWP) carries the political weight necessary to harmonize diverse state interests M. Laxmikanth, Prime Minister, p. 209.
The evolution of India's water strategy has seen three major iterations, each reflecting the challenges of its time. The latest framework, the National Water Policy 2012, introduced a paradigm shift by advocating for a National Water Framework Law. This policy moves beyond mere infrastructure to focus on demand management and efficiency. A standout feature is the treatment of water (after meeting basic needs like drinking and food security) as an economic good. This is intended to reflect its scarcity and encourage conservation through rationalized tariffs and water auditing NCERT 2025 ed., Water Resources, p.50.
1987 — Adoption of the first National Water Policy to provide a framework for planning and development.
2002 — Revised policy emphasizing integrated water resource management and participatory approaches Majid Husain, Regional Development and Planning, p.29.
2012 — Current policy emphasizing climate change adaptation, water footprints, and the "economic good" principle Majid Husain, The Drainage System of India, p.45.
Modern water policy also places ecological needs at the forefront. The NWP 2012 mandates a "minimum eco-system flow" to ensure rivers remain healthy even after human extractions. It also encourages community participation in managing water projects, moving away from a top-down bureaucratic model to a more localized, sustainable approach. This includes a focus on adaptation strategies for climate change, ensuring that water structures are resilient to the increasingly erratic monsoon cycles NCERT 2025 ed., Water Resources, p.50.
Key Takeaway The National Water Policy (NWP) framework, guided by the PM-led National Water Resources Council, seeks to balance water as a social right for survival with its role as an economic resource for sustainable development.

Laxmikanth (7th ed.), Prime Minister, p.209
6. The National Water Resources Council (NWRC): Composition (exam-level)
In the complex landscape of Indian governance, water is primarily a State subject, yet its management often requires a national perspective due to the inter-connectedness of river basins across borders. To bridge this gap, the National Water Resources Council (NWRC) was established as the apex body for evolving a unified national policy for the development and management of water resources. Think of it as the high-level deliberative forum where the Union and the States come together to decide the future of India's water security.
The composition of the NWRC reflects its apex status and the gravity of the subject. It is chaired by the Prime Minister of India, which underscores that water policy is treated as a matter of highest national priority Indian Polity, M. Laxmikanth, p.209. To ensure functional continuity and specialized oversight, the Union Minister of Water Resources (now known as the Minister of Jal Shakti) serves as the Vice-Chairman of the Council. This dual leadership ensures that the body has both political weight and technical focus.
The council is a true federal body. Its membership includes:
- Union Ministers: Heads of relevant portfolios such as Agriculture, Power, Environment, and Rural Development.
- State Representatives: The Chief Ministers of all States and the Administrators/Lieutenant Governors of Union Territories.
- Secretary Support: The Secretary of the Ministry of Water Resources acts as the Secretary of the Council.
By bringing the heads of the State executives (Chief Ministers) to the same table as the Prime Minister, the NWRC facilitates the approval of critical documents like the National Water Policy, which aims to provide a framework for integrated water resource development and conservation INDIA PEOPLE AND ECONOMY, NCERT 2025, p.50. This ensures that the policy isn't just a central directive but a consensus-driven roadmap for the entire country Geography of India, Majid Husain, p.45.
Key Takeaway The National Water Resources Council is the highest policy-making body for water in India, chaired by the Prime Minister and comprising all State Chief Ministers to ensure a federal consensus on water management.

7. Solving the Original PYQ (exam-level)
Now that you have explored the Prime Minister's multifaceted role as the head of the Union government, this question serves as a perfect application of those concepts. In the Indian administrative architecture, the Prime Minister is not merely the leader of the Cabinet but also the ex-officio chairman of several apex bodies that require high-level inter-ministerial and center-state coordination. As you learned in Indian Polity, M. Laxmikanth, the National Water Resources Council (NWRC) fits into this category of high-stakes policy organizations where the PM's authority is needed to navigate complex national interests.
To arrive at the correct answer, (A) Prime Minister, you must look past the specific department and identify the hierarchy of leadership. A common UPSC trap is to present the departmental minister, such as the Minister of Water Resources (Option B), as the primary choice. While it is intuitive to link the subject of water to its specific ministry, in this council's structure, the Union Minister for Water Resources actually serves as the Vice-Chairman. Options (C) and (D) are distractors involving related but distinct portfolios. Remember: when a council involves making national policy and coordinating between multiple states, it is almost invariably chaired by the Prime Minister to ensure executive weight and political consensus.
