Navigating Through Water Conflicts: Legal Resolutions and Disputes

Water has always been the lifeblood of Indian agriculture, livelihoods, and rural communities. But when rivers cross state boundaries, they carry with them the seeds of some of India’s most persistent and politically charged disputes. Inter-state water conflicts have been a defining feature of Indian federalism – pulling states into decades-long legal battles, triggering street protests, and challenging the limits of our constitutional machinery. Understanding how the law responds to these conflicts is essential not just for legal scholars, but for anyone who wants to grasp how India manages its most precious natural resource.

The constitutional backdrop: who controls water? 🔗

Water governance in India operates on a split constitutional foundation. Under Entry 17 of the State List, states have legislative authority over water supply, irrigation, canals, drainage, and water storage. This makes water primarily a state subject. However, Entry 56 of the Union List gives Parliament the power to regulate and develop inter-state rivers and river valleys when it declares such regulation to be in the public interest. This creates an inherent tension – states claim sovereignty over rivers that flow through their territory, while the Centre asserts authority over rivers that cross multiple boundaries.

Article 262 of the Constitution is the key provision here. It empowers Parliament to make laws for the adjudication of disputes relating to the use, distribution, or control of waters of any inter-state river or river valley. Crucially, it also allows Parliament to bar the jurisdiction of the Supreme Court or any other court in such matters – a unique carve-out that underscores how sensitive water disputes are treated under Indian law.

The Inter-State River Water Disputes Act, 1956 🔗

Acting on Article 262, Parliament enacted the Inter-State River Water Disputes (ISRWD) Act, 1956 – the primary legislative tool for resolving water conflicts between states. The Act lays out a clear process: when a state government requests the Centre to refer a water dispute to a tribunal, and the Centre is of the opinion that the dispute cannot be settled by negotiations, it must constitute a Water Disputes Tribunal within one year of receiving the request.

The tribunal consists of a Chairman and two other members, all nominated by the Chief Justice of India from sitting judges of the Supreme Court or High Courts. The tribunal investigates the dispute, receives evidence, and must deliver its award within three years – extendable by two more years in unavoidable circumstances. Once the Central Government publishes the award in the Official Gazette, the award carries the same force as a Supreme Court decree under Section 6(2) of the Act. This makes it binding on all parties.

The Act was significantly amended in 2002 based on recommendations of the Sarkaria Commission. The amendments introduced time limits for tribunal constitution and decision-making, and allowed parties to seek clarification of awards within three months of issuance if implementation did not begin promptly.

Landmark tribunal awards that shaped water policy 🔗

The Krishna Water Disputes Tribunal (1969) 🔗

India’s first inter-state water disputes tribunal was the Krishna Water Disputes Tribunal (KWDT-I), constituted in 1969 under Justice R.S. Bachawat. It adjudicated a dispute between Karnataka, Andhra Pradesh, and Maharashtra over the waters of the Krishna river. The tribunal’s 1973 award, published in the Gazette in 1976, determined that the total water available for distribution at 75% dependability was 2060 TMC (thousand million cubic feet), which was allocated proportionately among the three states. This award became a foundational reference point for water allocation in peninsular India. A second Krishna tribunal (KWDT-II) was constituted in 2004 and delivered its verdict in 2010, with proceedings further complicated after Telangana was carved out as a separate state and became a fourth claimant in the basin.

The Narmada Water Disputes Tribunal (1969) 🔗

The Narmada Water Disputes Tribunal (NWDT), also constituted in 1969, resolved one of independent India’s most complex river disputes – involving Gujarat, Maharashtra, Madhya Pradesh, and Rajasthan. After a decade of deliberations, the NWDT delivered its final award in 1979. It not only allocated water shares but also set the height of the Sardar Sarovar Dam and provided for a review mechanism. The Narmada tribunal remains significant because it demonstrated how a multi-state, multi-use dispute could be comprehensively resolved through an institutional process, even if the implementation of the dam project itself continued to be contested for decades.

The Cauvery Water Disputes Tribunal (1990) 🔗

No water dispute in India has generated more political heat and legal complexity than the Cauvery dispute. Negotiations between Tamil Nadu and Karnataka stretched across decades, with 26 rounds of talks between 1968 and 1990 failing to produce an agreement. The Cauvery Water Disputes Tribunal was finally constituted in 1990 after a Supreme Court direction. It issued an interim award in 1991 and its final award in 2007, allocating 419 TMC annually to Tamil Nadu, 270 TMC to Karnataka, 30 TMC to Kerala, and 7 TMC to Puducherry. The award was published in the Official Gazette only in 2013 – a six-year gap itself reflective of the political difficulties surrounding implementation. The Supreme Court subsequently modified the allocation in its landmark 2018 judgment, after which the Cauvery Water Disputes Tribunal was formally dissolved in July 2018. The Cauvery case set important precedents: it confirmed that tribunals under the ISRWD Act can grant interim relief, and it clarified that state legislatures cannot enact laws that override or preempt tribunal orders.

The limitations of riparian rights in modern water disputes 🔗

Indian water law has historically rested on the doctrine of riparian rights, inherited from English common law and codified partly through Section 7 of the Indian Easements Act, 1882. A riparian owner – someone who owns land adjoining a river or stream – has the right to access the water flowing past their land in its natural flow, quantity, and purity. These rights are natural rights, not acquired by statute, and they cannot ordinarily be extinguished unless adversely enjoyed by another over time.

Courts have upheld riparian rights in several significant cases. In M.C. Mehta v. Union of India (the Ganga Pollution Case), the Supreme Court recognized the petitioner’s standing as a riparian owner whose rights were being violated by river pollution, and admitted the petition as a Public Interest Litigation. In Vippalapati v. Raja Vizianagram, the court confirmed that riparian rights include the right to access freely flowing water without obstruction, including obstruction by a dam.

However, in recent times the riparian rights doctrine has increasingly been questioned as an appropriate basis for resolving modern water disputes. The doctrine has several inherent limitations when applied at scale. First, it is land-centric – it protects only those who own land adjacent to the water body, leaving non-riparian communities (including most urban populations and downstream agricultural users drawing from canals) without a clear legal claim under this framework. Second, riparian rights are use-neutral – they do not prioritize water for drinking or basic human needs over industrial use. Third, in the context of inter-state disputes, the doctrine becomes practically unworkable: entire states cannot be treated as riparian owners in any meaningful sense, and the principle of natural flow gives no guidance on how to divide a shared resource equitably between political units.

India’s water governance has increasingly shifted toward treating water as a public trust – a resource held by the state on behalf of all citizens, rather than a private right attached to land ownership. The public trust doctrine, recognized by Indian courts, places limitations on how riparian rights can be exercised and opens the door for state regulation in the broader public interest. This shift is reflected in the ISRWD Act itself, which treats river water as a shared national resource to be distributed on principles of equitable and reasonable use – not simply on the basis of who owns land along the bank.

Judicial interventions and the role of the Supreme Court 🔗

While the ISRWD Act technically bars the jurisdiction of courts over matters decided by water tribunals, the Supreme Court has found ways to remain actively involved in water disputes – primarily through Article 136 (Special Leave Petitions) and Article 32 (right to constitutional remedies, particularly when Article 21 right to life is implicated). States have regularly approached the Supreme Court challenging tribunal awards, seeking enforcement of interim orders, and contesting the implementation machinery.

The Central Water Commission plays a supporting role by collecting hydrological data and assisting tribunals, but the absence of an authoritative, commonly accepted data set on river flows has been repeatedly flagged as a structural weakness in the adjudication process. When states dispute the very baseline figures for water availability, tribunal proceedings become protracted adversarial battles rather than technical determinations.

The ISRWD Amendment Bill, 2017 proposed significant reforms – including a single permanent tribunal to replace the multiple ad hoc bodies, a Dispute Resolution Committee (DRC) to attempt negotiated settlement within 18 months before any tribunal reference, and a centralized national data bank for river basin information. These proposals acknowledge that the current framework, while functional, is too slow and too adversarial to keep pace with growing water stress across the country.

Why water conflicts persist despite legal frameworks 🔗

Several structural factors explain why legal machinery alone has not been enough to resolve India’s water disputes permanently. As scholars of cooperative federalism have noted, water conflicts in India are dealt with more politically than scientifically – environmental, social, and cultural dimensions of rivers are often sidelined in favour of volume-based allocation battles. The shift from a deliberative to an adversarial approach in tribunal proceedings has extended litigation timelines and deepened political entrenchment around water sharing.

India has 18% of the world’s population but only about 4% of its global freshwater resources, with deeply uneven spatial distribution. Upstream states have strong incentives to build storage infrastructure; downstream states have equally strong incentives to resist it. Climate variability is making seasonal flows less predictable, reducing the reliability of fixed allocations made by tribunals decades ago. And as urban and industrial demand grows alongside agricultural use, the already over-committed water budgets of most major river basins are under increasing strain.

The Ravi and Beas Water Tribunal, constituted as far back as 1986, had still not delivered a final report nearly four decades later – a sobering reminder that even the legal mechanism designed to resolve these disputes can itself become a site of indefinite delay. The tribunal system’s composition, drawn exclusively from the judiciary without mandatory technical or environmental expertise, has also been criticized for producing awards that are legally sound but hydrologically contestable.

What do you think? Given that riparian rights were designed for a world of individual landowners rather than competing states, should India adopt a completely new statutory framework for water allocation – one built on equitable use and ecological sustainability rather than land-based entitlement? And with climate change making historical flow data increasingly unreliable, how should tribunals be empowered to make forward-looking, adaptive water allocation decisions rather than locking states into fixed numerical quotas?
