The sound that echoed through Bansilalpet in Hyderabad was not merely applause for a heritage restoration project. It was the sound of a community confronting the unthinkable prospect that one of the world’s fastest growing economies is edging towards systemic water insecurity. When clean water began to collect once again in the seventeenth century Bansilalpet stepwell after eighteen months of excavation and removal of three thousand tonnes of refuse, it marked more than architectural revival. It signified a rare instance in which historical infrastructure outperformed modern policy complacency.
For four decades the Bansilalpet stepwell had functioned as a dumping ground rather than a lifeline. Residents such as Hajira Adeeb had witnessed its transformation from community water source to repository of neglect. Its restoration, led by architect Kalpana Ramesh with the support of the Telangana Municipal Administration and Urban Development Department and the social enterprise Rainwater Project, has now resulted in a sustained water depth of approximately nine metres even during summer months. In a region confronting acute groundwater stress, that figure is not anecdotal. It is politically and legally consequential.
India houses more than 1.4 billion people, nearly eighteen per cent of the global population, yet possesses roughly four per cent of the world’s fresh water resources. According to the Government of India policy think tank NITI Aayog, more than six hundred million citizens face high to extreme water stress. The Central Ground Water Board has warned that several states including Punjab, Haryana, Delhi, Uttar Pradesh, Rajasthan, Gujarat, Tamil Nadu, Karnataka, Andhra Pradesh and Telangana are experiencing levels of groundwater extraction that are unsustainable and in certain districts approaching conditions colloquially referred to as day zero. In international relations terms, this is not a domestic inconvenience. It is a strategic vulnerability with implications for food security, internal migration, regional stability and compliance with global environmental obligations.
The revival of stepwells must therefore be analysed not as nostalgia but as adaptive governance. Stepwells, built predominantly between the eleventh and eighteenth centuries, were engineered to capture monsoon rainfall and enable percolation into natural aquifers. Thousands once dotted the subcontinent. The Stepwell Atlas compiled by researchers and organisations including the Indian National Trust for Art and Cultural Heritage identifies more than three thousand surviving structures, with approximately one hundred located in Telangana and nearly half of those in Hyderabad. Their abandonment during British colonial administration, which deemed them unhygienic, combined with post independence urbanisation and waste dumping, accelerated their decline.
Prominent examples such as Chand Baori, Rani ki Vav and Agrasen ki Baoli have been preserved as architectural heritage sites. Rani ki Vav holds recognition as a UNESCO World Heritage Site. Yet these restored monuments function largely as tourist attractions rather than active water infrastructure. The Bansilalpet project is distinct because it reactivates hydrological utility, not merely aesthetic appreciation.
The legal architecture governing water in India complicates reform. Water is constitutionally listed as a state subject under the Seventh Schedule of the Constitution of India, granting primary legislative competence to individual states. However, groundwater regulation intersects with central legislation such as the Environment Protection Act 1986 and policy frameworks issued by the Central Ground Water Authority. Fragmentation of jurisdiction has historically impeded coherent aquifer management. Excessive extraction through borewells, subsidised electricity for agricultural pumping and limited enforcement capacity have collectively depleted shallow and deep aquifers across large swathes of the country.
Telangana’s current approach reflects recognition of these structural failures. The state has reportedly undertaken approximately five hundred thousand rainwater harvesting initiatives and is pursuing rejuvenation of the Musi River alongside desilting of the Sriram Sagar reservoir to restore its storage capacity to 3,172 million cubic metres. The introduction of fines for wastage of potable water and proposals to supply treated grey water to data centres indicate a regulatory shift towards demand management and circular usage. Pandith Mandure, former director of the state groundwater department, observed that between 2021 and 2023 groundwater levels in the Hyderabad region rose by six to seven metres following lake clearance, recharge shafts and stepwell restoration. While correlation must be cautiously interpreted, such data suggests that decentralised recharge strategies can materially influence aquifer health.
From an international law perspective, India is a party to the International Covenant on Economic Social and Cultural Rights, which recognises the right to an adequate standard of living including access to water as elaborated by the United Nations Committee on Economic Social and Cultural Rights in General Comment No 15. Although implementation remains domestically mediated, chronic water scarcity may expose states to scrutiny regarding progressive realisation obligations. Moreover, climate variability intensifies the urgency. Erratic monsoon patterns attributed to climate change have increased reliance on groundwater buffers. Under the Paris Agreement, adaptation measures are as critical as mitigation commitments. Reviving stepwells constitutes a form of localised climate adaptation rooted in indigenous engineering knowledge.
The hydrological mechanics are straightforward yet powerful. Urbanisation has replaced permeable soil with concrete and asphalt, inhibiting natural infiltration. Stepwells were historically sited along natural gradients to capture runoff. Contemporary restoration projects must therefore incorporate engineered recharge systems including trenches and filtration layers of sand, gravel and stone to channel rainwater into aquifers. The Rainwater Project has integrated such methods, ensuring that surface runoff is diverted away from drains and towards recharge pits. This approach aligns with sustainable urban water management principles endorsed by global bodies such as UN Water and the World Bank.
The economic dimension cannot be ignored. India consumes approximately a quarter of the world’s groundwater, much of it for irrigation of water intensive crops. Declining aquifer levels increase energy consumption for pumping and exacerbate rural indebtedness. Urban tanker markets flourish in conditions of scarcity, often operating in regulatory grey zones. Kalpana Ramesh’s own reliance on rainwater harvesting for fifteen years underscores the feasibility of decentralised resilience, reducing dependence on commercial water tankers. Scaling such systems could alleviate fiscal pressure on municipal supply networks while enhancing community stewardship.
However, restoration of twenty five stepwells in Telangana, commendable though it is, cannot by itself reverse national water stress. Comprehensive reform requires integrated river basin management, rationalisation of agricultural subsidies that incentivise over extraction, strict enforcement of groundwater licensing and investment in wastewater treatment. It also demands behavioural change. As Ramesh emphasises, rainwater should not be allowed to disappear into drains. Public participation in maintaining ponds, lakes and streams adjacent to stepwell sites is indispensable. Without social legitimacy and vigilance, restored wells risk reverting to neglect.
The geopolitical implications are subtle yet significant. Water scarcity can exacerbate inter state tensions within federal systems and complicate transboundary river negotiations with neighbouring countries. India shares major river basins with Pakistan, Bangladesh, Nepal and China. Although stepwells address local aquifer recharge rather than river allocation, strengthening internal water security enhances negotiating stability and reduces vulnerability to climatic shocks.
The applause that greeted the return of water to Bansilalpet was therefore not sentimentalism. It was a recognition that centuries old infrastructure, once dismissed as obsolete, may offer partial answers to a modern crisis amplified by climate change, population growth and regulatory inertia. If potable filtration systems are installed across the restored wells, as proposed, public incentives to preserve them will strengthen further. The alternative is stark. Without systemic reform, projections indicate that demand could double by 2030 while aquifers continue to decline.
India’s water crisis is not a distant abstraction. It is measurable in metres of falling groundwater, in tanker queues, in farmer distress and in urban rationing schedules. The revival of stepwells demonstrates that resilience can be built from historical knowledge combined with contemporary engineering and legal reform. Yet the window for action is narrowing. The choice confronting policymakers is whether to treat these projects as symbolic heritage gestures or as catalysts for comprehensive water governance transformation. The difference between those paths may determine whether future applause celebrates revival or laments irreversible depletion.
