India’s water challenge is no longer simply about whether households have access to a tap, farmers can irrigate their fields, or cities can supply water to growing populations. It is about whether the country can secure enough water, of adequate quality, at an affordable cost, without depleting the natural systems on which future supplies depend.

The distinction matters. Water is simultaneously a basic human necessity, an agricultural input, an industrial resource, an urban service and an essential foundation of public health. Shortages and pollution therefore carry costs that extend well beyond the water sector. They affect household budgets, productivity, food security, the environment and the pace of economic development.

The scale of the challenge is considerable. India accounts for about 18% of the world’s population but only around 4% of its freshwater resources. Rainfall is highly seasonal and geographically uneven. Groundwater is under pressure in several regions, urban demand is rising, and pollution reduces the quantity of water that can safely be used. The World Bank and other development institutions have repeatedly highlighted the implications of these pressures for India’s long-term economic and climate resilience.

Access Is Progress, but Reliable Service Is the Test

The Jal Jeevan Mission, launched in August 2019, has substantially expanded the ambition of rural drinking-water provision. At its launch, approximately 3.24 crore rural households—about 16.72% of the total—were reported to have tap-water connections.

According to the Ministry of Jal Shakti, 15.89 crore rural households, or 82.09% of the approximately 19.36 crore rural households in the country, had been provided tap-water connections by July 18, 2026. This represents considerable progress in extending household infrastructure.

The next stage is equally important. In March 2026, the Union Cabinet approved the restructuring of the Jal Jeevan Mission as Jal Jeevan Mission 2.0, extending its period to December 2028 and enhancing its total outlay to ₹8.69 lakh crore, including central assistance of ₹3.59 lakh crore. The reorientation places greater emphasis on service delivery, drinking-water governance and institutional arrangements for sustainable rural piped-water supply. The proposed Sujalam Bharat digital framework is intended to map drinking-water systems from source to tap.

This change in emphasis is welcome. A household connection does not, by itself, establish whether water flows regularly, is safe to drink, or remains affordable. The remaining coverage gap matters, but so does the quality of service received by households already counted as connected.

A water-secure system must therefore measure more than infrastructure installed. It must examine continuity of supply, water quality, functionality of connections, local maintenance and the ability of communities to manage their water sources over time. The responsibility for planning, implementation, operation and maintenance also requires effective coordination between the Centre, state governments and local institutions.

The Hidden Health Cost of Polluted Water

Water security must also be understood as a public-health priority. Unsafe drinking water and inadequate sanitation expose people to preventable diseases, including diarrhoeal infections, cholera, dysentery, hepatitis A and typhoid. Chemical contamination creates additional risks. Arsenic, fluoride and nitrate, for example, can affect health even when water looks clear.

The World Health Organization has repeatedly emphasized the connection between safe water, sanitation and health. The consequences are not confined to the cost of treating illness. Families may have to pay for medicines, medical consultations, filtration or alternative drinking-water supplies. Children can miss school, adults can lose working days, and repeated illness can undermine nutrition and household financial security.

These burdens fall particularly heavily on low-income families, who have less capacity to buy safe water or absorb medical expenses. India must therefore treat water quality as a development indicator in its own right. A tap connection that delivers contaminated or unreliable water cannot be regarded as the full achievement of water security.

The Ministry of Jal Shakti has identified drinking-water quality as an important part of the Jal Jeevan Mission and uses the Bureau of Indian Standards’ IS 10500 standards as the benchmark for drinking-water quality. Its August 2026 statement also highlighted groundwater-quality monitoring and remedial measures for localized contamination, including arsenic and fluoride. These efforts need to be matched by effective testing, timely disclosure, appropriate treatment and dependable supplies of safe water.

The policy test is not merely whether a water source exists, but whether the water is safe at the point of consumption.

Groundwater: A Resource That Cannot Be Taken for Granted

Groundwater is central to India’s drinking-water supply, agriculture and industry. The Central Ground Water Board’s Dynamic Ground Water Resources Assessment 2025, released by the Ministry of Jal Shakti, estimated annual groundwater recharge at 448.52 billion cubic metres and annual extractable groundwater resources at 407.75 billion cubic metres. Annual extraction was estimated at 247.22 billion cubic metres, equivalent to an extraction stage of 60.63%.

The national average, however, conceals substantial local variation. The assessment classified 730 of 6,762 groundwater assessment units—10.8%—as over-exploited. Some regions face far greater pressure than the national figure suggests, while chemical contamination poses a separate challenge in certain areas.

The August 2026 information provided by the Ministry of Jal Shakti indicates that approximately 87% of groundwater extraction is used for irrigation, 11% for domestic purposes, including drinking water, and 2% for industrial purposes. This distribution highlights why groundwater policy cannot be separated from agricultural and energy policy.

The rise in the share of assessment units classified as safe, reported in the 2025 assessment, is encouraging. Yet it should not weaken the case for conservation. Groundwater depletion can increase pumping costs, deepen dependence on electricity, reduce resilience during droughts and make water less accessible to smaller farmers and poorer households.

India needs aquifer-level planning, better monitoring, rainwater harvesting, protection of wetlands and ponds, and stronger incentives to use groundwater efficiently. Easier access to deeper bore wells should not become a substitute for managing demand and replenishing aquifers.

Agriculture Must Become More Water-Efficient

Agriculture is both a major source of livelihood and a major user of water. Improving irrigation efficiency is therefore central to water security. Micro-irrigation, better scheduling, soil-moisture management, suitable crop choices and locally adapted agricultural practices can reduce unnecessary water use.

The Pradhan Mantri Krishi Sinchayee Yojana, including its Per Drop More Crop component, supports improved irrigation access and on-farm water-use efficiency. The Ministry of Jal Shakti also supports the restoration of water bodies and minor irrigation infrastructure through relevant components of the programme.

Crop planning should reflect rainfall, soil conditions, aquifer stress and the water available in each region. Water-intensive crops may be viable in some locations but unsuitable in areas where rainfall is unreliable and groundwater is under severe pressure. Farmers will need access to information, extension services, appropriate technology, markets and economic incentives to make such transitions practical.

Rainwater harvesting and the restoration of ponds, tanks and traditional water bodies can help retain rainfall that would otherwise run off rapidly. The Ministry’s Mission Amrit Sarovar has supported the development and rejuvenation of nearly 69,000 water bodies, while the Jal Shakti Abhiyan: Catch the Rain and Jal Sanchay Jan Bhagidari initiatives promote rainwater harvesting, recharge and community participation.

The Ministry’s August 2026 update also reported that Jal Sanchay Jan Bhagidari–Catch the Rain 2026 was launched on June 1, 2026. Its emphasis on local participation and low-cost rainwater-harvesting structures is relevant to India’s need to conserve water where it falls. The lasting value of these initiatives, however, depends on maintenance, protection from encroachment and pollution, and integration with local watershed plans.

Cities Need to Treat Wastewater as a Resource

Urban growth places increasing pressure on water supply, drainage and sanitation. Cities cannot sustainably address this pressure by continually searching for new sources while allowing usable water to leak from networks or wastewater to pollute rivers and lakes.

Leak detection, metering, efficient fixtures, rainwater harvesting, protection of urban lakes and the reuse of treated wastewater should become standard elements of urban water planning. Properly treated wastewater can support industrial processes, landscaping, construction and other suitable non-drinking uses, reducing demand for freshwater.

The Council on Energy, Environment and Water and the Asian Infrastructure Investment Bank’s September 2026 publication, India Water Digest: Scaling Investment for a Water-Secure India, emphasizes the importance of investment, institutional capacity, micro-irrigation, treatment and reuse of used water, and smarter water infrastructure. The central challenge is not only to build treatment plants and networks, but also to ensure that they operate effectively and that treated water is safely reused.

A sewage-treatment plant that does not operate properly cannot deliver its expected environmental benefits. A distribution network that loses substantial quantities of water undermines the value of additional supply. Investment appraisal should therefore consider not just construction costs, but also operating performance, maintenance and the long-term value of the water saved or recovered.

Investment Must Deliver Measurable Results

India’s water-security agenda draws on public programmes and multilateral partnerships. The World Bank has supported initiatives intended to strengthen water security, including the Karnataka Water Security and Resilience Program approved in June 2025. In Bengaluru, a World Bank-supported project includes lake restoration, sewage-treatment improvements, treated-wastewater reuse and expanded sewerage connections.

The Asian Development Bank’s Asian Water Development Outlook 2025 provides a wider regional framework for water security. In August 2026, the ADB signed a $230 million loan for a Chennai water and sewerage project intended to improve services for approximately 4.5 million people. The project includes network modernization and measures to strengthen water and sewerage services across a substantial part of the city.

The New Development Bank has supported water-related projects in India, including integrated sewerage infrastructure in Imphal and the $70.27 million Lamphelpat Waterbody Rejuvenation Project in Manipur. These interventions address different but related dimensions of water management: wastewater collection and treatment, urban environmental improvement and water-body restoration.

These initiatives illustrate the range of interventions required, from urban water networks and sewerage to groundwater management and restoration of natural infrastructure. Their success should be judged by outcomes: more reliable supply, lower leakage, cleaner water bodies, improved water quality, reduced exposure to pollution and greater reuse of treated wastewater.

Investment is necessary, but it is not sufficient. Effective project design, capable institutions, reliable operating budgets, maintenance and transparent performance monitoring determine whether infrastructure produces lasting benefits.

International Cooperation Can Strengthen Water Security

India’s water challenge also has an international dimension. Rivers cross national boundaries, floods affect downstream communities, and climate-related hazards can create risks that no single jurisdiction can manage entirely on its own.

India’s engagement with Bhutan provides an example of practical cooperation. Discussions in August 2026 covered transboundary river management, hydrological data, flood forecasting, hydrometeorological networks and related climate risks. Cooperation on early warning, including risks associated with glacial lake outburst floods, can strengthen preparedness and improve the sharing of information needed for timely decisions.

There are also opportunities for practical exchange through ASEAN and BRICS. Countries face different combinations of urban flooding, water shortages, pollution, wastewater-management challenges and agricultural demand. Cooperation can help identify workable approaches to monitoring, treatment, reuse, water-efficient agriculture and resilient infrastructure.

India–Africa cooperation offers another avenue. A water, sanitation and hygiene roundtable held on September 24, 2026, involving 22 African countries, provided a basis for discussing areas of shared interest. Potential cooperation could include community-level water management and monitoring in Kenya, watershed restoration and rainwater harvesting in Ethiopia, and wastewater reuse and urban water-loss reduction in South Africa. These are potential areas for collaboration, not evidence of agreements already concluded.

International partnerships should be judged by their measurable contribution to water security rather than by the number of meetings or agreements. Technical knowledge, financing and monitoring are means to improve outcomes on the ground.

From Water Infrastructure to Water Security

India’s water challenge calls for a shift from counting projects to measuring results. The priorities are clear: ensure safe and reliable drinking water; protect groundwater; restore local water bodies; improve irrigation efficiency; reduce pollution; treat and reuse wastewater; and fund the maintenance of infrastructure after construction.

The reorientation of Jal Jeevan Mission under JJM 2.0 creates an opportunity to make service reliability, source sustainability and institutional accountability central to rural water policy. The same results-oriented approach should guide urban water investments, groundwater management, agricultural programmes and international cooperation.

Progress should be visible in fewer interruptions to household supply, safer drinking water, lower exposure to contamination, reduced pressure on aquifers, more productive irrigation and cleaner urban water bodies. It should also be reflected in reduced household expenditure on avoidable illness and alternative water supplies, fewer lost school and work days, and stronger resilience among vulnerable communities.

These outcomes require coordination across water supply, sanitation, agriculture, public health, urban planning, environmental regulation and local government. They also require transparent measurement of what works and the willingness to maintain or redesign programmes when results fall short.

The fundamental point is that water security is not achieved when a project is inaugurated or a household is counted as connected. It is achieved when people can depend on safe water, farmers can use it efficiently, cities can manage wastewater responsibly, and ecosystems can continue to replenish the resources on which the economy depends.

Jal Shakti must ultimately mean more than water infrastructure. It must mean better health, stronger livelihoods, greater resilience and a water-secure future for India.
