Why India’s new economic metrics recognise the value of sanitation, waste management and environmental services

Recent revisions in India’s economic and industrial statistics may appear technical in nature, attracting the attention of economists, statisticians and policy specialists. Yet embedded within these reforms is a development that deserves far wider public discussion: the explicit recognition of water supply, sewerage, waste management and related environmental utility services within the country’s evolving framework for measuring economic activity.

At one level, this is a statistical refinement. At another, it reflects a profound shift in how India understands economic value, productivity and development itself.

For decades, economic growth has largely been associated with sectors such as manufacturing, mining, construction, trade and energy production. These sectors remain indispensable to national prosperity. However, the economy of the twenty-first century is increasingly influenced by factors that were once considered peripheral to mainstream growth discourse – environmental sustainability, urban resilience, public health infrastructure, resource efficiency and circular economy systems.

India’s recent statistical reforms implicitly acknowledge this changing reality.

The inclusion of water supply, sewerage and waste management services within the revised industrial classification framework recognises that these sectors generate substantial economic value. Activities such as waste collection, segregation, recycling, wastewater treatment, resource recovery and waste-to-energy generation are no longer merely municipal services. They create employment, attract investment, stimulate technological innovation and contribute directly to economic productivity.

Historically, however, much of this contribution has remained inadequately reflected in conventional measures of economic performance.

This matters because economic statistics do far more than record activity. They influence how governments allocate resources, how investors assess opportunities and how policymakers establish priorities. What is measured becomes visible. What becomes visible attracts institutional attention, financial capital and policy support. Conversely, sectors that remain statistically underrepresented often struggle to secure the recognition and investment they warrant.

By bringing environmental utility services into mainstream economic measurement, India is elevating them from the margins of development policy to a position of greater economic significance.

The timing is particularly important.

India is urbanising at an unprecedented scale. Growing populations, rising consumption patterns and expanding urban settlements are placing immense pressure on sanitation systems, wastewater treatment infrastructure and solid waste management services. In response, municipal bodies and state governments are investing heavily in sewage treatment plants, integrated waste management facilities, recycling systems and waste-to-energy projects.

These investments should not be viewed merely as environmental expenditures. They are productive economic assets. They contribute to healthier populations, reduce disease burdens, improve labour productivity, enhance urban liveability and support sustainable economic growth.

Accurately measuring their contribution, therefore, leads to a more accurate understanding of the economy itself.

The broader statistical reforms underway reinforce this transition. Improved GDP estimation methodologies, greater use of administrative databases, enhanced industrial classifications and updated inflation measures all seek to ensure that economic statistics reflect contemporary economic realities rather than outdated structures.

Yet the recognition of waste management and sewerage services points towards an even larger transformation in developmental thinking.

Historically, development was often associated with the extraction of resources and the production of goods. Increasingly, however, prosperity depends not only on production but also on how effectively societies manage resources after they are consumed. In an era characterised by climate change, water stress, environmental degradation and rapid urbanisation, the capacity to recycle, recover, conserve, treat and regenerate resources is becoming a strategic economic capability in its own right.

This is the defining logic of the emerging circular economy.

Viewed through this lens, the inclusion of sanitation, waste management and environmental services within economic statistics is not simply a technical adjustment. It broadens the definition of productive activity and challenges long-standing assumptions about what constitutes economic value.

India’s statistical reforms, therefore, represent more than a modernisation exercise. They signal a gradual but important evolution in development thinking—one that recognises that future prosperity will depend not only on what the country produces, but also on how effectively it manages its resources, protects public health, strengthens environmental sustainability and sustains the functioning of its cities.

The revision of GDP methodologies may attract economists. Changes in inflation indicators may interest financial markets. Yet the recognition accorded to sanitation, sewerage and waste management may ultimately prove equally consequential. It reflects a growing understanding that the foundations of economic growth extend well beyond factories and markets to include the systems that sustain human wellbeing, environmental integrity and urban resilience.

Sometimes, the most significant shifts in public policy are not found in headline announcements. They emerge quietly through the way a nation chooses to measure its progress.
