Making Water Infrastructure a National Priority for Climate-Resilient India
As India pursues sustainable growth, water infrastructure must become a central pillar of national policy
Mr. Arun Lakhani, Chairman and Managing Director, Vishvaraj Environment Ltd.
As India charts its path toward sustainable and climate-resilient growth, water infrastructure must move from being a sectoral concern to becoming a core national policy priority. Rapid urbanisation, industrial expansion, and climate variability are intensifying pressure on freshwater resources, making it imperative to reimagine how water is sourced, treated, distributed, and reused. The Union Budget can play a catalytic role in this transition by positioning water infrastructure—particularly treated wastewater reuse, irrigation modernisation, and PPP–HAM–based water delivery systems—as a strategic pillar of India’s growth agenda.
One of the most critical interventions required is the establishment of a national-level policy and programme for treated wastewater reuse. Mandatory reuse targets for cities, industries, and utility clusters would significantly reduce dependence on freshwater sources and help address mounting water stress. When treated wastewater is systematically integrated into industrial processes, cooling applications, and urban non-potable uses, it not only conserves freshwater but also creates a circular water economy that improves overall system efficiency. To make this viable at scale, assured offtake frameworks must be created, enabling utilities and industrial clusters to commit to long-term procurement of treated water and thereby strengthen the financial sustainability of reuse projects.
Equally important is the creation of a structured policy framework that enables institutional reforms and encourages private sector and capital market participation. PPP–HAM–based models have demonstrated their effectiveness in infrastructure development, and extending these models to treated wastewater reuse and irrigation modernisation can unlock large-scale investment. Clear risk-sharing mechanisms, standardised concession frameworks, and long-term policy certainty will help attract developers, operators, and long-term investors. In parallel, establishing independent state-level water regulators with uniform tariff-setting principles and cost-recovery models will introduce transparency, predictability, and financial discipline across the sector.
Budgetary support remains a vital enabler of this transformation. Enhanced allocations to key sewerage and water infrastructure schemes will be necessary to drive large-scale implementation, particularly in urban centres where compliance with National Green Tribunal (NGT) norms remains a challenge. Targeted funding can accelerate the creation of sewage treatment capacity, strengthen conveyance networks, and support last-mile connectivity for reuse applications.
Capital market instruments should also be actively leveraged to deepen funding avenues. Introducing incentives for green bond issuance by Urban Local Bodies can provide access to long-term, low-cost capital while aligning urban infrastructure financing with sustainability objectives. Green bonds, combined with budgetary support and PPP frameworks, can create a blended finance ecosystem capable of supporting India’s ambitious water infrastructure goals.
Taken together, long-term policy clarity, institutional reforms, and capital market enablement can elevate water infrastructure to the same strategic importance as energy, transport, and digital infrastructure. By embedding treated wastewater reuse, irrigation modernisation, and sustainable water delivery systems into national policy and budgetary priorities, India can build a resilient water future—one that supports economic growth, protects ecosystems, and ensures water security for generations to come.
