India’s Water Crisis Won’t Wait And Circularity Is Key To Securing Our Water Future

Water is the foundation of life and progress, and India has long relied on its vast network of rivers, lakes, and groundwater reserves. However, with increasing demand and changing climate patterns, the country faces a pressing need for a more resilient approach to water management. Successful rainwater harvesting models, advancements in wastewater treatment, and government-led projects like the Jal Jeevan Mission demonstrate that viable solutions exist.

Yet, challenges persist—Chennai nearly ran out of water in 2019, and in Punjab, groundwater levels are declining at an alarming rate of 25-30 cm per year. To secure a sustainable future, India must now transition toward a system that not only conserves but also reuses and recycles water efficiently.

With industrial water demand projected to double by 2030 and agriculture already consuming nearly 80% of the country’s freshwater, conservation alone is insufficient. To secure a sustainable future, India must transition toward a circular water economy—a system where water is treated, reused, and efficiently distributed.

Agriculture, the largest consumer of freshwater in India, presents a significant opportunity for reform. Traditional irrigation methods like flood irrigation lead to excessive consumption and groundwater depletion. Studies suggest that adopting drip irrigation can cut water usage by up to 50% while boosting crop yields by 30-40%. Countries like Israel, which recycles nearly 90% of its wastewater and has successfully implemented large-scale drip irrigation, offer valuable lessons. Encouragingly, Indian cities like Indore and Surat have begun implementing decentralized wastewater treatment systems, proving that scalable solutions are within reach. By embracing technology-driven water management practices, India can build a resilient and water-secure future.

Building A Water-secure India
For India to achieve long-term water security, the shift to a circular water economy must be more than just an idea—it needs to be an integrated approach across industries such as agriculture or urban planning, to name a few. While challenges like groundwater depletion and erratic rainfall persist, scalable solutions already exist. Cities and industries that have embraced wastewater recycling, efficient irrigation, and decentralized treatment systems are proving that water sustainability is not only possible but also economically viable.

One of the most pressing areas for change is how India manages wastewater. Currently, only 28% of wastewater is treated, with the rest polluting rivers and groundwater.

From Disposal To Circular Utilisation
Cities like Surat, however, have demonstrated the benefits of circular water management. Surat’s textile industry has significantly reduced its freshwater dependency by reusing 60 million liters of treated wastewater daily. Scaling such initiatives across industries can create a water-resilient economy. Governments must collaborate with private enterprises to set up decentralized wastewater treatment plants, provide subsidies for adoption, and enforce water recycling regulations.

Industrial Water Stewardship
Zero Liquid Discharge (ZLD) regulations, which mandate that industries treat and reuse all their wastewater without discharging any liquid waste into the environment, exist but face enforcement challenges. Despite this, many companies have adopted water-positive business models, returning more water to the ecosystem than they consume. However, a truly circular water economy extends beyond wastewater reuse—it also involves replenishing natural water reserves. Industries must integrate rainwater harvesting (RWH) systems to reduce groundwater depletion while optimizing water recycling. By investing in AI-driven water monitoring, closed-loop water systems, and industry-wide water-sharing models, businesses can minimize freshwater extraction and actively contribute to environmental restoration.

Encouraging Policy-driven Business Action
With India housing 17.78% of the world’s population but having access to just 4% of global freshwater, optimizing water use is no longer optional — it’s essential. Policies for water conservation exist, but incentivizing industries to adopt water-efficient practices can significantly accelerate change.

Advanced water recycling technologies, like Singapore’s ‘NEWater’ initiative, which treats and repurposes wastewater for industrial use, present a viable model for India. Implementing such initiatives at scale can reduce the strain on freshwater sources, ensuring that limited reserves are utilized more efficiently.

Governments must play a key role by providing tax benefits for companies investing in sustainable water management solutions.

Investing In Ecosystem Recovery
Restoring India’s traditional water bodies is as important as technological solutions. In Bengaluru, over 90% of lakes have been lost to urbanization. However, initiatives like the rejuvenation of Jakkur Lake—where treated wastewater is used to replenish the lake and support local biodiversity—demonstrate the impact of public-private partnerships. Treating and reusing wastewater not only reduces freshwater dependency but also minimizes environmental damage caused by the discharge of untreated sewage into rivers and groundwater. By curbing pollution and maintaining ecological balance, circular water practices can help restore natural ecosystems. Businesses must co-invest in such large-scale water restoration projects alongside government and non-profits to create long-term resilience.

Securing India’s water future is not just a matter of policy — it’s a collective responsibility that demands decisive action. Businesses must lead by example, integrating closed-loop water systems and supporting large-scale water restoration projects. Policymakers need to strengthen incentives for water reuse, enforce stricter compliance with Zero Liquid Discharge norms, and promote circular water models across sectors. Communities must actively participate in water stewardship, holding industries and governments accountable.

The choices we make today will determine India's water future. By committing to a circular water economy, India can not only safeguard its water resources but also set a global benchmark in sustainable water management. Collaborative efforts today will define whether future generations inherit a water-secure nation or face an unavoidable crisis.
