Expert Perspective: According to Dr. Sunderrajan Krishnan, Executive Director of the India Natural Resource Economics and Management Foundation, “Citizen-generated data, when validated and combined with IoT streams, creates a powerful feedback loop for both communities and policymakers.”

Policy Engagement and Crowdsourced Innovation

Digital platforms are democratizing policy participation and innovation in water safety. The MyGov portal, launched by the Government of India, regularly hosts public consultations, hackathons, and innovation challenges focused on water management and digital solutions. These forums enable citizens, technologists, and policymakers to co-create actionable strategies and accelerate the adoption of IoT technologies.

Real-World Example: In 2023, the “Jal Shakti Hackathon” on MyGov attracted over 10,000 participants, resulting in the development of a mobile app that integrates IoT sensor data with citizen-reported water quality issues, now being piloted in Maharashtra.

By leveraging these diverse participation opportunities, India is building a collaborative ecosystem where technology, policy, and community action converge to ensure safe, reliable water for all. The integration of IoT in water safety is not just a technological leap—it is a collective movement, powered by informed, engaged, and empowered citizens.
