Blitz Bureau
NEW DELHI: What happens when you combine the ‘India Stack’ with a water pump? You get Sujalam Bharat – the digital backbone of JJM 2.0.
Launched in early 2026, this framework is being hailed as the ‘Fitbit for India’s Hydrology’. Every village is now mapped on a National Digital Platform. Here is what the tech looks like on the ground:
Smart meters for slums: In experimental ‘Model Solar Villages’, households are fitted with ultrasonic smart meters that track usage. If a leak is detected (indicated by a constant flow at 3 AM), an SMS is sent to the local technician.
Transparency ledger: Every ‘Har Ghar Jal’ certification is now tied to a blockchain-backed ledger. A Gram Panchayat can only claim the ‘Achiever’ status after 12 months of verified, uninterrupted data showing water reached the tail-end of the pipeline.
Greywater AI: In states like Haryana, AI is being used to design ‘greywater management’ systems, calculating exactly how much laundry and kitchen water can be diverted to local ponds for irrigation without causing soil salinity.
While the ‘Internet of Water’ sounds futuristic, it addresses a very old problem: leakage. Estimates suggest that 40 per cent of India’s piped water was lost to leaks or theft before 2024. In 2026, the Sujalam Bharat framework aims to bring that down to 10 per cent, ensuring that every drop pumped is a drop used.
