India's Jal Jeevan Mission Success Masks Emerging Water Reliability Crisis

New analysis of National Family Health Survey-5 district-level data reveals a paradox at the heart of India's water policy: districts with greater piped-water coverage are more likely to report water supply disruptions, pointing to an emerging challenge of reliability poverty distinct from traditional access poverty. The Jal Jeevan Mission has connected millions to piped water, but connection does not guarantee that water flows when households need it.

The NFHS-5 analysis, which asked households whether their primary drinking water source had been unavailable for at least one full day during the two preceding weeks, found significant geographical clustering of disruption hotspots across western India, Rajasthan, parts of the Western Ghats, selected Himalayan districts, and the Northeast. The Global Moran's I value for water disruption was 0.614 (p<0.001), confirming strong spatial clustering. Bivariate spatial analysis found significant overlap between high piped-water coverage and frequent water interruptions.

Households connected to centralised piped networks depend on reservoirs, treatment plants, pumping stations, electricity, and distribution systems — each a potential single point of failure affecting thousands of households simultaneously. Karnataka's 2024 water crisis, in which Bengaluru faced rationing and expensive tanker dependence despite extensive network coverage, illustrates how infrastructure can co-exist with water insecurity. In Aizawl, one of India's wettest regions, power failures and pipeline repairs disrupted supply to thousands of households in 2025, demonstrating that abundance of water does not guarantee reliability of access.

The analysis distinguishes between access poverty — the absence of water infrastructure — and reliability poverty, where infrastructure exists but dependable service does not. As centralised water systems expand and climate variability intensifies pressure on reservoirs and groundwater, reliability poverty may emerge as a more critical challenge than continued infrastructure extension. The authors call for monitoring frameworks to move beyond counting connections and incorporate continuity, functionality, and source sustainability metrics alongside investment in climate adaptation and watershed restoration.
