India's cities face mounting water challenges — from overburdened supply networks and inadequate sanitation to rising flood risk and fragmented governance. Addressing these demands more than isolated fixes; it requires a holistic, coordinated approach that sees the urban water cycle as a whole.

Integrated Urban Water Management (IUWM) offers exactly that. By treating water supply, sanitation, and stormwater as interconnected systems rather than separate silos, IUWM provides a framework for smarter, more resilient urban water planning. Yet one of the most persistent barriers to its adoption in India has been the absence of a robust, unified data foundation to guide decision-making.

CWIN — the City Water Information Network — was built to change that.

Developed for Gwalior, CWIN is a dynamic, data-driven dashboard that brings together the city's entire urban water ecosystem in one place: water resources, supply networks, wastewater, stormwater systems, the city's Master Plan, and spatial data. It offers real-time visualisation of water-related information, identifies flood-prone zones and groundwater recharge hotspots, maps optimal areas for treated wastewater reuse, and flags communities most vulnerable to flooding. It also highlights opportunities for afforestation and helps municipal officers and planners move from weeks of manual analysis to instant, actionable insight.

More than a tool for Gwalior, CWIN is envisioned as a replicable model — a proof of concept that other Indian cities can adapt as they navigate their own water futures.
