Executive Summary
In 2011, Kolkata Municipal Corporation (KMC) faced the challenge of modernizing its water management infrastructure to serve its growing population more effectively. This case study examines how Shanta Colibri India Private Limited (SCIPL) implemented and evolved the city's first comprehensive Water Information Management System, transforming water distribution for millions of residents over a decade of continuous innovation and expansion.
The Challenge
Initial Situation
Kolkata, one of India's largest metropolitan areas, faced several critical challenges in its water management system:
- Multiple water treatment plants with combined generation of 1800 Million Liters Daily
- Complex network of booster pumping stations and elevated service reservoirs
- Limited real-time monitoring capabilities
- Difficulty in tracking water distribution and losses
- Need for data-driven decision making for infrastructure investments
- Growing population demanding improved water services
Key Requirements
KMC needed a system that could:
- Monitor water generation from multiple sources
- Track distribution across the network
- Enable data-driven decision making
- Support future infrastructure planning
