Ensuring reliable and continuous water supply is a critical step toward building water-resilient cities in India. In this second session of the Making India Water Resilient series, Dr. Sanjay Dahasahasra explores the transition from intermittent to 24×7 pressurised water supply systems and the key challenges that have historically limited their implementation across the country.
This webinar dives into the practical role of GIS and hydraulic modelling in planning, designing, and managing modern water distribution networks. Attendees will gain insights into GIS-based workflows—from base map creation, georeferencing, and digitization to developing hydraulic models with accurate elevation and demand data. The session also highlights the use of Autodesk InfoWorks WS Pro for advanced network modelling and demonstrates how District Metered Areas (DMAs) can improve operational control and reduce non-revenue water (NRW).
A detailed case study of the Lormi 24×7 Water Supply Scheme will showcase real-world applications, key outcomes, and lessons learned. The session concludes with actionable insights for engineers, planners, and decision-makers working toward sustainable and efficient urban water systems.
Join us to discover how digital technologies can enable smarter water infrastructure and support India’s journey toward water resilience.
