IWM

Academic Chronology

Mr. Sagar Chandra Roy earned a Bachelor of Science in Civil Engineering from Bangladesh University of Engineering and Technology (BUET) in May 2022.

Professional Track Record

Since joining the Institute of Water Modelling (IWM) as a Junior Engineer in July 2023, Mr. Roy has contributed to sustainable urban water supply and sanitation systems through hydraulic modelling and GIS-based analysis. For the Update of the Water Supply Master Plan for Dhaka City, he assisted in future water demand forecasting, groundwater quality analysis using geostatistical methods, and an existing situation analysis of DWASA resources, while developing forward-looking strategies for IoT-enabled smart water metering, renewable energy integration, and equitable supply for Low-Income Communities (LICs). Simultaneously, he supported the Update of the Sewerage Master Plan by performing sewerage network modelling for the Purachal catchment and designing Fecal Sludge Management and non-sewer zone strategies aligned with Citywide Inclusive Sanitation (CWIS) principles. Beyond master planning, his practical expertise is evident in the Extended Dhaka Water Supply Resilience Project, where he utilized GIS tools to identify hard-to-reach areas, coordinated household surveys for demand analysis, and facilitated critical water supply connections.

• City Wide Inclusive Sanitation (CWIS) (April 2025, jointly organized by Seureca Veolia, IWM, and DevConsultants Limited).
• Sewage Treatment & Sustainable Sludge Management Technology (August 2025, jointly organized by Seureca Veolia, IWM, and DevConsultants Limited).

Mr. Roy has acted as a trainer for:

• Social & Household Survey and Existing House Connection Survey under Expanded Dhaka Water Supply Resilience Project (EDWSRP).

Major Project Assignments

Mr. Roy has contributed to several key projects at IWM, including:

• Co-ordinating household survey for water demand analysis and implementing water supply connection for Extended Dhaka Water Supply Resilience Project.
• Update of Sewerage Master Plan for Dhaka City – Non-sewer network zone identification and Fecal Sludge management strategies for non-sewer zone, coordinating slum sanitation survey, identifying hard to reach area for implementing sewer network by field survey and GIS tools, sewerage network modelling for the Purachal catchment, Citywide inclusive sanitation (CWIS) strategies integration for sanitation strategies improvement in Dhaka city.
• Update of Water Supply Master Plan for Dhaka City:
  • Assessment of Future Water Demand in Dhaka City – forecasting and scenario analysis for sustainable urban water management.
  • Groundwater Quality Analysis in Dhaka City – evaluation of iron, manganese, and other parameters using geostatistical methods.
  • Water Demand Management Tools and Strategies for Urban Areas – leak detection, pricing strategies, and conservation approaches.
  • Smart Water Metering strategies in DWASA – IoT-enabled monitoring for efficient water use and billing accuracy.
  • Use of Renewable Energy Sources in Water Supply Systems – integration of solar and wind energy into DWASA operations.
  • Water Supply in Low-Income Communities (LICs) – community-based studies addressing equity and resilience in service delivery.
  • Existing Situation Analysis of DWASA Resources – institutional and operational assessment for capacity strengthening.
