Services of Water Supply, Sanitation and Urban Water Management (WSU)

The main services of this Division are:

1. Integrated Water Resources Management (IWRM)

IWM has achieved a leading position within the field of integrated management of land and water resources, and provides comprehensive expertise together with a range of decision support tools to understand and simulate a variety of hydrological aspects ranging from broad-scale river basin issues to detailed hydrological and hydrodynamic investigations.  Projects often require integration of various aspects, such as conjunctive use of ground water and surface water, water quantity and quality, water uses, industrial water management and integration of the natural systems into human (political and institutional) systems. In the recent years IWM has contributed to development of scenarios, visions and actions within the so-called Vision and Framework for Action process through participation in Global Water Partnership and regional collaborations. This approach consists of a comprehensive set of analysis steps, supported by mathematical tools for the analysis of natural resource systems in a socio-economic context. Using this approach IWM supports water, river and floodplain managers worldwide in structuring complex decision-making processes and provide technical know-how for effective evaluation of planning alternatives. Information management systems, decision support systems and simulation models are important tools in this respect. Services would include:

  • Water resources assessment and management
  • Master planning and policy development
  • Water supply and demand assessment
  • River Basin management
  • Environmental impact analysis

3. Water Network Review in the Rohingya Refugee Camps, Cox's Bazar (Client: UNICEF)

This project focuses on reviewing the 298 nos. water networks across 33 Rohingya camps in Ukhiya and Teknaf, assessing its functionality, water quality, and identifying current challenges and successes. Key tasks include reviewing existing water supply scheme documents, preparing data collection tools, and training enumerators. The assessment will measure various aspects such as pump volume, energy supply, tank volume, and water quality parameters like chlorine levels. The collected data will be analyzed and presented through fact sheets, graphs, tables, and maps, followed by a validation workshop and the preparation of a final report with recommendations. The project aims to ensure that the water network meets the needs of the refugee population effectively, providing insights into necessary improvements. Ultimately, the findings will guide future priorities and actions for the remainder of the year, ensuring the sustainability and efficiency of the water supply system.

5. Feasibility Study of Integrated Water Resources Management of Chalan Beel Area

Understanding of the level of water quality parameters is essential for the conservation of environment including drinking, irrigation, fisheries and recreation. During recent days IWM has acquired sufficient skill in monitoring the following water quality parameter for different studies.

  • Salinity

  • Biochemical Oxygen Demand (BOD)

  • Chemical Oxygen Demand (COD)

  • Dissolved Oxygen (DO)

  • Ammonia (NH3), Nitrate (NO3)

  • Lead (Pb), Chromium (Cr)

  • Mercury (Hg)

  • Phosphate (PO4)

  • Coliforms

  • Turbidity

11. Planning and Design of Community Piped Water Supply Systems for Rohingya Camps and Host Communities (Client: UNICEF)

This project focused on planning and designing water supply systems for Rohingya and host communities, with an emphasis on inclusive community consultations and in view of increase social cohesion. The process involved active engagement with local authorities and communities, ensuring the participation of women, girls, and individuals with disabilities during site visits and facility design. Key tasks included conducting topographic surveys, soil tests, and environmental screenings at 10 locations, as well as performing exploratory drilling and monitoring well construction at 6 sites. Hydraulic designs were developed for each water supply system, incorporating solar pumping solutions and detailed structural designs for 10 systems. Comprehensive bid documents were prepared, including Bill of Quantities (BoQ), cost estimates, and technical specifications for all sites. Close collaboration with UNICEF Implementation Partners (IPs) was maintained throughout the fieldwork and design phases to ensure adherence to global best practices. The project culminated in the preparation and presentation of a final report, which included all design documents and recommendations for the sustainable implementation of the water supply systems.
