Areas of Capability
UNDP/WB funded SE Region Water Resources Development Programme inclusive of Gumti - Phase II and Noakhali North Drainage and Irrigation Project
This program entailed consolidation of two feasibility studies recently completed and addressing aspects of water resources development, inclusive of drainage and flooding issues. Proposals were formulated and a regional plan report submitted. In addition, upgraded proposals for the Dakatia / Litle Feni transfer scheme, including drainage of adjacent areas. The final report presented a water resource development plan to provide sustainable development of all parts of the regional economy, taking into account social and environmental factors. Areas where flooding impeded drainage and hampered economic activity, the project identified a series of measures to alleviate these adverse effects. It evaluated available water resources and proposed studies for cost effective development through-out the region.
Water Management Improvement Project, Bangladesh Water Development Board (BWDB)
The project involves enhancing institutional performance of Bangladesh Water Development Board (BWDB) and Water Resources Planning Organization (WARPO) and improving national water resources management by involving the local communities, to play an expanded role in all stages of the project cycle. The project consists of three key components, i.e. system improvement and management transfer-SIMT; O&M; performance improvement and institutional strengthening. The project is expected to result in reduced vulnerability and enhanced livelihood opportunities for the beneficiaries, and create a favourable environment for improved water management by the core water institutions in partnership with beneficiaries.
Review of Options for the Development of Ground and Surface Water Irrigation Project ADB TA to the Bangladesh Water Development Board (BWDB)
RDC was the lead firm on this technical assistance to the BWDB, the agency responsible for the development of irrigation, flood control and drainage schemes in Bangladesh. The BWDB handled 4 major surface water schemes. The main objective of the study was to review the existing schemes to identify areas within them and other minor schemes which are not adequately supplied with water for irrigation during the dry season. The consultants reviewed the coverage of existing irrigation schemes, compiled data, assessed prevailing mechanisms, legal and organisational procedures by which BWDB operates, to ascertain the economic viability of these schemes. The review further examined the reasons why farmers installed irrigation wells privately in the BWDB scheme areas, assessed the acreage that can be opened up to added minor irrigation facilities, evaluated the impact of such measures; the configuration of existing surface water and ground water regimes, and examined the technical implications of removing site restrictions. In conclusion, the review made recommendations towards the conjunctive development of both private groundwater schemes and public surface water systems run by the BWDB.
