Credit No.: IDA-64450

Assignment Title: Consultancy service for Feasibility Study and Detail Design, Tender Document preparation, evaluation and Construction Supervision for Well Drilling of Climate Resilient Water Supply, Sanitation and Hygiene Facilities for Salahad and Dhuhun Woredas Multi-Village Water Supply project in Somali Region.

Reference No.: ET-WDC-202184-CS-QCBS

The Federal Democratic Republic of Ethiopia (FDRE) has received financing from the World Bank toward the cost of implementation of Water Supply, Sanitation and Hygiene Project and intends to apply part of the proceeds for consulting service.



The overall objective of the assignment is to carry out alternative source assessment with specific attention to groundwater source for the community and institutions (schools and health institutions) and status of existing Water Supply, Sanitation and Hygiene in Salahad woreda (Salahad Multi village Water Supply project) and in Duhun Woreda (Duhun Multi village Water Supply project) of Somali region. Identify the kebeles seriously affected in consultation with the respective communities, woreda and region sector offices and Bureaus (Water, Health and Education). Based on the findings of the assessment report, under take community and institutions water supply, sanitation and hygiene service facilities feasibility study for the selected kebeles/ villages/gots, institutions (health institutions, schools e.t.c.), and manage the selection of qualified groundwater drilling company and supervision of works of (if applicable) and prepare detail design based on the outcome of the feasibility study.
