Overview

Government of Ethiopia’s Climate Resilient WASH strategy plans for Development of Sustainable Water Supply, Sanitation and Hygiene Program in Drought Prone Areas of Ethiopia, UNICEF Ethiopia through the Urban WASH programme is supporting government programs in Oromia and SNNP Regions to drill deep boreholes and develop new large water supply schemes for Climate-Resilient and Sustainable Water Supplies. UNICEF planned to implement Water Supply with the financing from KfW.

UNICEF-Ethiopia selected Blue Matrix Consultancy for Consultancy Service for Feasibility Studies, Detail Design and Supervision Works of three (3) Towns and up to 15 Satellite Villages Water Supply and Sanitation Schemes. 

  • Bidre Town and adjoining satellite villages 
  • Doyo Gena town and adjoining satellite villages 
  • Bulle Town and adjoining satellite villages

The beneficiaries of the project is about 213,146 in 2032: initial year of service is projected to reach 213,146 in 2032. The project aims to improve the health and well-being of communities in the town & selected Surrounding Satellite Villages, in equitable manner by increasing access to water supply and sanitation and adaptation of good hygiene practices.

 

The provision of water supply demands provision of adequate and sustainable water source; accordingly, following population projection and demand estimation; source investigation for all three towns and over 15 satellite villages had located and identified feasible water source and proposed well field to develop about twenty [20] deep wells. Following prioritization, the number of boreholes reduced to 14 wells to meet cumulative total demand of about 172 lt/sec. Accordingly, collector, transmission and distribution lines with storage and collector and transfer reservoirs, and EM Components as summarized below are presented.
