Action Against Hunger USA
Program: WASH
Project: Building Resilience Among Drought affected communities in Isiolo (BREAD-II) Counties, Kenya
Area: Isiolo County – Oldonyiro ward.
- Background
Isiolo County faces significant challenges due to recurring disasters, leading to increased food insecurity and malnutrition. The Long Rains Assessment (LRA) report from August 2023 revealed that over 79,000 people were categorized under IPC 3, a number expected to rise due to floods displacing households. The LRA report also notes the critical nutritional situation, with the county classified at IPC 4 for Acute Malnutrition and a Global Acute Malnutrition (GAM) rate of 15.4% based on the February 2023 SMART survey.
To address these issues, it is crucial to implement innovative technologies and approaches for food production. This will help communities adapt to and recover from severe climate shocks, promoting long-term resilience and climate-smart agricultural practices. Additionally, providing sustainable water solutions for various uses, including domestic, agricultural, livestock, and institutional purposes, is essential for enhancing household food security and mitigating malnutrition in Isiolo. Action Against Hunger is seeking a registered and licensed company to conduct Hydrogeological assessment and Environmental Impact Assessment (EIA) for the proposed boreholes in line with the information provided below.

2**. Overall and specific objectives of the Consultancy work**
The overall objective of this study is to conduct comprehensive Hydro-geological /Geophysical Survey in three sites within Tuale Location, Oldonyoiro ward in Isiolo County. The Consultant/s are expected to use both secondary and primary data in the exercise; Secondary data will involve desk study of available information/data on existing boreholes, drill logs, reports and maps while primary data will be obtained by carrying out Hydro-geophysical measurements within the study area using the necessary hydro-geological surveying equipment preferably using a combination of seismoelectric and other methods. With the obtained hydrogeological data, the consultants will propose the most economical water abstraction and reticulation system.
The outcome of the consultancy will be a detailed hydro-geological survey report giving details of the findings and recommendations.
2.1 Specific Objectives
• Document existing knowledge on abstractions and ground water in the area
• Undertake geophysical survey for three location within the target sites. For each site assess feasibility and if possible, recommend the best site with installation depth for pump and estimated yield
• Prepared summary of areas hydrogeology and geology.
• Undertake Environmental Impact Assessment project summary for the proposed project at the school.
• Propose the most economical water abstraction, storage and reticulation system.
• Prepare construction BOQs and drawings for recommended borehole site.
3. Scope of the Work
The hydro-geological/geophysical investigations will be carried out in a multi-step approach;
• Desk study: Review of existing data, topographical maps, satellite images, existing studies and borehole site investigations in the area, meteorology, geological reports and maps (if available), borehole and surface water records, etc.
• Hydro-geological fieldwork: Detailed reconnaissance survey of project area. (GPS coordinates/P-codes, water level measurements, condition and performance of these boreholes, usage and performance where applicable) inspection of geological, geomorphological and structural characteristics of the investigated area; verification of existing data and findings.
• Geophysical survey at the site specifically seismoelectric with other methods (resistivity/IP profiling or vertical electrical/IP soundings)
• Analysis of hydro-geological/geophysical data.
• Compilation, analysis, and evaluation of the gathered data and information.
• Site selection and Prepare recommendation report
Water abstraction, storage and reticulation system.
• Estimate the daily water demand for the community
• Design the most economical water abstraction system taking into account the available sources of energy.
• Design an appropriate storage and reticulation system.
4. Expected output of the consultancy
• Hydrogeological report including
o Desk review of hydrogeology, geology (identify potential faults
o Overview of existing abstractions in the area
o Geophysics investigation results for proposed locations detailing proposed drilling depth and pump installation depth
o Analysis of the geology, based on desk study, current abstraction and geophycail investigation develop water balance, set
• Recommendations for borehole development, to include but not limited to, the following:
o Locations of recommended borehole expressed as a coordinate(s) and indicated on a sketch map
o Recommendations regarding borehole or well density and minimum spacing in the project area
o Recommended depth and maximum diameter.
o Recommended construction characteristics, e.g. wire-wound screen, grouting depth
o Anticipated yield
o Any other relevant information (e.g. need to monitor neighboring boreholes during tests)
• Environmental Impact Assessments including
o Assessment of potential impacts that may occur at all phases of project.
o Provide potential effects of the project and propose suitable mitigation measures.
o Develop environmental management and monitoring plan.
o Provide decommissioning/rehabilitation plan
• BOQ and drawings for the proposed borehole development (including drilling, pump installation and water reticulation).
• Supervision drilling – the consultancy costs to include the costs of borehole drilling supervision on your bid.
