Somalia: Hydro-geological/Geophysical Survey

ORGANIZATIONAL BACKGROUND

Adeso is an expanding and vibrant African based international development and humanitarian organization. At Adeso, we work with African communities who are yet to realize their full potential; working inside these communities to create environments in which Africans can thrive. Our belief that economic, social and environmental security is the bedrock of a healthy community drives the nature and intent of our programming. We work to prevent and overcome situations that adversely affect community well-being by: reinvigorating the economy, developing skills for life and work, providing humanitarian aid, and influencing policy.

For the past 20 years we have strengthened rural livelihoods through environmental awareness, training, technology transfer and innovative humanitarian projects in pursuit of a peaceful, self-reliant, and greener future.

PROJECT SUMMARY

Adeso is currently implementing WASH project for vulnerable communities in Lower Juba. The overall objective (Goal) of the project is to improve quality of health among children and women by building community resilience to cope with the effects of drought through increasing access to safe water supply and sanitation services, and improving hygiene behaviours for vulnerable populations in Lower Juba region. Generally the region remained peaceful for the last 2 month despite preparation of AMISOM forces to attacks and liberate the remaining areas under the controlled of Al-Shabab in the region, however there is normal follow of traffic movement from Liboi to Degelima as there is frequent movement of KDF to and from the proposed site.

In this regard Adeso is sourcing for the services of a hydro-geologist consultant to conduct a comprehensive Hydro-geological/Geophysical Survey and related studies (EIA) for the borehole. Below is the GPS coordinate for Degelima village.

BACKGROUND FOR CONSULTANCY

The purpose of the hydro-geological /geophysical survey is to explore the possibility of identifying the needs of a groundwater source for the drilling a borehole for the community of Degelima village. The Survey will aim at evaluating the groundwater situation as it is, through collecting any available relevant data (e.g. drilling logs), evaluating data from the surrounding boreholes, carrying out field geophysical measurements and reviewing any available previous survey report to form the hydro- geological geophysical survey report which will be in accordance to standards set and will meet Adeso, Donor, Government and community objectives of drilling a successful borehole that will provide sufficient water for domestic and livestock use of the targeted beneficiary community.

SCOPE OF WORK

The Consultant is 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 and satellite images while primary data will be obtained by carrying out Hydro-geophysical measurements as well as study of topography and vegetation within the study area using the necessary hydro-geological equipment.

The borehole shall be sited with the aid of combined a hydro-geological and geophysical survey. Prior to the field investigations, a desk study shall be made of the available relevant information on hydrogeology including seasonal variations, climate, existing water sources, drilling records and other sources for the proposed area

The field investigations MUST be undertaken by a registered hydro-geologist, assisted by highly qualified hydro-geologists. The registered hydro-geologist will be responsible for planning, execution and interpretation of all geophysical data, reporting, selection of the most suitable site for drilling and making recommendations on the most suitable type drill to be used

The site for selected development shall be marked with a concrete marker, shown in a picture plate and indicated on a sketch map to be included in the final report with GPS coordinates clearly indicated

The outcome of the consultancy will be a detailed hydro-geological survey report giving details of the findings and recommendations In addition to conducting an EIA that should adapt the Kenya Standards and any other international good practice.

SURVEY APPROACHES AND DELIVERABLES

1. The hydro-geological/geophysical investigations will be carried out in a multi-step methodology.
2. Literature review: Review of existing data, topographical maps, satellite images, existing studies and borehole site investigations in the area, geological reports and maps (if available), borehole and surface water records, etc. The desk review should also establish existing micro financial mechanism available for WASH service delivery; this should include both ongoing practice and what microfinance institutions are rolling out in the market.
3. Activity completion report with design and installation details
4. Copy of standard chemical water quality test water result from a nearby borehole
5. Identify social economic opportunities that exist in the identified project locations and how they can be applied/ integrated in WASH service delivery to achieve delivery of WASH services to the people and contribute to the wellbeing of residents.
6. Establish from existing information the gaps in water supply, Sanitation infrastructure and hygiene behaviour and any recommendations that exist on strategies for scale up in provision of WASH services and their sustainability.
7. Establish and outline existing market based approaches in WASH service delivery within the proposed project location.
8. Identify proven and tested best practices and approaches that can be replicated in the project implementation.
9. Hydro-geological fieldwork: Detailed reconnaissance survey of project area. (GPS co-ordinates/P-codes, water level measurements, condition of these boreholes, usage and performance where applicable) inspection of geological, geo-morphological and structural characteristics of the investigated area; verification of existing data and findings.
10. Analysis of hydro-geological/geophysical data.
11. Compilation, analysis, and evaluation of the gathered data and information.
12. Borehole design.
13. Site selection and reporting.
14. Presentation of the final report to the project teams in Adeso HQ in Nairobi.

REPORTING

The final report to be submitted to Adeso will be a comprehensive account of the whole of the Consultancy; it will review the existing literature and other relevant information, such as drilling logs, satellite images etc. The report shall include all field data, interpretations and justifications, hydro-geological evaluations, conclusions and recommendations relating to the investigated area. In addition, appropriate maps, diagrams and data plots shall be presented. Of considerable importance will be an objective assessment of the applicability and success of the methods applied.
