Hydrogeological/Geophysical Survey & Borehole Drilling in Eyl district

Location: Eyl District, Puntland State, Nugaal region, Somalia

  1. Background

Action Against Hunger is one of the major humanitarian actors in Somalia since May 1992. Action Against Hunger entry into the country was as a result of a major famine outbreak in 1992, which claimed many lives. During its 19-year presence, ACF has provided support in Nutrition; Health; Water, Sanitation & Hygiene; and Food Security and livelihood sectors in six (6) regions namely Galgaduud, Banadir, Bakool, Gedo, Bay and Nugaal regions. Currently, ACF is present in three regions of South-Central Somalia namely Bakool, Banadir, and Lower Shabelle and also in Puntland (Nugaal region). In 1995, due to overwhelming humanitarian needs in Mogadishu, ACF launched a health and nutrition programme in the city, which has been running to date. With deteriorating humanitarian situation in South- Central Somalia in 1999, ACF responded to the crisis by opening a base in Luuq (Gedo region) and five years later opened operations in Bakool region, which continued to run to date. Operations in Lower Shabelle and Nugaal regions were opened in 2013/14. ACF has developed programmes in nutrition, health, food security and WASH sectors in these areas.

1.1 Location

Qarxis is one of the villages under Eyl district administration, Nugaal region. The village is 90km away to the northeast of Eyl and approximately 150km from Garowe. It sits at an altitude of 7.97824 N 49.815986 E. The village is generally hot, sunny, and dry and has an estimated population of 4,800 that are purely dependent on livestock rearing with a number of undocumented daily pastoralist movements. The village is located at an intersection and serves as a hub to remote villages of the district. It hosts pastoral dropouts who lost their assets and livestock during the recent cyclone and shocks that affected their livelihoods. The village had been experiencing shortage of water due to constant rain failure. Scarcity of water is a major challenge for Qarxis community and the neighboring villages and all depend on the stored seasonal water from the barkeds. However, the Qarxis communities yearn to one day  have access to sustainable water infrastructure (boreholes) that can reduce the water needs and further improve access to water for multi uses. The main source of livelihood for the community is livestock accompanied by small-scale businesses.

1.2 Project Description

The SomReP project funded by SDC in Eyl district is a multi-year resilience building project whose goal is to increase the resilience of chronically vulnerable Somali people, households, communities and systems to climatic shocks and other related risks in targeted pastoral, agro-pastoral, coastal, and peri-urban livelihood zones by 2023. CAAP process supports communities to identify water points to rehabilitate, construct, and upgrade to improve their resilience within the framework of a district-level strategy.

The multi-use water infrastructure activities under the SDC Project include:

  • Hydrogeological survey (6 sites to be investigated)
  • Drilling and equipping of one borehole (multi powered)
  • Construction of elevated water tanks 50M3
  • Construction of distribution infrastructure (4 Water kiosks, 3 animal troughs and piping works)
  • Water conservation infrastructure rehabilitation/construction (Berkads)

To ensure sustained access to water for the populations in Eyl, ACF plans to drill a multipurpose water borehole in the district supported by SDC. The BH is expected to serve the neighboring villages especially as a filling point for water bowsers during dry seasons.

In this regard, ACF is sourcing for a drilling company with capacity to conduct a comprehensive Hydro-geological /Geophysical Survey and related studies for the area (including neighbouring villages) and to subsequently drill a productive borehole. The purpose of the hydro-geological /geophysical survey is to explore the possibility of identifying a groundwater source for the Eyl rural communities. The survey aims at evaluating the groundwater situation as it is, through;

  1. Collecting any available relevant data (e.g. drilling logs, use of local knowledge from the team of local experts),
  2. Evaluating data from the surrounding boreholes,
  3. Reviewing available previous hydrogeological survey reports from the neighbouring districts
  4. Carrying out field geophysical measurements and
  5. Prepare the survey report which will be in accordance with standards set in this ToR and shall meet ACF, Donor, Government and community objectives of drilling a successful borehole that will provide sufficient water for domestic and livestock use.

To support the survey ACF will consult with the beneficiary communities, government representatives and local experts to identify 6 potential sites for a new borehole (however, these locations can be modified by the consultant depending on desk and field level studies).

  1. Overall and specific objectives of the Consultancy work

The overall objective of this study is to conduct comprehensive Hydro-geological /Geophysical Survey in Eyl District. 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 while primary data will be obtained by carrying out Hydro-geophysical measurements within the study area using the necessary hydro-geological surveying equipment.

The outcome of the consultancy will be a detailed hydro-geological survey report giving details of the findings and recommendations

  • Specific Objectives:
  • Document existing knowledge on abstractions and ground water in the area (make use of information provided by the local team of experts)
  • Undertake geophysical survey for 6 locations identified by ACF. For each site assess feasibility and if possible recommend installation depth for pump and estimated yield
  • Prepare water balance for the area and identify safe level of water abstraction
  • Prepared summary of areas hydrogeology and geology including major faults
  • Prepare indicative construction BOQs and drawings for new water points
  1. 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 co-ordinates/P-codes, water level measurements, condition and performance 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.
  • Geophysical survey at 6 sites (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
  1. Expected output of the consultancy
  • Hydrogeological report including
    • Desk review of hydrogeology, geology (identify potential faults
    • Overview of existing abstractions in Eyl District
    • Geophysics investigation results for proposed locations detailing proposed drilling depth and pump installation depth
    • Analysis of the geology, based on desk study, current abstraction and geophysical investigation develop Water balance, set maximum abstractions for proposed boreholes and prepare recommendations for future drilling.
  • Recommendations report prioritizing the boreholes, rehabilitations needed for the existing boreholes BOQ and drawings for the new borehole (including drilling, pump installation, solar array and tap stands/troughs)
  • The successful execution of the geophysical survey will lead to BH drilling discussions.
