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.

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 intaccount the available sources of energy.
• Design an appropriate storage and reticulation system.
• Expected output of the consultancy

Hydrogeological report including

• Desk review of hydrogeology, geology (identify potential faults
• Overview of existing abstractions in the area
• 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 geophycail investigation develop water balance, set
• Recommendations for borehole development, tinclude but not limited to, the following:
• Locations of recommended borehole expressed as a coordinate(s) and indicated on a sketch map
• Recommendations regarding borehole or well density and minimum spacing in the project area
• Recommended depth and maximum diameter.
• Recommended construction characteristics, e.g. wire-wound screen, grouting depth
• Anticipated yield
• Any other relevant information (e.g. need tmonitor neighboring boreholes during tests)

Environmental Impact Assessments including

• Assessment of potential impacts that may occur at all phases of project.
• Provide potential effects of the project and propose suitable mitigation measures.
• Develop environmental management and monitoring plan.
• Provide decommissioning/rehabilitation plan
• BOQ and drawings for the proposed borehole development (including drilling, pump installation and water reticulation).
• Supervision drilling – the consultancy costs tinclude the costs of borehole drilling supervision on your bid.
