Borehole F5 at Kirène site

01Context

The Kirène plant needed to secure its water supply through a new borehole.

The reliability of the facility required hydrogeological study and rigorous monitoring.

02Challenges

Mobilising and sustainably securing the resource requires precise knowledge of its geometry, productivity and quality.

The challenge was to strengthen decision-making by reducing hydrogeological uncertainties.

03Mission objectives

• Assess the site's geophysical data
• Design the borehole technical cross-section
• Develop the detailed design and cost estimate
• Supervise implementation up to the pumping test

04Services delivered by EAU-GEF

• Evaluation of the geophysical report
• Technical design and detailed drawings of the facility
• Support for contractor selection
• Supervision, control and technical report of the borehole

05Approach & methodology

The approach combined desk review, field investigations, geophysics and hydrogeological interpretation to clarify system functioning.

Results were spatialised to objectify decisions and guide facility design.

06Results & added value

The mission provided the client with a solid, well-documented basis for sustainable management and development of the resource.

It demonstrates EAU-GEF's expertise across the entire hydrogeological study chain.
