Science and regional knowledge, working together
Biyosahan is a Somalia-based professional consulting firm specializing in water resources science, hydrogeological modeling, climate risk assessment, and technical capacity building. We combine scientific expertise with deep regional knowledge to deliver practical, high-impact solutions tailored to the East African context.
Our vision
To be the Horn of Africa’s most trusted hydro-technology and water-resources consultancy.
Our mission
Science-driven water, GIS and environmental solutions that reduce risk and strengthen local capacity.
Why Biyosahan
Why organizations choose us
Internationally recognized hydrogeological methods, delivered by a team that knows Somalia and the Horn of Africa.
Mogadishu, SomaliaWorking across Somalia & the Horn of Africa
One team, from field to decision
Pumping tests, monitoring, modeling, GIS and reports all come from one team, so nothing gets lost between steps.
Built for Somalia's water
Based in Mogadishu, with work on the Juba and Shabelle basins, coastal aquifers, and water for pastoralist and farming communities.
Standard tools you can check
MODFLOW 6, PEST, GW Vistas, ModelMuse, QGIS and Python. Recognized methods your engineers can review and reuse.
Your team keeps the skills
Hands-on courses from pumping tests to model calibration, so your people can run the work after we finish.
