About SALGRID

Welcome to the Salone Groundwater Resources Database (SALGRID) portal, the official data portal and repository of hydrogeological information of the Government of Sierra Leone. SALGRID enables users to quickly and easily retrieve archived groundwater-related observations at national scale and from sites across the country. Developed for the Ministry of Water Resources and the Sierra Leone Water Company (SALWACO) and financed by the African Development Bank, SALGRID provides a suite of on-line tools, including an archive of groundwater data and a GIS-based data and map viewer.

If you are new to SALGRID, please visit the User Guide / Help Document for more information about how to use the portal. If you wish to inform us of any updated information about the lots in the database or to provide any other feedback, please contact us.

Groundwater Maps

Hydrogeologic Atlas of Sierra Leone.

The Hydrogeologic Atlas of Sierra Leone (2017) is a series of maps related to groundwater resources complemented with related thematic maps and textual notes, published in official digital and hardcopy (PDF) formats. The maps were prepared by Hydro Nova for the Government of Sierra Leone by using a geographic information system (GIS) format. Maps are at a scale of 1:650,000 or less. Click the link above to access the official maps published in 2017.

Digital Groundwater Maps (deactivated).

The SALGRID WebGIS is a tool that displays spatial data related to Sierra Leone’s groundwater resources on the Internet. It combines the advantages of both the Internet and GIS (geographical information system) capabilities. The tool lets authorized users visualize and analyze layers of information derived from the Hydrogeologic Map of Sierra Leone (2017), as well as other important spatial data on aquifers, groundwater potential, boreholes and wells. The aim of the SALGRID WebGIS tool is to provide a new capability for technicians to understand local and regional groundwater conditions throughout Sierra Leone and ultimately enhance decision making and management of groundwater resources.

*Access to the SALGRID digital map viewer is provided to authorized users only. Please contact SALGRID for more information.

Groundwater Data

Data Archive (deactivated).

The SALGRID Data Archive is a national repository of data pertaining to hydrogeological resources. The Data Archive contains datasets, both geographical (geodatabase) and non-geographical (reports, logs, studies), which have been collated and organized to facilitate access. The aim of the SALGRID Data Archive is to provide a tool for managing national groundwater data. Click the Data Archive link above to access datasets. Access is for authorized users only. Please contact SALGRID for more information.
