Since groundwater is the main water resource in Libya, groundwater information system GWIS is required as a decision support system, where it promises great potential for effective management and assessment of groundwater resources, and enhances the sustainability and efficient use of groundwater resources. This paper discusses the requirements and the design approach for the preparation of GWIS using geographic information system GIS techniques, where Al Waseetah area in Al Jabal Al Akhdar region was selected as a case study because of the availability of the hydrogeological data. The system structure and characteristics were defined and designed to store and manipulate the groundwater data, where 155 groundwater wells data were used to test and implement the GWIS system, in addition to remote sensing data as well as previous geological and hydrogeological studies. A series of maps and the hydrogeological map were produced and used to evaluate and interpret the groundwater system in Al Waseetah area.
