It becomes therefore necessary to install mechanisms and actions aiming at preserving and safeguarding the quality of water resources. The prevention of the contamination on a local scale requires the establishment of protection perimeters around the wells. The use of geographical information systems (GIS) for the management and the handling of information is necessary because of the geo-referenced nature of the data. The main purpose of this study is the design of a GIS for delineating protection perimeters (DPP). The procedure used consists in analyzing and defining the needs and means necessary for designing the GIS and for developing the processing system for the DPP of groundwater resources (principal information layers and functionalities of the system). Finally, to assess the reliability of the system suggested, an application was tested on the Ahmed Taleb Field basin located in the North-East of Kenitra city (Morocco). A toolbox was developed in order to carry out some of the operations required (feed area, influence and draw zones, transfer time) for dimensioning the various protection zones (immediate, influence and distant protection zones). The methodology utilized in this pilot project will be used as a guide for the future cartography of the vulnerability of the aquifer system and for the delimitation of protection perimeters in order to ensure the effective preservation of water resources geared to the drinking water network.
