Exploitation of karstic aquifers in Algeria Somes difficulties are specific of the karstic aquifers (hardness of the rocks, depth of the water table, scattering of the clefts). The new drilling technics (downhole hammer) solve some of these difficulties and many mediterranean countries prospect now such aquifers. They contain very fresh waters, even in arid areas. The deep tube wells are now cheap and easy to elaborate. Depending of the geological structure, the hydrogeological behaviour will be different (with more or less permanent water stocks). Some algerian examples show how the development plan must be adjusted to this structure.Les aquifères karstiques présentent pour l'exploitation certaines difficultés particulières (roche dure, ...
