520			_aThe groundwater resources play a tremendous important role in the different activities that carried out in the Eastern Sahara Desert. The Egyptian government does great efforts to establish these new communities and solve any problems, which may face the investors during their work. It is obvious that the most important problems are how to get cheap, good quality and a long life water resource.This target can be achieved by two ways; namely; the good design of the production well, the continuous well-maintenance and characteristics observation. So, the present work has aimed to evaluate the water well deterioration causes as the following: Evaluation of water well characteristics or well performances, which have been assessment by applying (42 step drawdown tests) and completely data analyzed by two methods: 1. Manual method (manual calculation and graphical analysis method), 2. G.W.W software (Ground-Water under Windows; Version 1.10, Year 2005,Win.7.0 upgraded). Water well hydraulic parameters such as well loss, formation loss, productivities, efficiencies and well loss percent could be evaluated. Moreover, the most important parameters (like productivities, efficiencies and well loss percent) could be assessed and graphically illustrated perfectly, throughout the study area. On the other hand, wells classification for each hydraulic parameter (as calculations and graphical illustrations) could be obtained. Thus, the design criteria of the studied wells can be evaluated and technically investigated as a result of these assessments
