The aim of the  study was to describe water sources of Sadat city, Menoufia, Egypt. Monitoring support wells, artesian plants, and surface source which play an important rule in water quality as well as networks was run for 6 years from 2012 to 2017. The results showed the surface water source had fixed total dissolved solids (TDS) over the study years with an average of 272 ml/L. For the northern wells, TDS ranged from 397 mg/L to 546 mg/L with an average of 482 mg/L over a study period. For the southern wells, the TDS ranged from 703 mg/L to 1142 mg/L and had gradually increased due to overuse and uncontrolled water withdrawal from wells pumped into the reservoir, which supplies water to residential areas. The water of Sadat city especially in case of southern wells has no considerable potentials of groundwater resource.  In addition, the water quality of distributed ones showed the most areas were supplied with water through the northern and surface stations had acceptable quality according to Egyptian guideline except the first and second residential areas.
