Water quality has an important impact on human health since different diseases can be the result of poor quality. This paper presents several strategies to manage water quality in order to protect human health by building a decision support system to help the authority of water supply stations to find information about water management. The water quality service uses a set of (13) water-quality parameters according to the water quality index (WQI) analysis. The system suggests a decision for treatment the water so that it can be used by humans after detecting the causes and type of pollution. Water quality DSS tests the data from the water management stations using mathematical models. In this paper we use Machine learning and Data mining to build the decision making system.</p></abstract><trans-abstract xml:lang="en"><p>The main issue addressed in our case study is the evaluation of the drinking water resource.
