Due to the explosive population growth, the demand of adequate hygiene drinkable water has been increased. Therefore, it has become more necessary to apply the automatic control system for water treatment production, in order to attain the health required outcomes. According to complexities of the process and the intersection of the treatment states, the suggested methodology in this chapter anticipates for the development of an automatic control based on wireless sensing networks (WSNs) to be applied in water treatment process. The wireless automatic systems are deployed in order to manage the processes of the production and increase the efficiency to the maximum level, along with the minimum cost. It is, therefore, important that the automated system works professionally, in order to get the utmost profit from the processes of the production. Practically, an effective control models have been designed and implemented using simulation software. Therefore, the research successfully managed to automatically control in the working pumps operation. The addition of purification and disinfection chemicals doses successfully calculated and added to the water in a real-time operation mode. In filtration phase, the process of filters backwashing has been completely automated. The obtained results were essential, beneficial and prove the system's applicability with minimum cost.
