Abstract

Axum has scarce water resource. At present, there are four wells and a dam that are supposed to supply water from aquifer and provide a barrier constructed to hold back water to the public through the water distribution network. However, the pumping stations at these wells and dam along with the distribution network were managed manually by operators in a primitive manner. During peak consumption periods, which may last for weeks, water was not delivered to wide areas and the resources were not distributed evenly to public. Operators tried hard to achieve fairness by manually controlling gate valves along with pumping stations. Therefore, to overcome these problems, a Supervisory Control and Data Acquisition (SCADA) system to be used to manage the water pumping stations in Axum has been designed. Moreover, this thesis introduces a report mechanism by modeling the existing water supply system which controls loss of data and reduces the loss of water. To obtain accurate data analysis, this work was presented using a LabVIEW software simulation. And also, this system is expected to increase customer satisfaction, reduce water distribution cost and provide an accurate overview of the plant‟s operations. Furthermore, SCADA stores valuable information about the water system performance; and this data is necessary for efficient development of the existent distribution system in a way that met population growth.
