Abstract
Automation is an essential part of producing drinking water in the necessary quantities at the right time with high levels of efficiency in water production, energy and chemical materials consumption. The primary objective of this paper is to propose strategies for controlling the sucking pumps operation system to supply the Bait-Elmal area in Khartoum State. The proposed system works as follows: Pumps are placed on a floating lunch joined to Shambat Bridge. Then, the operating system of these pumps is controlled by Programmable Logic Controllers (PLCs) to suck water from the Blue Nile River. The Reservoir water level is controlled by programming the working and standby pumps using level sensors installed inside the water reservoir. Practically, a control system has been applied to control the pumps' operation system. The water level in the reservoir is monitored and controlled by using two (high and low) level sensors connected to the sucking water pumps via PLCs. In summary, a complete control system has been successfully tested, where the sucking pumps are installed to supply the Bait-Elmal water plant from the Blue Nile. The results obtained prove the reliability and applicability of the system with more advantages in this area or any similar drinking water plant.
