The proposed automation solution for waste water treatment plant involves the use of a series of small control systems that run the facility, PLC (Programmable Logic Controller) continuously monitor the operation of pumps, closures and other devices, collect and execute commands coming from the higher levels, while programmable controllers (PLC) are used to control various processes based on the data and the built-in algorithm. According to the given specifications, a control panel was created in a suitable SCADA software for the control and monitoring of waste water treatment, which requires the communication between the SCADA application and local PLC controller is necessary. A program that provides the appropriate behavior of the valve, placed at the entrance and the control of the pumps was written in a ladder diagram. The alarm and monitoring system is of the highest importance. It covers the most significant facilities of the waste water treatment plant having pumping stations, reservoirs and supply lines and shows that the plant as a whole works well. If something unexpected happens ? such as a failure or a malfunction of a vital facility ? the system should register and alerts the staffs who work there.
