Currently, because of the daily human waste to environment, the water, the air breathed by humans are not clean. Even though most developed countries are having improved system of wastewater treatment system, the treatment process is done partly by human and sometimes problem can occur during the process which reduces the quality of the effluent wastewater. In order to overcome human errors, the use of digital computer to control the process of the wastewater treatment processes is needed. This report discusses about the process of wastewater treatment process and how to design the automated control system for the system. Domestic wastewater can be treated in many ways: physical, chemical and biological unit processes. Since the wastewater treatment process is vast and at the same time, the most important process in wastewater treatment, activated sludge process, will be discussed. Automated control system design for the plant is also built using activated sludge wastewater treatment process
