Constructed Wetlands as an Environmental Friendly System for Wastewater Treatment in Al Akhawayn University

The environment is continuously deteriorating due to the irresponsible acts of humans toward nature. One of these reckless actions is the discharge of wastewater without treatment. Wastewater encloses many toxins which represent a threat to the environment and humans as well. There exists a conventional method of wastewater treatment that is widely used around the world; however, new eco-friendly unconventional methods have been used for the same purpose, namely, constructed wetlands that will be used for this project. The objective of this study is the design of a constructed wetland system to treat the wastewater originating from two buildings that hosts 500 residents on the university campus. The total amount of influent is approximately 22.5 m3 per day. The influent will be primarily treated by going through a septic tank and then distributed among five equal wetlands of 400 m2 each. SubWet is the software used to experiment with the different design scenarios; it also generates the removal efficiency of some contaminants such as BOD5 and nitrate from the wastewater which varies between 99.5% and 100% efficiency. Last, but not least, a financial study was conducted to determine the costs and the payback period that yielded to 6 years.
