Ecological Solution for Golf Course Irrigation in Fez – Greywater Treatment Using a Constructed Wetland

Golf courses in Morocco are known for their excessive consumption of drinking water for irrigating the green areas, leading to significant wastage. This article presents an ecological solution for treating wastewater from homes using constructed wetlands (CWs). The treated water is collected in a water reservoir. Among the key parameters, determining the evapotranspiration (ET) of the treated water in CWs poses a challenge for designers. To address this issue, a practical and adaptable method has been developed, taking into account various factors such as plant type, growth period, watering frequency, weather conditions, and the size of the CWs substrate. Finally, the application of the proposed methodology for designers of subsurface flow CWs is illustrated through a case study of a golf course in Fez.
