摘要：In the Middle East and North Africa, small communities have virtually no access to centralized wastewater collection and treatment systems. In the absence of such services, sewage disposal is often left to the discretion of homeowners. In many cases, untreated sewage is discharged into surface waters or the landscape, contaminating already dwindling surface water and groundwater resources. This practice will continue unabated unless appropriate and affordable treatment systems are made available. The project will develop, test and promote low cost sustainable technologies for decentralized wastewater treatment through a partnership of local communities, research institutions, government and businesses. In order to study the multi-soil-layering system (MSL), which was installed for the first time in Morocco, four laboratory-scale MSL systems were built and monitored. The first small scale pilot, which was 30 cm deep, 36 cm wide, 65 cm high and a hydraulic loading rate (HLR) of 200 l/m 2 /day. The three others were installed at the village Talat Marghen under the Aghouatim rural community in Marrakech governorate in Morocco. They are cylindrical plastics with a height of 65 cm and a diameter of 41 cm. with different hydraulic loads of respectively 250, 500, and 1000 l/m 2 /day. The results of the technologies piloted implemented in Morocco will be study, according to technical criteria. The project asks for the best way to adapt the wastewater treatment systems for small communities in MENA region and some part in Africa
