Marrakech Wastewater Treatment Plant (WWTP) with biogas recovery for cogeneration:
Marrakech Wastewater Treatment Plant (WWTP) with biogas recovery for cogeneration. The Marrakech WWTP is located north of an industrial area and south of the public landfill. The technology employed consists on an aerobic treatment of wastewater in three steps and an anaerobic treatment of sludge in a mesophilic digester with biogas (CH4) recovery for cogeneration of electricity and heat for the Marrakech WWTP. The produced electricity is used in the plant and replaces a part (33%) of the WWTP’s electricity consumption from the national grid. The heat is used for maintaining a stable thermal environment in the sludge digester which is necessary for the chemical process of sludge digestion. Treated water going through tertiary treatment is used for irrigation and surplus treated water is rejected in the Oued Tensift river bed after secondary treatment. This aerobic WWTP with sludge digestion for methane production for energy generation implements uncommon, high technologies for Morocco, which contribute not only in themselves to technology transfer but also to capacity building in this sector.
Duration of the tour: a half day (09h - 12h)

Haouz plain around Marrakech with various aspects of water resources and their uses

1) Various irrigation systems present in the area (traditional irrigation, modern gravity irrigation, groundwater extraction) and their linked stakes. The area is experiencing a massive conversion to drip irrigation, fostered by the “Plan Maroc Vert” (Green Morocco Plan).
2) Agro-hydrological study sites of the TREMA joint international laboratory. The objective of these experiences is to study the hydrological functioning of crops in order to provide information to the water managers to optimize the water use. We will visit a “flux measurement setup” located on the major crops encountered in the area (wheat, tree crops) allowing monitoring of the various fluxes linked with the crop functioning (transpiration by the vegetation, evaporation of the soil, deep percolation through the soil, etc.)
3) A setup for flash flood alert on one of the main rivers issued from the High Atlas Mountains, and possibly some scars of the 2014 flood.
Duration of the tour: a half day (14h - 18h)
