Wastewater treatment for agricultural use with minimal Greenhouse Gaz Emission in Asselda Village, Morocco

Asselda is a Berber village with a predominantly agricultural economy at the foothills of the Atlas range south of Marrakech, in semi-arid climate. It is home to 250 families (1200 inhabitants) half of which traditionally own fruit tree plantations. These are irrigable with river and ground water through irrigation canals during spring and early summer months. The homes are supplied with piped groundwater from the shallow aquifer and equipped with pour-flush toilets. Prior to project implementation, untreated grey and black water was discharged through open drains and used for fruit tree irrigation. The practice brought with it considerable health risks for farmers and farmers’ adolescent children working in the plantations. The risk of ground and drinking water contamination was imminent. The project in Asselda became operational in February 2015. It comprises a renewed and extended low-cost sewerage system, a gravity-fed wastewater treatment plant consisting of 3 vertical-flow reed-bed filters (first of its kind in Morocco), a facultative stabilization and a treated wastewater storage pond, and a solar-powered irrigation system. The newly installed infrastructure enables families to irrigate up to 3 ha fruit tree plantations year-round with risk-free wastewater, and hence, to increase the family's income. The improved wastewater system reduces risks of aquifer and drinking water pollution, and thus reduces health risks. The wastewater treatment plant can treat 45-50 m3 of domestic wastewater per day and therefore provides 1350-1500 m3 of safe irrigation water per month. Vertical-flow reed bed filtration - the main treatment step in Asselda - is a predominantly aerobic process. It therefore produces considerably less greenhouse gas than an equivalent pond system, in numbers 210 tons of CO2 emissions per year. The completed project serves as a model for replication in numerous other small communities in Morocco and elsewhere in Maghreb countries.
