2 MISSION As part of the hydro-agricultural development project of the irrigation perimeter of Dar Khrofa, located in the province of Larache, AMITECH MAROC s mission is the supply and installation of GRP pipes for the conveyance and distribution of raw water. The implementation of the Dar Khrofa Dam and the hydro agricultural development at its downstream are part of efforts to pursue the development and enhancement of the main economic activity of the region of Loukkos : Agriculture. This development will be achieved through the mobilization of new surface water resources and the promotion of irrigated agriculture in the Green Morocco Plan. The Dar Khrofa Dam, with a capacity of 480 million m³, will regularize 140 million m³ per year, of which 130 million m³ / year as an agricultural annual allocation, to ensure the irrigation perimeter. The work area is part of the irrigation perimeter of Dar Khrofa which consists of 12 sectors, with a total net area of approximately ha. The GRP pipes used for this project have a total length of 99,50 Km, nominal diameters from 400 mm up to 3000 mm and a stiffness of.
