Project description
The ORMVAH (Haouz Regional Office for Agricultural Development) covers an area of over 660,000 ha, 145,000 of which have been the object of hydraulic development projects. Large-scale hydraulic infrastructures exist in three different zones : central Haouz (including N’fis), upstream Tessaout and downstream Tessaout.
This study aims to modernise control systems on three of the canals managed by the ORMVAH:
- The Canal de Rocade, 118 km long and designed for a 20 m³/s flowrate
- The N’fis canal, 16 km long (including 11.5 km of galleries) and designed for an 8 m³/s flowrate
- The Tadla-Tessaout Canal (also referred as the T2 canal), 93 km long, which transfers water from the Bin El Ouidane plant to the downstream Tessaout irrigation zone in the El Kelâa des Sraghna area. The flowrate at the head of the canal is 12 m³/s.
The Rocade and N’fis canals are now properly controlled, but still operated by a remote management system set up 30 years ago and partially refurbished 15 years ago. This project concerns the replacement of remote-control equipment and optimisation of canal management in order to ensure that the control system operates as efficiently as possible.
The project consists of 3 phases:
- Phase 1 – Analysis of the current situation
- Phase 2 – Recommendations for improvements, including alternatives
- Phase 3 – Detailed preliminary design and tender documents
