TN-GEF Northern Tunis Wastewater Project

closed

The objectives of the Northern Tunis Wastewater Project for Tunisia are to: (a) provide an environmentally safe disposal system for the treated wastewater which will not be reused in agriculture in the North of Tunis; and (b) increase the quantity and quality of treated wastewater made available to farmers to encourage its reuse in agriculture in the Borj Touil area. There are three components to the project, the first component being transfer of Treated Wastewater (TWW) to increase its reuse in agriculture. This component will focus on the investments necessary to transfer the TWW from its existing discharge point close to the El Kehlij agriculture drainage canal up to a storage basin, from which it will be made available for reuse in agriculture. The Global Environmental Facility (GEF) grant will finance a portion of the investments under this component. The second component is the improvement of the discharge of the remaining TWW in the Mediterranean Sea. This component aims at developing the infrastructure necessary to improve the discharge of the remaining TWW in the Mediterranean Sea. Activities under this component include: TWW transfer; submarine outfall; and studies. Finally, the third component is the monitoring and capacity strengthening. This component will fund important accompanying measures for the implementation of the project, including consulting services to strengthen: (i) water quality monitoring systems in the project area; and (ii) coordination mechanisms among agencies involved in wastewater reuse, in particular Tunisian National Sanitation Utility (ONAS) and Ministry of Agriculture, Hydraulic Resources and Fisheries (MARHP).
