Project Description
This first project will focus on the execution of the new wastewater treatment plant in the North of Greater Tunis (also called El Hessiane WWTP) located in the North of Greater Tunis to meet the required capacity needs for the next 20 years. As per ONAS masterplan study, it is required to increase the hydraulic capacity by an additional 60,000 m3/d to meet the planned demand in line with the forecasts for the year 2035. Based on the studies, it has been decided to establish the new North WWTP in El Hessiane area, as there is a land available for building the new station away from the urban areas. Constraints were found in relation to soil characteristics and the need for deep foundations during construction works. There are opportunities for reuse of treated wastewater from the North wastewater plant in the existing Cebela-Borj Touil perimeter, which is the largest irrigated perimeter from treated wastewater in Tunisia. This perimeter, created in 1989, covers a total gross area of 3200 ha and is fed from treated wastewater produced by the three wastewater treatment plants of Cherguia,Choutrana (I and II) and Coastal North. As per the updated studies, there is a planned extension for the irrigated perimeter of Borj Touil, and therefore, there is a potential for the use of wastewater processed from the new North WWTP.
