To upgrade of the WWTP at Korba, Tunisia, to reuse treated water for aquifer recharge;
To increase water availability for agricultural activities in the targeted regions, and thus reducing the current over exploitation of drinking groundwater.
Preparation of tender documents and launch of the project
Consultation of contractors
examination schedules of conditions and establishment of the markets for the realization of projects
Upgrade of the WWTP for improving the monitoring of the plant and to solve some potential criticality;
Improve water circulation conditions in the maturation ponds by building walls or by installing a turbine so as to eliminate dead spots, reduce the variability of the hydraulic residence time in the ponds and, therefore improve the quality of water for groundwater recharge.
Increase the capacity of the pumping station from the WWTP to the recharge basins from 1,500 to 3,000 m.
Build 3 additional infiltration basins, 1,500 m2 each, which means 4,500 m2 of additional infiltration area.
