Project description

This diagnostic and rehabilitation study covers 18 pumping and lifting stations located in the Greater Tunis region, most of which came into operation in the 1980s. It aims to upgrade these stations as well as their adaptation to cope with the evolution of the volumes of wastewater to be treated by 2026.

The objective of this project is to:

• Diagnose the condition of pumping stations and indicate various failures: degraded condition of civil engineering works, malfunction of certain equipment
• Check the capacities of the stations
• Propose rehabilitation and modernization solutions
• Propose and supervise the preparatory works (topographical and geotechnical works)
• Preparation of detailed preliminary projects and work offer files
