HYDRAULIC INFRASTRUCTURE AND PUMPING STATIONS REHABILITATION STUDY IN JENDOUBA PPI

The public irrigated perimeters of Jendouba were built at the end of the 1970s; they are irrigated with water from the Bouhertma dam, the Oued Medjerdah and boreholes. These PPIs cover an area of ​​26,400 ha and include the following hydraulic infrastructures:

• 222 km of concrete wrapped pipes (FB);
• 488 km in steel cement (AC);
• 490 on-line control units;
• 1000 protective devices;
• 2,130 emptying devices;
• 3,500 irrigation terminals;
• 6 tanks with capacities ranging from 70,000 m3 to 400,000 m3;
• 880 km of agricultural tracks
• This study was part of the improvement of PPI management and aimed to:
• carry out a detailed diagnosis of existing infrastructures;
• make proposals for the rehabilitation of infrastructures (reservoirs, tracks, networks) with reference to rational rates and standards;
• prepare the execution files and the work tender documents.
