Hydraulics and Environment

This project involves a full Project Management mission covering technical studies, control and supervision of hydro-agricultural development works in the Bahr Linia area of Chad. It is part of a rural development and food security initiative aimed at harnessing water resources from the Bahr Linia basin for irrigation and agricultural development.

Scope of the PMC mission:

📐 Studies Phase:
• Topographic, hydrological and hydrogeological studies of the project area;
• Geotechnical and environmental studies (ESIA);
• Design of hydro-agricultural structures: retention dams, spreading weirs, primary and secondary irrigation canals, regulation and drainage works;
• Schematic and Detailed Design (SD/DD);
• Tender Documents (DCE): execution drawings, technical specs, BOQ, cost estimates, construction schedule.

🔍 Works Control & Supervision Phase:
• Technical and quality control of works execution in accordance with approved plans and specifications;
• Supervision of contractors on hydro-agricultural works;
• Review and approval of execution drawings and calculation notes submitted by contractors;
• Construction schedule monitoring and management of potential amendments;
• Provisional and final acceptance of works (minutes of acceptance, snagging resolution).

🌾 Infrastructure Components:
• Water mobilisation and storage structures (hill reservoirs, dams);
• Gravity and/or pressurised irrigation networks;
• Development of irrigated perimeters and agricultural land improvement;
• Ancillary works: access tracks, agricultural storage facilities, socio-community infrastructure.

This project aims to improve access to drinking water in the localities...

The project aims to improve and strengthen the rainwater drainage system in the 2nd and 6th districts of the city of Bangui in the Central African Republic.

The main objective is to:

• Contribute to the improvement of sanitary and hygienic conditions by minimizing the risks of waterborne diseases.
• Reduce the inconvenience caused by the overflow of drainage channels after the rainy season, in order to minimize disruption to affected residential and commercial areas.

The ultimate goal is to improve the quality of life of Bangui residents and strengthen the city’s resilience to extreme weather conditions.

The project aims to provide a reliable source of water for irrigation purposes in the Menzel Tmime area by constructing a pumping station on the south bank of the Lebna Dam.

The station will be responsible for pumping water from the dam and distributing it to nearby agricultural areas, thereby promoting agricultural development in the region. This project is expected to increase agricultural productivity and improve the livelihoods of local farmers by providing them with a reliable source of water for irrigation.

This project involves the construction of a drinking water supply system for the city of Bangui in the Central African Republic.

The specific objective of this project is to rehabilitate and extend the drinking water supply system of the city of Bangui.

The project components are:

• Three (03) Pumping Stations
• One (01) Compact Processing Plant 750 m3/h
• Two (02) Return Stations
• Installation of sixty (60) km of pipe

This project concerns the execution of an SP5 pumping station in the industrial area of Medjez El Bab III, including the installation and testing of related electrical and electromechanical equipment.

This area is located southeast of the city of Medjez el Beb, between the regional road RR38 and the road RR49 leading to Gaafour in the governorate of Béja. It covers an area of 102 ha and thus reinforces the existing industrial fabric (Medjez El Bab I & II).

The project components are:

• Construction of a 250 l/s sewage pumping station
• Total network length: 13,000 ml

The project is part of the Town of Gammarth’s Strategic Wastewater Plan. It is part of the national sanitation utility’s effort to improve the living conditions of the population.
This area is located south of the city of Gammarth and 20 km north of Tunis.

The project area covers an area of approximately 182 hectares.

The benefits of this project include:

• The creation of 15 new pumping stations
• Projected Global Linear is approximately 36.5 km

This project involves the development of a drinking water supply system in 11 rural areas in Manouba Governorate :

• Ain El Hwaria Zone
• The Ain Morra Zone
• The Bir Touil Zone
• The Boali Zone
• El Henna Zone
• El Hkaymia Zone
• The Henchir Ezoraya Zone
• The Maafrine Zone
• The Oued Rmal Zone
• Sidi Ali Ben Aoun Zone
• Sidi Said Zone

The overall objective of this mission is to identify the most appropriate solutions for the realization of drinking water supply systems for these areas, in order to meet the needs of the final beneficiaries.

These solutions are based on technical and economic criteria, taking into account the need for sustainable management of available water resources and total respect for the environment.

The mission involves repairing aqueducts N°1 and N°2 of the Madjerda canal located at Cap Bon in the Governorate of Nabeul and the Béjaoua pumping station.

The main objective is to determine the most suitable technical and economic options for rehabilitating the large Madjerda irrigation canal and constructing a new pumping station.

The project aims to develop a drinking water supply system for the Ouled Achour, El Fateh, and El Ketitir complexes south of Kairouan Governorate.
The project is part of the improvement of the drinking water supply system in the region.

The work of this mission can be summarized in:

• Construction of two (02) 500m3 and 1000 m3 semi-underground tanks
• Construction of two (02) pump stations
• Construction of recovery stations
• Construction of a tank on pillars of 500 m3 and height 16 m
