« We have just received the 170 km of pipes that will enable us to provide 100,000 rural people with drinking water in the KOULIKORO Region (Mali) », states Thierry BARBOTTE, General Director for VERGNET HYDRO. Funded by the German bank KREDITANSTALT FÜR WIEDERAUFBAU (KfW) and led by the Malian NATIONAL AGENCY FOR HYDRAULICS (DIRECTION NATIONALE DE L’HYDRAULIQUE) and the German company GAUFF CONSULTANTS (the technical coordinator), this project is carried out by a joint-venture gathering VERGNET HYDRO and the Malian companies MTCS and ATC MALI. They are committed to installing 269 water points in 20 localities, fed by solar-powered pumps.
« VERGNET HYDRO wrote the initial technical studies and has provided the equipment (pipes, pumping systems, taps and chlorination system), ATC MALI is providing the 20 water towers and MTCS handles all the construction works », specifies Najib BENAZOUZ, Business Manager for VERGNET HYDRO. The project budget, divided over 2 lots of 10 localities each, amounts to 5.5 million euros (3.6 billion CFA francs).
First inaugurations planned for the end of 2018
« This is a 100%-solar project. But, this is also a 100%-treatment project. All pumped water is treated by chlorination before being stored in the water towers and drawn by the villagers », adds Thomas CANDELORO, Projects Manager for VERGNET HYDRO. Indeed, a crucial part of the project consists of constructing buildings next to the water towers which will house the chlorine production (electrolysis process) and injection processes. Furthermore, 5 of the localities will be equipped with power generators.
This 12-month long project started in February 2018. The first inaugurations are planned for the end of 2018. « We have a lot on our plate but we are going to respect the deadlines, because our joint-venture is well organised. Actually, we had already constructed 11 equivalent hydraulic centers in Mali together with MTCS and ATC MALI, back in 2011 », concludes Thierry BARBOTTE.
