SUEZ worked alongside the National Dams and Transfer Agency on one the largest national hydraulic projects: construction, development and operation of the Sidi Lahdjel drinking water production plant. As the second largest such site in Algeria, it supplies several cities in including Mostagenem, Arsem, Oran (MAO) and their regions.
Within a short time, SUEZ was able to develop a water treatment line to deliver high throughput, and implement efficient installations at all phases
Upstream of the Sidi Lahdjel plant, raw water from the Cheliff dam is subject to specific treatment at a de-sludging plant designed by SUEZ teams. 820,800 m3 /day are then aerated
, clarified and filtered prior to final disinfection. SUEZ equipped the Sidi Lahdjel plant with innovative processes, in particular Densadeg® 2D clarifiers (high settling rate, water quality) and 18 Aquazur® V sand filters each with a surface area of 151.4 m2.
