In Egypt, SUEZ wins an operation and maintenance contract for one of the largest wastewater treatment plants in Africa

SUEZ and its partner, Arab Contractors, win the operation and maintenance contract for the Gabal El Asfar1 wastewater treatment plant in Cairo, for four years and an overall amount of €40 million, of which €28 million will be attributed to SUEZ. With a capacity of 1 million m³ per day, the two treatment lines of the facility will treat wastewater for almost 5 million inhabitants of the city of Cairo, Egypt. The contract will come into effect as of March 1st, 2021.

Greater Cairo has seen a historic growth in population for several years, and currently has a population of 22 million inhabitants. To meet the growing needs of the urban agglomeration in terms of wastewater treatment, the Gabal El Asfar plant in Cairo has undergone two extensions since its construction to become the largest wastewater treatment plant in Africa. This new contract, which follows the construction and operation of one of the lines starting in 2005, enables to continue the transfer of expertise from the Group’s Egyptian teams.


The contract includes the operation and maintenance of both treatment lines with total capacity of 500,000 m³ per day each, as well as the rehabilitation of the plant’s supervision and power generation systems. SUEZ will also carry out optimization works to enable the plant to increase its energy self-sufficiency from 55% to more than 65% with the production of electricity from the biogas generated by the treatment of sludge. The electricity2 produced will avoid the emission of 28,000 tons of carbon equivalent per year, thereby contributing to the reduction of the facility’s carbon footprint.
