20/03/2017 - 2014-2017: completion of Ganay retention basin

A basin to protect Calanques National Park

Between 2014 and 2017, SERAMM, SUEZ’s subsidiary, has built a retention basin upstream from the Géolide wastewater treatment plant and buried under Ganay stadium. The facility, which has a storage capacity of 50,000 m3,improves the metropolitan area’s wastewater treatment system by enabling it to treat wastewater and stormwater during periods of heavy rainfall. With an investment of 50 million euros by the SUEZ group, the basin, which required three years in construction, will undergo tests for six months before becoming operational in autumn 2017.
