SUEZ is a French environmental services group that designs and operates drinking water, wastewater and waste treatment infrastructure for municipalities and industry. Its registered office is at Altiplano, 4 place de la Pyramide in Puteaux, in the western Paris business district, and it trades as SUEZ Societe Anonyme, RCS Nanterre 901 644 989. The group reports 40,000 employees in 40 countries and describes more than 160 years of continuous operation in these services.
Ownership and structure
SUEZ has been privately held since a consortium completed its acquisition of the group on 31 January 2022, ending its separate stock-exchange listing. Shareholders including Meridiam, Global Infrastructure Partners and the Caisse des Depots group with CNP Assurances injected further capital in November 2022 to fund follow-on purchases such as SUEZ Waste UK, IWS and EnviroServ. Xavier Girre is chief executive. The group is organised around water and waste activities, with France and the United Kingdom as its largest markets and a growing share of revenue from international operations and hazardous waste.
Two divisions matter most for industrial customers. The water business builds and runs treatment plants, desalination facilities and industrial water circuits, including process and cooling water for refineries and petrochemical complexes, while the waste business handles collection, sorting, hazardous waste storage and energy-from-waste plants.
Water operations at scale
- In 2025 SUEZ supplied drinking water to 67 million people and sanitation services to 36 million people worldwide.
- The group has designed and built more than 260 desalination plants; construction of a 66,500 cubic metre per day seawater reverse osmosis plant in Metro Iloilo in the Philippines began in April 2025 with JEMCO and Metro Pacific Water, on a 24-month schedule.
- In India, SUEZ won a 25-year, EUR 456 million contract in Salem, Tamil Nadu, its largest drinking water production and distribution award, serving more than one million people.
- In Hong Kong it took a sludge dewatering contract for the Sha Tin sewage treatment works, one of Asia's largest cavern-based wastewater facilities.
- In France it signed a 15-year contract to run drinking water and wastewater services for the Herault Mediterranee urban community.
Waste, hazardous waste and energy recovery
SUEZ is the largest operator of energy-from-waste facilities in France measured by authorised annual capacity, and it generated 8.7 TWh of energy from waste and wastewater in 2025. Hazardous waste is one of the two segments the group has chosen for selective expansion. In Italy it acquired Gruppo Ecosistem, an integration the company reports as ahead of plan after double-digit growth in the segment in the first half of 2026. A prefectural authorisation in September 2025 extended the life of the Villeparisis hazardous waste storage facility in the Ile-de-France region by 20 years and increased the group's final hazardous waste disposal capacity in France by 30 per cent. Waste handling extends to sorting and recovery: in 2026 SUEZ signed a 12-year, EUR 420 million contract to build and operate three waste sorting and recovery facilities at Calce near Perpignan.
Contract backlog and recent awards
The order backlog reached a record EUR 3 billion in the first half of 2026. The largest single award was a EUR 2 billion, 15-year contract in Oman to provide drinking water and wastewater services to 2.3 million people, or 43 per cent of the country's population, which the group describes as its biggest contract in the Middle East. In the United Kingdom, SUEZ signed a EUR 460 million, 10-year contract to operate the Milton Keynes City Council energy recovery facility, a longstanding customer, and took over operation of the Ness energy-from-waste plant in Aberdeen. It also renewed or extended contracts in Devon, South Gloucestershire and Doncaster. In France, a EUR 465 million, 10-year contract covers rebuilding and operating the Romainville-Bobigny municipal waste treatment centre. In March 2026 SUEZ International SAS sold about 4 per cent of the Italian utility Acea through an accelerated placement, raising roughly EUR 196 million.
Financial performance and funding
Group revenue was EUR 9.5 billion in 2025, up 3.6 per cent, with EBITDA of EUR 1.5 billion, down 1.5 per cent on energy price effects and difficult French market conditions. Net debt stood at EUR 5.8 billion at the end of 2025 with EUR 2.2 billion of available liquidity. First-half 2026 revenue rose 3.2 per cent to EUR 4.743 billion and EBITDA 7.6 per cent to EUR 781 million, helped by international growth, hazardous waste and a transformation programme that cut general and administrative costs by 5.8 per cent. Net debt was EUR 5.9 billion at 30 June 2026. The group issued a EUR 600 million 10-year green bond in June 2026 with a 4.00 per cent coupon, nearly 3.7 times oversubscribed, extending average debt maturity to 6.5 years, and renewed a EUR 750 million revolving credit facility for seven years.
Innovation, safety and reporting
SUEZ ran its transformation under the banner Safety, Solutions, Success and set out a Sustainability Roadmap 2030 covering decarbonisation, nature and social commitments, alongside a second sustainability report prepared under the EU corporate sustainability reporting directive. In 2025 the group was the only environmental services company in the French intellectual property institute INPI top 50 for patent filings, for the second consecutive year. External assessments in 2025 gave SUEZ 78 out of 100 from EcoVadis, a BBB rating from MSCI and a Sustainalytics score of 15.9. Current innovation work includes optimising anaerobic digestion of food waste for biogas, safe treatment of nitrous oxide canisters and wastewater reuse systems.
