2011 NEwS, HIGHLIGHTS

Human resources policySuccessful launch of the first employee shareholding plan: “Sharing”

More than 76,000 employees of SUEZ ENVIRONNEMENT in 19 countries were offered the chance to purchase SUEZ ENVIRONNEMENT shares on preferential terms. With an uptake of close to 25%, the operation demonstrates the commitment of SUEZ ENVIRONNEMENT’s employees and the values we share.

DiversityThe Maison pour rebondir, an example of the Group’s commitment to diversity

The “Maison pour rebondir” opened its doors in Bordeaux in late 2011. This multi-partner structure specializes in

the integration of people who have difficulty accessing employment. It is open to everybody and provides an innovative approach to employment and the development of the regions in which the Group operates.

R&D and innovationInternational cooperation agreement with GE (General Electric): from a commercial relationship to a strategic and cooperative relationship

SUEZ ENVIRONNEMENT and GE signed a non- exclusive international cooperation agreement for two years in R&D and innovation, to develop new technological solutions for flow mana- gement, in response to rising demand from megalopolises worldwide.

AgbarInnovating to stand out

Agbar has launched the Aqualogy brand, which brings together Group expertise with a focus on three areas: environmental and operational technologies, management solutions and technologies for transferring know-how.

waste recoverywhen waste becomes a source of electricity and heat

SITA NEWS has put ReEnergy, one of the most modern energy recovery plants in Europe, into operation. The plant processes the waste of more than 1.9 million people a year, and generates 256,000 MWh of electricity. ReEnergy also provides heat to greenhouses located near the plant, saving around 3.5 million m³ of natural gas.

SITA UK and Lend Lease have signed a 25-year contract with the South Tyne and Wear Waste Partnership for revenue of EUR 825 million. The contract entails the management of 190,000 tonnes of residual household waste a year and includes the design, construction, financing and operation of an energy recovery unit with capacity of 256,000 tonnes a year.

TO PERFORM WELL, WE HAVE TO BE OPEN AND CO-CONSTRUCT WITH OUR PARTNERS AT ALL LEVELS OF OUR BUSINESS.

Crisis managementUrgent action against a new micropollutant

During the summer of 2011, Lyonnaise des Eaux and CIRSEE, in partnership with the Bordeaux Regional Agency for Health and the Urban Community, set up an unprece- dented action plan to tackle a completely new micropollutant in water: ammonium perchlorate.

New contractual modelsA new model for water in France, the Contract for water Health

Lyonnaise des Eaux has reinvented its partnership with local authorities on the basis of three pillars: overhauling governance, developing the economic model and strengthening innovation to respond to the challenges associated with water. Within this framework, Grand Dijon and Lyonnaise des Eaux have confirmed water

and sanitation services contracts for Dijon/ Plombières-lès-Dijon and Talant until 2021. The Tarbes authorities have awarded a 20-year sanitation services management contract to Lyonnaise des Eaux worth EUR 80 million. Lastly, for the first time in France, the Charter for Local Water Governance, signed between the Laon authorities and Lyonnaise des Eaux, launched a new guidance process for water and sanitation services contracts.

Access to waterAlgiers contract renewed

In 2005, SUEZ ENVIRONNEMENT and the Algerian government launched a new partnership: the management contract. As well as establishing targets for service quality and a continuous drinking water supply, SUEZ ENVIRONNEMENT undertook to transfer its know-how to local staff. Six years later, these targets have been achieved, and the government has confirmed its confidence in SUEZ ENVIRONNEMENT by renewing the contract to support the upgrade of water and sanitation services for the city of Algiers. The contract represents EUR 105 million over five years. It includes the progres- sive extension of moder-nization and access to water services in the Algerian province of Tipaza, with a target of 24-hour access to drinking water.

GovernanceInnovative public-private partnerships in Australia

Degrémont, in partnership with Transfield Services, has won a contract to operate and maintain water and sanitation services to the 1.1 million residents of the city of Adelaide. This “Alliance” contract, worth EUR 840 million over 10 years, is commercially innovative since governance is led by the public water company and private operators. The Group and its partner will manage the entire water cycle.

Degrémont and Transfield Services have also won another Alliance contract to operate and main- tain drinking water production and sanitation facilities in Perth, for a total revenue of EUR 294 million. The contract will come into effect in July 2012 for a 10-year term. Its aim is to enhance environmental performance and the services provided to residents, improve water of excellent quality and protect water, which is a precious resource for future generations in Western Australia.

Openness and cooperation Industrial partnerships

In France, SITA has won, with ROS ROCA, its first contract to design and build a pneumatic house- hold waste collection system in Vitry-sur-Seine, and will launch, with the city of Courbevoie, as a national exclusive, the circulation of the first, new-generation 100% electric household waste collection vehicle.

Lyonnaise des Eaux, a subsidiary of SUEZ ENVIRONNEMENT, and Terrena, the leading French agricultural cooperative, have just created the first company exclusively dedicated to the water and environ- mental needs and issues of farmers. The aim is to come up with new approaches and think of new solutions together, to respond to the challenges associated with water and natural resources in France (e.g. reusing wastewater to irrigate crops).

Commercial successes US

United Water has been awarded contracts in Poughkeepsie (New York) and Pontiac (Michigan). In Pontiac, the company has signed a water and sanitation service contract for a revenue of EUR 28 million over five years. United Water will be responsible for opera- ting and maintaining the drinking water distribution network (30,000 m3/day for about 70,000 residents) as well as rainwater and wastewater networks (100,000 m3 a day).

The operator’s targets include: creating savings of USD 2.8 million a year by optimizing the facility’s operations, improving the drinking water bill and reducing water losses on the network.

Middle East

In Qatar, Degrémont has won the contract to extend a wastewater treatment and recycling plant in Doha West, for EUR 35 million. The project will increase the plant’s capacity from 135,000 m3/day to 175,000 m3/day, to serve approximately 650,000 people. In Bahrain, Degrémont completed construction of the Al Dur desalination plant.

This plant, which uses reverse osmosis, will be the largest desalination facility in the Middle East, with drinking water production capacity of 220,000 m3/day.

Asia

In China, SUEZ ENVIRONNEMENT has won the contract for an effluent treatment plant at the Wuhan indus- trial chemicals park. The contract provides for long-term capacity of 60,000 m3/day for the wastewater treatment plant, and the construc- tion from 2013 of a water production plant with long-term capacity of 300,000 m3/day.
