Preserving water

Visit of Gérard, Chairman and CEO of GDF SUEZ, to employees of SHEM, at Laruns, October 4, 2011.

In addition to the expertise developed by SUEZ ENVIRONNEMENT, GDF SUEZ represents a major force in promoting the sustainable management of water resources. It has, in particular, embraced the CEO Water Mandate, a UN Global Compact initiative which brings together companies committed to joint efforts for water management. Like all the signatories of the CEO Water Mandate, GDF SUEZ is committed to:

  • increasing the operational efficiency in terms of water management,
  • working with suppliers to improve their water management as well as the quality of the residual water treated,
  • working in partnership with stakeholders to resolve problems in the sustainable management of water resources,
  • reporting progress made completely transparently.

Urban water recovery in Mexico

To better manage water resources in the City of San Luis Potosi, the local authorities decided to recover its treated urban wastewater, and use it to supply the Federal Electricity Commission (CFE) power plant.

This process, set up by Degrémont Mexico for the power plant‘s cooling towers, saves 21,600 m3/day of drinking water.

Before the San Luis Potosi wastewater treatment plant was commissioned in 2006, the entire region’s wastewater flowed into the Tenorio Lagoon. The lack of treatment had polluted the site heavily, decimating the fauna. Five years after commissioning the wastewater treatment plant, the local fauna had taken over the site again.

Storengy is engaged in preserving water resources

As part of the process to extract gas from underground reservoirs in the water table, some of the groundwater is recovered in large volumes at certain sites. Storengy has put in place a project aimed at treating this water at its four most productive sites, to release it into the natural environment.

In 2010, regulatory studies and outlet analyses were conducted in collaboration with the companies Safège and Ondeo IS, subsidiaries of SUEZ ENVIRONNEMENT. The project is ongoing, with research, start on site and administrative procedures to launch the new facilities in 2013. The facilities will be able to recover large volumes of water (10,000 m3 per year).

Reducing air pollution

Apart from greenhouse gases, other industrial emissions into the atmosphere can also significantly impact the environment. These include pollutants such as NOx, SO2, and VOCs (Volatile Organic Compounds). These pollutants impact health.

The year 2010 marked a major change in European air pollution regulations. The new Industrial Emissions Directive was issued to take effect at the beginning of 2011.

The IED replaces and merges seven previous directives. It will become the consolidated directive of reference for industrial air pollution. It impacts the GDF SUEZ Group’s facilities and those of its industrial customers. It will be transposed into the national laws of the EU Member States on legally set timelines, by early 2013 at the latest.

GDF SUEZ is committed to implementing the best techniques available at its various power production and incineration sites to reduce these emissions as much as possible.
