About Us

The best technology to preserve your water resources

We are a subsidiary of the Veolia group and the leading specialist in water treatment. Our teams design and deliver drinking water or wastewater treatment plants as well as smaller standardized water treatment equipment for industrial or municipal customers. We also offer a range of services (audit, maintenance, digital, etc.) to cover all water treatment plant management needs.

Solutions for a sustainable world

We create technologies for sustainable development. Our expertise is deliberately focused on preserving the environment: we help you reduce your carbon footprint and optimize your water consumption, in particular through our zero liquid discharge (ZLD) offer, which aims to reuse wastewater after treatment within the plant. We also offer you methanization solutions to exploit the energy produced by the sludge from your plant's water treatment. The biogas generated in this way can be consumed within the plant, in a nearby plant or in the municipality's distribution network. We provided this for Artois Methanisation with our colleagues from Veolia subsidiary Sede. Our objective is to help you preserve water and energy resources. 

We are a global player: our standardized technologies are designed globally to meet the standards of different countries and our services are designed locally to be as close as possible to your needs and above all to be as responsive as possible according to your needs or emergencies. Even in extreme emergencies:  this is the challenge we faced when Hurricane Irma hit the islands of Saint-Barthélémy and Saint-Martin in 2017, where our teams from Sidem and Veolia Water Technologies Spain did everything possible to restore water production and distribution on these islands as quickly as possible. 

We are developing access to water for more and more people, while preserving it for future generations. With its 11 million inhabitants and drinking water needs that will double by 2030, the city of Dhaka in Bangladesh is in need of a new water treatment plant; we will design this plant, which will produce 500,000 m3 of water per day.

Our expertise at your service

Our global presence and our 170 years of experience are unique in the world and allow us to base our technologies on years of practice and innovation to best serve our customers. We are constantly evolving to meet your needs, whether in after-sales services or product innovation. 

Water treatment plants are part of the circular economy. Municipalities and businesses alike wish to preserve the environment as much as possible, with just one plant or several plants located worldwide. Thanks to an international presence, with 9,000 employees working all over the world, we can help you achieve your objectives of optimizing the management of natural resources for all your plants, wherever they may be. A current example of this is our work with Danone.

We have designed our offers to meet each stage of the water cycle and to meet any demand for water treatment: process water, drinking water, wastewater, desalination, on land, at sea,... Our objective is to help you preserve your environment, wherever your plant is based, while delivering the water quality you need.

Being competitive while preserving water resources is possible

Our solutions and technologies are designed to make you more competitive: reducing your operating costs, strengthening your company's social responsibility and ensuring the efficient management of your installations, in particular thanks to our Hubgrade digital offer. To meet your needs as quickly as possible, we have also developed a range of standardized products and are constantly working on the development of new offers to adapt to changing needs and long-term development.

Our innovative wastewater and sludge treatment technologies also maximize your energy production and allow you to recover certain products to give them a second life, so you can extract raw materials and take advantage of valuable by-products.

You can count on us for your daily requirements (maintenance, ordering chemical reagents, etc.) as well as for urgent requests:  a Mobile Water Services mobile unit can be on-site in under 24 hours to temporarily replace defective equipment. 

We are at your service to find the best solutions for:

  • Drinking water and industrial water.
  • Wastewater treatment and reuse.
  • Energy production and recovery.
