Wastewater reuse

We implement solutions for wastewater treatment and reuse in many parts of the world. The aim? Ensure people have access to this essential resource.

Freshwater accounts for only 2.5% of the world's available water. With the rapid increase in the world's population, accelerating urbanization and global warming, this resource is becoming scarcer. Today, access to drinking water is a major environmental, social and economic challenge for cities and industries.

Water stress: A global issue

Many regions of the world are subject to water stress. The reuse of wastewater is an unavoidable solution in these areas subject to social and health risks, a drop in agricultural yields, reduced industrial productivity, conflicts of use, fires and desertification.

Treated wastewater is an abundant resource. Reusing wastewater is cheaper than producing desalinated water or transporting drinking water over long distances. There are standards for wastewater reuse, strictly regulated by law, at the global level (WHO), at the level of the European Union, for example, and at the national level.

Treated wastewater can be reused for agricultural irrigation (which alone accounts for 32% of the global market), landscape irrigation (20%), industry (19%) and even groundwater recharge (2% of the global market) - source: GWI 2010. It can also be treated to drinking water standard in certain regions of the world.

Australia

Reduce a building’s drinking water consumption by 92%

Since 2011, we have been collecting rainwater and recycling wastewater in a closed loop at the Darling Quarter, one of the greenest buildings in the world. As a result, we provide 68% of the 8-storey building's water needs for air conditioning and watering the landscaped areas.

Recycling wastewater in an artificial lake

We installed a wastewater treatment plant to provide closed-loop water recycling from an artificial lake located near the Burj Khalifa Tower in Dubai. The plant uses our Actiflo Pack clarification solution to treat 62,400 m3/day of water, i.e., 2,600 m3/hour.

Wastewater recycling for agriculture and industry in Hawaii

In Honolulu, Hawaii, we treat nearly 50 million liters of secondary effluent from the city and county each day to produce nearly 45 million liters of recycled water for industrial applications (power generation, oil refining, etc.) and irrigation.

Windhoek

Namibia

Domestic wastewater used to secure drinking water supply in Windhoek

Namibia is the driest country in Southern Africa. In Windhoek, the capital, we produce drinking water from domestic wastewater. We are able to cover almost 35% of the city's needs and help combat the region’s chronic water shortages. In total, we produce 21,000 m3 of water per day and supply more than 400,000 people with drinking water.
