Veolia, a water management, waste management and energy services company, has announced France’s first unit for reusing treated wastewater to produce drinking water.
Veolia inaugurated the unit with Vendée Eau, a French water utility company.
This solution will provide an additional resource of 1.5 million m3 (396 million gallons) of drinking water over the period from May to October, during periods of increased water shortage in the Vendée.
"The reuse of wastewater to produce drinking water is the fruit of the collective ambition of a number of committed local authorities, and represents a real advantage in terms of competitiveness and attractiveness for these areas. It provides a proven and sustainable response to the increasing scarcity of water resources," said Jean-François Nogrette, Director of the France and Special Waste Europe zone.
The development of alternative water sources, such as the reuse of treated wastewater, is part of a range of solutions for dealing with the increasingly frequent droughts in France. Using this resource to produce drinking water, as is the case in several countries around the world, can be an effective response, particularly in coastal areas that are subject to recurrent water stress, are densely populated and have high tourist flows.
Veolia helped to design and implement a refining unit that will initially (from 2023 to 2026) reuse 1.5 million m3, out of the city's 4.5 million m3 of wastewater. This capacity will then be gradually increased to reuse between 2 and 3 million m3 of wastewater by 2027, equivalent to the consumption of 60,000 inhabitants.
In five stages, the unit removes particulate pollution, bacteria, viruses and micropollutants such as pesticides and drug residues to produce quality drinking water.
Veolia has employed its patented technology based on ultrafiltration and low-pressure reverse osmosis (Barrel). This solution contains 200 membrane elements as well as an ultraviolet disinfection and chlorination process.
"A national first, the Jourdain program is the country's flagship project, demonstrating that France has the technologies and the commitment at the local level to move ahead and to address the challenges posed by climate change. Its launch complements and reinforces the importance of the Water Plan's ambition to increase wastewater reuse from 1% to 10% in 5 years," said Estelle Brachlianoff, Veolia's Chief Executive Officer. "Here we are concretely inventing the drinking water service of the future: a service of excellence, at the cutting edge of innovation, capable of responding to one of the greatest challenges in today's water world: that of scarcity."
