Veolia to operate Le Mans Métropole's wastewater treatment plant

Veolia  has been chosen by Le Mans Métropole, an urban community of 19 municipalities in France, to operate its wastewater treatment plant at La Chauvinière in 2018.

Veolia will operate the plant for nine  years.

Several innovations will be developed on the La Chauvinière location, allowing it to cut down energy consumption and become part of a more circular model.

The firm will install a process that will transform the CO2 arising from the purification of biomethane into sodium bicarbonate. The CO2  will then be used by the neighbouring household waste to energy unit.

It will also focus on the extraction of phosphorus, a product that is demand in agriculture, as part of an R&D phase on the site.

An integrated pilot Hypervision 360° facility with digital technologies, will gather all the treatment plant data and optimise its operation.

In real time, Le Mans Métropole will be able to remotely monitor performance indicators.

Veolia will also build an anaerobic digestion unit that will generate biogas from the La Chauvinière sewage sludge.

Veolia CEO of Water in France Frédéric Van Heems said: "Working alongside Le Mans, we will make the La Chauvinière plant a real reference in the water treatment sector.This plant illustrates what tomorrow’s plants will be like, that is, firmly committed to the circular economy, benefiting from excellent service in the forefront of innovation, and delivering remarkable performance."
