French environmental services provider Suez has secured contracts to operate the wastewater networks and the wastewater treatment plants for Nantes Métropole.
Suez stated that the two contracts are for seven years and are worth €87m in total revenues.
The company has committed to enhance the underground facilities, under the terms of the contract, which extend upto 1800km in wastewater networks and infrastructure. The contract also includes the use of new solutions to optimise the management of the service.
These services include smart cleaning of the networks to help conserve the facilities and to prevent operating incidents.
The company will also partner with local start-up Quai des Apps, to develop augmented reality-based apps for assisted maintenance.
The second contract includes the operation of the city’s 19 wastewater treatment plants. The Nantes city authorities have renewed the company, which has operated two wastewater treatment plants.
Suez will use its ‘NOSE’ and ‘NOSE City’ solutions to forecast and control the olfactory footprint of the facilities in real time.
It will reinject biogas of up to 10GWh/year in the Petite Californie wastewater treatment plant. It will deploy smart energy management tools at the two wastewater treatment plants, with a goal of reducing energy consumption by 15%. It will also execute a pilot project on future positive energy wastewater treatment plant.
Suez Group Senior Executive vice president in charge of France, Italy and Central Europe Marie-Ange Debon said: “Suez is proud of Nantes Métropole’s renewed confidence in the Group and its employees. In order to support the community in choosing its strategic orientations, SUEZ will put all its innovative capacity at the service of the territory and its inhabitants to contribute to the sustainable transformation of the Metropolis.”
In November, the company was selected by Hauts-de-Seine Departmental Council in France. The contract will benefit 1.6 million inhabitants and is considered to be the largest of its kind in covering wastewater network operation in the entire Île-de-France region.
The contract has two main objectives. One is to control the discharge during wet weather and to manage stormwater in urban areas. It will come into force from next January.
