Installed in 2020 on the Beaurade wastewater treatment plant (360,000 inhabitant equivalent), the Purecontrol solution reduced the site's energy consumption by 15%. Following this initial success, the solution was deployed on 7 other treatment stations in Rennes Métropole. The Metropolis is now confirming its innovation and resilience approach by choosing Purecontrol for the next 4 years, with a contract for the widespread deployment of all of the city's sanitation infrastructures (treatment plants, lifting stations, lifting stations, photovoltaic panels, etc.).
