Throughout the year, the Maison de l’Eau presents to the public large aquariums with fish from the local Huisne and Sarthe rivers. The ecosystem includes trout, bream and barbel. This old water mill built in 1906, also allows visitors to browse the history of water treatment and how drinking water is obtained. Many of its old fittings are still in use for visitors to see such as the 8.5 diameter wheel and steam engine. In 2007, a Bollée wind turbine was restored and reinstalled near the entrance.
