This water park is only the culmination of the Ollainville water treatment plant known as the Moulin Neuf, on a former industrial site that had been cleaned up and rehabilitated which had replaced the old mill. The site is next to the Syndicat de l'Orge, de la Rémarde et de la Prédecelle, which does everything in its power to ensure that the paths and routes in the Barley basin are practicable and maintained.

It is one of the many Orge retention basins between Breuillet (Port Sud basin), Egly (Trévoix mill basin), Brétigny (Petit Paris and Carouge basins) and Longpont-sur-Orge (Parc de Lormoy) and beyond. These pools, very well maintained and offering exceptional flora and fauna, make it possible to make loops of more than twenty kilometers quite easily (as long as one remains in the valley). A set of exotic and relaxing pools.
