Cascade de la Carrière Misery (Nantes, Pays de la Loire, France) - Man-made Waterfalls on Waymarking.com

[FR] Cascade artificielle située dans l'ancienne carrière Misery à Nantes.
Pour que la magie prenne, un système de grosses canalisations (que la végétation devrait petit à petit recouvrir) a été installé et caché le long des parois rocheuses. Dans le bassin (de 500 m3 environ), un performant système hydraulique et de pompage envoie l’eau vers les trois déversoirs, comme pour une fontaine classique. C’est un automate électronique, caché dans une station située à l’entrée du parc, qui joue les chefs d’orchestre. De là est aussi actionnée la fonction brumisation sur l’étang.
La cascade fonctionne en circuit fermé. L’eau retombe dans un bassin parfaitement étanche donc il n’y a aucune perte, sauf celle liée à l’évaporation. Elle est éteinte le soir, mais est poussée à fond le week-end pour les nombreux promeneurs.
[EN] [FR] Artificial waterfall located in the former Misery quarry in Nantes.
For the magic to take hold, a system of large pipes (which the vegetation should gradually cover) was installed and hidden along the rock walls. In the basin (around 500 m3), an efficient hydraulic and pumping system sends water to the three weirs, as for a traditional fountain. It’s an electronic machine, hidden in a station at the entrance to the park, that plays the conductors. From there is also activated the misting function on the pond.
The cascade operates in a closed circuit. The water falls back into a perfectly watertight basin so there is no loss, except that linked to evaporation. It is extinct in the evening, but is pushed fully at the weekend for the many walkers.
