This shower prototype have been realized with Jonathan Benabed, auto-constructor o f his tiny-house
This system is largely inspired by the recycling shower project of Jason Selvarajan.
"A few figures:
"The recycling shower:
The objective of this shower prototype is to divide by 7 the water consumption of a shower without impacting the comfort of the user who want to stay under hot water for a while.
It is currently in the test phase in order to know its real environmental and economic impact. Indeed, depending on the purchase of new or second-hand equipment, the realization of this shower can very quickly become too expensive for real profitability (not to mention the ecological cost of new equipment).
In our case, we bought a maximum of second-hand equipment for a total cost of 150€.
According to the ShowerloopCalculator, this type of recycling shower is cost effective in less than a year of operation for a 4-person home.
The pictures presented come from a demonstration prototype, without housing integration for a better visibility of the system. However, it's relatively simple to adapt to a classic shower. Great care must be taken to ensure that the connections are watertight.
Principle of operation:
The principle of the recycling shower is to be able to fill a water tank of about 10L located under the shower tray.
When the user use the water from the shower to relax and enjoy, he can operate a valve to shut off the water supply to pump, filtrate, reheat and supply the shower head with water of the tank.
Estimates suggest a 7-fold reduction in the consumption of a conventional shower.
Any contribution that simplifies the system is welcome.
Sanitary Aspect:

Il est possible d'ajouter une lampe UV assurant l'élimination de potentiels pathogènes.
En comparant l'usage de la douche à un bain où l'usager reste dans son eau, nous avons fait le choix de ne pas installer de lampe UV à la vue du coût que cela peut représenter. Nous n'avons pour le moment pas fait de test sanitaire révélant la pertinence ou non de l'utilité d'une telle lampe.
Remarque:
La réserve est à installer sous le bac de douche. Selon les disponibilités de chacun:
A l'aide de flexible femelle/femelle:

Remarques:
Remarque:
Ceci est une utilisation possible. D'autres tests sont à effectuer comme l'utilisation du recyclage avec de l'eau bien savonneuse ou encore l'utilisation de la réserve pour plusieurs douches.
