Thrifty water point to make your children love washing their hands

Sommaire

lavage des mains, eau, hygiène

Introduction

This tiny water point entirely made of recuperation materials allows children to wash their hands in the most thrifty, self-directed and hygienic way.

Instead of turning on the tap and using a lot of water, your child will lift a lever with his/her own wrists and use a water trickle, just enough to wet her/his hands and rince them.

Inspiration : This system was freely inspired by the "CANACLA", made with clay in Dakar (http://canacla.com/blog/?page_id=115).

The word "Canari" in western Africa names a traditional vessel made of clay. Jacques Vanhercke used one of those traditional container to invent the "Canacla" (For "Canari" plus "Clapet", which means "valve" in french). It's indeed because of a valve and of a thin hose which simply goes through the wall of the canari that the water gently flows out the Canacla, right when your wrists open the valve by lifting up the lever (Therefore : Your hands don't touch anything !)

Interest by this concept, we thought about an easy to make solution, that our 3 years old son could also use on his own. Though we built this system with wastes gathered around our neighbourhood (plastic bottles, wooden boxes, battens, etc.). We replaced the valve with a crimped hose to make the whole system even easier to build.

What can I use it for ?

This water point can be installed in your bathroom, if it doesn't have a sink, or in your kitchen (mounted on the wall).

It can also be used outside, in a garden and also during local events, like a school fête for example. It can then be hung to a tree or a streetlight with straps. Its height can then easiliy be adjusted to the one of children.

Matériaux

1 wooden box

1 plastic bottle

1 wooden batten

1 small wooden plank (6x8 cm - 2,37x3,15 inch)

1 piece of iron wire

1 thin silicone tube (ex : baby nose cleaner, breast pump ...)

1 elastic

1 big nail (7 to 8 cm - 2,75 to 3,14 inch)

A few screws

1 staple

Outils

Hammer, screwdriver, drill, wood saw, cutter

Étape 1 - Lever's completion

Gather 3 transversal battens from the wooden box (1 short / 2 long) et use them to make a T-shaped lever (around 25cm - 10 inch long). Attach those 3 pieces with some glue.

Étape 2 - Anchoring the nail

Block the nail between the heads of the 2 screws and let the tip of the nail stick out a bit (don't forget to file the tip of the nail)

Glue / screw the small wooden plank on the batten (at the level of the bottom quarter)

Étape 3 - Lever positioning

• Retrieve a corner of the wooden box and glue/screw it on the batten, over the small plank.

• Position the level on the top leaving the space of a child's hand. Mark and drill 2 small holes in the lever at the height of the nail.
• Screw the lever on the corner of the wooden box and insert the iron wire in the holes. Twist the ends of the iron wire around the nail. (NB: The iron wire must be tensed).

Étape 4 - Mise en place du tuyau et de la bouteille

• Découper le fonds de la bouteille. Percer son bouchon à un diamètre un peu inférieur au tuyau. Insérer le tuyau en force et le laisser dépasser d'1 cm dans la bouteille.
• Positionner la bouteille sur la latte, au dessus du levier. Ajuster la longueur du tuyau.
• Fixer la bouteille avec 2 fils de fer, tenus par 4 vis.
• Faire passer le tuyau sous le clou et le maintenir sur la tranche de la planche avec une agrafe. Mettre l'élastique en place (autour du clou et de la vis) et régler sa tension pour que le tuyau soit pincé.

Étape 5 - Finitions

Selon l'endroit où on souhaite installer le point d'eau, on peut ajouter un récipient (cuvette, seau ou saladier...) muni d'un tuyau en guise de "lavabo". On peut également recueillir l'eau sale dans un seau pour arroser des plantes ou nettoyer des toilettes sèches (dans notre cas).

Il est aussi possible d'"habiller" le petit point d'eau afin de cacher les bouteilles et de le rendre ainsi esthétique. Un "coffrage" en cagette sera facile à faire et assez joli.
