From the project

Ensemble de systèmes pour l'arrosage du jardin

Le but du système de remplissage automatique des OYAs est de pouvoir s'absenter pendant les vacances tout en laissant les OYAs se gérer tous seuls.

Les OYAs sont des sortes de pots en argile enterrés utilisés depuis des millénaires pour distribuer de l'eau à des cultures.

On remplit régulièrement ces pots. Grâce à leur porosité, l'eau se diffuse à travers l'OYAs au fur et à mesure où les racines des plantes assèchent la terre à proximité.
