SHISHIODOSHI

Shishi-odoshi is a Japanese device made to scare away birds and beasts damaging agriculture. It is a type of Sozu water fountain that is used in Japenese gardens. IT consists of a segmented tube, usually of bamboo, pivoted to one side of its balance point. At rest, its heavier end is down and resting against a rock. A trickle of water into the upper end of the tube accumulates and eventually moves the tube‘s centre of gravity past the pivot, causing the tube to rotate and dump out the water. The heavier end then falls back agains the rock, making a sharp sound, and the cycle repeats. This noise is intended to startle any herbivores which may be grazing on the plants in the garden.

Avignon-Clouet Architects adapted this idea and applied it to rainwater harvesting in their house, Shishiodoshi House, built in Reze, France in 2010. In compliance with local urban planning regulations, the eaves of the rood remain within the boundaries of the property, and channel rainwater towards a vast Shishiodoshi built of aluminum. This authentic Japanese rocking founting system sets itself in motion as soon as the first drizzle starts falling and winds up in the final stretch with the water collecting tank.
