For example, in the Katuiti home, much of the water for daily use for this family of 15 comes from rainwater. They replaced their original roofing material (palm fronds and screwpine leaves) with grooved boards in order to steer rainwater into a gutter in the eaves and from there by pipes to two cisterns.
舉例而言，Katuiti 家的主屋斜屋頂由原本的椰葉、林投葉改鋪成波浪板，以利雨水收集，再從屋簷的水管引進地上兩座圓墩墩的儲水桶，這就是一家 15 口日常飲用水的來源。
