Gariuai Intake Ponds Under Construction
The intake ponds in Garuiuai are progressing rapidly. These two ponds are collecting water from the springs in Builai and Wainalale.
The construction done now is of a small earth fill dam at each spring. This will create a small pool in order to raise the water level sufficiently for collecting the water into the penstock (the pipe to the power station about 187 metres below). A concrete base containing technical parts, including the intake connecting to the penstock, is more or less finished. The rest of the dams are made by compacted soil with a core of ironwood. The dams are sealed with geotextile, with stone pitched surface.
