Excavating Penstock Ditch
Constructing the Gariuai Mini Hydroelectric Power Project was done using local manual labour, with few exceptions. Here an excavator was required in order to advance the penstock (high pressure water pipes) through a small hill, as the risk for avalances was too big for manual digging.
