Davies, H.L., 1961. Geological report on the surface penstock route and the No 2 power station site, Port Moresby hydroelectric scheme. Record  1961/081. Bureau of Mineral Resources, Geology and Geophysics, Canberra.

Abstract

Water is to be conveyed from the projected Sogeri Dam, about half a mile above Rouna Falls, to the projected Power Station No.2 at the foot of the falls. One proposal is that a low-pressure penstock should be laid from the dam to a surge tank near the head of the falls, and a high-pressure penstock conveys the water from this point to the power station. The rocks are volcanic agglomerate, a few tuffs, and basal conglomerate, all part of the Astrolabe Agglomerate. They are flat-lying and undisturbed, except for jointing and one instance of minor shearing. The agglomerate and conglomerate are generally competent, but the tuff which marks the conglomerate-agglomerate transition is probably weak and incompetent. Investigation has centred on the high-pressure penstock route and power station site, and has involved outcrop mapping and seventeen diamond drill holes. The main problem on the penstock route is the upper scree slope, where boulders and rubble are up to thirty feet deep. The best route appears to be a direct one from near peg T8 over hole P5 to the power station. Power station foundations appear to be sound. Alternative routes for the low-pressure penstock are at present being investigated. Three or four shallow diamond drill holes will be needed at a later date.
