The sites for a proposed pumping station and pipeline were examined on 28th October, together with Mr W. Moore, Resident Engineer, Southern District, Engineering and Water Supply Department. The examination followed a request from the Engineer-in-Chief, dated 22nd October. The proposed works include a pumping station located a few feet above lake level, on a bench excavated into weathered limestone, and a pipeline and haulage-way passing from the station up to an access road about 140 feet above it. The succession of rock types at the site and the geological history of the area have been described by Johnson.
