sump. This arrangement proved entirely successful and, by the end of the year, the cutting of the tongue had been completed and the depositing of fine cement concrete in it had been begun.
The two large masonry culverts, each 12 feet wide by 10 feet high, provided for carrying off storm-water whilst the foundations of the main dam were in course of construction, were completed in March. They came into operation on completion of the cofferdams in March. No very heavy falls of rain occurred during the year though the total quantity of rain which fell was well above the average. The culverts proved in consequence to be of ample size. At one time, after a thunderstorm, the water rose in them for a brief period to a height of 8 feet but this was partly due to the fact that the outlet end was obstructed by some centering.
Concrete work in the dam-trench between the culverts and the stream-bed was proceeded with and was carried to a height of about 40 feet above Ordnance Datum though the confined space available for working in necessarily made progress slow.
In all, 18,700 cubic yards of soft material and 5,900 cubic yards of rock were excavated during the year, 10,350 cubic yards of soft material and 2,800 cubic yards of rock being from the stream-bed foundations. The quantities of cement concrete deposited and of granite masonry set were as follows:-
Fine cement concrete, 3,092 cub. yds. Hearting concrete containing granite dis-placers, 3,907 Granite ashlar, 17,217 ft. 19The remaining consignments of 18" cast iron pipes and specials, totalling 1,604 tons, for the suction mains and two additional rising mains, were received early in the year and a Contract for laying them was let to Messrs. Sang Lee & Co. on 6th March. Good progress had been made by the end of the year, 4,000 lineal yards of main having been laid whilst 2,100 lineal yards of pipes were distributed along the road in readiness for laying in the trench.
A Contract was let to Messrs. Sang Lee & Co. in June for the construction of the pump-pit required in connection with the pumping machinery which is on order and on the completion of this work a further Contract was let to the same firm in September for the construction of the massive concrete foundations to support the pumping engines.
The first consignment of pumping machinery was due in November but, owing to delays resulting from the war, it had not arrived up to the end of the year.
