NOTES AND CLIPPINGS.
The Coolgardie Water-supply.—But for the discovery of paying gold in the Coolgardie district, it is almost needless to say that no such costly a scheme could have been financially possible. The gold was discovered in 1892. In 1893 the gold rush set in, and as the railway only negotiated 235 out of the total 363 miles from the sea to the mining center across a then practically all but waterless desert, the amount of hardship incurred can more easily be .surmised than detailed, the average rainfall inland being but 7.14 inches and the evaporation 82.6 per cent. The collectable rainfall is barely 114 inches, and the summer shade temperature frequently exceeds 100° Fahrenheit. The water collected in soaks and native wells was wont to sell at. half a crown a gallon in 1893, and when later the shafts of the mines reached water: it proved to be impregnated with salt. , This salt water when evaporated and
condensed commanded a price of £3 10s. per 1,000 gallons. The pamphlet before us states that the brine carried the enormous proportion of 30 ounces of saline matter to the gallon, i, e., 30/160 = 18% per cent., whereas normal sea water carries only 2% per cent. In 1894 the railway reached Coolgardie and Kalgoorlie, and such were the difficulties about water that its supply cost the railway in summer £1,000 a day. By the end of 1895 the production of the fields surpassed1 230,000 ounces of gold yearly. Several vague projects and applications for a monopolistic concession to supply water were brought forward, and by July, 1896, the government decided to itself undertake the business on a scheme outlined by its gifted and lamented chiefengineer, Mr. C. Y. O’Connor, who had already made a marvelous success—in the teeth of much adverse professional criticism —of important harbor-works on an exceedingly novel design. Mr. O’Connor’s first instructions for the Coolgardie waterworks. contemplated a supply of but one million gallons per 24 hours, a quantity it was subsequently decided, after discussion, to enhance as far as 5,600,000 gallons, say 3,500 cubic feet. The estimate was put at £2,500,000, something like three years’ gross out-turn from the gold fields, and this sum only covered the main supply without the distributary piping in the various towns to be served. In September, 1896, the premier, Sir John Forrest, introduced a bill for raising the requisite funds which, after
a storm of opposition—not wholly, we fear, disinterested or aboveboard—was ultimately passed.
Investigations occupied the best part of two years, and the original Money Bill, introduced in September, 1896, was followed up by the specific Goldfields Construction Bill, passed in September, 1898.
As executed, the work consists of a 30- inch pipe-line divided up into eight sections in its total length of some 330 miles from the collecting reservoir at the Helena River weir to the Tooran Hill service-reservoir above Coolgardie. The Helena reservoir on the Darling range, where there is an ample rainfall, is within 30 miles of the sea; its crest stands at 420 feet, and its lowest offtake at 340 feet above sea level. The collecting reservoir appears to be ir itself a quite notable work with its concrete dam over 100 feet high, its gathering ground,, which can be largely increased if so required, of 850,000 acres, and its capacity of 4,600 million gallons, say 736 million cubic feet. The full level of the terminal distributing reservoir being 1,540 feet, the actual lift is but 1,200 feet, although including friction and fall to offtakes it is calculated to equate 2,700 feet.
The pipes for this enormous length of line are all, as already said, 30 inches diameter. They are made of steel plate in lengths of about 28 feet, and except where the pressure is exceptionally high, they are uniformly % inch thick. The width of two plates constitutes the circumference of the
