普韦布洛的山水供应
科罗拉多州普韦布洛,决心给国民ns an abundant supply of pure and wholesome water, has availed itself of that furnished by the Pueblo Water Supply and Power company. This system has just been completed after several years’ work and at great cost. The source is what is termed the underflow of the Fountain river and is practically inexhaustible. The company has installed two intake-pipes or galleries, by means of which this water is collected. One, the smaller of the two, is 1,500 ft. long. The present flow is more than sufficient to supply not only the North Side, but the whole of Pueblo. The pipe carries an average of 19,000,000 gal. in twenty-four hours, the amount specified by the contract that may be called for at any moment, if the emergency arises. The amount needed at present is not more than 6,000,000 gal. in twentyfour hours, and this is exceeded by 13.000,000 in that space of time. The second intake-pipe is 4,000 ft. long, and through it comes twice as much as through the first gallery. The company can thus obtain nearly 60.000.000 gal. in twenty-four hours. Provision has been made for building a third gallery—something that will not be needed in the lifetime of this generation. A double concrete reservoir has been built two miles north of Pueblo. Its capacity is 25,000,000 gal., and that quantity of water will be kept constantly in storage in case of emergency, while for the ordinary supply the water will flow into the mains direct from the source. These reservoirs are of concrete reinforced with steel netting, and each is equiped with pipes by means of which they can obtain water from the main line running between them. The water can be shut off or turned on with the greatest ease, and there is no danger of any hitch in operation or a breakdown that would cut off the supply. From the reservoir the main pipe-line runs in a general northerly direction to the source of supply far up the Fountain river. The intake-pipes are fifteen miles from Pueblo. The pipe-line is constructed of metal pipes riveted together. The pipes are laid underground at varying depths, but always deep enough to secure the purity of the flow and coolness. . Where the line crosses arroyos, solid concrete foundations have been laid on bedrock, in which the pipes are laid. This insures the impossibility of a break in the line, such as might occur during a big flood in one of the arroyos. if proper precautions w^ere not taken. Two miles from the source of supply a large concrete well has been sunk, where the water is turned into the ’main for the city or is turned into a waste-pipe leading back to the Fountain river. For many months the company has been discharging many thousands of gallons of water daily, all of it going back into the river. At the outlet into the river the water flows out in a stream of nearly 30-in. diameter, which, of course, will not be of the same volume when the full supply is turned on in Pueblo. The gathering well is a large concrete basin, sunk 30 ft. in the ground. To this well the intake-pipes converge, and the water is turned into the main for the city supply. These intake-pipes, or galleries are of concrete, with their joints uncemented, which leaves space for the water, seeping through the gravel, to find an entrance into the pipe as it flows to the gathering well. The intake-pipes are laid many feet beneath the bed of the river, where the underflow is pure and clear. No surface-water is turned into the pipes. In fact, it would be impossible to turn the surface-water into the mains unless special provisions were made. Work, financed by Philadelphia and other capitalists, was started on the undertaking in October, 1905, and has been carried on continuously ever since. The plant will be operated very cheaply, as no pumping will be required. The cost of the water to the consumers will, therefore, be very little.
