THAT QUEEN LANE RESERVOIR AGAIN.
IT seems more than doubtful whether Philadelphia will ever see the end of its trouble with the notorious and costly Queen Lane reservoir, which, even after all the expensive tinkering to which it has been subjected ever since it was built, is again leaking—some accounts say—at the rate of 20,000 or 36,000 gallons a day. The exact location of the leak has not yet been found. It was at first thought that it was in one part of the big embankment which helps to contain the 112,000,000 gallons of water, and an expert diver went down into twenty-six feet of water and plugged up the mouth of the twelve inch drain pipe which runs to the massive stop-cock chamber—it being supposed that the leak was in the drain. The day after this had been done it was found not only that the leakage had not been stopped but that it had actually increased, and when the diver again descended to examine the drain, it was found that the plug was securely fastened in it. The twelve-inch pipe was then opened inside the chamber and found to be clear of water. Then the conclusion was reached that the embankment or stone masonry of the chamber was leaking. To discover from which side of the chamber the leak is coming, experiments will he made by boring holes in its asphalt and concrete pavement. The calculations are that the side in which the holes first fill up with water will indicate the side of the leak. Twenty-six feet of water is registered in the north basin, in which the leak has been discovered. This is only four feet less than the normal standard. This vast body of water will, however, have to be run off to allow the necessary repairs to he made. So far as regards its system of water supply, Philadelphia certainly offers an object lesson to those who insist that every municipality should own its own water works system.
