NEW PUMPING STATION, ALLEGHENY CITY, PA.

THE new pumping station for Allegheny City, Pa., which is illustrated elsewhere in this number, is being built at Montrose, a small village on the Allegheny river, some nine miles above the city and at a point where the natural conditions of the river and the absence of any village or habitation of importance for many miles above the source of supply, should render the water as pure as it is possible to get it in its natural state. Besides the selection of a site at a point where drinkable water could be obtained in abundance and at all times, the great intake pipe terminates on the river end in a crib of timbers some 2,700 feet long, inclosing rocks and gravel, and sunk to a depth of five feet below the actual bed of the river, which at this point is composed of coarse sand and gravel. The shore end runs into great settling tanks, placed in the pumproom of the new buildings, from whence it is pumped into the mains for distribution. The city councils have under advisement the use of sand filtration on an extensive scale, which it is expected will ultimately be adopted, and,taken into consideration with the arrangements already made, should give fo Allegheny City an abundance and purity of water unexcelled by any city of the world.

建筑包含水泵和锅炉的回答e designed by Mr. Wm. Ross Proctor and Mr. T. E. Billquist, architects, and suggest, as far as it is possible, in work of this class' the renaissance of Italy. They are to be built of buffcolored brick and terra cotta of a lighter shade set' upon a base of buff Ohio sand stone, with a roof constructed of iron trusses covered with slates. The plan briefly consists of three distinct buildings, rectangular in form and placed with their longitudinal axes parallel to one another. The building facing the river is the pumphouse, 210 feet in length, 71 feet in depth, and 60 feet from the floor to the underside of the ridge. Directly in the rear of this is the machine shop, 105 feet in length and 41 feet in depth, arid immediately in the rear of this isThe boiler house, 130 feet in length and 50 feet in depth. 1 he pumphouse is arranged to contain ultimately six pump ing engines, five of which will be installed as soon as the building is in condition to receive them, having a capacity of 12,000,006 gallons per day of twenty-four hours. There will be a light iron gallery running around the entire pumphouse at a height of 20 feet above the floor, accessible by circular iron stair cases in each corner of the room and from which the entire plant can be overlooked. At the level of the cornice, some 44 feet above the floor, will be placed an electric traveling crane of 30 tons capacity for use in setting and replacing or repairing the pumps.
