TEXTThese works are situated in the north-east part of the city, at the corner of High Street and Rotten Row, near the Cathedral. The ground occupied is triangular in shape, and has been divided into two, forming a low-level and a high-level yard, one being 16 feet higher than the other. Between them is a retaining wall, varying in thickness from 2 to 6 feet. The main flue from the boilers passes through and along the back of the wall to the chimney shaft at the south-west boundary of the station; the shaft is 150 feet in height from the bottom of the flue, 14.5 feet square at bottom, and 7.5 feet across the flats of the octagonal part at top. The main buildings are of the castellated Scottish baronial style of architecture, and comprise engine-house, accumulator towers, boiler-house, workshops, store, offices, and space for workmen's dwellings; these take up the greater part of the lower yard adjoining High Street. The coal store and water-storage tanks, for supplying the water to the main pumps and condensers, form the roof of the boiler-house, and are on the same level as the upper yard; the entrance to the coal store and upper yard is from Rotten Row. The upper yard will be used for the storage of pipes.

The buildings have been designed for containing six sets of pumping engines and eight boilers, only half of which have at present been put in. The engines are of the marine type, inverted, direct- acting, triple-expansion, surface-condensing, and steam-jacketed. The cylinders are 15, 22, and 36 inches diameter, with 2 feet stroke. The three main pumps on each engine are single-acting, with rams 4.5 inches diameter and 2 feet stroke, and are driven direct from the engine cross-heads. The fly-wheel weighs about two tons. The condenser has a cooling surface of 530 square feet; and the quantity of water required for condensing is about equal to the quantity discharged through the power mains. Each engine pumps 150,000 gallons of water in 10 hours against a pressure of 1,120 lbs. per square inch, with steam of 150 lbs. per square inch. The boilers are Lancashire, made of mild-steel plates, 30 feet long and 7 feet diameter, with two flues 2.75 feet diameter in each. They are fitted with Vicars' mechanical stokers, to which the fuel is conveyed from the coal store above by means of steel-tube shoots. A Watmun automatic water-circulator is connected to each boiler; and Green's economisers for feed-water are placed in the main flue.

The boilers were tested to 250 lbs. per square inch with hydraulic pressure, the working pressure being 150 lbs. per square inch. The stokers and economiser-scrapers are worked from shafting overhead, which can be driven either by a three-cylinder hydraulic-engine or by a small steam donkey-pump engine fixed in the boiler house. There is also provided a three-cylinder hydraulic engine to drive the machinery in the workshops, a 20-cwt. movable hydraulic crane on rails, for handling pipes in the upper yard, and a 20-cwt. direct-acting hydraulic lift from the lower to the upper yard. There are two accumulators, having cast-iron cylinders and rams 18 inches diameter and 23 feet stroke, with base plates 7 feet diameter and weight cases 14 feet outside diameter by 22 feet deep, suspended from the crossheads on the top of the rams by strong steel sling-bolts. The accumulators are loaded with iron-stone slag to give a pressure of 1,120 lbs. per square inch, the minimum pressure guaranteed being 1,000 lbs. per square inch.

As at present arranged, about ten miles of piping will be laid to supply the central part of the City between High Street on the east, Cranstonhill on the west, Sauchiehall Street on the north, and the north side of the river Clyde on the south. About six miles of pipes have already been laid and put under pressure. Although not complete, the works were formerly inaugurated by the Lord Provost, Magistrates, and Members of the Town Council on 30th May 1895. A number of machines are already connected, and applications have been made for supply to others. The works were designed by Messrs. Ellington and Woodall, London, and carried out under the superintendence of Mr. James M. Gale, Engineer to the Water Commissioners.
