THE NEW WORKS AT CINCINNATI
The water commissioners of Cincinnati have sent in a detailed statement of the work now being done at California, from which it appears that the new water system will be completed by the end of 1907. The source of the water is the deepest portion of the Ohio river opposite California, by means of a stone intake pier attached to the Kentucky shore. It will pass down a shaft and brick-lined 17-ft. tunnel and 1.430 ft. long to a shaft on the Ohio shore, where will be four 30,000,000-gal. triple-expansion pumping engines in a pump?pit, MS ft. deep, the boilers, etc., will he in a house with annex, and the water will !>c delivered to the settling reservoirs on the elevated ground, where will also be the electric generating and other machinery, etc., to operate the valves and machinery in,and round the filtration plant. A large steel coal building for the storage of about 7,oo:> tons of coal is provided immediately in the rear of the boiler house. From this station two cast-iron 60 in. water mains, each 4,000 ft. long, will convey the water in two settling reservoirs, with an aggregate capacity of 3b5.000.000. From these mains branch-mains 60-in. in diameter, will convey the water to the distributing chambers, thence to three coagulating basins when necessary. From the settling reservoirs the water will be delivered from near the surface through two cast-iron 60-in. mains, from each reservoir to distributing chamber in the headhouse of the tiitration plant. From this pumping station the water will be delivered into the present low and intermediate service districts by a cast iron main along Easton avenue and Third street to a junction with the present water mains delivering water from the Front street station to Eden Park reservoirs. From this junction the line will continue as a 48-in. main along Third street ar.d Eggleston avenue to Ninth street, and thence west on Ninth street to Cutter, and along Wade, Western avenue. McLean and Spring Grove avenues to Queen City avenue, diminishing gradually to 36-iti. at the la’ter point; then extending west on Queen City avenue as a 30-.11. main to the Western Hills pumping station located on Queen City avenue, near Rankin street. The water from the hilltops will he delivered from the main pumping station through a 48-in. main from the pumping station up the hill to Columbia avenue, thence ‘along Columbia and Humbolt avenues to Woodbttrn avenue, where the 48in. main is divided into two 36-in mains, one running southwardly and connecting with tlie 36-in. main in McMillan street, the other running northwardly and dividing into several branches at Madison road. To supply tlie higher elevations of Price Hill, Fairmount and the territory west therefrom, a pumping station on Queen City avenue—the Western Hill stationis being erected, and will he used to supply both Price Mill and Fairmount direct. Provisions are made at this station for the installation of machinery which will deliver water direct to the still higher elevations of Westwood and the territory northwest therefrom. To give an equal distribution of water throughout the various districts of tlie city, especially in the elevated territory, larger supply mains have been planted to be laid along the most suitable route to distant sections of the elevated territory. From this headhouse the water is to he passed through 84-in. steel mains to each or all of three coagulating basins, two of which have a capacity of lo.ooxouc gals., and tlie third a capacity of 2.000. coo-gals. In passing from the headhouse the water will he charged with the solution of lime and iron to facilitate the classifications of the water while passing through the coagulating basins, and to supply .a film for the filterbeds. 1 he water will be drawn from the opposite side of tlie coagulating basins and passed through an 84-in. steel main to a valve-chamber, whence two 60-in. cast-iron mains, will convey the water through a pipe-gallery to either of twenty-eight covered filterbeds, each with a capacity of 4.000.000 gals, per day. From these filters the water is conveyed through two 60-in. cast-iron mains to a clear water reservoir of nominally 18.000,030-gals, capacity. From it the water will flow into a shaft adjacent down to a 7-ft.. brick-lined tunnel, running at an average depth of alxv.it 130 ft. beneath the surface through the rock formation, and in almost direct line from that shaft to a similar shaft in the rear of the main I his tunnel is 22.250 feet in length between the shafs. This pumping station consists of a mail building containing the pumping engies for th delivery of water to the territory now being sup
plied by what is known as the low and intermediate-service, as well as-dhat required for supplying the high-service or 1⅛.elevated territory in the city. In the rear of’the main building is located the boilerhouse, in the rear, of which are two steel coal-storage buildings, with a capacity of about 7,000 tons. The gross ratio pumping capacity of the new waterworks at the river, when finished, will be 120,000,000 gals, per day; of the filtration plant, 112,000,000 gals.; at the main pumping station, 110,000,000 gals., of which 75,000,000 gals, per day will be for the intermediate-service and 36,000,000 ofr the highservice. The gross rated capacity of the western hills pumping station for Price Hill and Fairmount will be 5,000,000 gals, per day. The combined capacity of the settling reservoirs will be 365,000,000 gals.; of two of the coagulating basins, 10,00c,000; of the smaller basins, 2,000,000; ;md of the clear water reservoirs, 13.000,000 gals. 1 he capacity of the tunnel and various pipe-lines connecting these parts arc fully up to, and in some instances exceed these daily capacities.
GEOROE H. HEN’ZEN HERO, C. E.,
under whose care and supervision these waterworks are being constructed, is well known on 1 oth sides as a consulting and hydraulic engmee. of th? highest repute, for many years he held the responsible position of chief engineer of the water department of Milwaukee. Wis., and siiue that time has been engaged in the practice of his profession. IIis fame is so great that he has been overwhelmed with calls to act as consulting engineer in a large number of important cities in the United States, and his name is connected with the construction and improvement of waterwo: ks systems all over the United States. Ilis crowning achievement will be the work he is doing at incinnati, where he has reduced chaos to order and so arranged the whole system as to guarantee its completion before very long and the establishment of a waterworks plant that shall have few, if any rivals in the world.
