The Complete Plant of a Thriving Western City.

Specially written for FIRE AND WATER ENGINEERING.

Delaware, a flourishing city of Delaware county, has a population of about 8,000. It manufactures woolen goods, agricultural implements, chairs, iron fences, carriages, and cigars. It is situated nearly in the geographical centre of the State, and is the home of the Ohio Wesleyan University. In the city are four steam railroads, and it is becoming an important electric railroad centre. No less than five of these are completed or under construction, some of them connecting through lines between Cleveland and Cincinnati. The city has a fine electric light, heat, and power plant, which furnishes a large portion of the business centre and adjacent resident sections with heat through a hot water heating system, which is one of the most elaborate and successful built, heating hotels, public buildings, and residences at a less cost than coal. Natural gas has recently been introduced on nearly all of the streets; it is supplied at twenty-five cents per 1,000 feet, and is being generally used and much appreciat ed by the citizens. This city is also noted for its sulphur springs and mineral waters, which are largely use, and are very beneficial for rheumatism and diseases of the stomach and liver. The Delaware Water company, a corporation, was organised and the works were designed and built by Moffett, Hodgkins & Clarke, engineers, of Watertown, N. Y. They were put into operation on November 1, 1899. The system has now about twenty-one miles of mains (four-inch to sixteen-inch), with 235 fire hydrants and about 1,100 services, and supplies over 5,000 people, besides three railroads, electric light plant, college buildings, and ice plant. The water is obtained three miles north of the city from gravel beds on the bank of the Olentangy river; the pumping station and engineer’s residence are built of brick, with slate roof, and equipped with two seventy-five-horsepower horizontal tubular boilers, two compound, duplex Deane pumps of 2,000,000 gallons capacity each in twenty-four hours, an Ingersol-Sergeant air-compressor, twelve-inch steam cylinder and fourteen-inch stroke, hot water heaters, feed-pumps, and injectors—all in firstclass condition. The water supply consisted originally of a circular well bricK lined, twenty-five feet in diameter and twenty-five feet deep, with its walls resting on rock which has been excavated five feet. From this well a gallery was built parallel with the river bank by excavating a trench to the rock, building the side walls of loose masonry, and covering with stone slabs, making a filter gallery four feet wide, six feet high, and 293 feet long, from which is a fourteen-inch intake pipe to the river for use in cases of a large fire or other emergency. In 1896, as the gravel supply did not yield sufficient water, a well was drilled in the rock, near the large receiving well, to a depth of 255 feet, and a natural flow of excellent water was obtained.


I bis is largely increased by the application of air from the compressor, delivering under sixty pounds perssure a solid six-inch stream. During the past winter another eight-inch well was put down 250 feet from the first, and is even better than the six inch. This well is also connected to the air-compressor ; it delivers an eight-inch stream when under pressure, and has a fine natural flow. The water is delivered from the pumps through a sixteen inch pipe to the standpipe (twenty feet by 100 feet) located on an elevation near the pumping station and forty-five feet above the pumps. A line of sixteeninch pipe extends from the standpipe to the centre of the city, always furnishing an excellent pressure of fifty to seventy-five pounds, which can he increased to 150 by closing a valve at the standpipe, and giving direct pressure. The pumps are usually started at 4:30 to 5 a. m., and run at about eighteen-stroke per minute until 10 o’clocck, when the standpipe is nearly full; then at a moderate speed until 2:30 to 3 p. in., when the the fires are hanked. At 3 o’clock they are again started and run in the same manner to 7 or 8 p. m., as the demand requires, leaving the standpipe full after streetsprinkling and heavy demands are over for the night. This stand_____ serve will supply the demands until time for s_____g in the morning, unless a large fire occurs, in which case the pumps are started. Mr. W. S. Green has been engineer for over eight years, and fully understands every part of his work; he is assisted by one man as fireman. The quality of the water supplied is excellent, always clear and cool, and is highly indorsed by the physicians of the city, who say they never have had a case of typhoid that could in any way be traced to this water; it has also the approval of the State board of health. About forty-five per cent, of the 1,100 services are supplied by meters placed on the larger, such as railroads, electric light, college buildings, hotels, saloons, livery stables, etc. Five streetsprinkler wagons are in service a portion of the season, taking, when in service, from 50,01×1 to 150,000 gallons per day; the railroads averaging about 2,000,000 gallons per month. The average number of gallons pumped per day for the months of April, May, and June was 504,600. Deducting the amount used for railroads, streetsprinkling, and a _____ew of the manufacturing plants, and the average per capita consumption is about sixty gallons per day. Col. C. W. Wiles, secretary and treasurer of the company, has been in charge of the plant since April, 1892. He has seen it grow from less than 300 services to its present condition. Since he assumed charge, he has added over five miles of mains, and thoroughly understands every part of its physical condition. Every building and piece of machinery is kept well painted and in excellent repair; every leak is promptly looked after; and the plant is one of the best in this country. F. M. Marriott, president of the company, has been a life-long resident of Delaware, and is senior member of the law firm oi Marriott, Freshwater & Wickham. He is largely interested in telephone, waterpower, and lead properties in the South and West. Henry C. Hodgkins, C. E., of Syracuse, N. Y., was the original constructing engineer, when the works were built. He has since been the consulting engineer of the company. Many of the excellent features and the careful construction of the plant were due to his judgment. Mr. D. R. Smith, assistant superintendent, has for fifteen years been engaged in gas and waterworks construction, and is an efficient and capable man for the place.
