“The site known as Markley Farm is a point where the water of the Ohio River is deep and free from drainage or any other vitiating influence to affect its quality, perhaps for a century to come, if ever. The shore is bold, and, with the bed of the river, is of gravel and rock formation, washed clean by an active current at all seasons of the year. Pumping works may be located at this point without any objectionable and expensive inlet-pipe; while the adjacent hills afford an excellent site for a storage reservoir, 307 feet above extreme low water, and 75 feet above the Garden of Eden Reservoir. On the lower level there is a fine plateau for locating, not only the pumping house, but subsiding reservoirs and filtering basins.

“The force-main extending from the pump house to the storage reservoir will be short, or about 1,450 feet long, whereas, works located on the second site, or any other sites examined, would require force mains several thousand feet in length. By the first site, water from the river would be lifted by the pumps and forced to the reservoir with the least amount of power, friction, and expense of fuel to do the work. This site also commands an excellent and safe landing for boats supplying the works with coal.

“The analyses of waters lately taken at the Water-Works and at the Markley Farm clearly indicate the superior quality, purity, and healthfulness of the latter.

“It has been suggested that the offal from one or more distilleries, said to be in operation at New Richmond, some ten miles above the Markley Farm, would leave its taint in the water reaching the latter point. My answer is, that in this case the river, so slightly affected at New Richmond, and flowing ten miles to reach the Markley Farm, would, from agitation and dilution, and from the well-known self-purifying property of water, become pure.”

Regarding the other sites surveyed he said:

“The second, but objectionable, site for water-works was found some three miles above the Garden of Eden reservoir, and about the same distance below the mouth and offensive discharge of the Little Miami River. This location, although favorable in many respects, intercepts the drainage of the upper portion of the city, and all of that from the Miami Valley emptied into the Ohio River, which renders that site wholly inadmissible for water-works purposes.

“The valley of the Miami forms a water-shed of several hundred square miles in area. Upon the surface of this vast plain is deposited the dead carcasses of animals, and the droppings from cattle of all kinds. The ground is covered with decayed vegetable matter, and the soaking of stable-yards, hog-pens, slaughter-houses, distilleries, stagnant pools, etc. The refuse is washed off by rain storms into the Miami, which is the common receptacle, and thence into the Ohio River.

“It is only necessary, first, to disease the water, then disease the man; and it is clear, therefore, that water-works located below the Miami would, by wholesale pollution, disease the whole community.

“There is no city in the civilized world so regardless of the cleanliness and health of its citizens as to adopt a plan of water supply to foist upon them the concentrated filth from sewerage and the impurities of a stream, the water of which is only fit for mill-power, manufacturing purposes, and for cattle to drink; and I did not think that Cincinnati was emulous of setting the example.

“With regard to intermediate points between the county line and the mouth of the Little Miami River, I found the Ohio River lined with sand-bars, some of which projected from the shore nearly to the middle of the river, miles in length; while the bottom or bed of the river was, for the most part, covered with logs and craggy stones.”

His plan embraced the construction of pumping works for raising the water, first, from the river into subsiding and filter reservoirs, and then pumping it a second time into storage reservoirs. The water was to flow, through 10⅓ miles of 42-inch supply mains, into Eden Reservoir. The capacity of the pumps was estimated at 60 millions daily. The recapitulation of cost was:

For Engine-House and Grounds $312,790.00
For Pumping Engines 750,000.00
For Force Mains 92,130.00
For Storage Reservoirs 521,529.45
For Subsiding Reservoirs 560,252.00
For Clear-Water Well 14,669.60
For principal Supply Main, two lines 1,811,078.00
Miscellaneous expenses 60,500.00
————— 4,131,949.05
Add ten per cent 413,194.90
—————
Total cost $4,545,143.95

In conclusion, he said:

“I, therefore, regard the first and best site, known as the Markley Farm, as one commanding all the advantages sought, where works may be erected combining greater simplicity of construction, economy of cost, and maintenance when put in operation, than could be built at any of the other points mentioned.”

No. 7.
MOORE’S SURVEY.

On the 23d of January, 1882, Mr. A. G. Moore, Superintendent of the Cincinnati Water-Works, submitted a communication to the Board of Public Works relative to the present condition of the pumping works and its future requirements. From it we arrange the following:

“The present pumps are deficient; that during the summer of 1881 the daily demands exceeded, at times, their capacity; and on one particular day there was a deficiency of over six million gallons. The engines are generally of light construction, and not sufficient for any increased loads. They are expensive in operation and maintenance. First-class engines of to-day would save two-thirds of the fuel used. The principal reliance, during the summer, is the large “Shield” engine, which is most extravagant on fuel, and has a wrought-iron force-main, of weak material, intrenched 35 feet below the surface of the street. Some of the boilers are of an age that require them to be treated with the greatest care, and should be condemned. The principal buildings do not afford protection or access to the pumps in case of derangement during average high water. The hill-top service is inadequate, and a larger and more comprehensive system should be adopted for the supply of the increasing territory.

“The subject of increasing capacity requires immediate attention; and should the removal of the works be deemed inadvisable, it will become essential to at once proceed with the erection of machinery, buildings, aqueduct, and aqua-fort at the old works. The cost of these improvements is placed at $1,394,000; reserve engine for 1884, $618,000; and sewer in Front Street, to carry the sewage below the works, $1,600,000. Total, $3,612,000.”

His plan for Markley Farm provides for one lift of 305 feet, with three compound pumping engines of 100 million capacity, subsiding and storage reservoirs, and one effluent-main 62 inches in diameter.

The estimate is condensed as follows:

Aqua-fort and buildings $410,000.00
Engines and boilers for 100 million capacity 1,255,000.00
Three subsiding reservoirs of earth and masonry embankments, with 90 acres of water surface } 1,836,500.00
Effluent-main, including 55,000 feet of 62-inch pipe, from the Farm to Eden Reservoir, and 18,000 feet of 48-inch, from Eden Reservoir to Harrison Avenue } 1,804,000.00
Contingencies 460,000.00
—————
Total $5,725,000.00

The important question is presented by him, which the public must decide, namely, whether it is a prudent policy to expend four millions of dollars to improve the old works, and retain all the expensive and unreliable machinery, and still supply an impure and turbid water; or to expend an additional two millions for an entire new system, from a source where a supply of pure and clear water can be secured, commensurate with the growing city.

He also embodies, by way of comparison, the following estimate for locating the works on the Kentucky side of the river:

For right of way and property, State and municipal 500,000
Aqua-fort and buildings 410,000
Three engines, with boilers complete 1,255,000
Subsiding Reservoirs 1,836,000
Effluent-mains, 23,000 feet 533,000
Tunnel for pumping main 270,000
Tunnel under the Ohio River, 3,000 feet 825,000
Thirty-inch main to Eastern Avenue, 22,500 feet 201,000
Contingencies 550,000

Total for Newport plan $6,381,000
