Pipe lines.-The estimated cost of a 10-inch cast-iron water main, which is proposed for the line from Melville to Coddington Point, based on the use of class 150 centrifugally cast pipe, is $3.37 per linear foot. Distribution mains. It is understood that the main between Coddington Point and the naval training station on Coasters Harbor Island is in place. The estimated cost of a main from Coddington Point to the Naval Hospital is $15,000 and from the hospital through the city of Newport to connect with the existing line under the harbor to Goat Island is $15,000; total, $30,000. The details of the estimates of cost of filtered water, delivered at Newport, are based on the use of 11,000,000 gallons per month, or 132,000,000 gallons a year, and are as follows: (h) Scheme "A."-Eighty million gallon reservoir on stream at Melville and pipe line via highway to Coddington Point. Operating cost per year, interest on $645,000 at 4 per cent.. Depreciation, $645,000 at 2 per cent... Maintenance....... Pumping. Filtration Total. Cost per 1,000 gallons, 39.2 cents. (i) Scheme "B."-Eighty million gallon reservoir on stream at Melville, pipe line via railroad with gravity flow to Coddington Point. (4) Scheme "C."-Eighty-million-gallon reservoir at Lagoon at Melville, pipe line via either railroad or highway, pumping plant at Melville, filtration plant at Coddington Point.

(k) Scheme "D."-Ten-million-gallon reservoir on Melville, pipe line via railroad for gravity flow to Coddington Point and 70,000,000-gallon reservoir and filtration plant at Coddington Point. Depreciation, $585,000 at 2 per cent.. Plant cost..

NAVY DEPARTMENT, Washington, December 4, 1926. SIR: The act making appropriations for the naval service for the fiscal year ending June 30, 1927, contains the following provision: That the Secretary of the Navy shall have prepared plans and estimates of cost of the remaining three fleet submarines heretofore authorized but not appropriated for, each to have the highest practicable speed and greatest desirable radius of action, such plans and estimates to be in readiness for submission to Congress on the first day of the next regular session, and the appropriations herein made on account of "Increase of the Navy" shall be available, in the discretion of the Secretary of the Navy, for the employment of such additional draftsmen and other technical employees as may be required for the preparation of such plans and estimates, in addition to the regular forces of the bureaus concerned elsewhere provided for in this act. In accordance therewith general plans have been prepared of two types of fleet submarine, one of the mine-laying type and one of the cruiser type. It is estimated that these submarines will cost on account of hull, machinery, and outfit, $5,750,000; on account of armament for the mine-laying type, $850,000; and on account of armament for the cruiser type, $1,020,000. In the event the construction of these vessels is undertaken, it is the department's present intention to build two of the three remaining submarines of the mine-laying type and one of the cruiser type, a division which, with those fleet submarines now under construction, will provide a group of three vessels of each type. Sincerely yours, The Hon. NICHOLAS LONGWORTH, CURTIS D. WILBUR, Speaker of the House of Representatives. |
