NEW YORK AUXILIARY HIGH-PRESSURE SYSTEM.

NEW YORK AUXILIARY HIGH-PRESSURE SYSTEM.

According to Commissioner J. H. O’Brien of the department of water supply, gas and electricity, the auxiliary high-pressure system for fireservice will be completely finished and in working order by the end of the year at latest. Of the 270,000 ft. of main called for, 205,000 have been laid and of the 1,270 hydrants needed 830 have been set. Of the mains already laid those embtaced in the district extending from Twentythird street to Waverlcy place and from the North river to Broadway, and consisting of about 100.000 ft. of main and 200 hydrants of the most approved modern type have been temporarily connected with the Croton system and are available as a low-pressure system in advance of the completion of the high-pressure fire stations. The work on the pumping stations at Oliver and South streets and at Gansevoort and West streets is likewise progressing favorably. The engine foundations, which are the most difluult part, have been completed, and the brick work of the building is now going up, so that it is expected that these stations will be ready for use by the end of the year. The work under the contract for motors and pumps is well advanced. The electrical machinery is finished and ready to be shipped. The pumps are assembled and will shortly be ready for shipment, as well as the piping, valves, etc. Work under the contracts for the salt-water intakes at the Gansevoort street station and at the Oliver street station is under way, and this work will also he finished by the end of the year, although by no means essential, even if it were not completed, to the operation of the system, and it is expected that the system will be ready for service by the end of the year. Bids for supplying and maintaining apparatus and supplying the electrical power required for the high-pressure fire service will be opened on the 15th ittst. (tomorrow). For reasons of its own the Edison company did not lid on this contract when it was first advertised. The contract for the telephone system of signals will he advertised shortly. The work can be finished long in advance of the stations, mains, etc., already referred to. The department favors and has recommended the extension of the highpressure fire system downtown, the new district to extend from Chambers street to the Battery and from the North river to the East river, and will shortly ask the necessary appropriation to carry this work into effect. The cost of this extension will be about $2,000,000. The Brooklyn stations arc at Furman and Joralemon streets and at Willoughby and St. Edward’s streets. The electric power for the new’ fireservice is to he generated in these stations. The electric plants for the Manhattan stations are to generate and transmit 3.250 kilowatts of threephase 6,600-volt 25-cycle electric power. The power of the Brooklyn will be the same, except that they are for 1,830 kilowatts. The plants will he ready in six months. By means of the new plant water can he pumped at a pressure . f 240 lbs., and it is said that even at Fifty-ninth street water may be forced to a height of 200 ft. at a pressure of 215 lbs., from the Gansevoort street station. The district to be protected is below Fiftv-ninth street and on the west side of the city, taking in the financial district round Wall street, the drvgoods district, the big hotel district and much of the best residential section
