HIGH-PRESSURE SYSTEM FOR NEW YORK.

HIGH-PRESSURE SYSTEM FOR NEW YORK.

It is the intention of the Department of Water Supply to use parts of the new high-pressure fire service plant, now being installed in the borough of Manhattan, New York, previous to the completion of the entire system. For this purpose a connection has been established between the Croton low-pressure service -the 48-in. main at Fifth avenue and Twenty-first street—and the new service pipes at Fifth avenue and Twenty first street. The district to be benefited by this plan is comprised within the following bounderies: Beginning at Twenty-second street and Fifth avenue, down Broadway and University place to Waverly place, westward through Waverly place and Christopher street to West street, northward through West to Sixteenth street, eastward through Sixteenth street to Seventh avenue, northward through Seventh avenue to Twenty-second street, with the exception of the block on Eighteenth strept from Sixth to Seventh avenues, and eastward through Twenty-second street to the corner of Twer.ty-second street and Fifth avenue. It comprises about 400 acres and embraces many of the most important retail dry goods districts. An interesting test was made a few days ago on the twenty-four-inch high-pressure main on Third avenue to determine whether the 20-in. gatevalves could !u' easily opened while under a pressure of 450 lbs. a sq. in. on one side and no pressure on the other, which is equivalent to a pressure of 71 tons on the valve-disk. It was found that two men working an ordinary gate-key with 2-ft. handles could readily open the valve.
