From: Anthony Ragucci, P.E. Chief, Maintenance Section FEB 1 9 1388 Subject: I.D. #736 Amtrak leaks on Riverside Drive, Manhattan and CONTROt z D.F.O. 87-139
In response to a request dated July 21, 1987 regarding leaks on the Amtrak Railroad at the west side connection (Riverside Drive), an engineering investigation was conducted and the following was f ound.
1) On Riverside Drive and West 147th Street A leak was observed on the track. Dye tests and T.V. Inspections reveal that the 15" combined sewer at West 147th Street is not connected to the 3'-6"x2'-4" sewer on Riverside Drive as shown in North River drainage arsa analysis.
The 15" sewer is 4 feet lower than the 3'-6"x2'-4" brick sewer. The 15" sewer would normally go to the river but is now collapsed and the sewage exits through the broken manhole west of Riverside Drive onto the Amtrak Railroad. It is recommended that the 15" combined sewer at West 147th Street and Riverside Drive be connected to the 3'-6"x2’-4" brick sewer under capital project. We will perform trap elevation survey in preparation for the eapital project to connect the 15" sewer to the 3’-6"x2’-4" brick sewer.
2) On Riverside Drive and West 144th Street
A leak was detected and a sample analysis and dye test was performed. It was proven to be sewage. A sewer break repair sheet (CC#87S069858) has been submitted to reconstruct sewer break at West 145th Street between Broadway and Riverside Drive. (See attached sheet).
