 FIGURE 2-4
Pressure Manifold Pier Piping and Ship Berthing Arrangement
b. Connections Flush with Pier Surface. For this type of connection
facility, recessed hose connections usually are located flush with the sur-
face of the pier, in which case the opening is covered by means of a grate
or steel plate. Openings for recessed receiving connections penetrate com-
pletely through the pier deck, allowing adequate provision for drainage.
2.3.5 CERTIFICATION TESTING OF PIER SEWER COLLECTION SYSTEM. Prior to
activating a new pier collection system, a thorough test shall be conducted.
The system, including gravity lines, pressure manifolds, riser connections,
wet wells, and transfer pumps, should be activated with an appropriate fresh
or salt water flow prior to hooking up ships and pumping sewage. Based on
the test results, the system shall be certified for use by the responsible
shore activity. Further, to insure the operational integrity of the pier
sewage collection system, any unusual or potentially hazardous circumstances
shall be noted and provided for in standard operational procedures.
