Stormwater Pump Station at Miami Beach Convention Center
SCOPE OF WORK
A&P Engineers’ team, on behalf of the City of Miami Beach, recently finalized the construction of one of its biggest stormwater pump stations. This pump has the capacity to move 80,000 gallons per minute (gpm) and is just one of 80 stormwater pump stations the City will construct within the next 8-10 years in order to combat the tidal events and sea level rise.
As part of this drainage improvement project, a 96” trunk line was also constructed in this initial phase. The pipe was designed as a collector pipe to receive flows from Collins Avenue and the surrounding streets; this will completed in the near future in the final phase.
This design was intended to serve as the prototype for the other pump stations that t he City plans to construct in the future. In the initial phase of the pump station, trash racks capture solids that are 1” or larger before the flow reaches the Collins Canal. The remaining flow is split into trains, with a capacity of 40,000 gpm, and is directed to a water treatment structure and then a wet-well equipped with 2 20,000 gpm axial pumps. The pump station has been designed with overflow structures for redundancy and to prevent intrusions from tidal events. This project also saw the construction of a higher seawall, with a minimum top elevation of 5.70’ NAVD, to ensure our design’s resiliency against future conditions.
