Stormwater Pump Station at Miami Beach Convention Center

CHA, on behalf of the City of Miami Beach, finalized the construction of one of its biggest stormwater pump stations. This pump can 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 to combat tidal events and sea level rise.

As part of this drainage improvement project, a 96-inch trunk line was constructed. The pipe was designed as a collector pipe to receive flows from Collins Avenue and the surrounding streets.

This design was intended to serve as the prototype for the other pump stations the city plans to construct. In the initial phase of the pump station, trash racks capture solids that are 1 inch 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 two 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 feet North American Vertical Datum (NAVD), to ensure the design’s resiliency against future conditions.
