A pipe line that carries 25 million gallons of raw sewage is in the way of the Port of Miami dredging project and has a dubious lineage that poses a replacement challenge


Corals and seagrass aren’t the only fragile things in the path of a major Port of Miami dredging project.

There’s also a pipe carrying about 25 million gallons a day of raw sewage from Miami Beach, Surfside and Bal Harbour to a county treatment plant on Virginia Key. That’s a flow rate that would fill a backyard swimming pool with foul stuff every two minutes.

As if the job of relocating and replacing a sewage main running under the rocky bottom of a busy shipping channel wasn’t already challenging enough, an additional complication has significantly raised the risk factor of the $42 million project: The concrete pipe crossing Government Cut is of notoriously crappy quality itself — an aging, defective product blamed for numerous breaks across the county.

Recently, county engineers confirmed what Tobin had warned them about in a letter more than a year ago. The pipe was built by Interpace, a now-defunct company whose products have failed in a string of ruptures in the last few years, most notably, a 72-inch sewage main break that gushed raw sewage into Biscayne Bay last June. Over time, steel reinforcement wires inside the concrete pipes have corroded, broken and failed.

ruptures or not its going to cost money, money, money

egads! enough sewage to fill a swimming pool every 2 minutes.

all of the above just so larger ships can enter the harbor? the Barons will have their way.

1. A 72 inch sewage line!

Are you sure they're not confusing it with Rush Limbaughs yapper?

2. why are they dumping sewage in the gulf anyway?

They need to create a treatment plant.

3. Did I miss something?

"There’s also a pipe carrying about 25 million gallons a day of raw sewage from Miami Beach, Surfside and Bal Harbour to a county treatment plant on Virginia Key"

There is a treatment plant. Besides, Miami fronts on the Atlantic Ocean, not the gulf.
