This is part of an interview on PBS Nightly News. The interview was generally positive, good for Miami Beach for getting rid of the storm water. (The storm water sewers don’t drain into the ocean as reliably as it used to, now that the ocean often rises above the level of the sewers.) I guess the ground water under southern Florida isn’t good for too much, but surely there is some potable water down there. Otherwise where do the locals get their drinking water? (Wal-Mart?)
Regulations in most other locations require strict isolation of surface water from ground water. The damages ensuing from a contaminated aquifer are incalculable.
Maybe they pump the storm water underground in an attempt at remediation: reducing the number of sink holes on the surface that are caused by pumping fresh water out of the ground. Still – it’s nuts to pump storm water underground.
KWAME HOLMAN: The Miami Beach Public Works Department is working on improvements now.
ERIC CARPENTER, Miami Beach Public Works Department: We have done our storm water management master plan that was adopted in 2012, and that had identified approximately $200 million worth of improvements that we needed to do over the next 20 years in order to keep pace with sea level rise and addressing flooding concerns within the city of Miami Beach.
KWAME HOLMAN: Some of that infrastructure includes pumps.
RICK SALTNICK, Senior Capital Projects Coordinator: Everything collects on the inlets on the streets and then runs through those white pipes down there. They’re PVC pipes. They then all drain via gravity to the storm water pump station, and then pumped out of the storm water pump station and injected into the ground 80 to 100 feet down.
We’re sizing these pumps to provide the proper level of service 20 years from now and at the sea level 20 years from now.
