Flooding and malfunctioning septic systems are common in Miami neighborhoods, contaminating waterways with untreated sewage.
Sea levels in the South have risen significantly, pushing groundwater higher and compromising septic system functionality.
Miami-Dade County is investing heavily to replace septic systems with municipal sewer connections, a costly and extensive project.

Why this matters:
Septic systems, which manage waste from homes and businesses not connected to centralized sewer systems, are designed to treat and disperse wastewater safely into the ground. However, with the water table rising due to climate change, these systems are increasingly unable to function properly. When groundwater levels rise, they can inundate the drain fields of septic systems, causing untreated or partially treated sewage to back up into homes or, worse, leach into the environment.
As seas rise, groundwater levels in coastal areas do, too. So when a storm hits, water can inundate people’s septic systems. Some residents in low-lying Beaufort County, South Carolina, are already facing the disgusting consequences.
