A major UN report released this week shows the sea level is rising around the globe, which means people who live in coastal cities face real risks from losing their property, and in some cases their live, to the rising ocean and the intense storms these warmer waters bring.

And it will make it harder for more than 60 million people in the United States to flush their toilets.

About 1 in 5 US households rely on septic systems, according to the US Environmental Protection Agency. It’s a type of sanitary system that has worked since ancient Egyptian times, but the climate crisis and septic systems don’t mix, studies show.

These systems will be incredibly vulnerable to sea level rise and heavy rains. The climate crisis has brought both. In areas with drought, it may also be difficult to get the volume of water needed to keep the tanks functioning, studies show.

Many systems are clustered in coastal areas that are already expecting sea level rise, including around Boston and New York. Nearly half of New England homes depend on them.

Florida also has a disproportionate share. It’s home to 2.6 million systems, or about 12% of all the septic systems in the country, the Florida Department of Health estimates. Miami-Dade County alone is home to more than 105,000 septic systems.

“Sea level rise is not a registered voter. It doesn’t have a party. It’s something that is going to affect everyone,” said Rebeca Sosa, vice chairwoman of the Miami-Dade County Commission, who spearheaded a study on septic tank vulnerability in the county.

She knows it’s not a glamorous political issue, but with a lot of her residents living on Social Security checks, they’re not going to have the extra funds to deal with the issue.

“Our job right now is to make sure that we make the state and the federal government understand … that we need help, so we can help those who are not going to be able to pay to have sewer lines.”

A county report predicts that within the next 25 years, 64% of the tanks could break and need repairs every year. The report found there are likely 1,000 properties already failing under current conditions.

That’s bad news for residents, but news that will keep some workers busy.

‘Contamination is a real possibility’

When Jason and Brittnie Nesenman were high school sweethearts, never in a million years did they picture themselves standing where they are today: Together, hovering over someone else’s poop.

Jason and Brittnie Nesenman have a lot of extra work fixing septic systems that are vulnerable to the climate crisis.

Jason gets a better angle on a bright blue corrugated hose as Brittnie oversees the operation. The hose runs from their tanker truck, painted with their company’s colorful slogan, “We love your stinkin’ business,” into a septic system. Workers concentrate as they move boards and branches. Together, they clean the tank dug into the side yard of a million-dollar home.

Brittnie shakes her head and laughs, as she describes the fortuitousness of Jason’s decision to start Jason’s Septic Inc. 15 years ago. It certainly didn’t feel that way at the time.

“I was pregnant when Jason came home and told me he quit his job working for a local plumber. I actually gasped,” Brittnie said. “I was a massage therapist. We had no money.”

It may not have been the most romantic gesture when Jason swapped his beloved classic car for a septic draining tanker truck, but it gives the couple a sunny future at a time when the climate crisis darkens Miami-Dade County’s doorstep.

The systems need a certain level of unsaturated dirt to work, but the dirt is disappearing as the sea level is rising.

“With the sea level going up, the water table has risen up,” said Jason.

With a sewer system, he explains, water is whisked away to a water treatment plant.

With septic, the dirt around the tank filters out the contaminants. You flush your toilet, the waste fills a tank on property. Bacteria breaks it down. The heavier material falls to the bottom of the tank. Eventually, the effluent goes into underground pipes and gets released into the soil.

Septic tank repair workers flush out a septic system in Miami.

The higher water table is eating away at all that dirt.

“Everything floats downhill, if there’s no more downhill and you’re in the water, it’s just not going to work,” Jason explains. “So the systems, the older systems aren’t lasting as long.”

No soil means no filter, and no filter means contamination, Jennifer Cooper concluded in her 2016 study titled “Hell and High Water: Diminished Septic System Performance in Coastal Regions Due to Climate Change.”

“The combination of sea level rise and the wetter conditions and warmer temperature is going to be a problem for these systems, for sure,” Cooper said.

Rachel Silverstein, the executive director for Miami Waterkeeper, a nonprofit that fights to protect South Florida waters, eyes the area’s septic systems with real concern.

“Contamination is a real possibility,” said Silverstein. Broken septic systems mean when it floods people will be wading through waste that can make them sick.

If untreated sewage gets into area waters, it can create algae blooms and other ecological problems.

‘This is not a third-world country, this is Miami’

Even on sunny days, Miami is seeing flooding caused by the lunar orbit, which causes seasonal high tides, and what some scientists believe is rising sea levels due to climate change.

As he drives a golf cart from his tiny house real estate office to his lofted modern home, Marcelo Fernandes points to parts of his neighborhood road that flood.

Fernandes, a developer who sells homes in the area, says he has seen more floods due to high tides, even on days with clear skies.

His neighborhood is on septic. He’s worried about the sewage that will be in those flood waters when these septic systems break. Studies show this is a real threat to human health and to drinking water.
