“South Carolina’s dirty little secret”
South Carolina is growing faster than our pipes, pumps, and waterways can handle — and the numbers prove it.
We’re adding subdivisions, apartments, and commercial projects at record speed, but our sewer systems are already spilling millions of gallons of raw sewage into rivers, lakes, and neighborhoods every single year.
Lexington dumped 7.1 million gallons in 2025.
Columbia spilled over 4 million gallons in 2023.
Cayce, West Columbia, Fairfield, Newberry — every county is leaking, and development keeps climbing.
Here’s the truth nobody wants to say out loud:
Every new rooftop, driveway, and street adds pressure to systems that are already failing.
When you stack rapid development on top of outdated pipes, undersized pump stations, and overwhelmed wastewater plants, you don’t just get “growth.”
You get bigger spills, more contamination, more flooding, and more damage downstream.
If we don’t demand real infrastructure upgrades NOW — not later, not “in the next phase,” not “after approval” — then these problems won’t just continue…
They will escalate.
And the people who live here will be the ones paying the price.
Growth is fine.
Growth without infrastructure is a disaster.
And South Carolina is running out of room for excuses.
Today’s research form just a Homeowner;
2025
• East Richland PSD: 5 spills, 4,136 gallons
• Richland County Utilities: 1 spill, 2,000 gallons
• City of Columbia (partially in Richland): 66 spills, 549,005 gallons (most occurred in Richland)

📌 Summary — Charleston County Sewer Breaks (2023–2026)
Across four years, Charleston experienced:
• Major sewer main breaks (James Island 2023, North Charleston 2025)
• Pipeline failures (Plum Island 2024)
• Repeated wet‑weather SSOs (2023–2026)
• Chronic overflow hotspots in West Ashley
• Legal action due to longstanding Clean Water Act violations
• Thousands to tens of thousands of gallons spilled during multiple events each year
Charleston’s sewer failures are driven by aging infrastructure, tidal flooding, king tides, heavy rainfall, sea‑level rise, and rapid development — all documented by environmental groups and Charleston Water System itself.

HORRY COUNTY (Myrtle Beach)
This month alone, two separate wastewater spills were confirmed in Myrtle Beach after pipeline failures. These aren’t rumors.
These aren’t “maybe” events.
These are documented incidents reported by Grand Strand Water & Sewer Authority and verified by WPDE News.
📍 Spill #1 — August 2, 2026 (Southern Trail)
Source: WPDE News
• Pipeline failed 1,100 feet north of Southern Trail & Gardner Lacy Road. wpde.com
• Wastewater flowed directly into the stormwater pond beside Southern Trail. wpde.com
• SC Department of Environmental Services was notified.
📍 Spill #2 — August 12, 2026 (Forestbrook Road)
Source: WPDE News
• Pipeline failed 900 feet southeast of Forestbrook Road & Whatuthink Road. wpde.com
• Wastewater entered a roadside ditch draining into the stormwater pond behind 2495 Forestbrook Road. wpde.com
• SC Department of Environmental Services was notified.
GSWSA says both failures were “isolated,” but the pattern is anything but.
Horry County has seen repeated wastewater overflows for years — from lift station failures to line blockages to stormwater infiltration — and now two pipeline failures in ten days.
This is what rapid development without infrastructure accountability looks like.
Why this matters
Stormwater ponds aren’t designed to hold untreated wastewater.
They drain into creeks, wetlands, and ultimately the Waccamaw and the Intracoastal.
Every spill increases nutrient loads, bacteria counts, and environmental stress — and every “isolated incident” chips away at public trust.
The bottom line
These spills happened. They’re documented. And they’re part of a larger statewide trend: development outpacing the pipes meant to support it.
Horry County residents deserve transparency, accountability, and infrastructure that can handle the growth being approved.
If you live in the affected areas, GSWSA listed a public contact number: 843‑443‑8251. wpde.com
