Did You Know? — Marlboro County

Marlboro County is the birthplace of Blenheim Ginger Ale, one of the oldest bottled soft drinks in America. It originated in the late 1800s near the town of Blenheim when a local doctor began adding Jamaica ginger to the area's natural mineral spring water. The Blenheim Bottling Company was officially formed in 1903 and still produces its famously spicy "Old #3 Hot" formula that packs serious heat.

About Marlboro County — What Affects Your Septic System

Local Geography

Marlboro County Rivers, Watersheds, and Flood Zones

Marlboro County is bordered on the west by the Great Pee Dee River and is also drained by the Little Pee Dee River and Crooked Creek. The Great Pee Dee originates as the Yadkin River in North Carolina's Appalachian Mountains and flows 232 miles southeast through cypress swamps and bottomland forests before eventually reaching Winyah Bay. The river's wide floodplain along Marlboro County's western edge is a designated FEMA flood zone with poorly drained soils, and septic installations in these areas require careful evaluation and often elevated or engineered system designs.

Seasonal Tips

Year-Round Septic Awareness in Marlboro County

In Marlboro County's sandy Sandhills areas, summer droughts can cause soil to shrink away from tank and pipe connections, creating gaps that allow root intrusion and surface water infiltration when rains return. In the clayey upland areas, winter and spring rains can keep soils saturated for weeks. Inspect exposed risers and cleanouts in spring for signs of shifting, and keep trees and deep-rooted shrubs at least 30 feet from your drain field to prevent root damage.

Common Issues

Variable Soil Conditions Across Marlboro County

Marlboro County's geology spans from deep sandy Sandhills soils in the western portions to moderately permeable clayey marine sediments (the Marlboro soil series) on upland areas. Sandy Sandhills soils drain too quickly, allowing effluent to pass through without adequate treatment before reaching groundwater. Conversely, the clayey upland soils can be slow to absorb, leading to drain field ponding. A Professional Soil Classifier is especially important here to match the system design to highly variable site conditions.

What People Are Saying

We were tired of dealing with a discount pumper who just wasn't getting the job done! Our septic system was backing up every 3 to 6 months. Finally, we called Septic Workz. They used the Crust Buster to get all the solids out and then added commercial chemicals to help balance our tank. Three years later, we still haven't experienced any backups!
