Overview
South Carolina's water systems serve coastal plain and piedmont regions experiencing growth and environmental challenges. The South Carolina Department of Health and Environmental Control regulates operations in a state with diverse water sources. Understanding both traditional surface water and emerging groundwater issues is valuable.
Applications and renewals are processed through South Carolina's official portal or website. Check with DHEC for current requirements, as regulations update regularly.

License Class Comparison
South Carolina uses a Grade 1-5 System classification system. The class your license needs to match the size and complexity of the facility you're designated responsible operator for.

| Class D/Grade 4 | Entry | Small systems | Limited experience, pass exam |
| Class C/Grade 3 | Intermediate | Small to medium systems | Prior class experience + exam |
| Class B/Grade 2 | Advanced | Medium to large systems | Prior class experience + exam |
| Class A/Grade 1 | Master | Large, complex systems | Extensive experience + exam |
Experience Requirements
Experience requirements in South Carolina are structured as a progression. You must accumulate documented experience at each level before advancing to the next class. Education (engineering, environmental science, etc.) can substitute for some experience, but check specific state rules for your category.
Keep detailed records of your experience: facilities operated, treatment processes, system sizes, dates, and supervisor verification. South Carolina audits experience documentation during application and renewal.
Pro tip for South Carolina operators: Document the full scope of your experience. Familiarity with specific treatment processes common in South Carolina (groundwater, surface water, reclaimed water, etc.) strengthens your license application and career trajectory.
