Overview
Kentucky's water systems operate within the Ohio River basin and face unique challenges from historical coal mining impacts. The Kentucky Division of Water regulates operators managing systems affected by mine drainage and regional geology. Understanding coal-impacted water treatment is a specialized expertise in Kentucky.
Applications and renewals are processed through Kentucky's official portal or website. Check with KDOW for current requirements, as regulations update regularly.

License Class Comparison
Kentucky 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 | Level | System Size | Typical Requirements |
|---|---|---|---|
| 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 Kentucky 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. Kentucky audits experience documentation during application and renewal.
Pro tip for Kentucky operators: Document the full scope of your experience. Familiarity with specific treatment processes common in Kentucky (groundwater, surface water, reclaimed water, etc.) strengthens your license application and career trajectory.
