Overview
New Hampshire's water systems combine coastal operations and inland New England surface water treatment. The New Hampshire Department of Environmental Services regulates operators in a state with pristine lakes and rivers, and strong environmental protection traditions. Understanding New England water quality standards is important.

| Class A/Grade 1 | Master | Large, complex systems | Extensive experience + exam |
Experience Requirements
Experience requirements in New Hampshire 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. New Hampshire audits experience documentation during application and renewal.
Pro tip for New Hampshire operators: Document the full scope of your experience. Familiarity with specific treatment processes common in New Hampshire (groundwater, surface water, reclaimed water, etc.) strengthens your license application and career trajectory.
