Overview
New Mexico operators manage desert water systems dependent on the Rio Grande River and limited groundwater resources. The New Mexico Environment Department regulates operations in an arid state with significant water scarcity challenges. Understanding desert hydrology and water conservation is essential.
Applications and renewals are processed through New Mexico's official portal or website. Check with NMED for current requirements, as regulations update regularly.

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