Operator License Reciprocity by State
Moving with a water or wastewater operator license? Reciprocity rules change often and every application is reviewed individually, so the only answer that counts is the one from the state you're moving to. Here is every state's official certification program in one place. For how reciprocity works in general, see our reciprocity guide.
