Wastewater Operator: What Is It and How to Become

If you’re interested in a career as a wastewater operator, there are several important steps you’ll need to take. Wastewater operators are responsible for treating domestic and industrial wastewater to ensure it meets regulatory standards before it is released back into the environment. These operators play a crucial role in protecting public health and the environment, making it a rewarding career choice.

The first step on your journey to becoming a wastewater operator is to enroll in a state-approved training program. These programs are divided into different levels, ranging from entry-level courses to specialized courses for experienced operators. One reputable training program is TREEO, which offers a variety of classes and certifications to help you get started.



Once you’ve completed the necessary training program, you can apply for a wastewater operator-in-training (OIT) certification from your state’s environmental agency. This certification allows you to work under the supervision of a licensed operator and gain practical experience in a wastewater treatment plant. OIT certifications typically require passing an examination and may have additional requirements depending on the state.

After gaining experience as an OIT, you can then apply to become a fully licensed wastewater operator. The requirements for licensure vary by state, but they often include a combination of education, experience, and passing an examination. Some states may also require proof of a high school diploma or GED and a letter of acceptance into a wastewater operator program.

It’s important to note that wastewater operator licensing is state-specific, so it’s crucial to research the relevant statutes and requirements in your state. These requirements can change, so it’s important to stay up-to-date with any changes that may affect your licensure.

Once you’ve obtained your wastewater operator license, you’ll need to renew it regularly to ensure it stays valid. Renewal requirements may include completing continuing education courses, passing exams, and paying renewal fees. The frequency of renewal varies by state, but it’s typically every four years.



Becoming a wastewater operator can be a rewarding and satisfying career choice. Not only do you get to make a difference in public health and the environment, but you also have opportunities for career advancement and specialization. By following these steps and putting in the time and effort, you can become a highly skilled wastewater operator and contribute to the protection of our water systems.

GED Acceptance

Water/wastewater operator programs are intended to ensure that those becoming certified have the necessary knowledge and skills to operate water and wastewater systems effectively. Therefore, it is essential to have at least a GED certificate to enroll in these programs.

If you already have a GED and want to become a certified water/wastewater operator, it is recommended to research and reach out to the relevant licensing authority in your area to determine the specific requirements and steps to take. Each state or region may have different statutes, policies, and fees in order to comply with their certification process.
