Wastewater Treatment Training for Local Government and Municipalities

Wastewater treatment may operate largely out of public view, but it is one of the most important services local governments provide. Every day, municipal wastewater professionals help protect public health, local waterways, and the infrastructure communities depend on.

The scale of that responsibility is significant. According to the U.S. Environmental Protection Agency’s 2022 Clean Watersheds Needs Survey, the United States has 17,544 publicly owned treatment works (POTWs) serving approximately 270.4 million people. That represents about 82% of the U.S. population. The EPA also identified $630.1 billion in reported clean-water infrastructure needs over the next 20 years, including $66.6 billion for secondary wastewater treatment and $83.6 billion for advanced wastewater treatment.

Those numbers underscore why investing in wastewater infrastructure is critical—but infrastructure alone isn’t enough. Municipalities also need knowledgeable, prepared employees who can safely and effectively operate increasingly complex systems.

Building the Skills Behind Essential Infrastructure

Wastewater treatment facilities rely on operators and other public works professionals to maintain processes, identify problems, and help their agencies comply with environmental requirements. Training provides employees with the technical knowledge they need to understand not only what to do, but why each stage of treatment matters.

The Vector Solutions Water and Wastewater Training library provides online continuing education designed for water and wastewater professionals, with courses accepted in most states. The library helps agencies deliver training while supporting safety, compliance and continuing education needs.

For employees who need a foundation in the overall treatment process, the one-hour Wastewater Treatment course reviews primary, secondary and tertiary or advanced treatment while connecting wastewater operations to public health, environmental protection and applicable federal regulations.

Municipalities can also provide more targeted learning. Wastewater – Pretreatment and Primary Treatment examines mechanical pretreatment processes, primary clarification and organic contaminants. Wastewater – Secondary Treatment covers biological treatment, BOD and COD, process equipment, bacterial growth factors and secondary clarification.

The library also includes Water Treatment: Wastewater, Part 1, which walks learners through primary, intermediate and secondary treatment processes. For professionals who encounter industrial discharges, Essentials of Industrial Wastewater Treatment explores wastewater contaminants, treatment technologies, water analysis and approaches to treating water for discharge or reuse.

Why Wastewater Training Matters for Municipalities

For local governments, effective wastewater training supports several priorities at once. A well-trained workforce is better positioned to operate equipment effectively, understand treatment processes, recognize potential issues, and support regulatory compliance. Just as importantly, training helps municipalities develop institutional knowledge as experienced employees retire and new professionals enter the workforce.

As communities invest billions of dollars in maintaining and modernizing clean-water infrastructure, workforce development should be part of that investment.

“Investing in wastewater infrastructure also means investing in the people who operate it,” said Leslye Harrell, a product manager and course developer at Vector Solutions. “Ongoing training helps municipal teams develop the knowledge and confidence to meet evolving community needs.”

With accessible online wastewater education, municipalities can help employees strengthen critical skills while continuing to deliver the essential services their communities rely on.
