Septic License Requirements in Vermont
We all need safe, reliable sewage management for our homes and businesses. Those homeowners and businesses that rely on septic tanks, also known as on-site sewage facilities (OSSF), depend on people who know how to install and maintain those systems while protecting public health.
Vermont State University's DEC-partnered wastewater program reports that about 55% of homes in Vermont rely on septic systems, the highest share of any state.
According to the Bureau of Labor Statistics (BLS), there are 30,650 septic tank servicers and sewer pipe cleaners nationwide, and Vermont employs about 140 of them based on the most recent state data. Employment is projected to grow 8% from 2024 to 2034 across the country, opening roughly 2,900 jobs each year, according to CareerOneStop, the U.S. Department of Labor's job search website. In Vermont, employment in this occupation is projected to hold steady over the same period.
Demand for skilled trades work remains strong. Vermont relies more heavily on on-site septic systems than any other state, so trained designers and installers who keep those systems safe and compliant are consistently needed. If you get the training you need, you should have steady work to choose from once you are licensed.
If you're thinking about starting a septic business or working in the wastewater management field, you need to know the requirements in your state or local jurisdiction. This guide will help you determine what you need before you get started in Vermont.
Types of Septic Licenses in Vermont
While a Class 1 Designer must be a licensed Professional Engineer, the Vermont Department of Environmental Conservation issues three Designer license types:
Class A Designer: Required for system design of wastewater systems that don't require site modifications and to design one potable water supply that will serve one single family residence. The wastewater system or water supply is limited to a design flow of 1,350 gallons per day or less.
Class B Designer: Required to design wastewater systems that may require site modifications or the use of general approved innovative and alternative products and to design one potable water supply that will serve one single family residence. The wastewater system or water supply is limited to a design flow of 1,350 gallons per day or less.
Class BW Designer: Required to design the same systems and supplies as a Class B designer and may design potable water supplies for 1,350 gallons per day or less for two or more single family residences, buildings, structures, or campgrounds.
None of the Designer classes requires prior licensed experience or a set apprenticeship, but each is earned by passing the corresponding exam, and the classes build on one another: Class A is the foundation, Class B requires the Class A material plus an additional written component, and Class BW requires the Class A and Class B material plus a further written component. A Class 1 Designer must be a licensed Professional Engineer. Vermont also offers a separate, voluntary WW Installer certification for contractors who install onsite systems.
Steps to Get a Septic License in Vermont
To obtain a Designer license, follow these steps:
Submit a Designer Exam Application Form.
Pay the exam fee: $75 for Class A (written and field exams) or $50 for either Class B written exam.
Pass the exam.
To obtain a voluntary WW Installer certification, attend the following free workshops offered by Vermont State University:

Soils and Installation Best Practices
Malfunctioning and Failed Septic Systems
Professional Engineers who want to become Class A Designers are required to take the Class A field exam for ANR Soil Compliance.
Benefits of Getting a Septic License in Vermont
There are several benefits to earning your Vermont Designer license:
It is required by law to design a potable water supply or wastewater system that needs a state permit.
A license is proof of your knowledge and skill.
It lets you legally offer design services and build a business around them.
It supports your ability to move projects through permitting and inspection.
It protects your customers and your business.
It can increase your earning potential as you move from Class A to Class B and Class BW.
What Is the Mean Wage for a Septic Professional in Vermont?
The annual mean wage for septic tank servicers and sewer pipe cleaners nationwide is $53,500, according to the U.S. Bureau of Labor Statistics. In Vermont, the median annual wage for this occupation is $46,140, with the top earners making about $62,750.
The difference between a mean and a median can be confusing:
Mean wage is the mathematical average of all wages.
Median wage is the point where half of workers earn less and half earn more, and is often a better picture of typical pay.
Pay can vary based on where you work, your experience, the license class you hold, the certifications you earn, and whether you own your own business.

How Long Does it Take to Get a Septic License in Vermont?

Vermont Septic Training Programs and Schools
Vermont Tech hosts preparation workshops for the Designer exams, as well as courses for Installer certification. Courses are available on traditional and alternative systems.
Vermont Septic Licensing Exam Details
Designers are required to pass an exam for licensure. Exam prep courses (optional) are offered through Vermont Technical College for a fee.
The Vermont Agency of Natural Resources (ANR) administers the Designer exams, while the license itself is issued by the Secretary of State's Office of Professional Regulation. The Class A exam has two parts: a written component and a field component that tests soil identification and the state rules. The Class B exam includes the Class A material plus an additional written component, and the Class BW exam includes the Class A and Class B material plus a further written component. Exams are based on the 2023 Wastewater System and Potable Water Supply Rules. You register for an exam through the ANR Online portal.

How Can I Prepare for the Septic License Exam in Vermont?
Vermont State University (formerly Vermont Tech), in partnership with the DEC, offers state-approved preparation workshops for the Class A written exam, the Class A soils exam, and the Class B and Class BW exams. These workshops walk candidates through the exam format, the types of questions asked, and the level of detail expected in answers. Because the exams test the 2023 Wastewater System and Potable Water Supply Rules and soil identification, reviewing the current rules and completing the soils workshop are the best ways to prepare.
In Vermont, a license is required to design water supply and wastewater treatment systems. This license is issued by the Vermont Agency of Natural Resources Department of Environmental Conservation.
In addition, the state's Wastewater System and Potable Water Supply (WW) Program, in partnership with Vermont State University, issues a voluntary WW Installer certification for contractors who install onsite wastewater treatment systems and potable water supply connections.
Does My Vermont Septic License Work in Any Other State?
No. A Vermont Designer license is valid only in Vermont. If you want to work in another state, you must apply under that state's rules. Likewise, anyone moving to Vermont from another state must meet Vermont's requirements before designing systems here.
Does Vermont Reciprocate Septic Licenses?
No, Vermont does not offer reciprocity agreements with other states for septic licensing.
Because Vermont does not offer reciprocity, out-of-state designers must apply through the Office of Professional Regulation's endorsement process or sit for the Vermont Designer exams.
National Septic Certifications
Other certifications can help you demonstrate your proficiency to potential employers and clients. The National Association of Wastewater Technicians offers certifications, and The National Onsite Wastewater Recycling Association offers education, training, and professional development for the onsite wastewater industry. Those and other professional certifications are not required but can add to your marketability and therefore increase your opportunity to make more money.
Other Requirements Unique to Vermont
A few things set Vermont apart. Designers apply, register for exams, and manage their credentials through the ANR Online portal, while licensing itself is handled by the Secretary of State's Office of Professional Regulation. Septic system installers are not licensed by the state; instead, Vermont offers a voluntary WW Installer certification through Vermont State University. Wastewater permit fees are set by each regional DEC office rather than a single statewide schedule.
Are There Septic Scholarships in Vermont?
There is no scholarship dedicated specifically to septic Designer licensing, but Vermont residents pursuing trades training may qualify for broader workforce funding. The Vermont Student Assistance Corporation (VSAC) offers an Advancement Grant for non-degree, short-term training and a Vermont Trades Tuition Benefit that can cover tuition for high-demand building, mechanical, and industrial trades. Confirm your program's eligibility with VSAC before applying.
How Can Someone Verify My Septic License in Vermont?
Clients and employers can confirm a designer's license status and disciplinary history using the Office of Professional Regulation's Find a Professional tool. To verify:
Open the Find a Professional search on the Office of Professional Regulation website.
Search by the designer's name or license number.
Review the license status, class, and any listed disciplinary history.
The DEC also publishes an annual list of licensed designers, and a conduct decision search is available for reviewing disciplinary cases.
When Can a Septic License Get Suspended in Vermont?
The Office of Professional Regulation can discipline or suspend a designer for unprofessional conduct, which includes:
Fraudulent or deceptive procurement or use of a license.
Failing to comply with state statutes or rules governing the profession.
Willfully filing false reports or records.
Conviction of a crime related to the profession or a felony.
Failing to practice competently.
A designer can also be disciplined under state law for certifying a design or installation that is untrue, incorrect, or non-compliant because of a failure to exercise reasonable professional judgment.
Note: The information above should not be considered legal advice.
What Are the Penalties for Unlicensed Septic Work in Vermont?
Designing a potable water supply or wastewater system that requires a state permit without a Designer license is prohibited in Vermont. Violations of the state's environmental laws are subject to administrative penalties of up to $42,500 for each violation, plus up to $17,000 for each day a violation continues, with a total cap of $170,000. The Secretary may enforce these orders through the Environmental Division of the Superior Court, and unpaid penalties can hold up any pending permit application.
Note: The information above should not be considered legal advice.
Do I Need to Renew My Vermont Septic License?
Yes, Designer licenses must be renewed every two years through the Secretary of State Office of Professional Regulation.
Continuing Education
Licensed Designers are required to complete 12 hours of continuing education credits every two years, including at least four hours in practical soil training. Credit hours must be endorsed by the Drinking Water and Groundwater Protection Division of the DEC. A list of pre-endorsed courses is available on the government website.
Designers renew their licenses every two years through the Secretary of State's Office of Professional Regulation, which handles renewals online and sends reminders by email. At renewal, you attest to completing the required credits and upload your course certificates. If your continuing education is not finished by the renewal date, you may request a provisional license once every four years for up to six months to complete it.
