How to Become a Certified Septic Inspector

July 10, 2024

Septic inspectors play a crucial role in ensuring the proper functioning and safety of septic systems. Many homes and businesses, especially in rural areas beyond the reach of centralized sewer systems, rely on these systems to handle wastewater. Septic inspectors examine these systems to ensure they are in good working order and free of issues like backfill, which can compromise their efficiency and pose health risks to homeowners and their families. For instance, backfill can lead to sewage backups or groundwater contamination, potentially exposing residents to harmful pathogens. These systems not only prevent environmental pollution but also safeguard public health and save homeowners from expensive repairs. Not sure if a home has a septic system? Here’s a hint: if there’s no monthly sewer bill, it probably does!

The market for professional septic inspectors is growing. According to the U.S. Census Bureau, about 26 million homes (one-fourth of all homes) in America have septic systems. Septic tank inspections are more prevalent nowadays due to our increased awareness of environmental issues and higher frequency of septic system remodeling and maintenance requirements. This makes now an excellent time to consider a career as a septic inspector.

In this guide, we’ll walk you through the steps to becoming a certified septic inspector. We’ll cover the necessary education, training and certifications, along with tips on starting your own septic inspection business. Whether you’re looking for a new career path or an opportunity to expand your skills, becoming a certified septic inspector offers a rewarding and in-demand profession. You may also want to consider becoming a certified home inspector to boost your revenue streams and diversify your services, which can open more opportunities and enhance your professional growth.

The Role of a Septic Inspector

A septic inspector’s primary job is to ensure septic systems are functioning properly and comply with health and environmental regulations. These systems are responsible for treating and disposing of household and commercial wastewater in areas not connected to centralized sewer systems.

Types of Inspections

Septic inspectors conduct both residential and commercial inspections to ensure the proper functioning and safety of septic systems.

Residential inspections focus on septic systems installed in single-family homes. These inspections are often required during real estate transactions to ensure the system is in good condition before a sale. Homeowners may also request routine inspections to maintain their systems and prevent potential issues from arising later down the line. It’s important as a septic inspector to outline the risks associated with unmonitored septic systems, including possible exposure to diseases like hepatitis or dysentery.

Commercial inspections involve larger and often more complex septic systems used by businesses, schools and other institutions. These systems handle a higher volume of wastewater and may have more stringent regulatory requirements due to potential exposure to a larger group of people and liability concerns. Regular inspections help ensure these systems operate efficiently and safely, protecting public health and the environment.

Visual Inspections

Inspectors start with a visual assessment of the septic system components, including the tank, distribution box and drain field. They look for signs of damage, leaks and other issues that could indicate a problem.

System Testing

Septic inspectors conduct various tests to check the system’s performance. This can include hydraulic load tests to assess how well the system handles water flow and dye tests to detect leaks or blockages in septic systems.

Sludge and Scum Measurement

Inspectors measure the levels of sludge and scum in the septic tank to determine if it needs pumping. High levels of these materials can indicate that the tank is not being maintained properly and may soon overflow, causing system failure.

Documentation Review

Part of the inspection involves reviewing the system’s maintenance records and any previous inspection reports. This helps the inspector understand the history of the system and identify any recurring issues.

Reporting and Recommendations

After the inspection, the septic inspector typically provides a detailed report outlining their findings. They highlight any problems and recommend necessary repairs or maintenance. This report is crucial for homeowners, business owners and potential buyers to make informed decisions about their properties.

Septic inspectors play an essential role in maintaining public health and environmental safety. By identifying and addressing issues early, they help prevent costly repairs and environmental contamination, making their work vital to communities that rely on septic systems.

Educational Requirements

Becoming a certified septic inspector doesn’t require an extensive formal education, but having a solid foundation in certain subjects can be beneficial.

The minimum educational requirement for a septic inspector is typically a high school diploma or equivalent. This provides inspectors with the foundational knowledge necessary for further training and certification.

While in high school, focusing on specific subjects can give you a head start in understanding the complexities of septic systems and their inspection. Some recommended subjects include biology, chemistry and environmental science. While not mandatory, taking courses in mathematics and physics can also be beneficial. These subjects help develop problem-solving skills and an understanding of fluid dynamics, which are useful when assessing how septic systems manage and treat wastewater.

Continuing Education

After high school, consider enrolling in vocational training or community college courses related to plumbing, wastewater management or environmental health. These programs often offer more specialized knowledge and hands-on experience that can be directly applied to a career in septic inspection. Additional education can also propel your career beyond one trade discipline – expanding revenue streams and bringing you more value.

In addition to formal education, obtaining relevant certifications and undergoing specialized training are crucial steps in becoming a certified septic inspector. We will cover these aspects in more detail in the next section.

Getting the Right Training

Online courses offer flexibility and convenience, allowing you to learn at your own pace.

These courses cover topics such as septic system design, operation, maintenance and inspection techniques.

Community colleges are another option, often offering certificate or associate degree programs in fields related to septic inspection, such as environmental science, wastewater management or plumbing technology. These programs provide more in-depth knowledge and practical skills through a combination of classroom instruction and lab work.

Participating in fieldwork provides valuable, on-the-job training where you can practice inspecting actual septic systems under the supervision of experienced professionals. This practical experience helps you understand the daily responsibilities of a septic inspector and offers networking opportunities, which can sometimes lead to job offers later down the line.

1. Create a Business Plan

A solid business plan is essential for the success of any new business. It serves as a roadmap for your venture and helps you stay focused on your goals. Your business plan should include several key components to ensure a comprehensive and effective strategy. Start with an Executive Summary, which provides a brief overview of your business, including the mission statement and objectives. Next, conduct a Market Analysis to research the demand for septic inspection services in your area, understand your competition, and identify your target market.

Clearly outline the services offered by providing a detailed description of the services you will provide, such as residential and commercial inspections. Develop a Marketing Strategy that details how you will attract and retain clients. Additionally, include Financial Projections that estimate your startup costs, operating expenses and projected income.

Finally, create an Operations Plan that outlines how you will run your business, covering aspects such as staffing, equipment and processes.

2. Obtain Necessary Licenses and Insurance

To operate legally and protect your business, you need to check with your local government to determine the specific licenses required for a septic inspection business. Ensure you and your staff have the necessary certifications, such as those from the National Association of Wastewater Technicians (NAWT) specific to the septic inspection industry.
