Septic tanks are an important part of sewage disposal, and it’s important to ensure safety when dealing with them. That’s why a license or certification is required in most states. In this blog post, we’ll cover everything you need to know about septic tanks: licensing, safety, and more!


How does a septic system and tank even work? Septic tanks are designed for the disposal of sewage. A septic tank and a drainfield, or soil absorption field, are the basic components of a typical sewage system. Organic waste is broken down by the septic tank, floatable matter (such as oils and grease) is separated from the wastewater, and solids are removed. Soil-based systems send the liquid (also known as effluent) from the septic tank into a series of pipes disposed in a leach field, chambers, or other specialized units meant to slowly release the effluent into ground. 


In rural areas, sewage waste material is decomposed through the action of anaerobic bacteria in a large tank rather than being sent to a wastewater treatment plant in urban areas.  Septic tanks come in a variety of sizes, but most septic tanks are designed to operate using a continuous flow method.


So why do you need a license to install a septic tank? Septic tanks are an important part of sewage disposal, and it’s important to ensure safety when dealing with them. Septic tanks are designed for the disposal of sewage, which can contain harmful bacteria and other contaminants. If septic tank waste isn’t properly disposed of, it can contaminate groundwater and surface water, which can lead to serious health problems. That’s why licensing is required in most cases. A license ensures that the installer has the proper training and knowledge to safely install the tank. In addition, most states require septic tank installers to be licensed. Some states offer several septic-system-related certifications, such as residential, commercial and drip-emitter system certifications. These certifications ensure that Septic Tank Installers know what they’re doing and can properly install and maintain septic tanks.


How do you get a license to install a septic system? Obtaining a license or certification as a septic tank installer generally entails submitting an application with your background and professional experience, paying an yearly fee that is renewable, and passing an examination covering installation, operational details, and safety procedures. Septic tank professionals are typically required to pass a comprehensive exam to become licensed to install or repair septic systems. Some states, such as Minnesota, require that septic system-related businesses have an additional business license and bonding.


If you are looking to have a septic system installed, you must acquire both a license and a permit from your state or local government. They will need to fill out an application, including paying any applicable fees, then wait for an inspector to come inspect the proposed location. If the site is approved, you will be given a list of certified septic tank contractors to pick from. In most states, septic tank permits are valid for five years.
