Septic tanks are an essential component of any household or commercial property that is not connected to a public sewer system. They are designed to collect and treat wastewater from the property before discharging it into the soil. Septic tanks come in various types, including built, plastic, and DIY septic tanks.
In this article, we will explore the differences between built, plastic, and DIY septic tanks and help you determine which one is best suited for your needs.

Susceptible to Damage – Plastic septic tanks are susceptible to damage from ground movement or heavy machinery. This can lead to cracks or leaks.
Poor Insulation – Plastic septic tanks have poor insulation and are more likely to freeze during cold weather.
DIY Septic Tanks
DIY septic tanks, also known as homemade septic tanks, are septic tanks that are constructed by property owners themselves rather than being purchased from a manufacturer or installed by a professional contractor. DIY septic tanks can be made from a variety of materials, including concrete blocks, plastic drums, or fiberglass tanks. They are typically cheaper than built or plastic septic tanks and can be customized to suit the needs of the property owner.
DIY septic tanks require property owners to have some knowledge of septic system design and construction. Property owners must ensure that their DIY septic tanks meet local and state regulations, which can vary depending on the location. In some areas, DIY septic tanks may not be legal, and property owners may be required to have a licensed contractor install their septic system.
Building a DIY septic tank typically involves digging a hole to the required depth and dimensions, constructing the walls and base of the tank using the chosen materials, and installing the inlet and outlet pipes. The tank is then covered with soil and gravel to provide additional support and prevent damage.
Advantages of DIY Septic Tanks:
Affordable – DIY septic tanks are the most affordable option. This is because the property owner can purchase the materials and construct the septic tank themselves.
Customizable – DIY septic tanks can be customized to suit the property owner’s needs. This means they can be designed to fit in small or awkward spaces.
Satisfaction – Property owners who construct their own septic tanks can take satisfaction in knowing that they built it themselves and saved money in the process.
Disadvantages of DIY Septic Tanks:
Inexperience – DIY septic tanks require a certain level of construction experience. Property owners who do not have experience with construction may make mistakes during the installation process, which could lead to problems down the line.
Code Compliance – DIY septic tanks must comply with local codes and regulations. Property owners who do not have experience with these regulations may not construct a septic tank that meets the necessary requirements.
Maintenance – DIY septic tanks require proper maintenance to function correctly. Property owners who do not maintain their septic tanks could end up with expensive repairs or replacements.
