Concrete septic tanks and plastic septic tanks are both commonly used for residential and commercial sewage systems. Both types of tanks have their own unique pros and cons that should be considered when making a decision on which type of tank to use.
Pros of Plastic Septic Tanks
- Plastic septic tanks are lightweight and easy to handle, making them a popular choice for DIY installation projects.
- Plastic septic tanks are typically less expensive than concrete tanks, making them a cost-effective option for many homeowners.
Cons of Plastic Septic Tanks
- Lower strength: Plastic septic tanks are not as strong as concrete tanks and may not be able to withstand heavy loads or extreme weather conditions.
- These septic tanks may not be able to hold as much sewage as concrete tanks. This leads to more frequent pumping and maintenance.
- Plastic septic tanks may float or pop out of the ground if they are not properly anchored.
- Plastic septic tanks may require more frequent pumping and maintenance than concrete tanks due to their lower effluent levels.
Pros of Concrete Septic Tanks
- Concrete septic tanks are extremely durable and can withstand heavy loads and extreme weather conditions.
- These septic tanks can hold more sewage than plastic tanks. This reduces the need for frequent pumping and maintenance.
- Concrete septic tanks typically require less maintenance than plastic tanks due to their higher effluent levels.
Cons of Concrete Septic Tanks
- Concrete septic tanks are typically more expensive than plastic tanks, making them a less affordable option for some homeowners.
- They are heavy and difficult to handle. This makes them more challenging to install than plastic tanks.
- Concrete septic tanks can be difficult to repair if they become damaged, and repairs may require the services of a professional.
Frequently Asked Questions
Here is a list of the most common Frequently Asked Questions:
What kind of septic tank lasts the longest?
Concrete septic tanks are known for their durability and long lifespan. They can last for 40 years or more with proper maintenance and regular inspections.
What is the most environmentally friendly septic system?
Aerobic septic systems are considered to be the most environmentally friendly type of septic system because they produce a cleaner effluent than traditional anaerobic systems. These systems use oxygen to break down waste, resulting in fewer pollutants being released into the environment.
Is the grass always greener over the septic tank?
The grass is greener over the septic tank or drain field because the effluent from the septic system provides nutrients and water to the soil. The effluent contains high levels of nitrogen and phosphorous which acts as fertilizers and this can make the grass in that area appear healthier and lush. The water that is discharged from the septic tank can also contribute to keeping the grass in that area well-watered, making it look greener.
Final Thoughts: Are Concrete Septic Tanks Better Than Plastic
In conclusion, both concrete septic tanks and plastic septic tanks have their own unique pros and cons that should be considered when making a decision on which type of tank to use. Concrete septic tanks are more durable and have higher effluent levels and lower maintenance, but they are more expensive and more complex to install. Plastic septic tanks are more affordable and easy to install, but they are not as strong and require more frequent pumping and maintenance. Ultimately, the choice of tank depends on the specific needs and budget of the homeowner.
