Should I Buy a House With a Septic Tank? Pros and Cons

Buying a home is a huge investment, and there are a lot of factors to consider before making the purchase. From the location to the home’s size, there are many things to think about. One thing that is often overlooked is the type of septic system the home has.

What is a septic tank?

A septic tank is a watertight chamber made of concrete, fiberglass, or plastic with an inlet and outlet pipe. The inlet usually has a control valve to regulate the inflow of sewage water. Solid waste settles at the bottom of the tank, where bacteria decompose it into sludge.

Lightweight scum floats on top of the sludge layer. The outlet is located between the sludge and scum layers, allowing effluent to exit the tank while trapping solids and scum inside. Septic tank systems are mostly used in rural areas where there is no access to a municipal sewer system. They are also common in areas with high groundwater tables since they do not require a soil absorption field. Proper septic tank maintenance is essential to prevent clogging and environmental contamination.

Tips for buying a home with a septic tank

When it comes to buying a home with a septic tank, there are a few things you should keep in mind. They include:

  • Have the system professionally inspected

Before you acquire a home with a septic tank, it’s essential to have the system professionally inspected. This will give you an idea of the condition of the system and whether or not it needs any repairs.

  • Get a pump-out schedule

If you buy a home with a septic tank, get a pump-out schedule from the previous owners. This will keep you on top of maintenance and avoid any costly repairs down the road.

  • Understand the local laws

Although septic tanks are common in rural areas, some local laws may regulate their use. It’s important to understand these laws before you buy a home with a septic tank. By so doing, you can avoid any fines or penalties.

  • Be prepared for regular maintenance

Acquiring a home with a septic tank also means being prepared for regular maintenance. This includes pumping out the tank every few years and ensuring the system is in good working order.

  • Be mindful of what you flush down your drains

Once you have a septic tank, you must be mindful of what you flush down your drains. Avoid flushing anything apart from human waste and toilet paper to prevent clogs and backups.

Pros and cons of septic tank


  • Less expensive than connecting to the municipal sewer system

Connecting to a municipal sewer system can be costly, especially if the hookup fees are high. Septic tanks are less expensive to install and maintain.

  • It eliminates the need for a soil absorption field

Soil absorption fields require a lot of space and can be expensive to install. Septic tanks do not require a soil absorption field, making them ideal for small properties.

  • Saves money

Generally, septic tanks are less expensive to operate than municipal sewer systems. This is because you do not have to pay for sewage treatment.

  • Lasts long

As compared to municipal sewer systems, septic tanks have a longer lifespan. With proper care and maintenance, they can last for decades.


  • Requires regular maintenance

Septic tanks must be pumped out every few years to prevent solids from building up and clogging the system. They also require regular inspections to ensure they are functioning properly.

  • Can pollute groundwater

If septic tanks are not maintained properly, they can pollute groundwater with bacteria and other harmful contaminants. This can pose a severe health risk to people and animals.

Municipal sewer systems vs. septic tank: which is better?

The answer to this question is dependent on several factors, including cost, maintenance, and ease of installation. Ultimately, it’s up to the homeowner to decide which system is best for their needs.

If you are considering buying a home with a septic tank, be sure to have the system professionally inspected and get a pump-out schedule from the previous owners. Understand the local laws regarding septic tanks and be prepared for regular maintenance. Remember to flush only human waste and toilet paper down your drains to avoid clogs and backups. Lastly, weigh the pros and cons of septic tanks against municipal sewer systems to decide which is best for you.

Final Thought

Overall, septic tanks have pros and cons that should be considered before purchasing. With proper maintenance, they can be a cost-effective and space-saving option for your home. However, it would help if you were prepared for the required regular upkeep. What is most important is to do your research and understand your options before deciding. Only then can you be sure that you are making the best choice for your needs.
