10+ Pros and Cons of Septic Tanks

I love decorating my home and making little tweaks here and there.

Are you considering getting a sewage treatment plant for your home? If so, you’re probably wondering what the pros and cons of septic tanks are. Here I will provide a breakdown of the pros and cons of septic tanks that I am aware of.

Of course, if you’re considering getting a septic system, seek advice from a professional to see if it’s the right decision for you and your home.

First, let’s give a basic overview of how they work.

Septic tanks are installed underground and receive all sewage waste from your home. The solid waste settles at the bottom of the tank while the effluent is treated by bacteria in the tank. This process breaks down the waste and can then leave the tank and be distributed in a soil absorption field where it is further filtered before re-entering the groundwater.

What are the advantages of septic tanks?

There are actually some benefits that come with a septic tank – let’s break them down here:

1. Good for the environment

The main advantage of septic tanks is that they are much better for the environment than using a sewer. Because the waste water is cleaned naturally without the use of chemicals.

2. Inexpensive

Another advantage is that they are less expensive than sewers, especially if you live in a rural area. This is because you are not dependent on the main water supply and treatment plant, which can be expensive to run.

3. They generally last a long time

Septic tanks are also very durable and can last a long time if properly maintained. They are typically made of concrete, fiberglass, or polyethylene and should last for decades once installed.

4. Little maintenance required

Another benefit is that septic tanks require very little maintenance. You’ll need to have the tank pumped out every 3-5 years, but other than that, there’s not much you need to do. However, I would recommend that you have it checked fairly regularly to make sure everything is working as it should.

Be aware of potential warning signs such as wet patches in the yard, slow-flowing toilets or drains, sewage smells, and lush grassy areas. These could be signs that your septic tank needs some attention

5. Can be used in remote areas

Septic tanks are also a good option if you live in a remote area as they don’t require sewerage. This makes them perfect for rural households. That’s actually a big advantage, because you don’t have to rely on the municipal sewage system. This means that if there was ever a problem with the municipal sewage system, your home would still function as normally as your sewage treatment plant would still function.

What are the disadvantages of septic tanks?

Now that we have discussed some of the advantages of septic systems, let’s examine some of the disadvantages.

1. You can stink

One downside to septic tanks is that they can get smelly if not properly maintained (especially if you have a broken pipe). This is because the solid waste at the bottom of the tank can start to rot and produce methane gas. This gas not only stinks, but is also flammable.

2. They can pose a health risk

If the septic tank is not properly maintained, it can become a health hazard as the waste from the pit can seep into the groundwater. This contaminated water can then make people sick if they come into contact with it or drink it.

3. You need some space

Another disadvantage is that septic tanks take up a lot of space because they have to be installed underground. This means that you must have a large garden or yard for the septic tank to be installed.

4. You have to be careful what you flush into the tank

You also need to be careful what you flush down the tank, as certain things can clog the system – you don’t want clogged drains. For example, you should not flush things like diapers, pads or condoms down the toilet as they will clog the tank.

5. They can be expensive to repair

If you damage the pipe that leads to your tank or breaks it in any way, it can get expensive to fix since you’ll need to hire a professional to do it – not to mention it’ll be a really smelly and messy situation. If your septic tank needs to be pumped out more frequently than normal, this can also add up and become quite costly.

6. Unsightly

Another disadvantage is that they can be unsightly since you have to install a large tank in your yard. This can be a minor eyesore, especially if you have a small yard. However, there are a number of hacks you can use to safely hide them.

Should you get a septic tank?

Overall, there are both pros and cons that come with a septic tank. It’s important to weigh the pros and cons before making a decision on whether or not you should have one installed. Ultimately, the decision comes down to personal preference and your unique circumstances. If you think a septic tank is right for you then make sure you do your research and choose a reputable company to install it.

Basically, many of the disadvantages mentioned can be overcome if you maintain the septic tank really well and take proper care of it. The problems only really arise when you neglect it for too long.

Talk to a professional

The best thing to do when you’re undecided about getting a septic tank or not is to talk to a professional. They can value your property and advise you on whether or not it would be suitable for a septic tank. They can also answer any questions you may have about septic tanks. When deciding between sewer and septic tank, be sure to consult a professional to learn more and make the best decision for your home.
