Things To Know About Commercial Septic Systems

Septic systems are a vital part of modern life for homes and businesses that are outside the range of municipal wastewater management.

What Is A Commercial Septic System?

The US Environmental Protection Agency says that commercial septic systems are found in non-residential properties or properties with multiple dwellings, and have the capacity to serve at least twenty people per day.

Compared with residential systems, there are a few key differences that business owners need to be aware of when it comes to commercial septic systems. This includes the different types of septic systems available for businesses, how they work, and what kind of maintenance is required to keep them running smoothly.

Types of Commercial Septic Systems

There are two main types of septic systems available for commercial use: aerobic and anaerobic septic systems.

Aerobic septic systems rely on oxygen to break down waste, while anaerobic septic systems do not need oxygen to function. Both types of septic systems have their own advantages and disadvantages, so it is important to speak with a professional before deciding which commercial septic system installation is best for your business.

In general, commercial aerobic septic systems are more expensive to install but require less maintenance over time, while anaerobic septic systems are less expensive upfront but may need more frequent pumping or other services.

What Is The Proper Septic Tank Size for a Commercial Building?

One of the most important factors in a commercial septic system is ensuring that the septic tank is the correct size. This is why it is especially important for commercial property owners to work with experienced professionals to design their septic system.

For instance, as the owner of a large property, a natural question might be: What is the largest septic tank available? However, a septic professional will consider the flip side to that question and ask: Can a septic system be oversized? The answer is yes because a septic tank that is too large will not process wastewater efficiently. Working with knowledgeable experts can save you time and money over the long run.

The appropriate size of a septic tank for a commercial building and the commercial septic system cost are going to be based on a few different factors:

  • How Many Occupants? The first factor is going to be the number of occupants that will be using the system.
  • What Type of Business? The second factor is the type of business that you are running. If you have a business that uses a lot of water, then you are going to need a larger septic tank. If you have a business that does not use much water, then you can get away with a smaller septic tank.
  • How Much Space Is Available? The third factor is the amount of space that you have available for the septic tank.


You should always consult with a professional when you are trying to determine the size of your commercial septic tank. They will be able to take all of the factors into consideration and help you determine the best size for your needs.

Commercial Septic Tank Maintenance

Because commercial septic systems get a lot of use, it is important that they be maintained properly.

How Often Should a Commercial Septic Tank Be Pumped?

The frequency of commercial septic pumping depends on the specific business and the volume of wastewater produced. While residential septic systems should be pumped at least every three to five years, the schedule for commercial septic pumping must be customized.

What Happens if There Are Problems With a Commercial Septic System?

If there are problems with your commercial septic system, it is important to get them fixed as soon as possible. The longer that you wait to get the problem fixed, the worse it is going to get. If the problem is left untreated, it could eventually lead to the failure of the entire septic system. This would be a very costly repair and it could cause a lot of damage to your business and to the environment.

How Do You Know If Your Commercial Septic System Needs Service?

There are a few signs that you can look for that will indicate that your commercial septic system needs service.

  • Sewage backing up into the building is the most serious – and obvious – sign.
  • An increase in the amount of water pooling around the septic tank might be a sign of a serious clog or broken pipes.
  • Another sign is an unpleasant odor coming from the septic tank or drain field.


If you notice any of these signs, it is important to call a professional as soon as possible.

What Is The Cost of Commercial Septic Tank Maintenance?

The cost of commercial septic services is going to vary depending on the problem that needs to be fixed. If you have a small problem, it is likely that the repair will be relatively inexpensive. However, if you have a large problem, the repair could be costly. A septic professional can assess the situation and determine the proper course of action.

Proper Care For a Commercial Septic System

No matter what type of septic system you have, proper day-to-day care is essential to keeping it running smoothly. This means being careful about what you flush or pour down the drains in your business. Avoid grease, oils, fats, chemicals, and anything else that could clog or damage your septic system.

It is also important to have your septic system pumped regularly; most commercial septic systems need to be pumped every three to five years, but this can vary depending on the size of your tank and the amount of waste your business produces.

Septic systems are an essential part of modern life, but they require care and maintenance to stay in good working order. If you are having problems with your commercial septic system or if you think it might need service, the best thing to do is to call a professional. They will be able to assess the situation and give you an estimate of the cost of repairs. They will also be able to give you some advice on how to avoid future problems with your septic system.
