How Often Should My Septic Tank Be Serviced?

November 29, 2022

You've just moved into a home with a septic tank but don't know very much about them. You've been told that septic tanks must be serviced regularly in order to ensure their proper functioning and longevity. But you're still left wondering 'how often should my septic tank be serviced?' Read on to solve the mystery! 

What is a septic tank service?

A septic tank service is important to ensure the tank and its related systems operate properly. It includes checking the system for leaks, cleaning the filters and making sure the drainage area is clear. It also involves pumping out the sludge and scum from the tank to prevent solids from accumulating. In addition, periodic inspections should be done to ensure the system is in good working order. Proper maintenance can help prolong the life of a septic system and reduce health risks associated with contaminated water.

How often should my septic tank be serviced?

The frequency you should have your septic tank serviced could be anywhere between 1-5 years. Factors such as its age, how many people live in your home and how often the toilet is flushed will determine how often the septic will need servicing. It's also important to note that there are many different types of septic tanks available, which will also determine how often you'll need a service. These include: 

Concrete septic tanks

These have been used for wastewater treatment for many years. 


They are simple, durable and relatively inexpensive; however, they can only handle a limited amount of wastewater and require regular maintenance in order to function properly.

Steel septic systems

Steel septic systems are a relatively new product that are gaining popularity. They have many advantages over traditional septic systems, including durability and low maintenance requirements. Steel tanks are resistant to corrosion and damage from normal wear and tear, meaning they can be expected to last much longer than other septic systems. Additionally, these tanks require very little maintenance, as they don’t need to be pumped out as often as traditional systems.

Aerobic septic tanks

Aerobic septic tanks use a process called aerobic digestion to break down the waste in the tank. This is done by adding air to the tank, which encourages the growth of bacteria that eat away at the waste.


The result is that less harmful pollutants are released into the environment, and the water that is discharged from the tank is much cleaner than traditional septic systems.


Aerobic septic tanks do need to be maintained often, typically every few years depending on the size of the tank and how often it is used.

Signs that my septic tank needs to be serviced 

If you notice any of the following signs, it may be time to have your septic tank serviced:

  • Slow drainage in sinks, tubs & toilets
  • Gurgling noises coming from drains & toilets
  • Wet spots or standing water on the ground near the tank
  • Foul odours coming from the tank or drains

If you notice any of these signs, contact a professional to arrange a service. They'll identify the cause of the sign and the solution, preventing further issues occurring.

What happens if I don't service my septic tank?

If you don't service your septic tank, it can cause a lot of problems. The most common problem is sewage backing up into your home. Not only is this unpleasant, but it can also be dangerous to your health. Other problems that can occur if you don't service your septic tank include:

  • Septic tanks filling up too quickly or overflowing 
  • Soil & groundwater contamination from untreated sewage 
  • Your septic system will need to be completely replaced
