How Often Should You Get Your Septic Tank Cleaned?

Dec 01, 2021

Thousands of homes and business properties in Australia have turned to construct septic tanks. They represent a minimisation of leakage compared to standard sewage systems and, because of their size and adaptability to smaller or rural communities, they are more efficient in both energy and space.


But what about when it comes to the maintenance of your septic tank? It can be easy enough to forget when it’s buried underground but the consequences of forgetting to have your septic tank emptied and cleaned could prove more than a headache for you.


When septic tanks are regularly cleaned and emptied by professionals who know how to maintain a septic tank, the system can last for decades. It’s one of the most sustainable and durable options for waste collection. 


However, it’s vital to stay on top of its cleaning.

When Should You Have Your Septic Tank Cleaned?

In general, the recommended amount you should have your tank cleaned is once every 3 to 5 years.


However, this can depend on three factors: the size of your septic tank, how many people in the property are using it, and what you are flushing into your septic tank.


The smaller your tank is, the more often you should have it cleaned – for the smallest size, this could be as often as once a year if you have four or five people in the house. While, for the largest size, this could be as little as once every eight or six years.


How Are Septic Tanks Cleaned?

The favoured method by reputable cleaning companies is hydro excavation. This is a non-destructive alternative that is cost-effective, proven to reduce inconvenience, and is safe for the public. 

This process uses high-pressure water to more effectively and safely excavate the septic tank without damaging any surrounding infrastructure, including underground utilities. Unlike other methods, hydro excavation does not endanger fibre optic cables, telecommunications, or underground power and water lines. 

Hydro excavation can trench below even concrete surfaces and confined spaces making it the ideal choice for hard to reach burial locations and making sure your land sees as little trauma as possible.
