Septic tanks are a very useful and reliable alternative to traditional drainage methods. However, there are a lot of queries and uncertainties surrounding them so this guide goes over the most frequently asked questions and clarifies how they’re such a useful addition to your domestic property or industrial facility.

From maintenance to lifespan, here’s everything you’ll need to know about septic tanks:

How Do Septic Tanks Work?

Septic Tanks are an alternative drainage method where waste goes into the tank and is separated over time. Harder solids go to the bottom of the tank due to gravity, whereas oil, grease and lighter solids float to the top to form a ‘scum’ layer. Depending on your model of tank, this may then be taken to a drainfield or what’s termed a ‘leach box’ where it will be distributed.

How Long Do They Last?

Generally, septic tanks last roughly 40 years which means it’s important to figure out how old your model is. It might not require changing for another 40 years or it could have gone well past this estimate but you won’t know unless you check!

How Often Should They Be Cleaned?

As a general rule of thumb, it's best practice to have your septic tank cleaned out every couple of years, though some people will choose to wait until every five years or more. Having them cleaned out is the best way to keep them maintained. It’s a more cost-effective maintenance method to pay a small up-front cost and have them regularly cleaned than avoiding the inevitable and facing high repair and replacement costs in the long run.

How Do I Know When It’s Full?

There are a number of tell-tale signs that your septic tank has reached full capacity, or at least a level where it should be cleaned out at the earliest convenience.

●     Strong odours around the septic tank and taps/toilets

●     Pooling water by the septic tank

●     Drains take a lot longer than usual to get rid of water

●     When the sewer has backed up to a lower plumbing fixture

●     Algae growing in nearby water



How Can I Make My Septic Tank Last Longer?

As previously mentioned, regularly cleaning out your septic tanks is a great way to ensure they last longer. You should also refrain from flushing solid objects, be conservative with water drainage, and avoid putting oils down the drain.
