Septic Tanks Darwin

While a septic tank may not be the most glamorous choice for your home, making sure you have the best available can make a big difference to how your home works for you in the long term.


People who live on mains supply may take good sewage treatment for granted, but for those of us who rely on a septic tank day to day, it makes an enormous difference to the functioning of your home.


Let’s take a look at how septic tanks work, and the differences between a good and a bad installation.

Septic tank installation


Septic tank installation is a delicate and messy process, and if it’s not done right, it can create a number of problems down the line that can cost money and create an unpleasant mess! That’s why it’s important that you have installers who know what they are doing.

Septic tank installation requires a number of skills including excavation and site management, plumbing, electrical wiring and water management, which many contractors don’t possess.


The first problem is surveying the site and making sure you know where the tank is supposed to be, which can be a serious concern because of potential groundwater contamination.


The next is conducting the excavation carefully and properly, making sure the tank is secure and on solid ground, then the whole system has to be properly set up including connecting the septic system to existing pipes. 


We advise that this is done by an expert. If you need your septic system installed, give us a call on (08) 8947-1192  today. We have a team of experienced septic system installation experts!

How does a septic system work?


A properly fitted septic tank needs minimal maintenance and is a self-sufficient way of treating your own water. The wastewater flows into the tank where the solids sink to the bottom to be digested naturally by bacteria, while other compounds known as scum floats to the surface.


The middle layer of relatively clean water can then be pumped away in pipes to be released into the groundwater, where it naturally filters into the soil free of anything unpleasant to get into the groundwater.


Clearly, there is the potential for a lot of unpleasantness if the system doesn’t work properly, which can even get you into legal trouble if your tank pollutes the groundwater with sewage.


Benefits of a septic tank


The key benefit of a septic tank is that it allows you to have proper sewerage and drainage while living off the main sewer grid, which means you can site your house wherever you want it to be without having to worry that you won’t be able to use normal plumbing!


It’s also eco-friendly and efficient, disposing of your waste with minimal water loss and without having to use any nasty chemicals. It’s also a very low maintenance solution that has a long-life expectancy, so your value for money is high.
