There are several different drainage and sewage storage and treatment options that can benefit your home. Many of these are the perfect solution if you are in a remote location where you cannot connect to the main drains.

There are, however, a variety of additional benefits to installing a septic tank/treatment plant – it is a far more efficient system and has low running costs. Additionally, in many cases, this option is better for the environment.

This guide will teach you everything you need to know about septic tanks, from choosing the right size and type for your property, to avoiding common problems and details on costs.

Your Options

If you are thinking of installing or replacing a septic tank in your home, there are several options available to you. Our expert staff will evaluate your needs and recommend what we think is best for your property, taking into consideration your needs and your budget.
Available options include:


A septic tank is based underground and has two chambers. Solids settle at the bottom of the first tank and start to break down as wastewater reaches it, while liquid moves onto the second chamber. Water can then drain from the tank through the soak-away.


Some properties are not eligible for a septic tank as they cannot have a connection that is fed by gravity, as the wastewater won’t flow naturally from the property into the main sewer. In these cases, we recommend a pumping station option which has a pump that aids waste removal.

Treatment Plant

Unlike septic tanks, installing your own sewage treatment plant allows you to get rid of waste without having to empty it periodically. A treatment plant separates your waste, and breaks it down, before releasing the water.
