Septic Solutions

A question we get a lot is “Can I install an old style septic tank?” The answer is yes, the Queensland Plumbing & Wastewater Code determines that you can install a septic tank, however the tank must be large enough to handle all waste from your home including grey water, and the trenches or absorption beds that handle the effluent must be large enough as well. Today’s guidelines are vastly different, and a standard home needs a lot more trenches than it ever did 30 plus years ago. Also, the soil must have a good permeability and be able to handle the amount of waste that your home will produce. Talk to us more about the options for your home.

Septic Absorption Trenches

Have your septic trenches failed? Are you looking to replace or install septic trenches?

You are still allowed to do this in Queensland, it’s just that there are tighter laws surrounding when you can have them, what soil they work best in and how big they need to be.

If you are looking at replacing or upgrading your septic tank or septic trenches contact us. We can inspect your system and work together to get the best solution for you.

Septic Tank Upgrades

Upgrading a Septic Tank system involves the deletion of the old tanks, and the diverting of all their essential plumbing into a brand new system.

Older systems which use traditional absorption trenches become increasingly prone to troublesome blockages and repeated failure. Additionally, these older systems can become less efficient over time as tree roots enter the trench system, or ground movement causes misalignment.

The upgraded systems used by Maxfield’s Wastewater bring all of your septic processes into one tank, named a Home Sewage Treatment Plant.

With all our Septic Tank Upgrades we will develop you a site-specific solution. We’re not locked to a particular brand or system, and our breadth of options enables us to provide a system that caters to your needs.

The Benefit of Upgrading your Septic Tank

Upgrading your septic tank saves you time, money, and inconvenience.

When a Home Sewage Treatment Plant is used, the need for an underground absorption trench is eliminated. This removes the external factors that cause older systems to break down.

Furthermore, the use of a HSTP will enable you to bring the number of tanks on your property down to one.

The reduction of the number of tanks on your property will save you money in the long run, as you no longer need to pay for services such as having a grease trap frequently emptied. Many of the additional services required to keep older systems running are labour-intensive, and can be costly and a major hassle to organise with a contractor.

How to Know It's Time to Upgrade Your Tank

Odours – The biggest telltale sign that it’s time to upgrade your septic tank system is if your current set up is producing noticeable odours.

Soggy or damp patches of grass – If you’re experiencing wet patches around your tanks or absorption trenches, then it’s time to investigate an upgrade immediately.

Toilets flushing slowly – If your toilets (or any other fixtures within the home) are taking an eternity to empty, this could be a sign it’s time for you to investigate an upgrade of your current system.

You can’t use your bathroom at all! – This is the doomsday scenario. If your bathroom is completely unusable because water cannot drain, then you need to have an expert take a look at your septic system immediately.

Installing a New Septic System

If you’re developing or building a new home on acreage, one of the very first things you’ll be required to do by your local council is provide a Wastewater Design. This can be an intimidating and confusing part of your build, and often leaves property owners stumped. You cannot begin construction on an unsewered block without a wastewater design. Make sure you get the first piece of the puzzle right! Call us to arrange.

Mistakes We Can Help You to Avoid

Your system will be installed for a lifetime, so we think you should have both your HSTP and your dispersal area, somewhere that won’t affect any future plans on your property. For example, you don’t want your HSTP right outside your entertainment area, or right where you may potentially build a driveway or pool. We think ahead and will discuss all the options with you. We will help you get it right, so you can be happy with your decision for years to come.

We also ensure the water pumped from your system will benefit you and your family. Water is so precious, so we’ll help you make the most of it.
A custom design will enable you to use clean, safe water in a way that boosts the sustainability and appearance of your property.
