Installing an Everhard septic system needs careful planning, site assessment and council compliance checks to ensure long-term, reliable performance and environmental safety. These septic tanks are specifically designed for Queensland and Australia's harsh conditions, but proper installation is essential to avoiding future issues like poor drainage, system overload or complete system breakdowns.
Our team of experienced plumbers starts by assessing your property, soil type and figuring out what size tank will suit your lifestyle, budget and water usage. Before we install your Everhard septic tank, we must get approval from your local council to ensure that it complies with wastewater regulations and Australian standards.
Our septic tank installers specialise in installing Everhard septic tanks on a range of different properties around South East Queensland, including:
Once installed correctly, Everhard septic tanks provide reliable, low-maintenance wastewater treatment for years and even decades to come.

Choosing the right size of the Everhard septic tank is essential. The correct size depends on a number of factors, including the number of people living in your house, daily water usage and the conditions of your property. Installing the wrong size can lead to your septic tank overflowing, foul odours and system failures.
As a general rule of thumb, small households suit a 2500L tank, average homes need a 3000L tank and larger homes or commercial sites need a 4000L tank. However, before choosing your Everhard plastic septic tank, it's always a good idea to check with one of our expert septic installers.
Investing in routine maintenance is an important step in keeping your Everhard septic system operating smoothly. Our maintenance services include inspecting your septic system from top to bottom, checking the inlets and outlet components and assessing the sludge and effluent levels within the tank.
Most Everhard septic systems need to be pumped out every 3 - 5 years, depending on the size of the tank and household. Larger homes or homes that use a lot of water may need more frequent pump-outs. Regular pump outs and maintenance help remove accumulated sludge and scum from the bottom of your septic tank and prevent blockages.

Everhard has more than 20 years of experience in the manufacturing and distribution of polymer septic tanks. One of Everhard’s two main septic tank types, they’re constructed from top-grade virgin polypropylene.
The polypropylene material renders the septic tanks resistant to the negative effects of moisture and corrosion. Everhard’s polymer tanks are completely recyclable and are capable of lasting over a span of multiple decades.
In addition to the aforementioned benefits, the polymer holds added protection against harmful ultraviolet lights; further adding to its durability.
Light in weight, Everhard’s polymer septic tanks offer excellent advantages in terms of transportation, and ease of handling. Considering their manoeuvrability, installation of these tanks can be readily performed by a licensed drainage professional.
These polymer tanks fully meet the AS/NZS 1546.1-2008 requirements for on-site domestic wastewater treatments. And coming with a 15-year manufacturer’s guarantee, you can rest assured that your tank is built to last.

As well as polymer, Everhard has a steel-reinforced, pre-cast septic tank design as an alternative to plastic models. Produced in rigid moulds, the concrete septic tanks are excellent in quality, and offer dimension stability.
These septic tanks are manufactured in strict accordance with Australian industry standards, including the Standards Mark symbol for reliability, quality assurance and safety.
Certain local and state authorities require that tanks have internal partition dividing. Many of Everhard’s tanks are available with this. Also, approved injection-moulded polymer inlet and outlet baffles are fitted in tanks, with polymer access and sealed collar inspection covers being standard features.
Everhard’s pre-cast concrete tanks are designed specifically for domestic wastewater treatment, so the attention paid to industry-standard requirements is of the highest level.
