LIMITED WATER TREATMENT

Septic Failure

Why Your Wastewater System Matters A failing septic system puts your family, pets and local environment at risk — from dangerous pathogens to contaminated water sources. Getting it right matters.

Why Taylex? Built using single-piece moulding technology, Taylex systems are stronger and longer-lasting than traditional septic tanks. With a 99.99% bacterial disinfection rate, they treat wastewater to a far higher standard — protecting your family and the environment for years to come. You may have a failing septic system, without even realising. Common signs include:

Foul odour coming from your system or parts of your yard.
Constant wet or spongy patches in the yard (that are not due to rain or other water source).
Gurgling/strange noises after using plumbing appliances i.e toilets.
Unexplained slow drainage from sinks, showers, baths, etc.

FAQs

What is a Home Sewage Treatment Plant (HSTP)?

A Home Sewage Treatment Plant (HSTP) operates similarly to a Municipal Sewage Treatment Works but is designed to fit in your backyard. It uses the same proven treatment methods as larger municipal systems to process all your home’s wastewater, including water from toilets, showers, baths, washing machines, and more. The HSTP treats and disinfects this wastewater to such a high standard that the water can be safely reused for irrigation purposes on your lawn. Most people don’t realise a home has its own HSTP, as these systems are low-maintenance and function in the same way as a typical mains or municipal sewer connection – except with the added benefit of being able to reuse your water.

What is a Septic Tank?

Septic systems have been used to treat wastewater for centuries, but their treatment methods and results are now outdated by modern standards. Traditional septic tanks lack aerobic or equivalent advanced secondary treatment processes, treating only about 20% of the wastewater necessary to make it environmentally safe. This leaves the remaining 80% of treatment to the environment, placing unnecessary strain on natural systems.

Furthermore, septic tanks are designed only to treat a home’s black water (sewage), meaning additional separate tanks for grey water and grease traps are required. In contrast, a Taylex system provides a convenient one-tank solution.

In certain applications, such as remote Country Fire Authority or fire brigade depots, where the system may be unused for extended periods, a septic tank might be the most effective option. Taylex also offers systems designed for these specific situations. However, for 95% of applications, advanced secondary wastewater treatment systems are the optimal choice.

What is a worm farm?

Worm-farm wastewater systems use worms and natural filtration to treat sewage in an aerobic environment. Some models are certified to Australian Standards as secondary treatment systems.

While they can reduce the need for regular pump-outs, they rely heavily on maintaining the right conditions for the worms to survive. Extended periods of low use, overloading, or harsh chemicals can affect performance. These systems still require servicing every few years, and performance depends on proper installation and consistent care.

What is a sand filter?

A sand filter is an additional treatment process fitted to a Septic Tank outlet to process the partially treated effluent from the Septic Tank. Because the All-Waste Septic Tank is incapable of reducing the pollution level in the sewage and sullage that discharges from the home to a level that is safe for humans and the environment, a sand filter is constructed behind the septic tank to receive all the still heavily polluted effluent. The correct grading and placement of the sand, placement of the distribution and under-drains, etc., can greatly affect the successful operation and operating life of the Septic Tank Sand Filter System.

As the sand acts as a mechanical filter for non-treatable matter, the septic tank must be regularly pumped to prevent solids from clogging the sand media. The sand media itself cannot be backwashed or cleaned; it must be removed and replaced with fresh sand at the end of its lifespan. In systems that are poorly designed or constructed, failure can occur within as little as three years, necessitating the removal of the sand by machine, transport to a noxious disposal site, and the replacement with several truckloads of fresh sand.

Concrete or Poly? What is the difference?

Both the Taylex concrete and lightweight wastewater treatment systems are six-stage aerated wastewater treatment systems that exceed national standards and are certified across all Australian states and territories. So why offer both options if they essentially perform the same function?

Our concrete ABS systems are suitable for 90% of domestic installations. Taylex polymer tanks, on the other hand, are designed for sites where it’s not feasible to crane in a concrete treatment system, such as in areas with steep terrain. Our unique polymer mould uses ‘sandwich closed-cell foam polymer’ to form the compartment walls in a single piece. There are no joins or glued-in compartments, and all partitions extend up to the lid of the tank, giving you the same peace of mind as a Taylex concrete system.
