Frequently Asked Questions

Below are some commonly asked questions that you might find helpful in addressing any queries you have.


Home Sewage Treatment

What is a Home Sewage Treatment Plant (HSTP)?

A Home Sewage Treatment Plant (HSTP) is similar to a Municipal Sewage Treatment Works, except that it is designed to fit in your own back yard. A HSTP uses all the same proven treatment methods as the larger municipal systems to treat all your home’s wastewater, that’s everything that flows from your toilets, showers/baths, washing machines etc. A HSTP treats and disinfects the homes wastewater to such a high degree that the water is able to be reused on your lawn for irrigation purposes. Most people would not realise that a home has its own HSTP because they are low maintenance (Taylex systems only need to be serviced quarterly) and function the same as a typical mains/municipal sewer connection, 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systems have been used to treat wastewater for hundreds of years, but their treatment methods/results are largely outdated by today’s standards. Septic tanks have no aerobic or equivalent advanced secondary treatment methods and only treat wastewater 20% of what is required to ensure it is harmless to the environment. Meaning the wider environment is responsible for the remaining 80% of treatment putting it under unnecessary strain.

Additionally septic tanks are only designed to treat the homes black-water (sewage) meaning you will need to install additional separate grey-water and grease trap tanks, whereas a Taylex system offers a 1 tank solution.

In applications where the system will go for prolonged periods with no use at all (e.g. remote Country Fire Authority/fire brigade depots) a septic tank may prove to be the most effective option and Taylex do make systems for these situations, however for 95% of applications Advanced Secondary Wastewater treatment systems are the best option.

What is a worm farm?

A worm farm is a method of sewage treatment that is carried out by the action of worms that live in the sewage treatment plant and produces results that are classified in the same way as septic tanks. As the treatment is relying solely on the worms for the treatment, if the worms are killed due to surge loading, exposure to harsh chemicals etc, the worms will die impacting the effectiveness of the systems treatment process.

The homeowner is required to clean any sediment from inside the distribution pit, wearing protective gloves and bury 200mm below ground. Because the treatment method only partly removes the pollutants, the water pumped from the system must be discharged at least 200mm below ground in a trench system (Victorian EPA Requirement), identical to the requirements throughout Australia for Septic Tank Systems.

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 to 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. Because the sand acts as a mechanical filter for non-treatable matter, the septic tank must be pumped regularly to ensure solids flushed out of the septic tank do not block the sand media.

The sand media cannot be backwashed or cleaned and must be removed and replaced by fresh sand at the end of the life of the sand media. In poorly designed or constructed systems, failure can occur in as little as 3 years or less. leading to the need to dig out the sand with a machine, load it into trucks, transport it to a noxious disposal site and bring back in 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 the national standards and are certified in all Australian states and territories. So why have both options available if they essentially do the same thing?

Our concrete ABS Systems are suited to 90% of all domestic installations. Taylex Polymer Tanks are designed to accommodate site conditions where it is not possible to crane in a concrete treatment system e.g. steep terrain. Our unique polymer mould cleverly uses ‘Sandwich closed-cell foam polymer’ to mould the compartment walls in one piece. There are no joins or glued-in compartments and all partitions extend to the lid of the tank, so you can enjoy the same peace of mind as if you had a Taylex concrete system.


Do systems need to be serviced?


All Taylex Wastewater treatment systems are required to be serviced quarterly as a condition of their State Accreditation Approval and may only be serviced by licensed wastewater service personnel. To get in touch with your local accredited Taylex service agent click here.

Who can Service a Treatment Plant? Why do they need to be serviced?

Only registered, licensed wastewater service personnel can service Wastewater treatment systems, as specified by Australian & state law. However, there are better reasons to get your system serviced than meeting council requirements.

Getting your system serviced regularly ensures that you Taylex is always operating at peak efficiency, producing high quality water for reuse on your yard & garden. Additionally, if you are getting your system serviced with an accredited Taylex service agent, you will receive an extended warranty on all electrical components for complete peace of mind for the ongoing health of your system. To get in touch with your local Taylex service agent click here.

How can I help my service agent? To help your Service agent conduct their job effectively always maintain clear access to and around your system, keep grass mowed and tidy and keep the top of your system clear and free of any obstacles. If safe access to your system is not provided your service tech may have to reschedule until the issues are remedied.

What happens if I don't have power?

A generator can be connected to the pump lead, allowing the effluent to be pumped out and enabling you, the homeowner, to use the system.

How long will my system run without power?

Bacteria can survive a short time without air. When the power is restored, there might be a bad smell, but it will dissipate when the air returns.

Customer Service

How much power does a system use? Are Taylex Systems solar ready?

The cost of power is becoming a huge issue in our society.

At Taylex we realise that we must find cheaper ways to run our systems without compromising the performance of the system. So we have developed the Taylex™ ABS (Advanced Blower System) which can turn some parts of the system off to conserve power if the usage of the system will permit.

It is impossible for Taylex or any other treatment plant company to give our customers an exact cost of how much the operating costs of a treatment system will be each year. The reason we can’t is because the submersible pump that pumps to the irrigation fields is the biggest consumer of power. Depending on how many people live in the house and how much water each person uses will materially alter how often and how long the pump will run for. See attached document.

All Taylex Wastewater Treatment Systems can be powered by your home’s solar system please consult with your local service technician/specialist on best practices. Click here to download the relevant datasheets.

Can I upgrade my existing Taylex Compact or Taylex Clearwater 90 Deluxe to a new energy efficient blower?

Absolutely! We are continually looking for new ways to improve the treatment and energy efficiency of our systems. We offer a “Retro Upgrade kit” that is compatible with all older Taylex models to ensure your system is running at peak efficiency. Enquire with us to organise one for your system. Please note that the Retro upgrade kit will need to be installed by a licensed professional.

What cleaning products can I safely use?

Taylex Wastewater Treatment Systems utilize naturally occurring “Aerobic” bacteria to treat your homes wastewater, therefore harsh chemicals and antibacterial can harm and kill these beneficial Aerobic bacteria, if they are used in large quantities. Taylex recommends that you choose products with some of the following characteristics:

    • “Septic Safe”
    • Biodegradable
    • Doesn’t contain bleach, chlorine or strong antibacterial agents

Taylex systems are robust by design and can handle small quantities of harmful substances, but moderation is key when it comes to anything that goes down your drain.

Can I reuse the water from a domestic Home Sewage Treatment Plant back inside my home?

No, current legislation prevents the internal reuse of water from Wastewater treatment systems. It is our belief at Taylex that due to the high-risk factors (unforeseen equipment failure, inadequate/irregular servicing, surge flows, etc.) involved with facilitating this outweigh the limited benefits.

Can I use a garbage disposal unit?


Putting kitchen/food scraps directly into your system will put an added strain onto your system and introduce extra levels of nitrogen & phosphorus, additional the food scraps will start to decompose resulting in bad smells. Best practise is to dispose of food waste straight into the garbage bin for collection or a compost bin.

How noisy is the Air Blower?

Taylex systems use quiet, energy efficient Nitto blowers, unless you are standing directly over the system you should not be able to hear it. If you do hear loud noises coming from your system, there may be something wrong and should contact your local service technician.

Can I turn the system off when I go on holidays?


Just as you don’t turn off the aerator in the gold fish bowl or turn the power off to the refrigerator or freezer, you do not turn the power off to the Secondary Wastewater Treatment System. The bacteria are naturally regulating in numbers, so, when no more food matter is introduced from the home, they will slowly die off so their numbers will be controlled by the remaining available food.

They will still have oxygen and a small number will remain viable and quickly multiply back up to previous levels as soon as a fresh food source is introduced on your return. If you turn the power off, they will all begin dying within 8 hours as they will use up all the available dissolved oxygen and the plant will turn anaerobic killing all aerobic bacteria. It will be very difficult to re-establish a healthy biomass when you turn the plant back on and it will smell badly for a long time. You may even have to pump the system out and start it up all over again.

Can I have a Spa Bath?


Spa baths generally hold a relatively large volume of water that is only lightly polluted by body oil, soaps, etc. However because there is a high hydraulic (water) loading, be cautious not to surge your system with water.

Can I cover the top of the System?


Free, unrestricted access must be provided to all access points on the top of the system at all times. This is because we need to comply with Occupational Work Health and Safety Requirements in providing a Safe Workplace for our service technicians.
