Why buy a waterless composting toilet?
To Save Water
Each year a typical home contaminates and flushes 35,000 litres of drinking water down the toilet and into sewers. Ecoflo composting toilets do not need water, conserving this precious resource and saving you money in the process.
To Save Money
Our composting toilets and primary treatment grey water systems have minimal electrical costs, few moving parts, no pumps and do not require service or maintenance contracts. When compared to other wastewater management systems (such as aerated wastewater treatment systems) this represents an ongoing annual saving of $500 - $1,000 and is on top of the savings from a significantly lower initial investment and the opportunity to install lower capacity water tanks.
To Be Self-Sufficient
With a waterless composting toilet, greywater system, rainwater tank, compost pile, urine collection and solar system your house and garden can be entirely self-sufficient when it comes to water, waste management, fertiliser and energy.
To Add Value to Your Home
Just as water tanks add value to your home, so do waterless composting toilets, as we all strive to minimise water consumption and conserve resources.

For Environmental Benefits
Waste from flushing toilet systems attached to on-site wastewater treatment plants is normally treated with harmful chemicals for disinfection and consume so much energy in aerating and pumping that normal domestic solar power systems cannot handle the load. Ecoflo’s waterless composting toilets use a natural biological process, are environmentally-friendly and help return nutrients to the soil. Most systems consume minimal electrical power.
What do they look like?
Do they smell?
There is absolutely no odour in a bathroom containing an Ecoflo waterless composting toilet. There is actually less odour than you encounter with a normal flushing toilet. The reason for this is that all Ecoflo systems use low-wattage ventilation systems to draw toilet odours down the pedestal, through the composting chambers, and out an external vent pipe above your dwelling, leaving your toilet room completely odourless – no need for deodorizers!
Can I install one myself?
Yes. Someone with basic handyman (or handywoman) experience can install a Nature Loo or Sun-Mar waterless composting toilet in about half a day. Depending on which state the toilet is to be installed in, a registered plumber may have to sign off on the finished installation. A registered plumber should be used from the start if you are installing:
- The Sun-Mar microflush toilets (Centrex 2000 and 3000 models) as this is more complicated than the 100% waterless toilets.
- A pump well for the GWS10 grey water treatment system if the site does not have a favourable slope allowing the water to drain under gravity
- An advanced secondary grey water treatment system.
Ensure you follow the installation instruction manuals provided and if required do not hesitate to call our customer support on 1300 138 182.
How do Ecoflo’s composting toilet systems work?
Ecoflo's waterless composting toilets offer a hygienic way to recycle human waste in a manner that avoids polluting and wasting precious water. Our Nature Loo models rely on a ‘batch composting process’ while our Sun-Mar models use a combination of a ‘batch’ and ‘continuous composting process’.
All of our systems are designed to ensure the correct levels of moisture, temperature, oxygen, carbon and nitrogen required to achieve good composting are present in the chambers. Moisture is managed through drainage and evaporation systems which remove excess liquid from the solids. Oxygen is regulated using low-wattage ventilation systems which aerate the compost and also serve to evacuate any odours from the toilet room. The ideal temperature is achieved through exposure of the black Nature Loo chambers to sunlight and the use of heating elements for Sun-Mar systems. The carbon/nitrogen balance is managed by regularly adding carbon-dense mulch to the pile. At the end of the composting process microbes have broken down the waste into humus, a soil-like substance with an earthy odour.
How do composting toilets differ from other systems?
There are a number of alternative on-site domestic wastewater treatment systems that use non-composting technology to deal with household waste, such as worm farm systems, septic systems and aerated wastewater treatment systems.
The table below outlines a few reasons why composting toilets are better for your back pocket and the environment.
|Worm Farms and AWTS/ATU Treatment Systems||Composting Toilet with a Greywater Treatment System|
|Waste 35,000 litres of water per year per household||Uses none and wastes none|
|2-3 times more expensive to purchase||Relatively inexpensive to purchase|
|Expensive servicing by the third party (prices vary greatly depending on location)||Inexpensive self-servicing|
|Certified by state health depts. as not being health hazard||Certified by state health depts. as not being the health hazard|
|Toilet odours linger||All odours immediately and constantly drawn away by a fan|
|Black and grey water treated||Black and grey water treated|
|Flush toilet with unnecessary water-wasting cistern||Attractive and easy-to-clean pedestal designed to avoid soiling|
The following table compares the cost of an Ecoflo waterless composting toilet and separate greywater system against other systems. The table is offered only as a guide. Installation costs differ widely depending on local site conditions.
|System||Equipment and Installation Cost||Ongoing Cost*|
|Waterless composting toilet with primary grey water treatment||$6,000 – $7,000||Extremely low|
|Septic Tank||$7,000 – $10,000||Low|
|Septic Tank with large sand filter or reed bed||$12,000 - $15,000||Low|
|Aerated water treatment system||$12,000 - $18,000||$500-1,000 per year|
|Worm farm system||$12,000 - $18,000||$500 per year|
*Includes council mandated service contracts, electricity, replacement pumps and council fees.
How do I manage my greywater?
A composting toilet only handles your solid waste, also known as black water. The grey water produced by your shower, bath, basins, laundry and kitchen sink can be treated to primary or secondary standard.
More information specifically on how to manage your greywater can be found under the Greywater FAQs page.
My council won’t approve a composting toilet. What can I do?
You are free to make your own decision regarding the type of treatment system you want to have. If you intend to obtain council approval for your new home you will need to submit a development application. Part of this will involve the treatment of your black and grey water. The council should approve your chosen system provided that the system is state government approved and the site is suitable. In rare cases, issues can arise with any system, however, expensive and elaborate, depending on soil type, a size of block and proximity to watercourses and bores. However, in principle, the council does not have the right to object to a composting toilet based system as long as it is state approved.
We regularly hear of councils trying to persuade people to install aerated water treatment systems (AWTS), rather than a composting toilet and separate grey water treatment. We understand that this is because councils collect fees from homes with an AWTS but are not able to do so with homes with composting toilets. The plumbing officer may also not understand the importance to the non-urbanised community of water self-sufficiency and the benefit to your land of the end product of a composting toilet. Nor is the council concerned about the energy consumption of an AWTS (two electrical pumps) and the chlorinated water that ends up on your land. This is particularly important for off-grid properties. Councils quote the average annual maintenance cost of an AWTS is $800 (chemicals, electricity, replacing worn out parts and servicing).
Should your council prevent you from installing a state approved composting toilet we will happily talk to the relevant council department on your behalf. We also have a list of Geotech engineers who are happy to incorporate composting toilets in your plans. Some geotechs are in the pockets of AWTS suppliers and will attempt to persuade you to buy an AWTS, so please research your Geotech thoroughly before engaging in their services.
Is an Ecoflo composting toilet right for me?
If the location where you want to install a waterless composting toilet can be connected to a town sewerage system, chances are your local council will insist that you connect to it.
However, as of 2007 some metropolitan city councils are beginning to understand the significant role waterless composting toilets can play in water conservation and are beginning to allow their use in sewered areas.
We suggest you contact your council plumbing officer and question them about this. There is no single more effective way to reduce your water consumption than to stop flushing water down the toilet. If the response is unsatisfactory, speak to their supervisor or give us a call.
Of course, not all of our customers feel compelled to discuss their toilet arrangements with the council! Many waterless composting toilets are installed without referral to a council authority.
