The Baloo Bush Retreat - Case Study

Nestled amongst the bushlands of Woollamia, one of our customers Harry has created a small eco getaway called The Baloo Bush Retreat. Specifically designed as a couples retreat, the space boasts an epic outdoor shower, a portable tiny house, a roofed outdoor kitchen and a Nature Loo composting toilet, with other features such as swinging beds in the trees.

There were many reasons why Harry opted for the composting toilet:-

  • The cost both economically and environmentally far outweighed conventional systems.
  • The ease of simply installing the cedar house and toilet and it’s done.
  • No need for water, piping, plumbers, etc.
  • No need for council approval (in my area), and
  • The environmentally conscious and awareness message that the toilet sends to all clients of the retreat.

The initial reaction from clients was amazement! Clients often came to the retreat thinking that the composting toilet may smell, but were amazed to see that the toilet doesn’t smell at all. If anything the toilet had now become an asset to the retreat.

Harry says he would most definitely recommend a composting toilet to others. They are literally so easy, better for the environment, cheap and they don’t smell.


How to build a self-sustaining home - Case Study

Customer: Stuart E. NSW

Product: Classic 850

Project: Build a self-sustaining home

The 100 m2 home with two bathrooms, designed for two plus guests, was built on the Sunshine Coast by Direct Portable Buildings and delivered to site on the northern coast of NSW on the back of a couple of trucks.

The location of the cabin’s site was chosen based on accommodating the waterless toilet tanks beneath the home. One of the bathrooms was well located for installing and servicing the loos. We went with the lower cost batch process Nature Loo 850 with aerator option. The other was in an awkward position with inadequate space to stand, surrounded by large rocks and 20 metres to drag a full bin when full. Whilst there would have been enough room to install the Nature Loo Classic 850, it would have required a lot of effort to service the bins. There were too many obstacles in the way; rocks and pillars and beams. We installed the continuous process Clivus Multrum CM10. Both toilets are working well.

How about maintenance and how often do the bins need to be emptied? 
We rotated the first 850 compost bin after a year, but we could have left it several more months more. Whilst the bin was not too heavy I am glad I did not have to manoeuvre it over rocky or hilly ground although the wheels certainly aided the process. 
The CM10 has not needed emptying yet. We have just raked the surface to level the pyramid effect under the pedestal and added some water.

What else did we do to save water? 
We managed to persuade our local geotechnical engineer to push through council the approval of the grease trap and Ecoflo GWS10 sand filter. This despite it not being approved by the NSW Government on account of there being no septic tank! Some geotechs and councils will approve the GWS10 despite a lack of state approval. The 300L grease trap is collecting grease but there is still no need to pump it out. 
The GWS10 looks just like a tank full of occasionally moist pine bark. To minimise grease build up we wipe plates with the paper towel before washing them. 
We installed water tanks with a capacity of 35000L (plus 20000L for the rural fire service). In Summer it was not enough. We had to call on reinforcements at a cost of $280 per 18000L delivery. This makes me glad we installed the waterless loos to save on our water consumption.



Nature Loo / Ecoflo was the first supplier of composting toilets to be certified to New Zealand and Australian Standard 1546.2
