Description
Certified to Australian/New Zealand Standards 1546.2:2008 
This system come with at least two composting chambers. Fill one, put it aside to continue composting, and put the second chamber into use. When it’s time to change chambers again, the contents of the first chamber should be well and truly composted. You then remove the compost, put it on your garden or bury it, and re-use the chamber.
If usage increases, an additional chamber can be purchased to accommodate faster rotation and still provide adequate composting time. Go to our “How They Work” page to find out more.
Included in the Nature Loo Classic 850 Toilet Package is:
- Minimum 2 x composting chambers
- Waste connecting chute (55cm in length as standard) Additional lengths can be purchased if required
- Ventilation system including a 12 volt 5 watt fan in housing and transformer*
- Nature Quick Microbe starter bag
- 1 x 125ml Nature Flush Enzymes & spray bottle
- Bulking agent
- Easy to follow DIY Installation and Maintenance manuals
* If the transformer is not required, it will be replaced with a spare fan.
Due to freight costs only additional 100mm PVC pipe and gravel for the 2m long x 40cm wide x 40cm deep liquid absorption trench will need to be purchased locally.
Maintenance
Every few months to a year the Nature-Loo composting toilet chambers will need to be rotated/exchanged. No official training is required to carry out the rotation.
If the toilet is used consistently by the same number of people, you will soon see how often the ‘In-Service’ chamber needs to be replaced as this is dependent on use.
You can purchase any number of compost chambers in a package but the minimum is two (e.g. Classic 850-2). You can either upgrade to the three chamber model (e.g. Classic 850-3) when you first purchase the system or buy a third chamber at a later date.
A sufficient number of chambers must be purchased to allow the out-of-service chamber a minimum time (5 months for the Classic 850) from the time they are disconnected from the waste chute.
Every few weeks you should shine a torch down the toilet pedestal to see if it is full, (when the compost pile reaches the top of the internal vent pipes). This is not as bad as it sounds since the pile will always be covered with sugar cane mulch and toilet paper.
When the ‘In-Service’ chamber is full, you will need to swap it with the ‘Out-of-Service’ chamber.
To exchange the chambers:
- Disconnect the chamber(s) from the liquid drain and ventilation pipe
- The compost pile in the Out-of-Service chamber should have reduced in size to about 20% of its original size and contain a maximum of 75% moisture. This ‘humus’ must then be disposed of as per the local health department regulations. This normally means placing the humus under 10cm of soil or other plant based compost.
- Unscrew the flexible vent pipe from the compost chamber
- Close the liquid drain valve and disconnect it from the base of the chamber.
- Unstrap the lid of the chamber and lift it up the waste chute.
- Slide or roll the chamber on the trolley to one side and immediately put on the lid from the emptied Out-of-Service chamber. The lid contains an insect-screened air intake cap to allow circulation to continue.
- Depending on the model this full chamber is either connected up to the liquid drain and ventilation system beside the In-Service chamber or is capped with insect-meshed breathers and left in an airy and sunny spot on the property to compost.
- The empty chamber can then be placed into position under the toilet pedestal, the chamber lid lowered and the flexible vent pipe and liquid drain hose reconnected leaving the liquid drain valve in the open position
