The Nature Loo pedestals are designed to avoid soiling and actually requires less cleaning than a flushing toilet. Unlike flushing toilets that must first catch the waste before flushing it away, the Nature Loo waterless pedestals have tested fall lines to avoid messing the sides. We know that strange things can happen so the toilet is supplied with a bottle of Nature Flush enzyme concentrate and a spray bottle.
Any Cleaning? Not as much as you’d think
Nature Flush has a delicious vanilla fragrance and is diluted with 19 parts water and used as a natural cleaner. The spray by itself can do the job but a standard toilet brush can also be used with the spray. The enzymes will also accelerate the composting process a catalyst and initiator in chemical reactions. Refills of the enzyme concentrate can be purchased online.
Adding bulking agent – Less effort than flushing
The bulking agent should be added on a regular basis, preferably a handful after each #2. Alternatively, add the equivalent of this on a daily or weekly basis. Nothing is added if you are only doing a #1. The bulking agent can be added through the pedestal so rather than pushing a flush button you drop a handful of the bulking agent into the pedestal bowl. The bulking agent is supplied as a sample with the toilet. The sample is the right grade sugar cane mulch (not too fine).
If you cannot find sugarcane locally we recommend finely chopped up chaff or wood shavings (not sawdust and not cedar, eucalypt or cypress). Dried leaves can also be used but not those from a eucalyptus tree as the oils in the leaves have antimicrobial properties.
Rotating/Exchanging the Compost Treatment Chambers
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 and can be carried out by the owner of the property, a handyman, plumber etc.
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 750-2). You can either upgrade to the three chamber model (e.g. Classic 750-3) 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 750 and 6 months for the Classic 1000) 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 drains 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
