Here are some answers to a lot of the questions people have asked us.

Where can I install my toilet?

  1. Installation in a basement.
  2. Install in a crawl space.
  3. With a pump for the separated fluid, if the installation site is located below the level of the grey water sewer, the pump may be installed in order to pump the fluid to the grey water outlet.
  4. Separate house, pipe length can be as long as you need as long as you stick to the standard of a 75mm gradient per metre. Existing Enviro Toilet systems have reached up to 65m. Keep in mind that the more connectors you make along the pipe the more chance of build up occurring.

What is a “leech field”?

A leech field allows the treated fluids to be evenly dispersed into the ground. for more information on council regulation please visit this website: Auckland City council wastewater PDF

Where can I get more worms?

Worms are Available from Bunnings warehouse, We also collect containers of worms from a local school which will be available soon.

Have these been tested by a local council?

Yes, we have had multiple tests done and have had great results.  Graph of lab results from Rotorua Lakes District Council


Here are some more DO’s and DO NOT’s (these are for BOTH models):

  1. Worms: (Eisenia Foetida – Tiger worms)
    1. Worms can be purchased from worm farms or garden centers all around New Zealand. Order 2000 Tiger worms from your local worm farm or bunnings.
    2. Worms are placed in the main composting chamber within 2 weeks of the toilet being used. Place 2000 worms directly into the composting chamber down through the toilet pan.
  2. Toilet seat.
    1. Keep the toilet seat closed when the toilet is not in use.
    1. “DO NOT” Put cigarette butts or any other burning objects down the toilet. (this has nothing to do with gases; it is to do with the dry toilet paper catching on fire.)
  3. Organic materials
    1. Placing organic materials, such as weeds, grass and leaves (not Oak Leaves) can and will assist with producing good compost and allow variety for the worms. Place approximately one handful per day. If no organic materials are available, add untreated wood shavings or untreated saw dust, i.e. one cup per day.
  4. Kitchen waste
    1. Note if kitchen garbage (waste) is deposited into the toilet it will attract flies, as vegetable matter has fruit fly spores (in most cases) on it and they could hatch and flourish in the composting process.
  5. Inorganic materials
    1. Note “DO NOT” put such materials as glass, metals and plastic into the compost chamber. They will not damage the process but could be hard to retrieve from the compost and could prevent the composting material form moving down the air staircase as it is being processed.
  6. Sanitary towels and nappies.
    1. “DO NOT” Put nappies or sanitary towels into the composting chamber because of their plastic content and their size they will create the same problems as in #5.
  7. Flies
    1. In the early stage of the composting cycle, tiles (like fruit flies) may be found in the composting chamber. This is very unlikely but there can be sometimes be a small amount of spore in the peat moss. If this occurs, it can be rectified easily with organic insecticide or add some untreated fresh sawdust.
  8. Air outlet filter.
    1. The filter that is located just under the air outlet flange needs to be checked and cleaned if required each twelve (12) months.
  9. Fan control.
    1. The current fan is single speed and only needs to be “on” or “off” the current draw is only 1 amp at 12v about 1 quarter of the consumption of a 50-watt bulb! It is best to leave it running all the time.
    2. This can be run by a small solar power pack. (currently being researched)
  10. Cleaning the hygienic chute.
    1. The hygienic chute can be cleaned in the toilet pan, by using a water spray bottle with a mixture of 1-part white vinegar to 6 parts water. Or dish washing liquid. These will not harm the composting process.
    2. The hygienic chute can be removed and washed in a bucket of disinfectant and then washed down with clean water, before replacing the chute.
      “DO NOT” dispose of the disinfectant water down the sink or basin. Dispose of it outside, maybe in the garden.
  11. Compost removal
    1. It is recommended that the compost is removed once every year.
    2. For holiday homes that are only used for 3 months every year, it is recommended that the compost be removed within 3 years.
  12. Removed compost
    1. The compost (humus) is a resource to be used in your garden. It can be put on your vegetable gardens and/or flower gardens. To get the best advantage of the compost dig it into the garden.
  13. Recommendation
    1. To avoid light shining down into the toilet chute place the toilet room light near the front of the room, as this will cast a shadow on the chute.
  14. Failure of power supply.
    1. If the power supply is off for a longer period than 3 days, place GLAD® cling wrap or plastic over the hygienic chute and close the lid over the cover. Remove the wrap/plastic each time the toilet is required for use, repeat this procedure until the power supply is restored. (this is to both stop fumes and any harmful air-born bacteria usually dispersed with the fan.)
  15. Maintaining the fan
    1. Remove the fan every 3 years and clean off any dust that has built up on the fan blades. This can be achieved with ease with the use of an old toothbrush. Once cleaned, refit the fan.
