    Choose the Product options below

    *

    Please select the primary pedestal (toilet fixture) option you would like to accompany your composting system.

    Note; that the Urine-Diversion (UD) pedestal option is most suitable where there is high use in peek or large family gatherings.

    Note; that with Urine Diversion, it is recommended that the compost mass is kept wet to avoid the pile drying out. Consider getting the hand-held bidet sprayer accessory for facilitating the hydration of compost.

    A hardwearing Nano-Ceramic Non-Stick Coating is applied onto the inner side of the Pedestal (toilet fixture) for maximum cleanliness.

    Note; basic cleaning will still be required.

    Note; non-stick is hydrophobic and repels liquids only.

    *

    Choose the fan voltage to match your power system. (Add additional fan units for replacement parts).

    All ELV (Extra Low Voltage) (12v-48V) are suitable for Off-grid power systems.

    *

    You may need additional vent materials depending on how many storeys your building has.

    Single Storey buildings with a high-profile roof (A frame or mono-pitch) require extra lengths of vent pipe - add one 800mm Vent Pipe Extension

    Double Storey buildings require extra lengths of vent pipe. Please add 4 x 1m Vent Pipe Extensions.

    Double Storey building with a high-profile roof (A frame or mono-pitch) require extra lengths of vent pipe - add one 800mm Vent Pipe Extension

    Kit for stepping the vent stack around the eaves of the roof. Allows you to avoid penetrating the roof.

    Add a wind-driven vent to create redundancy. The wind-driven vent will assist the fan under heavy wind conditions and keep the system going in case of power outage or fan failure.
    Please choose from 2 colours: white or black.

    Select this reducing collar to adapt the wind-driven vent from 150mm to 100mm.

    Choose how you'd like to manage the liquid (leachate) produced by your composting toilet system:

    Discharge to Drain or Trench
    Divert excess leachate to an approved soakage trench, drain field, or dispersal area. This option is suitable for most installations with available drainage capacity and may require a resource consent under the Resource Management Act 1991 (RMA), depending on your local council’s rules.

    Zero Discharge System (Reticulation)
    Select our sealed zero-discharge system to recirculate leachate back into the composting chamber for evaporation or absorption. Since no liquid is discharged to land, water, or air, this option falls outside the scope of the RMA and typically does not require resource consent. Ideal for sensitive environments, remote sites, or areas with strict discharge regulations.

    System sizes with Automatic or Manual reticulation dosing cycle options
    Automatic operations are on timer, and Manual operations are user-operated.

    Small 80L system - Suitable for a light-use system 
    Large 450L system - Suitable for a heavy-use system
