Clivus Multrum™ | CM40 Next-Gen (Custom Package)

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.

Please select the second pedestal (toilet fixture) option you would like to accompany your composting system. Optional (Leave NIL if you would only purchase a single pedestal for this system).

Choose toilet colour

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.

Use two fans if connecting two or more pedestals (toilet fixtures) to one CM tank.

Dual fan installation options:

Series - single vent stack with two fan units installed in-line

Parallel - dual vent stack with one fan unit per vent stack (recommended)

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

Note: if more than two pedestals are connected to one CM tank, fan unit wattage must be higher than 5w.

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
