          SKU: CM-HP-2
          The Clivus Multrum™ - CM HP system is designing to meet the larger capacity requirement of a few users to a family unit with a chamber (tank) underfloor-clearance requirement of 750 mm

          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.

          If your user rating is higher than the capacity of the system choose additional chambers.

          Choose additional chambers to increase the capacity of your system or to provide longer composting times where needed.

          Choose additional heating to speed up or maintain the composting process or for colder climates (100watts @ 12 Volts DC)

          For direct solar-powered options Use one 150 Watt Solar Panel (PV) with a 10amp Solar Controller. Use an on-off switch when heating is not desired.

          Use a 150 Watt transformer (240 Volt AC to 12 Volt DC) supply to power your Heating Element Option

          Use a 150 Watt transformer (240 Volt AC to 12 Volt DC) supply to power your Heating Element Option

          If the underfloor height exceeds 1200mm (floor-to-floor), you will require additional lengths of the chute.


          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.

          Vent stack kit for installation.

          In residential applications, a vertical vent must extend 0.6m above the roofline - this is a code requirement.

          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.

          Required for adaption to smaller vent pipes.

          Note: systems with 50mm piping will require a mounting stay (not supplied).

          Extend your drain pipe to reach your soak pit/trench.

          The system is packed with 1 meter of 25mm leachate drain pipe as a standard.

          Most soakaways should be installed 3 meters away from the foundations of the structure but this remains circumstantial to the site.

          Run your leachate drain into a soak pit (vertical soak-away) or into a trench (horizontal soak-away).
