Frequently Asked Questions

  • How does a Clivus Multrum work?

    Clivus Multrum is a composting toilet. The sewage in a Clivus Multrum is composted over a long period of time, with the help of micro-organisms, ventilation and humidity. The process takes several years. Please find more information on “Technology”.

  • What is the difference between a Clivus Multrum and a small environmental toilet?

    The Clivus Multrum tank has a large capacity in which the sewage is completely composted. This takes about 6 years. A smaller toilet does not have enough volume for complete composting. The sewage must be removed regularly and disposed of appropriately (not directly in the environment).

  • For whom is Clivus Multrum a suitable solution?

    Clivus Multrum is suitable where water is not available or in short supply, or when no traditional sewage grid has reached. Clivus Multrum is a perfect alternative for those who want to save thousands of liters of water.
