    Clivus Multrum™ waterless sanitation for homes, public facilities and commercial sites

    Born from a desire to conserve the environment and keep waterways clean, Clivus Multrum™ is one of the world’s leading brands in waterless sanitation.

    A porcelain pedestal connects by chute to an underfloor composting chamber, where aerobic decomposition turns human waste into a nutrient-rich, soil-like end product over time.

    Clivus Multrum™ offers systems and sizes for residential through to commercial use, with batching and continuous models designed for low maintenance and the advantages of long-retention composting.

    The range is suitable for off-grid homes, baches, eco-residences and remote cabins, as well as lodges, glamping sites, marae, alpine huts, walking tracks, visitor centres, campgrounds, council facilities and DOC-style sites.
