Clivus Multrum™ Maintenance Instructions

Like any toilet, a Clivus Multrum™ benefits from simple, regular care so it performs at its best for years to come.

Daily User Interactions

After each solid deposit, add one scoop of bulking agent to the chamber—“scoop per poop.” No other daily action is required.

Weekly Maintenance

Clean the pedestal and bowl with the a compost-safe enzymatic cleaner, wiping the seat, lid, and internal surfaces as needed.

If you have a batching system with mixers, rotate the mixer to blend fresh material with older compost, spread active bacteria, introduce air, and level the surface to create more usable space in the chamber.

Monthly Maintenance

For continuous systems, rake the pile to topple the cone and redistribute compost across the chamber so the top layer stays flat and ready for the next month of use.

Regular Maintenance

Manage capacity by removing finished compost only when necessary.

For batching systems, change out a chamber when it is about three-quarters full, then start a new batch following the start-up steps.

For continuous systems, empty the designated removal area of the chamber only, and leave the fresher compost undisturbed.

Annual Scheduled Servicing (Technical System Requirements)

Once a year, check the vent system for obstructions, clean the fan, and confirm steady airflow.

Flush the leachate drain line to clear any debris.

If your installation uses a zero-discharge recirculation kit, inspect and/or service the pump and float switch annually to ensure reliable operation.

For Commercial Operations

WCTNZ® can help you develop a site-specific maintenance schedule for lodges, walking treks, council public toilets, and other facilities. Routine tasks can be performed entirely by the site operator; patrons do not need to add bulking agent. Operators may dose larger amounts of bulking agent on a regular basis—for example, weekly—and follow a simple plan indicating when to add microbes, when to topple and level the pile, and when to empty or rotate batches. This approach keeps visitor interactions minimal while maintaining consistent performance.
