The dry-flush piston removes waste without using clean water.
Minimal upkeep by design.
A single moving part and a sealed containment tank keep operation simple and dependable.
HOW THE SOLARID TOILET WORKS
Where does the waste go?
The toilet moves waste out of the bowl and into a separate containment system. Your site determines how that waste is stored and serviced.
1 Press the foot pedal
The pedal starts the powered flush cycle.
2 The piston moves waste
A piston transfers waste through the chute without flush water.
3 Waste stays outside the bowl
A holding tank or compatible composting setup receives the waste for later servicing.
INSTALLATION OF SOLARID TOILET
Look beneath the floor.
Plan space for the flush mechanism and waste chute, a compatible containment system, a power source, and access for servicing.
The right configuration and project investment depend on your installation.
Install support for your site
Solarid provides install support based on what your site needs.
SITE APPLICATIONS
Could Solarid fit your site?
Start with the way your space will be used. Then plan the toilet, power source, and waste containment together.

SOLARID TOILET MODELS
Plan the system for your project.
Choose the Solarid Toilet model and containment setup around your available space and intended use. The toilet can be installed in existing sites or incorporated into a new build.
Solarid Toilet features a 12-inch waste chute and a foot pedal that activates the waterless flush. Waste moves into a separate holding tank or compatible composting system. Built-in usage monitoring and a backup battery support everyday operation.
Shipping not included.
The same waterless flush technology with a longer, 24-inch waste chute for installations that need an extended configuration. A foot pedal activates the flush, transferring waste into a separate holding tank or compatible composting system. The Extended model includes built-in usage monitoring and a backup battery.
Shipping not included.

FAQs
-
The main difference is how waste is moved. Traditional flush toilets use water to push waste away, while the Solarid Toilet uses a mechanical piston to do the job without any water.
This approach results in a lower environmental footprint and significantly reduces upfront costs because it eliminates the need for a septic tank or leach field.
-
The Solarid Toilet and incinerator toilet work very differently. An incinerator toilet burns waste into ash, which requires significant energy and has higher operating costs.
In contrast, the Solarid Toilet uses a mechanical flush system to move waste into a pit, chamber, or tank, with much lower energy use, fewer moving parts, and lower overall operating costs.
-
While the Solarid Toilet is more forgiving than a standard flush toilet, it’s best to follow the same rules about what can be flushed.
To keep the system running smoothly and avoid clogs:
Do not flush items that could clog the pump truck’s hose, such as diapers, cans, bottles, or other bulky objects.
Avoid flushing dirt, sand, or gritty materials, as these can get trapped between the piston head and the waste chute, potentially causing damage.
-
No, the Solarid Toilet is designed to be odor-free.
Once flushed, the system completely seals the bathroom from the waste tank, which has its built-in exhaust system to manage odors at the source.
