NPK urinal: waterless urinals for public buildings and collective housing
NPK urinals are waterless urinals designed for urine collection in collective housing and public buildings. Once installed, NPK urinals significantly reduce drinking water consumption. They also facilitate daily maintenance of sanitary facilities. In this way, they actively contribute to the ecological transition of infrastructure.

NPK urinal: standalone or system operation
The NPK female urinal operates entirely without water. It can be installed on its own in existing toilets or integrated into the NPK urine collection system. The NPK male urinal offers an equivalent solution for male needs. Together, these devices ensure hygienic, discreet and inclusive collection. As a result, managers can easily adapt their installation to suit their technical constraints.
NPK system for urinals: three essential components
The NPK system is based on three complementary elements:
- a waterless urinal for women,
- a waterless urinal for men,
- a front-facing tank for storage.
Each component can be installed separately. This means that projects can evolve over time, whether they involve new builds or renovations.

NPK urinals: collection at source and recycling
NPK urinals collect urine directly at source in collective housing. The front reservoir then stores the urine securely. This system promotes its reuse as fertiliser in line with the circular economy. This principle is in line with ADEME guidelines on resource efficiency.
NPK urinals for public buildings and public access buildings
NPK urinals are designed for schools, sports facilities, public buildings and collective housing. They offer the following benefits:
- significant savings in drinking water,
- a reduction in maintenance costs,
- a reduction in environmental footprint,
- better effluent management.
