Description
The NPK female urinal is a waterless urinal designed for collecting urine at the source in restrooms in multi-family housing and public buildings. It can be installed in existing restrooms without a water mains connection, in both new construction and renovation projects.

The NPK system: three complementary components
The NPK female urinal can operate independently or be integrated into the complete NPK urine collection system. This system consists of three elements, each of which can be installed independently depending on the technical and budgetary constraints of the project:
- NPK female waterless urinal
- NPK male waterless urinal
- Front-mounted tank for urine storage
The collected urine is stored securely in the front tank, then can be used as a liquid agricultural fertilizer rich in nitrogen (N), phosphorus (P) and potassium (K) — hence the name NPK — in a circular economy approach in line with the guidelines of ADEME.

Uses and benefits
The NPK system is designed for schools, sports facilities, public buildings, and multi-family housing. It allows for:
- a significant saving of drinking water — zero liters per use
- a reduction in sanitary maintenance costs
- a reduction in the building’s environmental footprint
- controlled management of effluents and their agricultural use
