Sustainable Water Soluitons

Water resources are under increasing pressure as cities grow and water consumption continues to rise. Every day, millions of liters of reusable grey water are lost through conventional wastewater systems, while valuable resources are consumed for applications that do not require fresh water.

Existing buildings were not designed for water recovery, and centralized solutions alone cannot meet the growing demand for sustainable water management. The future requires localized, intelligent and efficient solutions that recover water where it is used.

GRETA was developed with this vision: transforming grey water into a valuable resource through advanced treatment and smart electronic management. By combining automated control systems with efficient recycling technology, GRETA enables safe water reuse while reducing freshwater dependency.

Because sustainability is not only about saving water — it is about managing every drop intelligently.

Smart Water Recycling

GRETA automatically collects grey water from washbasins and other approved sources, then treats it through a multi-stage filtration process designed to support ANSI/NSF 350 compliance. Intelligent electronic controls continuously monitor water demand and automatically prioritize recycled water by supplying toilet systems with treated water before using mains water. The result is a fully automated Smart Water Recycling System that significantly reduces freshwater consumption while maximizing water efficiency.
