Green Drain – Rethinking Infection Prevention at Drain Level

Green Drain develops innovative drain-seal technology designed to address an often-overlooked pathway in healthcare environments: the floor drain.

Hospital drainage systems can act as reservoirs for microorganisms and provide a pathway for air and aerosolised particles from wastewater systems into clinical environments. Green Drain provides a simple, passive engineering control designed to help reduce this environmental exposure pathway.

Our patented waterless one-way valve is installed directly into existing floor drains. It allows wastewater to flow down while restricting the upward movement of air and aerosols from the drainage system. The solution requires no power or water supply and can be installed in seconds, making it suitable for both existing healthcare facilities and new construction.

Green Drain is registered in EUDAMED as a Class I Medical Device under MDR (EU) 2017/745, and manufacturing is carried out under an ISO 13485:2016 certified quality management system.

Independent SGS testing of the GD demonstrated >99.9% retention of an aerosolised MS2 bacteriophage viral surrogate under controlled test conditions. Green Drain is designed as a supportive environmental engineering control and complements – rather than replaces – established hygiene and infection prevention procedures.

Our vision is simple: to make drain-level protection a standard part of infection prevention in healthcare facilities worldwide.

At MEDICA, we are looking to connect with hospitals, infection prevention specialists, healthcare engineers, architects and international distribution partners who share our ambition to create safer healthcare environments.
