Infection control
at the drain level.
Where pathogens begin.

Floor drains in hospitals are not just a sanitary issue — the biofilm in the P-trap has been documented as a reservoir of resistant strains such as Pseudomonas aeruginosa, CRE, and Klebsiella pneumoniae. Studies published in the Journal of Hospital Infection show aerosolization of pathogens when water is flushed. Green Drain™ is a physical one-way seal with SGS-proven blocking of >99.9% of viral aerosols, registered in EUDAMED as a Class I medical device (EU 2017/745).

Problem & solution

The P-trap is the weakest point in healthcare infection control.

Hospital rooms, bathrooms, ICU units — every floor drain after patient discharge or extended room vacancy exposes the space to pathogen aerosolisation. Literature published in the Journal of Hospital Infection and the American Journal of Infection Control has documented drain-associated outbreaks across acute settings.

Without Green Drain™

  • The P-trap dries out within 5–10 days of non-use (isolation rooms between patients, decommissioned wards, refurbishment zones).
  • Each time water is released, the biofilm on the P-trap wall releases aerosolized pathogens into the room.
  • Pseudomonas aeruginosa, CRE, and Klebsiella pneumoniae colonize P-traps and are resistant to conventional disinfectants.
  • ICU units with their own sanitary facilities have been documented as a source of outbreaks in the professional literature.
  • Audits require a written procedure for controlling environmental sources and evidence of its implementation.

With Green Drain™

  • Physical one-way barrier — works even when the floor drain is completely dry.
  • SGS laboratory test (QDF25-0049810-01): >99.9% blockage of viral aerosols on MS2 bacteriophage surrogate
  • EU 2017/745 (MDR) — registered in EUDAMED as a Class I medical device
  • No chemicals, no plumbing work—installs in 30 seconds per drain.
  • Resistant to common hospital disinfectants (chlorine up to 5%, quaternary amines, isopropanol, ethanol)

Capacity of the HSE hospital network

The HSE-funded network includes HSE-run acute hospitals and Section 38 voluntary hospitals (the Mater, St James's, Beaumont, Tallaght, the UHL Group and others), serving thousands of inpatient beds nationwide. Every ward, every ICU, every isolation room and every staff washroom has floor drains that represent a potential vector for HCAI under HSE SARI guidelines.

Implementation

From audit to of the entire department in 14 days.

Our technical team works with the epidemiologist, the chief nurse, and the technical service—from mapping to delivery.

01

Audit

The technician maps all drains (rooms, bathrooms, sanitary nodes, kitchen blocks). We measure the internal diameter and the type of grate.

02

Recommendation

Written recommendation with sizes (GD 1.25 to GD 6), total number of pieces, and specification according to EN 1253-1.

03

Test

We place samples in five representative rooms for seven days. Your epidemiologist assesses the effect on the swabs.

04

Implementation

The technical service installs an entire department in a single day of work. No downtime, no plumber. No intervention for years.

Model Recommendation

Recommendation per type of space in the hospital

Irish HSE hospitals are typically built to EN 1253 standard. P-traps in patient rooms and sanitary units are predominantly 1.5″ (DN40) — the most common size. Operating theatres, sterilisation areas, and central kitchen drains use larger diameters. A typical acute hospital requires four to five different sizes throughout the building.

Questions

Most common doubts

Is Green Drain™ a medical device?

Yes. It is registered in the EUDAMED EU database as a Class I medical device under Regulation (EU) 2017/745 (MDR), intended to contribute to infection control in healthcare facilities.

Is Green Drain™ resistant to hospital disinfectants?

Yes. The silicone material is resistant to sodium hypochlorite up to 5%, quaternary ammonium compounds, isopropanol, and ethanol at standard hospital concentrations. A detailed chemical compatibility list is provided upon request.

How do you clean it?

Use a standard drain disinfectant. The seal is not disassembled or removed for cleaning—it's treated the same as a standard U-bend. Perform a visual inspection once a month.

How long does it last?

The expected lifespan is 5 years under normal use. ASSE 1072-2020 is tested for over 2,500 opening and closing cycles.

Complete solution

Three products.
One protection portfolio.

Green Drain™ doesn't work alone — for maximum drain control it's combined with GD Uri-Tabs™ (urinals) and GreenSwirl™ (biofilm bio-cleaning).
