The airport operates 24 hours a day. Closing for P-trap maintenance is impossible. Seasonal peaks (Dublin, Cork and Shannon — summer / Christmas / sporting fixtures, plus the daa T2 night-time freight operation) put operators under extreme strain. Green Drain™ solves unpleasant odours and hazardous sewer gases — no reintervention for years.
The terminal operates 18–24 hours a day. The hangar and technical support are available around the clock. The passenger restrooms in the terminal are heavily used during the day but not at night, when the drains can dry out.
Dublin Airport handled ~33M passengers in 2024, operated by daa. Cork (ORK) and Shannon (SNN) serve as secondary international gateways. Terminal restrooms, airline lounges and F&B outlets are the critical hygiene zones — high passenger throughput plus constant operating hours make passive sealing essential.

Large airports have a 4–6-hour nighttime low-traffic window. Our technicians work in zones escorted by security.
The technician is mapping the terminal, the hangar, and the customs area — accompanied.
One sanitary or customs zone — 30-day evaluation.

By zones during the night slots — one zone = one night.
Irish airports (Dublin, Cork, Shannon, Kerry, Knock, Donegal) have structurally distinct zones. Passenger restrooms are predominantly DN50. Airline lounges use BC sizing. Hangars, MRO workshops, and cargo zones are industrial in scale.
Green Drain™ doesn't work alone — for maximum drain control it's combined with GD Uri-Tabs™ (urinals) and GreenSwirl™ (biofilm bio-cleaning).
Patented silicone seal for all terminal floor drains. The seal protects during low-flow periods at night and shields passengers from H₂S.
Bio-enzyme tablets for all urinals in the terminal — high daily throughput from a 24/7 operation. Fewer service interventions during peak hours.
Bio-cleaning of biofilm in the terminal and ground-floor restroom facilities. Reduces seasonal odors in waiting rooms and the food court.
We come to the site, map the drains, and provide a written recommendation—no cost, no obligation.
