A property manager overseeing a portfolio of buildings cannot keep sending a crew out because of odours from the drains. They need a systematic solution that reduces the number of work orders and keeps tenants happy. Green Drain™ is a one-off purchase that lasts about five years.
An odour complaint is a classic work order in facility management. The technician arrives, flushes the trap, and is back two to four weeks later with the same issue. Labour costs climb and the tenant starts to question the building's quality.
The FM industry in Croatia is rapidly developing. Corporate clients are demanding ESG and sustainability metrics. Odour complaints are one of the most common work-order types — the solution is quickly evolving toward passive systems that don't require repeated interventions.

The property manager takes the specification, no new odour work orders are raised for the facility — the recommendation is being rolled out across the portfolio.
A building with a history of odour complaints — pilot install and a 90-day evaluation.
Open tickets counted before and after, for the sustainability report.
Central procurement takes over the specification for the rest of the portfolio.
Buildings done in priority order — typically 6 to 18 months.
A typical FM portfolio in Croatia is a mix of office buildings (40–60 %), hotels (20–30 %), retail centres (10–20 %), and industrial facilities (5–10 %). Standardisation across the portfolio — GD 2 and GD 3 together cover ~80 % of needs. Central procurement handles all sizes in a single tender.
Green Drain™ doesn't work alone — for maximum drain control it's combined with GD Uri-Tabs™ (urinals) and GreenSwirl™ (drain unblocking).
Patented silicone seal — two sizes (GD 2 and GD 3) cover roughly 80 % of drains in a typical portfolio. Standardised equipment across tens or hundreds of buildings.
Bio-enzymatic urinal tablets — one service interval across the whole FM portfolio, so maintenance stops varying from site to site.
Biological cleaning of biofilm — drains treated systematically across the portfolio. Fewer odour tickets and lower OPEX per building.
We come to the site, map the drains, and provide a written recommendation — no cost, no obligation.
