A property manager overseeing a portfolio of buildings can't send a crew every weekend because of odours in the drains. They need a systematic solution that reduces the number of calls in the dispatch system and keeps tenants happy. Green Drain™ is a one-time purchase that lasts for five years.
A smell complaint is a classic ticket in the FM system. The technician arrives, flushes the P-trap, returns in 14 days—same issue. Labor costs rise, and the tenant doubts the building's quality.
The FM industry in Croatia is rapidly developing. Corporate clients are demanding ESG and sustainability metrics. Smell complaints are one of the most common ticket types — the solution is quickly evolving toward passive systems that don't require repeated interventions.

The property manager takes the specification, the dispatch system doesn't open new smell tickets at the facility — the recommendation is being rolled out across the portfolio.
A building with a history of smell tickets — pilot, 90-day evaluation.
Number of open tickets — pre/post analysis for the sustainability report.
Central procurement takes over the specification for the rest of the portfolio.
Prioritized building implementation — typically 6–18 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%). Standardization 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™ (cleaning).
Patented silicone seal — one SKU covers 95% of drains in the portfolio. Equipment standardization across tens or hundreds of buildings.
Bio-enzyme urinal tablets — a unique service interval across the entire FM portfolio, with reduced maintenance variability.
Biofilm bio-cleaning — systematic treatment of drains across the entire portfolio. Fewer odour alarms, lower OPEX per facility.
We come to the site, map the drains, and provide a written recommendation—no cost, no obligation.
