Ministries, courts, government institutions, and barracks—buildings with thousands of drains and strict public procurement procedures. The specification must include the standard, certificate, service life, and SDS. Green Drain™ covers all elements required for tender submission.
The ministerial complex has hundreds of P-traps. The barracks are more like an enclosed compound. The technical service is overloaded; odours are appearing, and procurement takes six months.
All procurement is conducted through the Electronic Public Procurement Bulletin Board (EOJN). The Public Procurement Act stipulates that every item must have a defined specification and evidence requirements. The specification must be non-discriminatory—which facilitates the entry of solutions that comply with international standards.

We are sending the specification and technical documentation for inclusion in the tender. Later, we will submit our bid through EOJN.
PDF specification for tender submission — standard, certificate, lifespan, SDS.
Pre-tender pilot on a smaller facility — proof of concept.
Open process — we submit all documentation.

The Croatian public administration includes ministries, courts, barracks, state institutions, and local self-government. Each type of facility has a different profile — ministries are typically BC profile, barracks have dormitories + kitchen blocks + garages, and courts are offices with constant traffic. The specification is submitted through the Electronic Public Procurement Bulletin (EOJN).
Green Drain™ doesn't work alone — for maximum drain control it's combined with GD Uri-Tabs™ (urinals) and GreenSwirl™ (cleaning).
Patented silicone seal for floor drains in ministries, courts, and barracks. ASME 1072-2020 spec for EOJN public procurement, EU MDR documentation.
Bio-enzyme urinal tablets for public restrooms. EU 528/2012 BPR compliant, documentation for procurement tenders.
Biofilm bio-cleaning in public sanitation systems. No hazardous SDS chemicals — simplified technical documentation for tenders.
We come to the site, map the drains, and provide a written recommendation—no cost, no obligation.
