RIEFILT team at industrial water treatment site

The manufacturer-independent infrastructure deal originator for industrial water treatment.

RIEFILT GmbH is a one-of-a-kind platform that connects industrial clients with optimal water treatment solutions. We don't manufacture, install, or operate — we originate deals. By remaining manufacturer-independent, we ensure every client gets the best technology at the best price, structured through BOOT, rental, or purchase models.

From 14 months planning to 90 days deployment

Our island faced a critical water shortage — 2,200 residents, peak tourist season approaching, and no budget for a desalination plant. RIEFILT structured a BOOT contract that eliminated our €1.8M capex barrier completely. The 800 m³/day RO system was operational within 90 days. We now pay per cubic meter, well below our previous water import costs.

42% lower total cost of water treatment

We needed to upgrade our WFI system to meet new EU Annex 1 requirements — without any production downtime. RIEFILT evaluated 5 manufacturers independently and recommended a solution we hadn't considered. The BOOT structure spread our €2.4M investment over 7 years. Result: full GMP compliance, zero production interruption, and 42% lower cost per m³ compared to our previous system.
