IWW HOLDING GEMEINNUTZIGE GMBH

Their core work

IWW is a German non-profit research centre specializing in water science, management, and infrastructure protection. Based in Mülheim an der Ruhr, they work on practical challenges including drinking water safety, contaminated land assessment, climate adaptation for water utilities, and smart water reuse systems. Their research bridges environmental science and engineering, with a strong applied focus on helping water utilities and municipalities manage resources under climate stress.

What they specialise in

How they've shifted over time

IWW's early H2020 work (2015–2018) centred on foundational environmental challenges: contaminated land assessment (Remediate) and climate adaptation for ongoing water management (BINGO). From 2019 onward, their focus shifted decisively toward smart, digitally-enabled water solutions — including smart data platforms, water reuse, circular economy models, and aquifer recharge. This trajectory shows a clear move from traditional water science toward technology-driven, climate-resilient water systems.

IWW is moving toward digitally-enabled, circular water management — expect future work combining IoT/data analytics with water reuse and aquifer recharge in climate-stressed regions.

How they like to work

IWW consistently operates as a contributing partner rather than a project leader, having coordinated none of their five H2020 projects. They work in large, multinational consortia — 114 unique partners across 16 countries suggests they integrate well into complex European teams. Their participation across diverse funding schemes (IA, RIA, MSCA-ITN) shows flexibility in adapting to different project structures and roles.

IWW has built a broad European network of 114 unique partners spanning 16 countries, indicating they are well-connected across the water research and innovation community. Their consortia tend to be large and geographically diverse, with no sign of clustering around a single national group.

What sets them apart

IWW occupies a distinctive niche as a non-profit SME research centre dedicated entirely to water — combining the agility of a small organization with deep domain expertise and a 114-partner European network. Unlike university labs, they maintain a strong applied orientation toward water utility operations and real-world infrastructure. Their combination of water security, smart technologies, and circular economy expertise makes them a versatile partner for any consortium addressing Europe's water challenges.

Highlights from their portfolio

• B-WaterSmart
  Their largest funded project (EUR 1.26M) and most thematically comprehensive — covering smart water technologies, governance, living labs, and circular economy in coastal Europe.
• STOP-IT
  Unusual cross-sector project combining water infrastructure with cybersecurity — demonstrates IWW's ability to work at the intersection of physical water systems and digital threats.
• MARSoluT
  An MSCA training network on managed aquifer recharge, showing IWW's commitment to next-generation researcher training and Mediterranean water scarcity solutions.
