ACCIONA AGUA SA

Their core work

ACCIONA AGUA SA is the water management division of ACCIONA, one of Spain's largest infrastructure and services groups, specialising in the design, construction, and operation of water treatment and desalination facilities at industrial scale. In EU research projects, they contribute operational infrastructure — real treatment plants and industrial testbeds — that allow innovative technologies to be demonstrated under genuine working conditions rather than laboratory settings. Their technical expertise spans the full water cycle: from collecting and treating urban and industrial wastewater, through advanced desalination processes, to recovering valuable by-products such as phosphorus, bio-polymers, and critical raw materials from water streams. This makes them an unusually strong bridge between laboratory-scale research and commercial water technology deployment.

What they specialise in

How they've shifted over time

In their earliest H2020 project (INTEGROIL, 2016–2019), ACCIONA AGUA focused on decision-support tools and integrated management systems to optimise industrial water reuse — an IT-meets-operations challenge where the goal was smarter use of existing water infrastructure. By the time WATER-MINING began (2020–2024), the agenda had shifted substantially toward the circular economy: recovering phosphorus, bio-polymers, critical raw materials, and energy from wastewater and desalination brines, with service-based business models as an explicit objective. The trajectory is clear — from treating water more efficiently to extracting economic value from the waste streams that treatment generates.

ACCIONA AGUA is moving toward positioning water treatment not as a cost to minimise but as a source of recoverable materials and energy, aligning with EU critical raw materials policy and the circular economy agenda — making them a relevant partner for any consortium combining water, materials, or bio-economy themes.

How they like to work

ACCIONA AGUA has taken on both coordinator and partner roles across their two projects, showing they are comfortable leading as well as contributing within larger consortia. Their involvement in WATER-MINING — a large, multi-country initiative — alongside 52 unique partners across 15 countries suggests they participate in ambitious, well-networked projects rather than small bilateral collaborations. As an industrial operator, their typical contribution is access to real infrastructure for demonstration, operational data, and routes to commercial scale-up.

With 52 unique consortium partners across 15 countries, ACCIONA AGUA operates in broad European networks — a reach that likely reflects their role in WATER-MINING, one of the larger H2020 water consortia. Their geographic spread suggests strong connections across southern, central, and northern Europe, consistent with their parent group's pan-European infrastructure footprint.

What sets them apart

Most water-sector research partners are universities or technology SMEs; ACCIONA AGUA is an industrial operator that runs actual desalination and wastewater treatment plants at scale, giving consortia something rare: a real demonstration environment with genuine operational constraints, regulatory context, and a commercial pathway. Their parent group's global project portfolio means they also understand procurement, contracting, and scale-up in a way that academic partners typically do not. For a consortium needing credible industrial validation and a plausible route to market, ACCIONA AGUA adds legitimacy that is difficult to substitute.

Highlights from their portfolio

• INTEGROIL
  Their largest H2020 project (EUR 883,704) and the only one where they served as coordinator, demonstrating a decision-support system for integrated industrial water reuse — a rare combination of IT and water operations leadership.
• WATER-MINING
  A flagship H2020 circular economy water project targeting recovery of phosphorus, critical raw materials, bio-polymers, and energy from desalination brines and urban wastewater, placing ACCIONA AGUA at the convergence of water treatment and materials recovery.
