The proposed regulation COM(2026) 100 final, published by the European Commission on March 4, 2026, does not regulate water. Yet its mechanisms for industrial acceleration, permitting simplification, public procurement, and foreign investment screening have direct consequences for how water cycle companies operate, bid for contracts, and invest.
The Industrial Accelerator Act (IAA) starts from a diagnosis the water sector knows well: European industry is losing competitive ground, facing high energy costs, and decarbonizing far too slowly. Manufacturing's share of GDP has fallen from 17.4% to 14.3% between 2000 and 2024, and more than half of the decarbonization projects announced since 2023 remain unexecuted.
To reverse this trend, the regulation is built around four pillars: faster permitting, the creation of lead markets for low-carbon, European-made products, screening conditions on foreign direct investment in strategic sectors, and the designation of priority industrial zones. Water does not appear as a target sector — but each of these pillars has direct implications for the water cycle. Cross-cutting elements of the text, such as energy costs, strategic dependencies, and cybersecurity requirements, reinforce that connection further.
The proposed Industrial Accelerator Act has direct consequences for how water cycle companies operate, bid for contracts, and invest
Permitting acceleration: what changes for industrial water projects
Article 5 of the IAA requires member states to establish a single authorization procedure for all industrial manufacturing projects, coordinated by a competent authority that must issue a comprehensive decision within legally defined timeframes. Article 4 requires this process to be fully digital, delivered through the future European Business Wallets.
The proposal extends the accelerated regime of the Net-Zero Industry Act (NZIA) to all decarbonization projects in energy-intensive industries
For utilities and operators working with industry, the practical consequences are immediate. Any industrial project requiring water abstraction, discharge to a watercourse or sewage network, or connection to wastewater treatment systems — which covers virtually all water-intensive industry — will fall under this new coordinated framework. Authorization for use of public waters will continue to be governed by the relevant sectoral legislation, but the administrative coordination obligations imposed by the IAA could significantly reduce total processing times, which in complex industrial projects can exceed two years according to sector estimates.
Article 6 goes further, explicitly extending the accelerated regime of the Net-Zero Industry Act (NZIA)— including single points of contact and maximum timeframes — to all decarbonization projects in energy-intensive industries, regardless of whether they produce net-zero technology components. This broadens the range of projects that, as they decarbonize, will require process water solutions, cooling, effluent treatment, or ultrapure water production for hydrogen. Demand for these services will no longer depend on individual business decisions, but on a regulatory timetable with legally binding deadlines.
Lead markets for low-carbon products: the new procurement standard for water utilities
Chapter III introduces mandatory low-carbon content and Made-in-EU requirements for public procurement and public support schemes across strategic sectors: steel, cement, aluminum, vehicles, and net-zero technologies.
For water utilities, the impact operates on two levels. The first is direct: companies bidding for public works or supply contracts in the covered sectors — construction, transport, energy generation — will need to demonstrate that the materials used meet the carbon intensity thresholds set by the Commission through delegated acts. This affects pipes, metal structures, concrete, and electromechanical equipment in treatment plants and distribution networks.

The second level is indirect but equally significant: Article 12 requires that at least 45% of national budget allocated to support schemes covered by the regulation be designed in accordance with these requirements. As carbon and origin criteria become entrenched as the standard in general public procurement — a trend the IAA reinforces and that the forthcoming revision of the public procurement framework will need to integrate — emissions traceability will cease to be a competitive differentiator and become a basic condition for market access. This shift is already visible in how leading utilities manage their capital programmes: United Utilities has embedded a carbon management platform across its entire £13 billion AMP8 investment cycle to measure and reduce the carbon impact of construction and whole-life operations, while Scottish Water applies a formal carbon reduction hierarchy and set of golden rules to every infrastructure project, embedding low-carbon materials and renewable energy from the design stage.
Conditions on foreign direct investment: a lever the water sector should seize
Chapter IV establishes that foreign direct investments exceeding €100 million in strategic emerging sectors — batteries, electric vehicles, photovoltaics, and critical raw materials — are subject to mandatory conditions if the investing country holds more than 40% of global manufacturing capacity in that sector. Those conditions include capping foreign ownership at 49%, technology transfer requirements, the hiring of European workers, and integration into local value chains.
Water does not appear on this list. But Article 29 tasks the Commission with assessing, in its triennial review, whether it is appropriate to extend these requirements to additional sectors critical to economic security. Several technologies central to the water cycle — reverse osmosis membranes, SCADA systems for distribution networks, water quality sensors — have a concentration of manufacturing outside Europe that, in terms of strategic dependency, is comparable to that of solar panels or batteries at the time those were regulated.
Industrial acceleration areas: new territorial pressures on water resources
Chapter V introduces industrial manufacturing acceleration areas — geographically defined zones that member states must designate within twelve months of the regulation entering into force. These areas will benefit from a base permit covering common authorizations, along with favourable conditions for financing, training, and access to critical raw materials.
Europe's leading desalination operators, are already pushing the boundaries of renewables integration, AI-driven automation, and energy recovery
Article 26 requires states to carry out periodic analyses of each area's energy needs, with horizons set at 2030, 2040, and 2050, to feed into grid planning. The same logic applies directly to water: the concentration of industrial activity in defined zones generates predictable, concentrated water demands that are not accounted for in current river basin management plans.
The regulation also prioritizes artificial land, industrial land, and brownfield sites for these areas (Article 25.3). Many of these locations have contaminated soils and impacts on underlying aquifers. Designating industrial acceleration areas on such land makes hydrological remediation a prerequisite — not an option — before operations can begin.
Cross-cutting themes: energy and cybersecurity
The regulation explicitly acknowledges that high energy costs are one of the main obstacles facing European industry. Its response is to accelerate the deployment of net-zero technologies — solar, wind, battery storage, electrolyzers — through European-origin requirements in auctions, public procurement, and support schemes (new Annex II of the amended NZIA).
For the water sector, this acceleration has one familiar dimension and one less obvious. The familiar side is operating cost: pumping, treatment, and especially desalination are energy-intensive, and cheaper renewable energy directly improves the economic viability of solutions such as advanced water reuse and large-scale desalination. ACCIONA and Sacyr Water, among Europe's leading desalination operators, are already pushing the boundaries of renewables integration, AI-driven automation, and energy recovery in large-scale plants, while acknowledging that fully decarbonizing baseload desalination remains the sector's next major frontier.
The industrial acceleration the IAA pursues will generate, in the territories where it concentrates, additional water demand
The less obvious side is the water demand generated by net-zero technologies themselves. Green hydrogen electrolyzers require large volumes of ultrapure water, and battery plants and solar panel manufacturing processes have significant process water needs. The industrial acceleration the IAA pursues will generate, in the territories where it concentrates, additional water demand that current basin plans do not account for. The strategic importance of this link is already driving consolidation in the water technology sector:
Nijhuis Saur Industries recently acquired a Dutch specialist with over 100 ultrapure water pilot installations for the hydrogen sector worldwide, a direct response to the growing need to supply green hydrogen production with reliable, high-purity water. At the utility level, Severn Trent became the first UK water company to achieve Carbon Trust Route to Net Zero certification, committing to 100% renewable energy and net-zero operational carbon by 2030, while Ruhrverband in Germany reached full energy neutrality in 2023 and is now using AI and sensors to address residual process emissions — the kind of end-to-end approach that binding decarbonization timelines will increasingly demand. Veolia's AI platform for real-time monitoring of water-related energy use and GHG emissions at industrial sites is precisely the tool that clients operating under those deadlines will expect from their water partners.
Alongside this, the IAA extends cybersecurity requirements to the control systems, SCADA, and remote access infrastructure of energy technologies. The new Articles 26, 28b and 28c, amending the NZIA, exclude vendors identified as high-risk from any public contract, renewables auction, or support scheme involving these systems — whether in the context of auctions (Article 26), public support schemes (Article 28b), or Member State support to net-zero technology manufacturing (Article 28c). For the water sector, this is a clear regulatory signal: distribution networks, treatment plants, and remote monitoring systems are equally exposed, and the trajectory of European legislation — the NIS2 Directive, the forthcoming revision of the Cybersecurity Regulation — points toward equivalent requirements for critical water infrastructure.
Conclusion: the IAA redefines the competitive landscape for the water sector
The Industrial Accelerator Act is not water legislation. But it sets boundary conditions that affect how water infrastructure is planned, procured, financed, and operated
The Industrial Accelerator Act is not water legislation. But it sets boundary conditions that affect how water infrastructure is planned, procured, financed, and operated in a context of accelerated reindustrialization.
Its implications for utilities and operators are concrete: new carbon standards throughout the supply chain, increased water pressure in industrial territories, opportunities in industrial decarbonization projects, and a policy window to position water technologies as strategic European assets.
In a scenario where Europe wants to reindustrialize and decarbonize simultaneously, there is no industry without water. The sector has both the need and the opportunity to play an active role in shaping this new framework.
