Summary As proposed, CADA does not set technical limits for wastewater discharge from data centres. Instead, it builds an administrative framework to accelerate deployment by requiring Member States to designate single information points that help operators obtain the necessary authorisations — including those for wastewater discharge — in data centre acceleration zones. Substantive discharge standards continue to come from existing EU environmental law, not from CADA.

Detail

CADA, proposed by the European Commission on 3 June 2026, aims to address the EU's shortage of computing capacity and reliance on third-country cloud providers. A central pillar is accelerated data centre deployment, achieved by streamlining permitting and administration, since environmental and infrastructure approvals are often significant bottlenecks.

CADA does not replace or amend existing EU environmental legislation — such as the Industrial Emissions Directive or the Water Framework Directive — that governs the quality and quantity of wastewater discharges. Instead, it focuses on the process of obtaining the necessary authorisations. It requires Member States to designate data centre acceleration zones where deployment is facilitated, and provides that the permit-granting procedure for projects in such zones shall not exceed 12 months from the moment a comprehensive application has been submitted (Article 13(5)).

To support this, CADA provides for single information points. Under Article 12(1), Member States shall designate one or more single information points for operators of projects in acceleration zones, and the operator has a right, upon request, to be assisted across the project's entire lifecycle with respect to all authorisations required for deployment.

Specifically, Article 12(2)(c) lists the single information point's role in coordinating, facilitating, monitoring, and sharing information on procedures relating to "authorisations regarding water abstraction, wastewater discharge, and heat utilisation and recovery." This means operators need not navigate fragmented authorities alone; the point coordinates with the relevant environmental authorities responsible for wastewater discharge permits.

CADA also provides for an aggregated baseline permit for each designated acceleration zone (Article 13(2)). This permit, issued by public authorities, covers the permits and administrative authorisations required for data centre projects in the zone, excluding installation-specific permits. Before issuing it, Member States must carry out all necessary procedures and assessments, including relevant environmental assessments at zone level (Article 13(3)). The text does not state that wastewater discharge permits are always covered, but the mechanism is designed to pre-clear common regulatory hurdles for projects in the zone.

CADA also addresses sustainability: under Article 11, when setting sustainability requirements for data centres in acceleration zones, Member States shall use the key performance indicators specified in Delegated Regulation (EU) 2024/1364. While these focus on energy and resource efficiency, they reinforce that data centres must meet high environmental standards.

What this means for you

For public-sector and procurement officers managing local data centre projects, the role of single information points is central.

  1. Designating single information points. Your authority may need to designate, or integrate into, a single information point for projects in acceleration zones, with capacity to coordinate with the environmental agencies responsible for wastewater discharge authorisations. Weak coordination could delay projects.
  2. Streamlined permitting. Anticipate that wastewater discharge authorisations form part of a coordinated process subject to the 12-month limit in Article 13(5). Ensure environmental assessment teams are resourced accordingly.
  3. Baseline permits. Investigate whether your zone's aggregated baseline permit can streamline common wastewater discharge scenarios, reducing burden for the authority and investors alike.
  4. Sustainability compliance. Although CADA sets no new wastewater limits, it reinforces sustainable operation. Ensure projects seeking acceleration-zone benefits comply with existing EU and national water law; the single information point should confirm early engagement with environmental authorities.

Common misconceptions

  • Misconception: CADA sets new EU-wide wastewater discharge limits.
    • Reality: No. CADA introduces no new technical standards for wastewater quality or quantity. It defers to existing EU environmental law (such as the Industrial Emissions Directive and Water Framework Directive) and only streamlines the administrative process.
  • Misconception: Single information points issue wastewater permits.
    • Reality: No. Their role under Article 12(2)(c) is to coordinate, facilitate, monitor, and share information. The actual decision remains with the competent environmental authority.
  • Misconception: All data centres automatically get accelerated wastewater permitting.
    • Reality: Only projects deployed in designated acceleration zones benefit from the streamlined processes and single information point support. Projects outside these zones follow standard national procedures.
