Drinking Water Directive

Introduction

Directive (EU) 2020/2184, commonly known as the Drinking Water Directive (Recast), is the primary piece of EU legislation regulating the quality of water intended for human consumption. It replaces Council Directive 98/83/EC to align with the latest scientific advice (such as the WHO guidelines), technical progress, and the European Green Deal. The Directive aims to protect human health from the adverse effects of contaminated water by ensuring that it is wholesome and clean, while also improving access to water for all EU citizens.

Main Goal

The legislation pursues two primary objectives:

1. Health Protection: Ensuring safe drinking water by setting updated quality standards for microbiological and chemical parameters.
2. Access to Water: Improving access to tap water, particularly for vulnerable and marginalised groups, and promoting its consumption to reduce plastic waste from bottled water.

Who It Applies To

The Directive applies to:

• Member States: Responsible for transposition, monitoring, and enforcement.
• Water Suppliers: Entities supplying water for human consumption (public or private utilities).
• Food Businesses: Operators using water in the manufacture, processing, or preservation of food (unless satisfied that water quality does not affect food safety).
• Manufacturers: Companies producing materials (pipes, taps, valves) and treatment chemicals/filter media that come into contact with drinking water.
• Property Owners/Managers: Specifically for "priority premises" (e.g., hospitals, schools, hotels) regarding domestic distribution systems.

Key Dates

• Entry into Force: January 12, 2021.
• Transposition Deadline: Member States must transpose provisions into national law by January 12, 2023.
• New Parameter Compliance: Compliance with new parameters (e.g., Bisphenol A, Chlorate, PFAS) is required by January 12, 2026.
• Material Standards: Methodologies for testing materials in contact with water to be established by January 12, 2024, with positive lists by January 12, 2025.

Exemptions

The Directive does not apply to:

• Natural mineral waters (covered by Directive 2009/54/EC).
• Medicinal product waters (covered by Directive 2001/83/EC).
• Small supplies (<10 m³/day or <50 persons) unless supplied as part of a commercial or public activity.

Key Provisions

1. Updated Quality Standards: Introduces stricter limits for existing pollutants (e.g., lead) and adds new ones (e.g., PFAS, endocrine disruptors like Bisphenol A, microplastics watch list).
2. Risk-Based Approach: A comprehensive safety approach covering the entire supply chain:
   • Catchment Areas: Assessment of risks at the source.
   • Supply System: Operational monitoring by suppliers.
   • Domestic Distribution: Risk assessment of piping inside buildings (focus on Legionella and Lead).
3. Materials in Contact with Water: Harmonised EU-wide hygiene requirements for materials used in water infrastructure to prevent contamination.
4. Access to Water: Obligations to identify people without access and take measures to improve access (e.g., public fountains).
5. Information to the Public: Water suppliers must provide transparent, up-to-date information to consumers on invoices or apps regarding quality, price, and consumption volume.

Penalties

Member States are required to lay down rules on penalties applicable to infringements of national provisions adopted pursuant to this Directive. These penalties must be effective, proportionate, and dissuasive. Failure to comply with quality standards requires immediate investigation and remedial action; if a potential danger to health exists, supply must be prohibited or restricted.
