Article 10
Quality assurance of treatment, equipment and materials
1. Member States shall take all measures necessary to ensure
that substances or materials for new installations used in the
preparation, production, or distribution of water intended for
human consumption or impurities associated with such
substances or materials for new installations
a) do not remain in water intended for human consumption
in concentrations higher than is necessary for the purpose
of their use, and
b) do not, either directly or indirectly, reduce the protection
of human health provided for in this Directive and
c) do not lead to a water quality unacceptable to
consumers regarding organoleptic parameters.
Proposal continued
2. Measures required under paragraph 1 shall include the authorisation
of the use of substances and materials on basis of the framework for
assessing and controlling the health risks set out in Annex IV. Member
States shall notify their authorisation scheme in accordance with
Directive 98/34/EC
3. A Member State is deemed to comply with the requirement set out
under paragraph 2 where it refers in its national regulations to notified
authorisation schemes established by other Member States.
4. Community guidelines for the assessment required under paragraph 2
may be drawn up and revised in accordance with the procedure laid
down in Article 12.
5. The interpretive document and technical specifications pursuant to
Article 3 and Article 4 (1) of Council Directive 89/106/EEC of 21
December 1988 on the approximation of laws, regulations and
administrative provisions of the Member States relating to construction
products shall respect the requirements of this Directive. PM Reference
to other directives, e.g. Biocides Directive (disinfectants), Public
Procurement Directive, water heaters, water meters, …
Proposal continued
Article 11
Review of annexes
(-)
2. At least every five years, the Commission shall adapt
Annexes II, III and IV to scientific and technical progress.
Such changes as are necessary shall be adopted in
accordance with the procedure laid down in Article 12.
Proposal continued
Elements to be included in Annex IV
Framework for assessing and controlling
1. Introduction
1.1
Linking annex to Article 10, Article 4 (all
substances) and Annex I (specific
parameters)
1.2
Reference to new WSP provisions
1.3
Reference to relevant product directives,
inter alia CPD and Biocides Directive
Proposal continued
2.
General framework
2.1 Scope (from source to tap)
2.2 Assessment on basis of full formulation of substances and materials
2.3 Assessment criteria (organoleptic, general hygienic, migration of specific
substances, screening of unsuspected substances and enhancement of
microbial growth).
2.4 Setting of acceptance levels (common principles)
2.5 Listing of approved substances and materials (general). Reference to
common lists to be set up in accordance with Article 10.4 (new), including
reference to Commission Directive 2002/72/EC)
2.6 Approach to testing related to material types (matrix to be taken from EAS
proposal; organic, metallic, cementitious materials); details of regulatory
issues such as number of migrations, temperature of test waters and
conversion principles in community guidelines to be established in
accordance with Article 10.4 (new).
2.7 Treatment chemicals: Reference to existing EN-standards
2.8 Reference to CEN supporting test standards and harmonised product
standards

SECOND BARRIER:

Water Supply:
• Abstraction

• Storage
• Transport
• Distribution
according to
generally
acknowledged
technical
standards
Water Supply on the Basis
of Technical Standards
Water supply companies are
responsible for abstraction,
treatment, storage, transport and
distribution of drinking water.
Technical Standards shall be met
as well as the legal requirements
of the EU for drinking water
quality.
THIRD BARRIER: Safe Domestic Water Installation
Domestic
Installation:
• Prudent choice
of materials in
contact with
drinking water
• Safety devices
• Professional
Installation
Water suppliers responsibility
ends at the water meter.
Domestic installation shall
ensure that consumer receives
high quality drinking water at the
tap.
Domestic Installation
THIRD BARRIER: Safe Domestic Water Installation
Materials in contact
with drinking water
should not affect
water to its microbiological and
chemical properties.
Materials used:
steel (hot
galvanised,
stainless), copper,
plastic materials.
THIRD BARRIER: Safe Domestic Water Installation
Moreover safety devices
shall be mounted to
prevent backsiphonage
of water, i.e. by using
backflow preventers
Only qualified plumbers
- no Do-it-yourself men shall be entrusted for the
work in the domestic
installation!
Backflow preventer
The MULTI-BARRIER SYSTEM:
Basis for a Modern Drinking Water Supply in Europe
The interaction of all three barriers:
• consistent protection of the water
resources
• design, construction and operation of
water supply system in line with Technical
Standards (DIN, DVGW)
• professional expert planning, installation
and operation of domestic installations
according to the Technical Standards by
qualified plumbers guarantees that
consumer is supplied with highest
quality drinking water at the tap!
Main Regulations in Germany
• Federal water act (impl. 00/60/EC)
– water resources legislation in 16 federal states
(states water acts)
– Basic provisions relating to water resources
management measures
• Drinking Water Ordinance 2001 (impl. 98/83/EC)
– authorisation given in protection against infection act 2000
– responsibility for execution lies with the federal states (Länder)
• Ordinance on general conditions for the water supply
• Several ordinances in the 16 federal states
– e.g. self control of raw water
Execution
lies with
the
federal
states
No
influence
by
ministry !
Drinking water ordinance:
Contents
• Specific requirements for the quality of drinking water and of water for
food production and for drinking water treatment
• Provisions on drinking water quality, obligations of operators of water
supply facilities and supervision of operators by the health authorities
with respect to hygiene
• Limit values for substances harmful to health (e.g. heavy metals,
nitrates, organic compounds) and pathogens; defines the scope and
frequency of surveillance
• No specifications to implement these limits, e.g. what pipe materials
to use for compliance
• Only general requirements, refering to „generally acknowledged
technical standards“
Link between compliance with Technical
Standards and quality of drinking water in
the German Drinking Water Ordinance:
§4
(1) Water intended for human consumption must be
free from pathogens, wholesome and clean. This
requirement is deemed to be fulfilled if the generally
acknowledged technical standards are complied with
during abstraction, treatment and distribution and the
water intended for human consumption meets the
requirements laid down in sections 5 to 7.
German Drinking Water Ordinance:
§ 17
Special requirements
(1) For the construction or maintenance of installations for
the treatment or distribution of water intended for human
consumption only materials may be used that, when
coming into contact with water, do not shed any
substances in concentrations higher than unavoidable
according to the generally acknowledged technical
standards, or directly or indirectly lessen the protection of
human health provided for in this Ordinance, or alter the
smell or taste of the water; section 31 of the Act on Foods
and Commodities as published on 9 September 1997 (BGBl.
I p. 2296) shall not be affected. The requirement of sentence
1 shall be deemed to be fulfilled if the planning,
construction and operation of the installations comply at
least with the generally acknowledged technical standards.
German Drinking Water Ordinance:
§ 17
Special requirements
(2) Water supply installations from which water
intended for human consumption is supplied must not
be connected with water-bearing parts which carry
water or remove water that is not intended for human
consumption within the meaning of section 3 no. 1.
The entrepreneur and any other owner of a water
supply installation within the meaning of section 3 no.
2 must colour-code the pipes of different supply
systems in a durable way or have them colour-coded
during the assembly of these systems. They must
durably mark the taps of water that is not intended for
human consumption within the meaning of section 3
no. 1 or have them marked as these taps are mounted.
