BACKGROUND
GENERAL DEFINITIONS
The relevant regulations (for private drinking water suppliers)
The following regulations apply to the approval of substances and products used in the provision of
private water supplies within the United Kingdom:
a) England - Regulation 5 of The Private Water Supplies Regulations 2009 (Statutory Instruments 2009
No 3101) http://dwi.defra.gov.uk/stakeholders/legislation/pwsregs2009.pdf
b) Wales – Regulation 4A of The Private Water Supplies (Wales) (Amendment) (No. 2) Regulations
2010 (Welsh Statutory Instrument 2010 No. 1384 (W.123) –
http://www.legislation.gov.uk/wsi/2010/1384/made
c) Northern Ireland – Regulation 6 of The Private Water Supplies (Amendment) Regulations (Northern
Ireland) 2010 (Statutory Rules of Northern Ireland 2010 No.131) http://www.legislation.gov.uk/nisr/2010/131/contents/made .
This list applies to water supplied under Regulation 5 of the Private Water Supplies Regulations 2009
and Regulation 4A The Private Water Supplies (Wales) Regulations 2010.
Where reference is required to specific regulatory requirements, these are given in footnotes.
The List
The list published here is not exhaustive with respect to Regulation 31 approved products or WRAS
approved products. Both of these lists are continually being updated, and the most up to date lists should
be consulted in order to provide assurance that products are approved. This list contains examples of
products that are likely to be found or used in private water supplies. Current lists for Regulation 31 and
WRAS approved products may be found at http://dwi.defra.gov.uk/drinking-water-products/approvedproducts/soslistcurrent.pdf and http://www.wras.co.uk/Directory/ respectively.
INTRODUCTION
The products in this list have only been assessed for safety for use in water supplies; they
have not been assessed for fitness for purpose.
Section 69 of the Water Industry Act 1991, as amended by the Water Act 2003, gave the
Secretary of State for the Environment, Food and Rural Affairs and the Welsh Ministers
powers to make regulations controlling substances, processes and/or products that are used in
the treatment and provision of private water supplies. Section 76B of the Water (Scotland)
Act 1980 gives Scottish Ministers similar powers.
The Drinking Water Inspectorate (DWI) carries out the approval process for the Authorities
for the whole of the United Kingdom, under the relevant Regulations. DWI accepts
applications for approval of products used both before the treatment works, and in water
distribution systems up to the point of delivery to premises.
The relevant regulations concern the introduction of substances and products (including
construction products) and processes for use in the treatment and provision of drinking water
supplies. They implement the requirements of Article 10 of the European Union Directive
2
98/83/EC on the quality of water intended for human consumption, in respect to substances
and materials used in the preparation and distribution of water up to the point of delivery to
premises. They do not transpose the requirements of the Directive with regard to the premises
(water supply systems within buildings). In England and Wales these requirements are dealt
with by the water industry Water Regulations Advisory Scheme (WRAS) under the Water
Supply (Water Fittings) Regulations 1999. In Scotland these are dealt with by Scottish
Water’s Water Byelaws 2004, and in Northern Ireland by The Water Supply (Water Fittings)
Regulations (Northern Ireland) 2009
Under the relevant regulations drinking water suppliers shall not apply or introduce any
substance or product into public drinking water supplies unless the requirements of the
relevant regulations are met.
APPROVAL UNDER REGULATION 5
Products may be suitable approved under Regulation 5 of the PWS in one of five ways:
1. Listed in the Secretary of State’s list of approved products for use in Public Water
Supply in the United Kingdom (current version is available on the DWI website);
2. Listed in the Water Regulations Advisory Service (WRAS) Water Fittings and
Materials Directory (available on the WRAS website: www.wras.co.uk) as a suitable
material for use in plumbing systems within buildings;
3. The particular usage of the product/substance results in either a minimal surface area
exposure or a transient contact time with water and testing using BS6920
methodology has shown that the product/substance does not give rise to an
objectionable taste or odour and does not encourage microbial growth.
4. Treatment chemicals conforming to a BS:EN standard and dosed in accordance with
any national conditions of use (Current BS:EN standards and conditions of use are
shown in the Secretary of States List of approved products for use in Public Water
Supply in the United Kingdom).
5. Included in the Transitional List of traditional products and substances for use in
Private Water Supplies
3
INTRODUCTION TO THE LIST OF APPROVED PRODUCTS
All approved products must be used in accordance with any specific conditions of
approval, listed against the product names. In addition, use is in accordance with
an Instructions for Use document provided by the product manufacturer.
THE APPROVAL OF A PRODUCT
Approval is based upon consideration as to whether the use of a substance or product will
adversely affect the quality of the water supplied, or cause a risk to the health of consumers; no
consideration is given to fitness for purpose and approval by the Authorities must not be taken as a
favourable assessment of the performance or merits of any substance or product. It is the
responsibility of the relevant person to ensure fitness for purpose.
Warning: The inclusion of products/substances in any of the above
categories or on any List published by DWI does not signify an
endorsement of its fitness for purpose or any other merits.
4
CRITERIA FOR INCLUSION ON TRANSITIONAL LIST FOR USE IN
PRIVATE WATER SUPPLIES
Regulation 5(1) of the Private Water Supplies Regulations 2009 requires that any
product or substance used in a private supply after the coming into force of these
Regulations must be a product or substance that would be permitted to be used
in a water supply under Regulation 31 of the Water Supply (Water Quality)
Regulations 2000. Although a wide variety of products and substances have been
used for many years in private water supplies, as yet very few have been
evaluated formally for placing on the Secretary of State’s List of Approved
Products/Substances. For this reason, DWI has put in place transitional
arrangements for compliance and these are set out below.
Any product or substance which has been used in no fewer than three different
private supplies for at least 12 months prior to application for inclusion on the list
may be deemed to comply with Regulation 5 provided there is evidence to show
that the supplies in question were of satisfactory water quality and there is no
history of consumer complaints or adverse health effects.
It is expected that manufacturers/suppliers of any product or substance which are
deemed compliant under these transitional arrangements will obtain guidance
from DWI on the steps required in order to obtain approval under Regulation 31.
DWI will add products/substances to a “transitional” list of products/substances
on receipt of the following information:
(i) locations of 3 or more private water supplies where the product or substance
has been in use for at least 12 months; and
(ii) testing and other relevant data to demonstrate satisfactory water quality and
the absence of public health or consumer concerns and
(iii) product information including conditions of use.
A form for applicants is available at http://dwi.defra.gov.uk/private-water-
supply/installers/Reg5application.doc

LOW CONTACT COMPONENTS AND PRODUCTS (Regulation 31(4)(b))
INTRODUCTION
Products that offer low (trivial) surface area and/or short (transient) contact time with water
intended for drinking purposes thus may be permitted to be used under regulation 31(4)(b) of
the Water Supply (Water Quality) Regulations, and hence under Regulation 5 of the Private
Water Supplies.
Regulation 31(4)(b) of the Water Supply (Water Quality) Regulations covers products used in
contact with water intended for human consumption where the contact surface area and/or
contact time are low. These products do not require the same rigorous evaluation as that
applied to products such as pipes and their coatings. Full details of the types of products
covered under this requirement are given in Section 3 of Advice Sheet 8
(http://www.dwi.gov.uk/drinking-water-products/advice-and-approval/Advicesheet8.pdf).
This Advice Sheet also contains guidance on the use of these components and products in the
provision of public water supplies.
To summarise this sheet, The Secretary of State is satisfied that substances or products either
alone or in combination with any other substance or product in the water is unlikely to affect
adversely the quality of the water supplied when
(i) that product or substance offers low (trivial) surface area contact or short (transient)
contact with the water; and
(ii) that product or substance does not give rise to unintended odour/flavour to the water and
does not support the growth of microbial organisms.
It is the responsibility of the Local Authority to check whether products fall into this category
by reference to the exemplar list in section 2 of Advice Sheet 8 or by calculating whether the
particular product can be shown to only expose a small surface area to the water . Example
calculations can be found in Advice Sheet 8. A non-exhaustive list of examples of products
that are likely to fall into this category are described below.
It is the responsibility of the Local Authority to satisfy themselves that they have
sufficient evidence to make an assessment of whether products fall under this category.
