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(1) of The Private Water Supplies (England) Regulations 2016 http://www.legislation.gov.uk/uksi/2016/618/contents/made 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 (1) of the Private Water Supplies (England) Regulations 2016 and Regulation 4A of the Private Water Supplies (Wales) (Amendment) (No. 2) 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/approved-products/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, within water distribution systems and up to the point of delivery to premises.
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
UNCONTROLLED IF PRINTED 4 Issue date: November 2017
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.
UNCONTROLLED IF PRINTED 5 Issue date: November 2017
CRITERIA FOR INCLUSION ON TRANSITIONAL LIST FOR USE IN PRIVATE WATER SUPPLIES
Regulation 5(1) of the Private Water Supplies Regulations 2016 requires that any product or substance used in the preparation or distribution of a private supply or impurities associated with such products or substances, must not be present in water at the point of use at levels that would make it unwholesome or constitute a potential danger to human health. Regulation 4A of the Private Water Supplies (Wales) (Amendment) (No. 2) Regulations 2010 also states that any product or substance used must be one that would be permitted to be used in a water supply under Regulation 31 of the Water Supply (Water Quality) Regulations 2010 Products or substances used after the coming into force of these Regulations must either:
• be permitted to be used in a water supply under Regulation 31 of the Water Supply (Water Quality) Regulations 2000
• hold a product approval from WRAS • be covered by a current BS EN for treatment chemicals and products • be covered by Regulation 31(4)(b) of the Water Supply (Water Quality)
Regulations 2016 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.

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 2016, and hence under Regulation 5 of the Private Water Supplies (Regulation 4A in Wales). Regulation 31(4)(b) of the Water Supply (Water Quality) Regulations 2016 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.
PRODUCTS LIKELY TO FALL INTO REGULATION 31(4)(B)
• Aerators, agitators and stirrers • Back-flow prevention systems • Couplings/joints for pipes, gaskets and jointing compounds and other
components used with pipes and/or assembled products, e.g. in pressure vessels
• Crack injection sealants (not applied to the water contact surface of water retaining concrete structures)
• Expansion joint filler boards • Expansion joint sealants (excluding overbandaging products) • External pipe fittings, e.g. repair collars etc • Hydrants and associated fittings • In-situ sensors and probes (including pressure transducers and level
sensors), together with their cable coverings • Intake screens and strainers
UNCONTROLLED IF PRINTED 29 Issue date: November 2017
• Ladders and submerged gratings and walkways • Pumps and associated fittings and materials, including lubricants • Resin & chemical anchors • Rubber sealing rings for use with water pipelines or in assembled products,
e.g. pressure vessels – see Section 3.1, including Important Note “ii”. • Solvent welded plastics components (see section 5.6) • Static mixers • Some Surge vessel elastomeric liners • Taps • Touch-up coatings, e.g. associated with pipe welds and other factory coated
products etc. • UV disinfection systems components • Valves (including penstock and butterfly valves) and their lubricants • Water stops incorporated into concrete constructions • Water meters and associated fittings • Weir plates
UNCONTROLLED IF PRINTED 30 Issue date: November 2017
BRITISH STANDARDS BS EN FOR CHEMICALS AND MEDIA USED FOR TREATMENT OF WATER Chemicals and media used for treatment of water not covered under Regulation 31 or Regulation 5 must be covered by an appropriate BS:EN standard. A full list may be found in the current Secretary of State list at: http://www.dwi.gov.uk/drinking-water-products/approved-products/Annex2.pdf
