IMPORTANT NOTES
1. This form should be used for applications for the approval of membrane filtration & water treatment
units under the appropriate regulations within the United Kingdom 1. Separate forms are available from
our website for other product types, including pipe systems & site applied products –
http://www.dwi.gov.uk/drinking-water-products/advice-and-approval/index.htm
. Separate forms are available for other products – http://www.dwi.gov.uk/drinking-water-products/adviceand-approval/index.htm
This form should not be used for the following types of filter –
1) Depth filters – most of the filtration media used for these filters, e.g. sand, granular activated
carbon (GAC), are covered by published BS EN standards – see section 2.2 of Annex 2 of the
“List of Approved Products” (http://www.dwi.gov.uk/drinking-water-products/advice-andapproval/index.htm).
2) Course (screening) filters – typically these will be used as pre-filters to remove particulate matter
from water – each of the non-metallic components of the filter housing and of the filter medium
(membrane) should meet the normal requirements of Regulation 31 – see Advice Sheet 1
(http://www.dwi.gov.uk/31/drinking-water-products/advice-and-approval/Advicesheet1.pdf).
3) Mechanical filters, e.g. centrifugal filters, screens – each of the non-metallic components of the
filter housing and of the filter screen/disks should meet the normal requirements of Regulation 31
– see Advice Sheet 1 – http://www.dwi.gov.uk/31/drinking-water-products/advice-andapproval/Advicesheet1.pdf.
2. Before you start completing this form, please read the advice for applicants given in Advice
Sheets Numbers 1,2 and 6 (available from our website - http://www.dwi.gov.uk/drinking-waterproducts/advice-and-approval/index.htm), together with the information in the shaded boxes – this is
here to help you. If you fail to provide all the information necessary it is likely that your
application will be delayed.
3. We can only consider products that are offered for sale to UK public or private drinking water
suppliers and will be used by them in the provision of drinking water supplies. Unlike the Water
1
Regulation 31 of the Water Supply (Water Quality) Regulations 2016/2010 (England & Wales). There are
separate legislative and approval processes for Scotland and Northern Ireland, but the Drinking Water Inspectorate
carries out the approval process for the whole of the United Kingdom. Further information on regional requirements
can be obtained from the Drinking Water Quality Regulator for Scotland ( PO Box 23598, Edinburgh EH6 6WW or
e-mail [email protected]), or from Chief Inspector of Drinking Water for Northern Ireland ( DWI (NI), Northern
Ireland Environment Agency, Klondyke Building, Gasworks Business Site, Belfast, BT7 2JA or e-mail to
[email protected] ). These three organisations are collectively referred to as “the Authorities”.

5. EVIDENCE OF THE PRODUCT’S EFFECT ON WATER QUALITY (BS 6920)
IMPORTANT NOTES
1. DWI uses the results of BS 6920 testing (or equivalent) as a means of pre-screening a product’s
effects on water quality. This information is normally required BEFORE the DWI can specify any further
tests that will be required. BS6920 test reports must meet the requirements set out in Annexes B and C of
Advice Sheet 1 - http://www.dwi.gov.uk/31/drinking-water-products/advice-and-approval/Advicesheet1.pdf
2. For each non-metallic material included in your product you need to supply a report showing conformity
with the current BS 6920 (Suitability of non-metallic products for use in contact with water intended for
human consumption with regard to their effect on the quality of the water) test requirements.
Notes:
- approval/reports are valid for 5 years – after this period the DWI will require evidence of continuing conformity.
- copies of equivalent European test reports can be considered but applicants must provide copies of test reports (in
English); a copy of the test certificate alone will not suffice. For more advice on the reporting requirement please
see Annex D of Test Protocol 1 - http://www.dwi.gov.uk/drinking-water-products/advice-and-approval/protocol1.pdf
3. Test conditions used for the BS 6920 testing (or equivalent European testing) must be relevant to all the
uses for which approval is being sought.
In some instances, this may necessitate doing BS 6920 testing (or equivalent) under more than one set of
conditions. Alternatively, one set of test conditions may be considered sufficient, provided that the DWI is
satisfied that these conditions represent the worst case in relation to the proposed use. Please contact
Regulations 31 Enquiries (DWI) for further advice.
4. You may have to contact your suppliers to obtain copies of the appropriate test reports.
5. DWI reserves the right to request additional BS 6920 testing.
Please list the BS 6920 (or equivalent) reports being submitted in support of this application.

7.1 Product formulation details
With this application you are asked to provide certain information, some of which you may
regard as confidential. DWI will need to copy parts of this information to its appointed analysts
and possibly other colleagues for the purposes of the application and cannot process the
application unless you agree to its doing so. Therefore please give your consent (see Section
7.3 below) to DWI’s passing this material to DWI’s partner analyst and any other DWI
colleague who, in DWI’s reasonable opinion, needs to see it to carry out a function necessary
to process the application. Your consent on this application form will be taken to override any
standard disclaimer in any email message from you that is inconsistent with this requirement.
DWI and its analysts and colleagues will take all reasonable care to preserve the
confidentiality of your material.
NOTES:
1. if you do not consent as above, DWI cannot process your application
2. DWI cannot enter into a confidentiality agreement with either yourselves or your suppliers – see
http://www.dwi.gov.uk/drinking-water-products/faqs/FAQ3.pdf for further information.
3 DWI may also require a third party (for example, a manufacturer of an ingredient or raw material used
in the manufacture of your product) to provide confidential information. If such a third party refuses to
provide information, it may not be possible to process your application.
4 Most delays associated with applications are due to inadequate product information or supporting
Instructions for Use in the initial application documents, or reluctance or unwillingness of applicant
suppliers to submit confidential formulation information to the Inspectorate. The Inspectorate cannot
accept any responsibilities for delays caused by these issues.
