APPLICATION FORM: CHEMICALS FOR USE WITH DRINKING WATER
COMMERCIAL IN CONFIDENCE
Please complete the first two lines of this table – the last line is for DWI use only
Your organisation
Name of your product
* Reference Number : DWI 56.4.
Date received by the DWI :
* - this number will be assigned to your product once DWI has received your completed form.
IMPORTANT NOTES
1. This form should be used for applications for the approval of chemicals for use with water intended for human
consumption 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-waterproducts/advice-and-approval/index.htm Separate forms are available from our website for other product types,
including chemical additives for use with water treatment systems – http://www.dwi.gov.uk/drinking-waterproducts/advice-and-approval/index.htm
2. 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 Regulations Advisory Scheme we
cannot consider for approval products used in building water systems, or approve materials in isolation from their end
use.
3. Many chemicals are now covered by published European Standards (ENs). You should note that DWI can no longer
accept applications for approval of any product that consist of a single substance covered by an appropriate published
EN standard. Products containing more than one substance, covered by appropriate BS EN standards are, however,
subject to consideration by the Drinking Water Inspectorate.
4. Approval of biocides is now handled by the Health and Safety Executive (HSE); therefore DWI can no longer accept
applications for approval of products containing biocidal substances. Biocidal products in contact with drinking water do
require approval if not covered by an appropriate BS EN standard.
5. Before you start completing this form, please read Advice Sheets Numbers 1,2 and 3 (available from our website - –
http://www.dwi.gov.uk/drinking-water-products/advice-and-approval/index.htm), together with the information in the
shaded boxes. If you fail to provide all the information necessary it is likely that your application will be delayed.
6. Please make sure you clearly mark any supporting information with the name of your organisation and the name of
the product(s). Once allocated, always use the DWI reference no. in relation to this application for your product.
7. You must accept the responsibility for ensuring that ALL information required has been sent to us, either by yourself
or directly by your suppliers. Incomplete applications will be returned to you for amendment and will not be considered
by DWI until ALL the required information has been received. DWI cannot process incomplete applications.
8. Please e-mail the completed form, as an MS Word ® document, to Reg31.enquiries@defra.gsi.gov.uk, together will
the Instructions for Use documentation and other supporting information. A scanned copy of the signed declaration
must be sent to the email address above.

Regulation 31 of the Water Supply (Water Quality) Regulations 2000/2001 (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
regulator@dwqr.org.uk), 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 dwi@doeni.gov.uk ).
These three organisations are collectively referred to as “the Authorities”.

1. Please complete copies of tables 5.1 and 5.2 for each material/component used in your test
product, taking into account the guidance on information requirements set out below..
2. If you intend to source a material/component from more than one supplier, make sure you
provide the details of ALL the alternatives you wish to use.
3. Please make sure you list ALL ingredients in each material – it is likely that you may not be able

ingredient formulations. Failure to provide this information will delay the processing of
your application.
6. For each product/material the list of ingredients should add up to 100%.
7. Approval is given on the basis that there will be no changes in the ingredients of the
product – both their nature and concentration. It is recognised, however, that for a minority

7 DECLARATION
Before we can process your application we need your signed acceptance of the
requirements and conditions set out below.
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 7.4 of this form) 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.
