This procurement, classified under the services category with a focus on drinking water, is currently at the Tender stage. It follows an open procedure above threshold, and the tender period concludes on 19 April 2022, with the contract expected to commence on 17 May 2022 and run until 17 December 2022. This tender offers significant opportunities for businesses specialising in water treatment technologies and environmental services, particularly those involved in disinfection and water quality management. Companies that are small and medium-sized enterprises (SMEs) or voluntary, community, and social enterprises (VCSEs) are particularly encouraged to participate, as the project aims to develop standards and guidance that are vital for both public and private water suppliers in the UK. ## Notice The aim of this project is to develop a validation standard for ultraviolet (UV) irradiation for disinfection and update existing guidance on the use of UV for water treatment. The Drinking Water Inspectorate published guidance on the use of UV irradiation for the disinfection of public water supplies in 2010, and this guidance was reviewed and updated in 2016. The guidance and validation standard is intended for use primarily by public and private water suppliers within the UK. The current guidance document provides information on the design, operation and monitoring of UV irradiation as a process for the disinfection of public water supplies intended for domestic or food production purposes. The guidance may also be appropriate to the disinfection of waters analogous to public water supplies, such as unregulated or private water supplies. The objectives are: 1. Conduct a review of current US and European validation standards and verification techniques. Search the grey and published literature for up to date evidence on the use of UV irradiation for the disinfection of public and private water supplies, including an evaluation of good operational practice. 2. Develop a prospective UK validation standard that can be used when installing small or large UV disinfection systems (public and private water supplies). 3. Amend the current DWI guidance, to maintain up to date technical relevance and ensure that the guidance is consistent and fit for purpose. ## Key Details | Field | Value | | --- | --- | | Publication source | Contracts Finder | | Latest notice | https://www.contractsfinder.service.gov.uk/Notice/b856c4d9-e0f5-4bd6-b45c-0adc3f8bea09 | | Notice type | Tender Notice | | Procurement type | Standard | | Procurement category | Services | | Procurement method | Open | | Procurement method details | Open procedure (above threshold) | | Tender suitability | SME, VCSE | | Awardee scale | Not specified | | All stages | Tender | ## Dates | Field | Value | | --- | --- | | Publication date | 31 Mar 2022 | | Submission deadline | 27 Apr 2022 | | Future notice date | Not specified | | Award date | Not specified | | Contract period | 23 May 2022 - 24 Dec 2022 | | Recurrence | Not specified | ## Values | Field | Value | | --- | --- | | Tender value | Not specified | | Lots value | Not specified | | Awards value | Not specified | | Contracts value | Not specified | ## Status | Field | Value | | --- | --- | | Tender status | Active | | Lots status | Not specified | | Awards status | Not specified | | Contracts status | Not specified | ## Buyer | Field | Value | | --- | --- | | Main buyer | DEFRA NETWORK ETENDERING PORTAL | | Locality | LONDON | | Post town | South West London | | Postcode | SW1P 3JR | | Country | England | | ITL 1 | TLI London | | ITL 2 | TLI3 Inner London - West | | ITL 3 | TLI35 Westminster and City of London | | Local authority | Westminster | | Electoral ward | St James's | | Westminster constituency | Cities of London and Westminster | | Delivery location | TLI London | ## CPV Codes ### Divisions - 41 - Collected and purified water ### Codes - 41110000 - Drinking water ## Release History - 31 Mar 2022 at 14:39 - TenderAmendment - Tender Notice - https://www.contractsfinder.service.gov.uk/Notice/b856c4d9-e0f5-4bd6-b45c-0adc3f8bea09 - 22 Mar 2022 at 15:43 - TenderAmendment - Tender Notice - https://www.contractsfinder.service.gov.uk/Notice/b856c4d9-e0f5-4bd6-b45c-0adc3f8bea09 - 22 Mar 2022 at 15:42 - Tender - Tender Notice - https://www.contractsfinder.service.gov.uk/Notice/b856c4d9-e0f5-4bd6-b45c-0adc3f8bea09 ## Documents - https://www.contractsfinder.service.gov.uk/Notice/b856c4d9-e0f5-4bd6-b45c-0adc3f8bea09 31st March 2022 - Opportunity notice on Contracts Finder - https://www.contractsfinder.service.gov.uk/Notice/Attachment/7295bb54-9d1b-4e5e-a4cf-07f6ce3f5e25 n/a - https://defra.bravosolution.co.uk Link to eSourcing Portal - https://www.contractsfinder.service.gov.uk/Notice/Attachment/bc8be1b3-bbeb-47b3-be60-fd397875e1fb n/a - https://www.contractsfinder.service.gov.uk/Notice/Attachment/643a548c-6236-4c76-a1f0-539ff24b9d29 n/a ## Provenance This Markdown file is an alternate public rendering of the D3 Tenders contract record.
