Buyer: DEFRA NETWORK ETENDERING PORTAL Current stage: Tender OCID: ocds-b5fd17-308e91b1-3929-418e-b7e4-6b31203de8f6 [View canonical contract page](https://d3tenders.com/contract/?ocid=ocds-b5fd17-308e91b1-3929-418e-b7e4-6b31203de8f6) [Download OCDS JSON](https://d3tenders.com/contract/ocds-b5fd17-308e91b1-3929-418e-b7e4-6b31203de8f6.json) ## Summary The procurement process is initiated by the Defra Network eTendering Portal, seeking to conduct a review of the Reports of the Groups of Experts on Cryptosporidium in Water Supplies, along with the publication of additional guidance. This tender falls under the category of surface water treatment services and has a location based in London, United Kingdom. Currently in the tender stage, this opportunity is open until 12:00 on 23rd May 2022. Contract performance is expected to commence from 13th June 2022 and continue until 14th June 2023, with the procurement method classified as open under the open procedure (below threshold). This tender presents significant opportunities for businesses involved in water safety, treatment processes, and environmental monitoring, particularly small and medium-sized enterprises (SMEs) and voluntary, community, and social enterprises (VCSEs). Companies with expertise in cryptosporidium management, water treatment technologies, and environmental safety measures would be especially well-suited to compete. This is a prime opportunity for businesses looking to expand their reach in the public procurement landscape while contributing to the advancement of water safety practices. ## Notice Research Aims and Objectives To review the guidance and advice provided in the three reports of the Groups of Experts on Cryptosporidium in Water Supplies and identify whether any of the published guidance should be updated in the light of waterborne outbreaks of human cryptosporidiosis and other cryptosporidium-related water supply incidents that have occurred since the third report was published in 1998. In particular the review should consider guidance and recommendations covering: i. The occurrence of cryptosporidium in the environment and drinking water safety planning. ii. Species of cryptosporidium that are pathogenic to humans, their occurrence in the environment and concentrations in drinking water likely to cause illness. iii. The impact of raw water storage on the attenuation of cryptosporidium, risks associated with sources of cryptosporidium in catchments (for example human sewage discharges and animal husbandry) and short circuiting in reservoirs. iv. Water treatment processes that remove or inactivate cryptosporidium, optimisation of these processes and operational good practice. In particular recent developments in water treatment, for example membrane technology, UV treatment and enhanced coagulation/clarification processes (e.g. CoCoDAF/ moving bed/ Actiflow filters/ cartridge filters). v. Provision of continuous online monitoring of raw waters, final treated water and after intermediate stages of water treatment processes for turbidity and other relevant parameters, and triggers for response. vi. Protection of treated water storage tanks from contamination, taking into account risks present in the environment and risks associated with severe weather events. vii. Protection of water supply assets, in particular open structures containing partially treated water such as slow sand filters, from avian and mammalian access. viii. Sampling methods for cryptosporidium and oocyst recovery for different sampling methods for raw and treated water ## Key Details | Field | Value | | --- | --- | | Publication source | Contracts Finder | | Latest notice | https://www.contractsfinder.service.gov.uk/Notice/c4eecaaf-0ced-48db-afb9-f5b1ef7be787 | | Notice type | Tender Notice | | Procurement type | Standard | | Procurement category | Services | | Procurement method | Open | | Procurement method details | Open procedure (below threshold) | | Tender suitability | SME, VCSE | | Awardee scale | Not specified | | All stages | Tender | ## Dates | Field | Value | | --- | --- | | Publication date | 14 Apr 2022 | | Submission deadline | 23 May 2022 | | Future notice date | Not specified | | Award date | Not specified | | Contract period | 12 Jun 2022 - 14 Jun 2023 | | 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 - 90 - Sewage, refuse, cleaning and environmental services ### Codes - 90733400 - Surface water treatment services ## Release History - 14 Apr 2022 at 12:41 - Tender - Tender Notice - https://www.contractsfinder.service.gov.uk/Notice/c4eecaaf-0ced-48db-afb9-f5b1ef7be787 ## Documents - https://www.contractsfinder.service.gov.uk/Notice/c4eecaaf-0ced-48db-afb9-f5b1ef7be787 14th April 2022 - Opportunity notice on Contracts Finder - https://www.contractsfinder.service.gov.uk/Notice/Attachment/9e5bddc1-38c1-454a-bd5d-b84eaef27954 n/a - https://defra.bravosolution.co.uk Link to eSourcing Portal ## Notice URLs - http://defra.bravosolutions.co.uk ## Provenance This Markdown file is an alternate public rendering of the D3 Tenders contract record.
