This initiative falls within the 'works' category and targets the private utility sector, specifically focusing on sewage digesters and wastewater treatment plant construction work. The planned project is intended to be located in regions UKI and UKJ in the United Kingdom. According to the timeline, the engagement with potential suppliers is scheduled to conclude by 28 April 2026. The procurement process is part of Thames Water's aim to support its environmental and waste management goals, which includes converting sewage into renewable energy. The procurement method involves a preliminary market engagement to inform future decisions. This tender presents significant opportunities for businesses in the engineering, bioenergy, and environmental technology sectors. Firms with expertise in anaerobic wastewater treatment and sustainable resource recovery solutions will find this project particularly relevant. By engaging in this project, companies can expand their footprint in the evolving bioresource industry and contribute to critical innovation in the utilities sector. Technological providers, engineering consultants, and integrators are well-suited to compete, particularly those with innovative technologies and performance approaches. Participation in this market engagement could position businesses as frontrunners for future formal procurement activities by Thames Water, offering potential for substantial growth in capabilities and market presence. ## Notice Thames Water is undertaking early market engagement to inform a potential future procurement for the design, construction, commissioning, and operation of a new Anaerobic Wastewater Treatment system. The purpose of this notice is to gauge market interest, understand current capability, and gather insight from suppliers with relevant expertise in delivering sustainable bioenergy, waste-processing, and resource recovery solutions. The proposed Anaerobic Wastewater Treatment plant will support Thames Water in achieving its environmental, waste management, and decarbonisation objectives by converting crude sewage into renewable energy and potential nutrient products. As we develop our commercial strategy and technical specification for Anaerobic Wastewater Treatment systems, we are seeking feedback from experienced operators, technology providers, engineering consultants, and integrators with expertise of anaerobic wastewater treatment and wider bioresource sector. This engagement is not a call for competition and does not formally commence any procurement process. Instead, it aims to: * Test the level of market capacity and interest in the forthcoming opportunity * Explore innovative technologies, delivery models, and performance approaches * Identify potential risks, dependencies, and considerations for project design * Inform Thames Water's decision making ahead of any formal procurement activity Suppliers who express interest may be invited to participate in market engagement sessions, questionnaires, or one to one discussions. All feedback received will be used solely to shape the Authority's future strategy ### Planning Information If you want access to the Market Engagement materials related to this project, please fill out this form: https://forms.office.com/e/ML4DNK3c3W ## Key Details | Field | Value | | --- | --- | | Publication source | Find A Tender Service | | Latest notice | https://www.find-tender.service.gov.uk/Notice/031594-2026 | | Notice type | UK2 - Preliminary Market Engagement Notice | | Procurement type | Standard | | Procurement category | Works | | Procurement method | Not Specified | | Procurement method details | Not specified | | Tender suitability | Not specified | | Awardee scale | Not specified | | All stages | Planning | ## Dates | Field | Value | | --- | --- | | Publication date | 7 Apr 2026 | | Submission deadline | Not specified | | Future notice date | 28 Apr 2026 | | Award date | Not specified | | Contract period | 19 May 2026 - 28 Feb 2028 | | 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 | Planning | | Lots status | Planning | | Awards status | Not specified | | Contracts status | Not specified | ## Buyer | Field | Value | | --- | --- | | Main buyer | THAMES WATER UTILITIES LIMITED | | Locality | READING | | Post town | Reading | | Postcode | RG1 8DB | | Country | England | | ITL 1 | TLJ South East (England) | | ITL 2 | TLJ1 Berkshire, Buckinghamshire and Oxfordshire | | ITL 3 | TLJ16 Berkshire West | | Local authority | Reading | | Electoral ward | Thames | | Westminster constituency | Reading Central | | Delivery location | TLI London, TLJ South East (England) | ## CPV Codes ### Divisions - 45 - Construction work ### Codes - 45252122 - Sewage digesters - 45252127 - Wastewater treatment plant construction work - 45252130 - Sewage plant equipment ## Release History - 7 Apr 2026 at 14:59 - Planning - UK2 - Preliminary Market Engagement Notice - https://www.find-tender.service.gov.uk/Notice/031594-2026 ## Documents - https://www.find-tender.service.gov.uk/Notice/031594-2026 7th April 2026 - Preliminary market engagement notice on Find a Tender ## Notice URLs - https://forms.office.com/e/ML4DNK3c3W - https://www.legislation.gov.uk/ukpga/2023/54/contents ## Provenance This Markdown file is an alternate public rendering of the D3 Tenders contract record.
