UK2 - Preliminary Market Engagement Notice
Summary of the contracting process

Severn Trent Water Limited, a private utility company based in Coventry, United Kingdom, is in the planning stage of a procurement process for "Active Gas Capture (Digested Sludge Degassing) Solutions." This project falls under the category of machinery for the treatment of sewage and targets multiple UK regions, including UKC, UKD, UKE, UKF, UKG, UKH, UKI, UKJ, and UKK. The aim is to implement technological solutions that enhance the methane recovery potential of anaerobic digestion plants as part of Severn Trent's net-zero enhancement investment strategy. Key milestones include a market engagement notice published on 3rd October 2025, with interested suppliers required to complete a form by 7th November 2025.

This tender represents a substantial opportunity for growth in the utilities sector, particularly for businesses specializing in environmental and waste management technologies. Companies with expertise in supply, installation, and commissioning of degassing systems, and those capable of proving past industry experience, will find this project particularly relevant. Additionally, businesses offering solutions compliant with European and British engineering standards could gain long-term collaborative opportunities with Severn Trent Water Limited, spanning from mid-2026 onwards.

Notice Information

Notice Title

Active Gas Capture (Digested Sludge Degassing) Solutions

Notice Description

Active gas capture is one of the Severn Trent net-zero enhancement investment solutions for reducing Bioresources methane emissions during AMP8. To meet our regulatory commitments on operational emissions reduction, we are seeking technological solutions that enhance the methane recovery potential of anaerobic digestion plants. Specifically, we are looking to the market for technologies such as vacuum degassing that target the removal of residual biogas, entrained or dissolved in liquid digestate, reducing subsequent downstream methane emissions to atmosphere. We would be looking for supply, installation & commissioning of such solution across various Severn Trent Water sites (likely to be required on site from 2027 onwards). Training, Operations & Maintenance may also be required (but to be determined at a later stage following further discussions). Preliminary discussions indicate that c.18 sites may require an active gas capture solution. The following requirements state our performance and site integration expectations and standards compliance for a proven technological solution which removes biogas from digested sludge via degassing or other: GENERAL: - A complete containerised or roof-covered solution that removes and captures biogas (dissolved and entrained in microbubbles) from within the solid and liquid matrix of digested sludge. - A solution which recovers the captured biogas into an existing biogas collection system or other beneficial-use outlet. SAFE SYSTEM INTEGRATION: - Integrates with the outlet of an existing digester(s) or covered post digestion tank(s) - Integrates into the existing biogas collection pipework - Integrates into the existing site SCADA systems - Meets all requirements of the Dangerous Substances and Explosive Atmospheres Regulations (DSEAR) and the Severn Trent Potentially Explosive Atmospheres Design Manual and Specification (ME37-Potentially Explosive Atmospheres), including details on explosion protection. TECHNOLOGY READINESS LEVEL (TRL): - At TRL 8 or above CASE STUDIES / INDUSTRY EXPERIENCE: - Able to provide at least one case study specific to trials / installations recovering biogas from digested sewage sludge or material with similar properties HARDWARE & SOFTWARE: - Compliance with Severn Trent mandated supply frameworks, some components may require replacement to Severn Trent approved framework suppliers (further details of impacted components to be provided by Severn Trent at a later stage). - Hardwired interlocks for gas-related DSEAR safety. EMISSIONS MONITORING: - Internal capability or compatibility with monitoring equipment measuring the concentration and flowrate of biogas, methane and oxygen ENGINEERING STANDARDS: - The complete system and its components developed to European (EN) / British or equivalent / Water Industry Specification / Severn Trent engineering standards, with suppliers to advise of any potential asset standard deviations known at this stage. Interested Suppliers are requested to complete the below form ahead of the proposed engagement deadline of 7th November 2025: https://forms.office.com/e/Jeq86303pd
