The procurement aims to address greenhouse gas emissions from nitrous oxide at 23 wastewater treatment sites and forms part of the wider Cover and Treat solution within the company’s Net Zero investments Programme. Interested parties are invited to engage with the initiated market engagement process, with deadlines for feedback set for 5th June 2026. The procurement will be conducted as a utility procurement above threshold with the potential establishment of a framework agreement. This procurement offers significant opportunities for businesses specialising in environmental solutions and engineering, particularly those with expertise in greenhouse gas treatment and machinery manufacturing. Companies can leverage this engagement to potentially secure contracts in a high-impact area focused on sustainability and regulatory compliance. The process is suited to businesses that can provide integrated solutions compatible with existing infrastructure, especially those capable of operating under framework agreements and delivering innovative, efficient technologies to support Severn Trent Water’s environmental goals. ## Notice Severn Trent Water (STW) are currently investigating the potential procurement of an N2O emissions treatment solution as part of its broader Cover and Treat solution and its Net Zero investments Programme, which forms part of STW's AMP8 regulatory commitments. The purpose of the treatment solution is to extract the air containing greenhouse gas emissions arising from nitrous oxide (N2O) from our ASP tanks and convert these harmful gases into harmless gases. There may be other requirements to treat other gases in future, potentially from other types of process. The tank cover element of Cover and Treat is expected to be procured separately to the required extraction and treatment system for all 23 waste water treatment sites in scope of this programme. In all cases the emissions treatment solution will need to interface with the cover however due to sequencing in the procurement timeline, the separate procurements could mean that the tank covers will be fitted before procurement of the treatment solution is complete. In this case the emissions treatment solution must integrate into the newly-installed tank covers without their removal. ### Planning Information STW is initiating this market engagement to help shape its future procurement approach.
