Procurement of N2O Emissions Treatment Solutions and Other Treatment Solutoions

Tender description

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.
