STW Process Emissions Monitoring Devices

Tender description

STW are seeking to install continuous monitoring at eight wastewater treatment works to monitor and quantify nitrous oxide monitoring. The organic material removed from wastewater treatment process is used to generate biogas on circa 20 sites. Fugitive methane emissions resulting from leaks across this process have been identified as a key contributor to overall site GHG emissions. However, there are also open processes and storage which are expected to continuously emit methane. STW are also looking to install continuous methane monitoring at three biogas production sites in order to quantify total emissions as well as locate leaks. The purpose of the soft market testing is to understand commercially available products and services for monitoring and quantifying GHG emissions. We request that participants consider the following: 1. Solutions should be deliverable now with no further development required 2. We want to look at solutions for the full suite of our asset base from large urban sites to small rural applications Lot 1: Severn Trent have committed to a Triple Pledge of net carbon zero, 100% renewable electricity and 100% electric fleet by 2030. In addition to this, STW have also signed up to science-based targets. As part of the net carbon zero and science based target pledges STW are inviting companies to come forward with new ideas that will help locate, monitor & quantify both continuous and fugitive greenhouse gas (GHG) emissions; specifically methane (CH4) and nitrous oxide (N2O) from wastewater treatment and biogas production facilities. ST, which serves eight million people across the Midlands and mid-Wales. There are c1000 wastewater treatment works which utilises biological processes to break down ammonia. These include activated sludge plants (ASP), rotating biological contactors (RBC), trickling filters/ biofilters. Nitrous oxide can be a biproduct of these biological processes. STW are interested in understanding how emissions from these processes can be quantified.
