Summary of the contracting process

Severn Trent Water Limited is currently in the planning stage for the procurement titled "Procurement of Tank Covers," focusing on the utility industry category. This project involves the supply and installation of covers for Asp (Activated Sludge Plant) tanks across up to 23 sewage treatment works in various regions of the United Kingdom. The procurement aims to capture gas emissions effectively, requiring solutions that can handle air pressure fluctuations. The engagement process for this project has been extended, allowing market research activities to continue until the 30th of April 2026. This market engagement is part of Severn Trent's efforts to refine their requirements and inform the sourcing strategy, with the intention of entering into a framework agreement potentially starting from December 2026, with a contract period lasting until March 2030, and the possibility of renewal.

This tender offers significant opportunities for businesses specialising in roofing materials, purification plant equipment, roof works, and special trade construction works. Companies with expertise in designing and installing tank covers that can manage gas emissions while maintaining airtight conditions will find this project particularly suitable. By engaging with Severn Trent in the early stages, businesses can help shape the potential specifications and sourcing strategies, thus positioning themselves as preferred partners. This opportunity is ideal for businesses looking to expand their footprint in the utilities sector and to form long-term collaborative relationships with a major private utility buyer in the UK.

Notice Title

Procurement of Tank Covers

Notice Description

Severn Trent are currently investigating the potential procurement of supply and installation of covers for a range of ASP (Activated Sludge Plant) tanks at up to 23 of our sewage treatment works with some sites having multiple ASP assets. Severn Trent is also considering the procurement of covers for its Liquor Treatment Plants. The intention is to collaboratively work together with supplier(s) to identify the best solution for our sites. The purpose of the cover is to capture gas emissions from the mixed liquors in the tank, which constantly receives aeration with high airflow. We require covers that can deal with air pressure and cope with a certain level of pressure fluctuation. As such the cover should be sealed to the tank and reasonable steps should be taken to minimise the leakage of gas. It is expected that extraction points will be required to remove the gas for processing.
