Summary of the contracting process

Severn Trent Water Limited is planning the procurement of covers for Activated Sludge Plant (ASP) tanks and Liquor Treatment Plants across 23 sewage treatment sites in the United Kingdom. The procurement process is currently in the planning stage, with a focus on engaging potential suppliers through market engagement strategies. Interested suppliers are invited to complete a questionnaire by 31 March 2026, to aid in refining the procurement approach. The project aims at capturing gas emissions efficiently, requiring tank covers that withstand pressure fluctuations and minimise gas leakage.

This procurement presents substantial opportunities for businesses in industries relating to roofing materials, purification plant equipment, and tanks and containers. Firms capable of providing innovative solutions for sealing tank covers with extraction points for gas processing will find this tender suitable for growth. The procurement method includes a framework agreement, and the contract period for the award is set to commence from 1 December 2026, potentially extending until March 2034. Companies with expertise in the utilities sector would benefit greatly from exploring this opportunity to collaborate with Severn Trent Water on this environmental initiative.

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.
