Challenge

Severn Trent Water Ltd (STWL) is a regulated business with responsibilities for the provision of water and sewage services to over 8 million people in an area stretching from the Severn Estuary to the mouth of the Humber.

Severn Trent Water Ltd constructed two aerobic treatment units (ATUs) at an existing sewage treatment works. The ATUs were required as part of wider asset maintenance works being undertaken to expand wastewater treatment capacity in the Melbourne area of Derbyshire.

The wider works comprised the installation of 4 new Submerged Aerated Filters (SAFs) to replace the existing High Rate Filter (HRF) which was underperforming. The performance problems with the HRF were causing the works to operate at the top end of the consents limit set by the Environment Agency, with a high possibility of failures.

Solution

Random biological filter media from Warden Biomedia were chosen to provide ultra-efficient and cost-effective aerobic treatment in the new ATUs for Severn Trent Water. The aerated treatment units were manufactured and supplied by Haith Industrial. 

Outcome

David Evans, Project Manager at Haith Industrial said, "The Warden biomedia were a natural choice for this project as they have high efficiency rates and are also very cost-effective and long-lasting."
