Enhancing Stormwater Capacity

Over the last ten months, our specialist teams at GVG Group have been working in collaboration with Avove Utilities on behalf of Severn Trent, delivering a major programme of improvements to enhance the region’s existing sewage network.

Expanding Capacity and Protecting Local Watercourses

The project involved the development and installation of over 100 new storage tanks, adding approximately 10,000m³ of additional capacity to the existing system.

Each tank has been carefully designed to capture excess flows during storm events, preventing spills and safeguarding local watercourses from pollution. This increased capacity will play a vital role in improving network resilience and supporting Severn Trent’s ongoing commitment to creating cleaner rivers and a healthier environment.

Fast, Efficient Delivery

Our teams have delivered these works with exceptional efficiency, completing multiple complex installations across the network within tight timescales.

The time-lapse video below showcases our most recent and largest project to date — an installation adding 1,100m³ of new storage completed in just five weeks from start to finish.
