Its main territories for Seven Trent and its north and mid-Wales water company Hafren Dyfrdwy plan to spend £2.5bn during the remaining AMP7 period.

Core capabilities required include civils, M&E, green solutions and pipelines with an increased emphasis on digital and innovation.

Severn Trent wants to hear expressions of interest from suppliers to support the delivery of a range of capital projects across wastewater and water treatment and pipelines, and its ambitious Green Recovery programme – a £566m scheme that aims to support the UK’s green economic recovery.

Hafren Dyfrdwy, which serves customers in and around Powys and Wrexham, wants to hear expressions of interest from suppliers to support the delivery of a variety of projects covering water and wastewater in both networks and treatment.

The largest programme of projects is within wastewater treatment covering the whole of Powys.  Hafren Dyfrdwy is particularly interested in hearing from local suppliers based in Wales and the Hafren Dyfrdwy area.

Helen Miles, capital delivery and commercial director for the Severn Trent group, said: “We’re on an exciting journey with big investment plans focussed on improving our environment.  We want to partner with local and national suppliers with a broad range of capabilities, from the smallest to the largest delivery partners.

“If you’re looking to grow your business with a reliable partner, want to leave a lasting legacy for generations to come or just want to be involved in some truly exciting projects, we want to hear from you.”

Severn Trent and Hafren Dyfrdwy will be launching their capital supplementary qualification system in March, which will be valid until the end of AMP 7 (31st March 2025).  Companies that want to register should email Seven Trent.
