About us

Our businesses

The Severn Trent family spans several companies. Here's how they all connect

Where we operate

Severn Trent provides water and waste water services for a proportion of England and Hafren Dyfrdwy provides water for part of Wales. On the map, the white area represents the Severn Trent boundaries and the green area highlights the Hafren Dyfrdwy region.

The grey area represents the region in which Severn Trent provides waste water services only, and South Staffordshire Water provide the water services.

Severn Trent Water

We’ve recently launched a new Community Fund which will share millions of pounds with community groups and initiatives across our region.

Ten of our reservoir sites are open to visitors, offering everyone the chance to walk or cycle round and to enjoy the surroundings that we look after on behalf of future generations.

In 2019 we were ranked as one of Glassdoor's top 50 places to work in the UK, as ranked by our own people.


Hafren Dyfrdwy

Our investment plans will see us pumping £124m into our water network and £28m into our waste sites between 2020 and 2025, while maintaining the lowest average combined bill in Wales.

We have visitor sites at Lakes Vyrnwy, Clywedog and Pendinas that attract thousands of visitors every year.


Severn Trent Business Services

Business Services is our non-regulated business offering a range of services to municipal and industrial clients, including the Ministry of Defence and the Coal Authority, for design, build and operation of water and wastewater treatment facilities and networks. 

The business also generates renewable energy from anaerobic digestion, wind turbines, solar panels and hydro schemes.

We’ve also expanded into the food waste market, owning and operating a number of facilities from Derbyshire to South Wales.

The Property Development arm of our business generates value by developing excess land in the regulated business before selling to external parties, sharing the profits with Severn Trent Water customers.
