Severn Trent, the trading name owned by the above company applies to a group of companies employing more than 15,000 people across the UK, US and mainland Europe, with some involvement in the Middle East.
The main companies in the group are Severn Trent Water and Severn Trent Services.
Severn Trent Laboratories was rebranded as part of Severn Trent Services in 2010 to streamline the company better and to give a single worldwide image, rather than a series of separate organisations with different identities.
As with all UK water companies, Severn Trent is regulated under the Water Industry Act 1991.

Severn Trent Water Authority was established in 1985 through the amalgamation of the pre-existing water supply authorities, the Severn River Authority, the Trent River Authority and the sewage and sewage disposal responsibilities of the councils within its area. In 1989, the authority was privatised under the Water Act 1973, together with the rest of the water industry in England and Wales, to form Severn Trent Water with a responsibility to supply fresh water and treat sewage for around 8 million people living in the Midlands of England and also a small area of Wales. It took its name from the two major rivers in this area, the Severn and the Trent. In 1991 it went on to acquire Biffa, a leading waste management business.
In October 2006 Biffa was demerged from the Severn Trent group and is now listed separately on the Stock Exchange. In January 2007 the American side of Severn Trent Laboratories was sold to HIG Capital. In September 2007 the company announced they would be closing their headquarters in the city of Birmingham and relocating to a custom built office complex in the centre of the city of Coventry in autumn 2010.
Statutory water undertakers acquired
The water authority took over the following public sector statutory water undertakers:
- Birmingham Corporation Water Department
- the water supply department of Coventry Corporation
- the water supply department of Leicester Corporation
- City of Nottingham Water Department
- the water supply department of Stafford Corporation
- the water supply department of Wolverhampton Corporation
- the water supply department of Cannock Rural District Council
- Central Nottinghamshire Water Board
- East Shropshire Water Board
- Montgomeryshire Water Board
- North Derbyshire Water Board
- North East Warwickshire Water Board
- North West Gloucestershire Water Board
- North West Leicestershire Water Board
- North West Worcestershire Water Board
- Rugby Joint Water Board
- South Derbyshire Water Board
- South Warwickshire Water Board
- South West Worcestershire Water Board
- Staffordshire Potteries Water Board
- West Shropshire Water Board
Section 12 of the Water Act 1973 stated that “where the area of a water authority includes the whole or part of the limits of supply of a statutory water company, the authority shall discharge their duties with respect to the supply of water within those limits through the company.” The following two private statutory water companies continued to supply water as before within their limits as supply but only as "agents" of the water authority:
- East Worcestershire Waterworks Company - as from 1 September 1993 the water undertaking of this company was transferred to Severn Trent as per The East Worcester and Severn Trent Water (Amendment of Local Enactments etc.) Order 1993 (S.I. 1993 No. 2130)
- South Staffordshire Waterworks Company
The water authority remained responsible for sewerage and sewage disposal within the limits of supply of these two companies.
Other organisations and functions acquired
The water authority took over the following public sector bulk water suppliers:
- Derwent Valley Water Board
- River Dove Water Board
The water authority took over the following main drainage authorities, which were joint boards set up to deal with the main sewerage and sewage treatment in their respective areas:
- Upper Tame Main Drainage Authority
- Upper Stour Main Drainage Authority
It took over two river authorities, responsible for control of water pollution:
- Trent River Authority
- Severn Trent Authority
The water authority took over the functions responsible for sewerage and sewage disposal from all local authorities, including main drainage authorities, within its area, however section 15 of the Water Act 1973 allowed district (but not county) councils to enter into agency agreements with water authorities whereby the district councils became their "agents" for the maintenance and design and construction of new sewers.
The company supplies about 3.7m households and businesses in its area. Severn Trent Water has a call centre in Coventry dealing with operational emergencies and billing enquiries, and two other call centres in Derby and Shrewsbury which deal solely with billing enquiries. Its head office is the new custom-built "Severn Trent Centre" in Coventry.
Regulation and criticism
Like other water companies in England, Severn Trent Water is regulated by OFWAT, the Water Services Regulation Authority.
High leakages rate 2008-11
In July 2008, OWAT confirmed that it had fined Severn Trent Water £35.8 million for deliberately providing false information to Ofwat and for delivering poor service to its customers.
In 2008 the Company was fined £2m (reduced from a previous judgement of £4m) for poor information reporting and covering up misleading leakage data.
Effect of the Summer 2007 United Kingdom floods
In July 2007 the Mythe Water Treatment Works near Tewkesbury became inundated with water from the River Severn during the Summer 2007 United Kingdom floods. The water coming into the plant was contaminated and this led to the loss of all running water for approximately 150,000 people in Cheltenham, Gloucester and Tewkesbury.
March 2016 Water Gate Incident
On March 11, 2016 Severn Trent customers in Derbyshire were issued with a 'Do not use' notice due to high levels of chlorine detected in the water supply, leaving thousands of households without a clean reliable water supply.
