Severn Trent

The Severn Trent Water Authority was established in 1974. In July 1989, the Severn Trent Water Authority was partially privatised under the Water Act 1989, together with the rest of the water supply and sewage disposal industry in England and Wales, to form Severn Trent Water, with a responsibility to supply freshwater and treat sewage for around 8 million people living in the Midlands of England and also a small area of Wales.In May 1991, it went on to acquire Biffa, a waste management business. In October 2006, Biffa was de merged from the group Severn Trent, and was subsequently listed separately on the London Stock Exchange. In January 2007, the American side of Severn Trent Laboratories was sold to HIG Capital.In 1993 the company acquired East Worcester Water plc, a former statutory water company whose area was surrounded by Severn Trent's existing water supply area, and the operations were merged.In September 2007, the company announced they would be closing its headquarters in Birmingham and relocating to a custom built office complex in the centre of Coventry in the autumn of 2010.In June 2016, Severn Trent Water and United Utilities formed Water Plus in preparation for the water market deregulation, to provide the retail services for their non household customers, after being granted approval by the Competition & Markets Authority.In 2017 Severn Trent plc acquired Dee Valley Water, a water-only company with an area adjoining Severn Trent Water's own. In 2018 the areas of the two operating companies were adjusted so that Hafren Dyfrdwy took on all Severn Trent Water's water supply and wastewater operations in Wales, and the small area of the former Dee Valley operation within England became part of Severn Trent Water.
