Capenhurst is home to a
uranium enrichmentplant owned by Urenco Group. It has its own railway station, on the Wirral Lineof the Merseyrailnetwork. The local amateur football team play in the Carlsberg West Cheshire League.
In 1999 the journalist Duncan Campbell published claims that a fifty metre high tower on the premises of the uranium enrichment plant had been used to intercept telephone calls transmitted by
microwavebetween the British Telecom towers at Gwaenysgor, Clwyd, and Pale Heights, near Chester. Campbell claimed that the interception was conducted by the Government Communications Headquarters, GCHQ, initially from a temporary installation on the roof of the plant until commissioning of the tower in 1990.
The main route for phone calls between the
Republic of Irelandand the United Kingdomwas via the submarine fibre optic cable UK-Ireland 1, landed at Holyhead, Anglesey, then transmitted by a microwavelink. Campbell claimed that calls were monitored by GCHQ until 1998 when the Irish telecomunication system was changed.
