A woman says a noisy Thames Water generator located just yards from her back door is ruining her life.br br Fed up Rachel Freeston, 55, claims she has to endure a "constant" racket and fumes from the machine at the bottom of her garden in Lambourn, Berkshire.br br She says the pollution means she "may as well smoke 50 cigarettes a day" - while the "droning" sounds mean she only gets a few hours sleep each night. br br Thames Water claim that the "filter unit" is "vital" for protecting the river Lambourn from untreated sewage - but say they are looking at "what more can be done to minimise the impact on neighbours".br br But Mrs Freeston, who lives with her husband Stephen, 60, and their 14-year-old son, is desperate for it to be moved - saying it has become "unbearable".
