A woman says a noisy Thames Water generator located just yards from her back door is ruining her life.
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.
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.
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".
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".
