Is it possible to change the sentence below to the active voice? I have tried but can't seem to do it. Have been left is the present perfect in the passive form (I think!) and that is what I've been trying to change to the active voice.
Thousands of households have been left without water after the nearby water treatment plant was shut down due to the extreme turbidity in the river supplying water to it.
Can it be done?
Thank you for your help.
