      To utilize power that is otherwise wasted? The water can still be used in the garden etc. Also if there is a power cut the water often keeps running, so you could use this to charge a small battery or a phone.

        If the power goes out you’d probably be better off using solar or a even gas. Maybe if you’re using water for something else anyways it makes sense but how much power can really be generated by turning a house on for a min? How much water is wasted?
