Could work in a situation where the water supply is well above the consumers, and there's too much pressure, but otherwise, if the gen robs too much energy from the flow then it will need supplementary pumping to increase pressure to an acceptable level... which defeats the purpose.
I remember one of the potential Y2K consequences was that running water could be affected, because delivering it typically uses electric pumps.
