Q. (See question 2041 above on water that was used to perform work). Why is water that "worked" by turning a water motor, different from any common water whose volume was measured by a water meter. After all the water "worked" by making the meter register the volume that went by, and therefore no measured water anywhere should be kasher even for netilat yadaim?
A. Horav Shlomo Miller's Shlit'a opinion is that since actually one is not interested in the water meter working as he is being charged for the water used, that unwanted performance is not considered work.
(Besides, one can hardly say that the water will be discarded because of this work).
