Water is already priced based on the type and quantity of usage. The more you use, the more it costs. You can raise prices for farms without "screw[ing] all the poor and middle class." If you raise farm water prices, you will find that water-intensive crops will be less profitable (even with raised prices) and farms will switch to crops which use less water. Rationing may have the same effect, or it may instead have the effect of fewer crops being produced and prices going up.
