Unfortunately, that won't work. You'd still need the powered pumps to draw the water out of the 'uphill' end of the capillaries, and that would cost more energy then simply pumping the water up.
And another problem is contamination. Once the 'pump' gets contaminated with organic material, it decreases it surface energy and the ability to move the water upwards.
