A method and system for harnessing an unsaturated flow of fluid utilizing a reversible unsaturated siphon conductor of fluid having a tubarc porous microstructure. Fluid is conducted from a zone of higher (+) fluid matric potential to a zone of lower (−) fluid matric potential utilizing a tubarc porous microstructure. The fluid can be reversibly transported from different zones bearing a differential fluid matric potential according to the status of the fluid matric potential in each zone utilizing the tubarc porous microstructure. The tubarc porous microstructure comprises an enhanced geometric porosity. In this manner, the fluid can be harnessed for irrigation, drainage, filtration, fluid recharging and other fluid delivery uses, such as refilling writing and printing instruments.
