Abstract: Certain aspects of the present invention are directed to an assembly comprising a series of rods for collecting water or transporting water which is structured to result in capillary spaces between it and other similar-shaped rods when such rods are adjacent to another. Each rod has a cross-sectional shape with one surface portion of the rod being a greater distance from the center of the rod than another surface portion of the rod. The rods are configured to be laid together in parallel in an assembly or prefabricated into an assembly to create a network of channels for the collection and transport of water by capillary action that is free from soil and debris, wherein the rods are partially in contact to create non-uniform hallow spaces.

Abstract: A rod for collecting water or transporting water structured to result in capillary spaces between it and other similar-shaped rods when such rods are adjacent to one another. The rod has a cross-sectional shape with one surface portion of the rod being a greater distance from the center of the rod than another surface portion of the rod. The rods can be laid together in an assembly or prefabricated into an assembly that provides an efficient, high capacity water collection and/or transportation system that is resistant to clogging.

Abstract: Embodiments described herein are related to water management units for extracting water from moist soil. The units extract water and collect it to be siphoned away as waste water or for later use. A water management unit comprising: an elongate collection portion; and an extraction portion arranged to discharge extracted water into the collection portion, wherein the extraction portion comprises at least one rib extending laterally from the collection portion along a length of the collection portion. Water is collected by capillary action.
