The water treatment cartridge of claim 5, wherein the extension is threaded and engaged with an O-ring. 7. The water treatment cartridge of claim 1, wherein the water treatment medium is sized and spaced within the interior volume to form a gap between an interior volume facing surface of the sidewall and the water treatment medium and a first end facing surface is engaged with a top cover that directs water radially outward toward the sidewall of the water treatment cartridge; thereafter the water is directed radially inward and through the water treatment medium and into a hollow central conduit that delivers a treated water flow to an outlet. 8. The water treatment cartridge of claim 1, wherein the first and second locking configurations arrange the water treatment cartridge at a specific stage of a customizable multi-stage water treatment system. 9. The water treatment cartridge of claim 1, wherein the water treatment cartridge is cylindrically shaped and the water channel flow path segment has an arch-shaped cross-section. 10. The water treatment cartridge of claim 1, wherein the water treatment medium is chosen from the group consisting of: activated carbon particles, a carbon powder, a vitamin treatment material, aluminosilicate material, an organic acid, inorganic acid, particles sintered with a plastic binder, carbon particles coated with a silver material, a block of porous carbon, an ion exchange material, resin beads, flat filtration membranes, fibrous filtration structures, zeolite particles, zeolite coatings, alumina, diatomaceous earth, polyethylene, charged-modified webs, melt-blown webs, and microfiber glass. 11. The water treatment cartridge of claim 1, wherein the first locking configuration disposed on an exterior facing surface of the first end comprises at least one keyed mating arrangement and a second locking configuration disposed on an exterior facing surface of the second end comprises at least one keyed mating arrangement such that the first end is configured to directly engage a corresponding first locking configuration and the second end is configured to directly engage a corresponding second locking configuration that is different than the first locking configuration. 12. The water treatment cartridge of claim 11, wherein the at least one keyed mating arrangement on the exterior facing surface of the first end is at least one protrusion having a neck portion that extends from the water treatment cartridge and a head portion on the neck portion, wherein the head portion is larger in diameter than the neck portion and wherein the second locking configuration is at least one recess on the exterior facing surface of the second end. 13. The water treatment cartridge of claim 1, wherein the water channel flow path segment is proximate the exterior facing surface of the water treatment cartridge. 14. The water treatment cartridge of claim 5, wherein the water channel flow path segment is proximate the exterior facing surface of the water treatment cartridge. 15. A water treatment cartridge, which is a segment of an overall filter comprised of a plurality of segments, wherein the water treatment cartridge comprises: an untreated water receiving end that receives untreated water into an interior volume of the water treatment cartridge wherein the untreated water receiving end is opposite a treated water delivering end that delivers water treated by a water treatment medium within the interior volume;a sidewall extending between the untreated water receiving end and the treated water delivery end, enclosing the interior volume defined by a treatment medium facing interior wall; a water channel flow path segment formed within the sidewall that extends within the sidewall and between the untreated water receiving end and the treated water delivery end; anda treated water outlet extension protruding from the untreated water receiving end or the treated water delivery end of the water treatment cartridge wherein the extension permits a flow of water to travel between the treatment medium spaced within the water treatment cartridge in an opposite direction than untreated water flows through the water channel flow path segment. 16.
