Methods and systems for a subsurface upflow wetland for wastewater treatment that includes a series of parallel treatment cells, each cell including from bottom to top, a layer of gravel, a layer of sand over the gravel to remove pathogens from a septic effluent, a pollution control medium above the sand later to remove nurtients, total suspended solid, and biochemical oxygen demand and a growth media mixture layered on top of the pollution control pmedia to grow plants, and a gravity distrubition system to distribute effluent to the series of parallel treatment cells. The pollution control medium inlcudes at least one recycled material and at least one naturally occuring material. In an embodiment in includes recycled tire crumb, sand, and limestone or recycled tire crumb, compost, sand and limestone.
