Abstract: A modular porous swale. The modular porous swale may comprise a porous concrete block and filtration joint. The porous concrete block may snugly fit within a trench having a lower portion filled with an absorption media. The absorption media may include gravel, activated alumina, bone char, or an activated alumina and bone char mixture. The porous concrete block may have a top surface inwardly-sloped to a nadir. The filtration joint may be disposed within the porous concrete block and along the nadir. The liner may cover one or more sides of the porous concrete block. The perforated pipe may be located within the absorption media. The filtration joint may substantially align above a portion of the perforated pipe when the modular porous swale is installed within the trench.

Abstract: A modular porous swale filtration system. The modular porous swale filtration system may comprise one or more modular porous swales, absorption media, liner, and perforated pipe.
