7 Stormwater Barrel Treatment Train Heavy Metals (Zn, Cu, Al, Fe) Nutrients (COD, BOD) PROCEDURE Place barrels on de-escalating platforms (e.g. 3 concrete blocks) to maintain gravity flow configuration. Extend external plumbing as necessary to reach subsequent treatment barrels. Removes bulk solids prior to filtering suspended solids and actively adsorbing heavy metals and nutrients $0 (to connect previously built Vortex Clarifier, Filter Barrel, and Media Barrel) Vortex Clarifier Filter Barrel Skim drain Pea Gravel Splash Dampener Media Barrel Pool Filter Sand Splash Dampener Active Media Pea Gravel Drain Rock Pea Gravel Drain Rock

8 Stormwater Hybrid Treatment Train Heavy Metals (Zn, Cu, Al, Fe) Nutrients (COD, BOD) PROCEDURE On a level surface, the system will maintain gravity flow configuration. Extend external plumbing as necessary to reach the media barrel or drain site drain. Removes bulk solids prior to filtering suspended solids and actively adsorbing heavy metals and nutrients. Higher capacity solids filtration, with segregated active media for easier replacement or recharge. $0 (to connect previously built Filter Box and Media Barrel) Media Barrel Filter Box Splash Dampener Splash Dampener Active Media IBC Drain
