Abstract
A filtration apparatus for use with drainage structures and a method for installing the same are provided. The filtration apparatus has a first grate and a second grate, which, when installed and secured together, establish a filtration barrier between the inlet and bottom of a drainage structure for filtering stormwater runoff entering the drainage structure. The first grate and second grate are secured to internal walls of the drainage structure via anchoring members. The anchoring members allow each of the grates to rotate to facilitate transition of each grate from a hanging to a suspended position. A connecting member secures the first grate and the second grate together so that the grates bisect the cavity of the drainage structure.
