Patent ID: 7837869

Claim:
A storm sewer insert, comprising: a mounting assembly that is constructed and arranged to be mounted to a storm sewer system, wherein said mounting assembly comprises a mounting flange having a annular rim; a filter bag that is fabricated from a mesh material, said filter bag having an upper end; a downwardly depending shroud connected to said mounting assembly and having a lower end that extends within said filter bag; a plurality of suspension elements for suspending the filter bag from the mounting assembly; and at least one covered bypass path for permitting an excess flow of storm water to bypass the filter bag in conditions of unusually high flow when the volume of storm water entering said storm sewer insert exceeds a throughput capacity of said filter bag, said covered bypass path being defined in part by said upper end of said filter bag and said lower end of said downwardly depending shroud, whereby the excess flow of storm water is forced into an upper portion of the filter bag before it escapes through the bypass path so that floatable material can be retained within the filter bag.
