Filtration apparatus for use with drainage structures and method for installing the same

A filtration apparatus for drainage structures, comprising:

• a first grate comprising:
• a proximal support member,
• a distal support member, and
• a filtration assembly, wherein the filtration assembly is secured to the proximal support member and to the distal support member, and wherein the filtration assembly defines a plurality of openings;
• a second grate comprising,
• a proximal support member,
• a distal support member, and
• a filtration assembly, wherein the filtration assembly is secured to the proximal support member and to the distal support member, and wherein the filtration assembly defines a plurality of openings;
• a connecting member configured to removably secure the distal support member of the second grate to the distal support member of the first grate;
• a first anchoring member configured to secure the proximal support member of the first grate to a first wall of a drainage structure;
• and
• a second anchoring member configured to secure the proximal support member of the second grate to a second wall of the drainage structure, wherein the apparatus has a first width extending from the proximal side to the distal side of the first grate and a second width extending from the proximal side to the distal side of the second grate, the combined width of the first width and the second width being greater than the width of the drainage structure.

A method for installing a filtration apparatus for use with drainage structures, said method comprising the steps of:

• providing an apparatus for drainage structures, said apparatus comprising:
• a first grate having a proximal side and a distal side;
• a second grate having a proximal side and a distal side;
• and
• a connecting member configured to removably secure the distal side of the first grate to the distal side of the second grate,
• wherein the first grate and the second grate each have a plurality of openings therein;
• a first anchoring member configured to secure the proximal side of the first grate to a first wall of a drainage structure;
• and
• a second anchoring member configured to secure the proximal side of the second grate to a second wall of the drainage structure, wherein the apparatus has a first width extending from the proximal side to the distal side of the first grate and a second width extending from the proximal side to the distal side of the second grate, the combined width of the first width and the second width being greater than the width of the drainage structure;
• securing the first anchoring member to the first wall of the drainage structure;
• securing the second anchoring member to the second wall of the drainage structure;
• securing the proximal side of the first grate to the first wall of the drainage structure via the first anchoring member;
• securing the proximal side of the second grate to the second wall of the drainage structure via the second anchoring member;
• and
• securing the distal side of the first grate to the distal side of the second grate via the connecting member.
