Abstract
A filtration apparatus for curb vaults may be installed in existing vaults through the road-level inlet opening into the vault. A support plate assembly of the filtration apparatus suspends a primary and secondary filter and is movable between extended and retracted positions. An adjustable attachment system allows installation of the filtration apparatus by inserting the apparatus through the inlet opening.
Claims20
A filter system for use with an existing in-ground vault having an inlet opening having a height dimension X, a width dimension between opposed edges of the inlet opening Y, and a vault interior having interior walls including a first interior wall nearest said inlet opening and a second interior wall opposite the first interior wall, comprising:
- a plate having a height dimension less than X and a width dimension less than Y;
- plate support means for fixing said support plate in the vault interior, said plate support means comprising a support plate suspension bar attached to an edge of said plate that is adjacent said first wall, said suspension bar having a length dimension greater than Y;
- at least a primary filter suspended from said plate and extending through a filter opening in said plate, said primary filter installable through said filter opening after said support plate is fixed to said vault interior.
A method of installing a filter system into an existing in-ground vault having an inlet opening having a width Y defined by the distance between opposed inlet opening edges, and a vault interior having opposed first and second vault walls, comprising the steps of:
- a) inserting a filter support plate through said inlet opening;
- b) supporting a leading edge of said support plate on the first of said opposed vault walls;
- c) supporting a trailing edge of said support plate adjacent the second of said opposed vault walls with a suspension bar attached to the trailing edge and located exteriorly of the vault interior, the suspension bar having a length between opposed ends of the suspension bar greater than Y, and wherein the respective ends of the suspension rod overlap the respective inlet opening edges;
- and
- d) fixing said support plate to said vault interior.
