Patent number: 10926199Abstract: Vertically oriented cylindrical vaults, boxes, systems, and methods of treatment systems to capture pollutants from storm water runoff and prevent the conveyance of these pollutants from entering a receiving water body or landscape area, which is designed to be a part of a local permanent storm water drainage infrastructure. A flow deflector can include a flow spreader for splitting an incoming flow into two flow paths that interact with high profile vertical baffle(s), and with low profile vertical baffles, and angled low profile vertical baffles that extend above downwardly inclined surfaces of a horizontal deflector having an opening for allowing debris to fall. Treated water can pass out of an outflow pipe on an opposite side of the cylindrical vault. A bottom open skimmer or a flow restrictive skimmer or a hydro-variant skimmer can be used in front of the output flow port.Type: GrantFiled: December 6, 2018Date of Patent: February 23, 2021Assignee: Oldcastle Infrastructure, Inc.Inventor: Tom Happel

Patent number: 10384956Abstract: Vaults, boxes, chambers, systems, and methods of treatment systems to capture pollutants from storm water runoff and prevent the conveyance of these pollutants from entering a receiving water body or landscape area, which is designed to be a part of a local permanent storm water drainage infrastructure. The system enhances the removal efficiency of almost any type of filtration media by increasing contact time between storm water runoff and the media, and also offers an easy and inexpensive method for serving the media, without having to remove or replace the media. A media filter can include a bottom screen, a media layer, and at least one top lid that can be opened to allow for backwashing of the media layer without removing the media layer from the filter. A servicing system can include pivotal spray heads to pivot to parallel positions over a sloped floor to flush debris toward easy to reach locations to be vacuumed, and vertical spray heads which can break up debris bridges.Type: GrantFiled: July 25, 2017Date of Patent: August 20, 2019Assignee: Oldcastle Infrastructure, Inc.Inventor: Tom Happel
