A storm water filter system for filtering storm water being fed into an in-ground well includes a housing having an inlet and an outlet, with the outlet being connected to an in-ground recharge well. A plurality of open chambers are formed in the housing. An inlet filter box has an open end located in the housing and positioned with the open end facing the housing inlet. An outlet screen filter is positioned over the outlet for capturing debris from water entering the outlet and has a bypass for water to pass when the filter becomes partially blocked.
An upflow stormwater filter has horizontally aligned filter media to provide a high throughput for treatment of contaminated water, longer life to filter media, and without material head drop.
The present invention relates to an apparatus and method, using the apparatus, for blocking the passage of solid materials into or through a channel while permitting the passage of fluid; automatically releasing the blocked solid materials under predetermined conditions when priority is given to maximizing the passage of fluid; automatically re-closing after the accumulated solid materials have passed downstream, and resuming the blocking of solid materials; and, repeating the process upon recurrence of the predetermined conditions.Although the invention relates to street storm-water drainage channels, particularly inlets to catch basins, it can be applied to any fluid-flow channel where blocking the passage of solid materials is important but where there are conditions under which priority should be shifted from blocking the solid materials to releasing them downstream.
The present invention relates to an apparatus for maximizing the blockage of fluid borne solid materials from passage through a catch basin into the downstream parts of a fluid flow channel, with minimum impact on the volume and rate of fluid passing through the channel. The apparatus comprises at least one filter sheet secured within the catch basin at a location above and covering a large proportion of the floor of the catch basin, an overflow wall separating the filter area from an unfiltered overflow area, and a diverter for directing incoming trash away from the overflow area and to the filter side of the overflow wall. Although the apparatus covers a large area within the catch basin, the overflow wall, overflow area, and clearance between the filter sheet(s) and the floor provide sufficient space for fluid and excess trash to pass in the event the capacity of the apparatus for holding them is exceeded. Preferably, the apparatus also has a drain-access hole through the filter sheet(s) and a movable hole cover located appropriately to facilitate access to the catch basin drain.
