Storm Water Pretreatment Chamber

BACKGROUND OF THE INVENTION

When it rains on unimproved natural land, the rain and storm water runoff is either absorbed into the soil or moves along the surface of the land, moving downward towards creeks and rivers. However, as areas become more densely populated, this natural dispersion of rain and storm water is altered by the man-made improvements, for example, parking lots, roads, and buildings. This leaves less open ground surface to absorb the rain and adds to the storm water runoff.

In many cities, storm water sewers are constructed to handle the large amount of storm water runoff that comes off of the buildings, parking lots, and roads. The storm water sewers route the water to creeks and drainage ditches, which form the tributaries to larger rivers.

Common ways of treating storm water involve installing a curb-cut on a side of a street and allowing the storm water to flow out into a rain garden. However, debris can build up and cause the storm water to by-pass the curb cut before the rain garden is full of storm water. In addition, accumulated sediment in the rain garden can smother the existing plants, reduce infiltration and/or filtration capacity, and is unsightly.

Inlet materials and structures at the curb-cut inlets are variable. For example, turf strips and rock inlets are commonly used. Turf strips are often ineffective and require exhaustive raking and annual replacement. Rock inlets also lose their effectiveness rapidly without frequent labor intensive cleaning. Alternative structures, for example, chambers filled with porous media and underdrains, can be cost prohibitive and may fail resulting in flooding the rain garden with debris, which requires extensive clean-up.

What is desired is an easily maintained device that can remove debris and sediment from storm water and allow the treated storm water to enter a storm water receiving feature, for example, a rain garden.

FIG. 3 is a perspective front view drawing illustrating an exemplary storm water pretreatment chamber 300 without a cover. The storm water pretreatment chamber 300 included a base 301, a cover (not shown), an inlet sidewall 302, an inlet grate 303, a first sidewall 304, a second sidewall 305, a filter sidewall 306, a filter 307, an outlet grate 308, a first lifting cable 309. and a second lifting cable (not shown). The base 301 has a first surface, a second surface, a proximal end, and a distal end. The base 301 includes an inlet sidewall 302, a first sidewall 304, a second sidewall 305, and a filter sidewall 306. The inlet sidewall 302 has a first surface, a second surface, a proximal end, a distal end, a first edge, a second edge, a third edge, a fourth edge, and an inlet grate 303. The first edge of the inlet sidewall 302 is in contact with the second surface of the base 301. The first surface of the inlet sidewall 302 is in communication with an atmosphere and in position to receive untreated storm water and to collect one or more floating debris that does not pass through the inlet grate 303. The first sidewall 304 has a first surface, a second surface, a proximal end, a distal end, a first edge, a second edge, a third edge, and a fourth edge.

In the claims provided herein, the steps specified to be taken in a claimed method or process may be carried out in any order without departing from the principles of the invention, except when a temporal or operational sequence is explicitly defined by claim language. Recitation in a claim to the effect that first a step is performed then several other steps are performed shall be taken to mean that the first step is performed before any of the other steps, but the other steps may be performed in any sequence unless a sequence is further specified within the other steps. For example, claim elements that recite “first A, then B, C, and D, and lastly E” shall be construed to mean step A must be first, step E must be last, but steps B, C, and D may be carried out in any sequence between steps A and E and the process of that sequence will still fall within the four corners of the claim.

Furthermore, in the claims provided herein, specified steps may be carried out concurrently unless explicit claim language requires that they be carried out separately or as parts of different processing operations. For example, a claimed step of doing X and a claimed step of doing Y may be conducted simultaneously within a single operation, and the resulting process will be covered by the claim. Thus, a step of doing X, a step of doing Y. and a step of doing Z may be conducted simultaneously within a single process step, or in two separate process steps, or in three separate process steps, and that process will still fall within the four corners of a claim that recites those three steps.

Similarly, except as explicitly required by claim language, a single substance or component may meet more than a single functional requirement, provided that the single substance or component fulfills the more than one functional requirement as specified by claim language.
