Abstract
Abstract This invention includes a series of longitudinally aligned double-tee sections, each of which includes an upper horizontal section at ground level for accommodating pedestrian traffic, and spaced vertical supporting legs pending from the horizontal section below ground level. There is a void between the support legs forming a dry well for receiving runoff water. The support legs are perforate for releasing collected water into an adjacent stone or gravel bed for absorption purposes. A catch basin located either inside or outside the double-tee section receives the runoff water and feeds it to the dry well, the catch basin collecting and retaining debris and sediment for ready removal.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
194 words
A combination storm water retention assembly and sidewalk for positioning in a ground trench, including: a. water-absorbent material at the bottom and sides of the trench, b. a plurality of units in aligned, longitudinal relationship in the ground trench, c. each of said units including an upper, flat section at ground level serving as a walking surface, d. a plurality of support members pending from said upper flat section into the trench, e. said support members being perforated to permit passage of water therethrough into the water absorbent material at the sides of the ground trench, f. said support members being in substantially parallel spaced relationship and extending longitudinally of the unit, g. whereby a channel is formed between said support members, said upper flat section and the bottom of the trench, h. catch means adjacent said unit for receiving surface runoff water, and i. means for feeding said water from said catch means into the channel, j. whereby surface water is retained within the assembly and permitted to percolate through said absorbent material into the bottom of the trench and through the perforations of said support members at the sides of the trench.
Claim 2
Dependent Claim
194 words
A combination storm water retention assembly and sidewalk for positioning in a ground trench, including: a. water-absorbent material at the bottom and sides of the trench, b. a plurality of units in aligned, longitudinal relationship in the ground trench, c. each of said units including an upper, flat section at ground level serving as a walking surface, d. a plurality of support members pending from said upper flat section into the trench, e. said support members being perforated to permit passage of water therethrough into the water absorbent material at the sides of the ground trench, f. said support members being in substantially parallel spaced relationship and extending longitudinally of the unit, g. whereby a channel is formed between said support members, said upper flat section and the bottom of the trench, h. catch means adjacent said unit for receiving surface runoff water, and i. means for feeding said water from said catch means into the channel, j. whereby surface water is retained within the assembly and permitted to percolate through said absorbent material into the bottom of the trench and through the perforations of said support members at the sides of the trench.
Claim 3
Dependent Claim
21 words
The combination water retention assembly and sidewalk of claim 1, wherein: a. each of said units is of precast double-tee construction.
Claim 4
Dependent Claim
50 words
The combination storm water retention assembly and sidewalk of claim 1, wherein: a. said catch means comprises a drain and catch basin for receiving the runoff water located adjacent one of said units, and b. said means includes a pipe connecting said catch basin to the channel of said unit.
Claim 5
Dependent Claim
85 words
The combination storm water retention assembly and sidewalk of claim 1 wherein: a. said catch means comprises a catch basin positioned in the channel between said supporting members, b. openings in the wall of said catch basin to permit water to flow from said catch basin into the channel, and c. said catch means includes a drain at ground level for receiving runoff water, and d. a pipe extending from said drain to said catch basin for feeding the runoff water to said catch basin.
Claim 6
Dependent Claim
53 words
The combination storm water retention assembly and sidewalk of claim 1, wherein: a. said catch means includes a cylindrical vessel, b. a water inlet in said cylindrical vessel, c. a water outlet in the upper extremity of said cylindrical vessel, and d. a drain connected to the water inlet of said cylindrical vessel.
Claim 7
Dependent Claim
39 words
The combination storm water retention assembly and sidewalk of claim 1, with the addition of a. a manhole cover in said horizontal upper section superjacent said cylindrical vessel, for effecting removal of debris and sediment collected in said vessel.
Claim 8
Dependent Claim
97 words
The combination storm water retention assembly and sidewalk of claim 1, with the addition of a. a baffle placed in said channel in engagement with the bottom of the ground trench, b. said baffle including an imperforate body, the sides of which are in contiguous engagement with said support members, and the upper portion thereof being in spaced relation to the upper extremity of the channel, c. whereby when said assembly is located on a sloping terrain, water will be held in a stepped formation to prevent collection thereof in one spot and assure proper soil absorption.
Claim 9
Dependent Claim
63 words
The combination water retention assembly and sidewalk of claim 1, with the addition of: a. an end closure for said assembly at the end of the ground trench, b. said end closure including a rectangular member for positioning in the ground trench, c. said rectangular member being perforate to permit passage of water in the channeL therethrough for percolation into the surrounding ground.
