    Abstract: A device for removing petroleum based contaminants from the runoff water that passes into a storm drain. The device is a filter apparatus that can be added to a storm drain. The filter apparatus includes a filter cage that defines an open central conduit and a filter cartridge that wraps around the periphery of the filter cage. During normal rain conditions, water enters the sewer grate near the edges of the sewer grate. This water falls through the filter cartridge and is filtered. Solid debris that is mixed with the water is deflected through the central conduit and falls through the filter apparatus. During flood conditions, excess water is allowed to pass through the center conduit of the filter cage unfiltered in order to preserve the water flow capacity of the storm drain.

  • Patent number: 6017166
    Abstract: A catch basin guard and filter for preventing entry into a catch basin and subsequently a storm drain. The preferred embodiment provides a form fitting cover having a grate. The invention is designed for catch basins being installed in construction sites. The invention blocks the inlet of a catch basin, thereby deterring the entry of debris, animals and, most importantly, children. This deterrent increases the completion of construction because the catch basin will need less cleaning and evacuating before coupling to the existing storm drain system. The invention additionally has a mesh filter covering the grate, and a second embodiment employs overflow apertures to provide for the passing of fluids should the filter become clogged.

The cover members are laid above the base members and combine therewith to form an enclosed drainage channel. Each cover member has at least one opening (37) extending through a side wall thereof and communicating with the channel. The lowermost part of the opening intersects the outer surface of the respective wall at a location (36) that is no closer to the bottom than to the top of the cover member. A carriageway (35) can be laid with its surface no lower than the point (36), so that drainage is effected through the opening (37) while the base members (27) lie at a significant depth below the carriageway surface.

  • Patent number: 4192625
    Abstract: A precast concrete catch basin is provided with an integral transverse gutter inlet shaping form across the front. The form is spaced from the top slab of the catch basin and forms therewith a gutter inlet for the passage of water into the catch basin. The transverse form is arcuate in shape and serves as a form and top surface for a concrete gutter inlet cast against it. Anchor bolts are provided in the side walls of the catch basin and extend outwardly through the transverse form into the area of the concrete gutter so as to secure the inlet shaping form to the side walls and to anchor the catch basin to the gutter after the gutter has been cast in the field against the transverse gutter shaping form.

  • Patent number: 3930372
    Abstract: A method and arrangement for preventing an underground manhole assembly from moving upwards in response to a change in soil conditions beneath the assembly are disclosed herein. For example, in the event the soil directly beneath the assembly includes substantial moisture and in the event this moisture freezes, the latter expands against the base of the assembly and in many cases pushes the assembly in an upward direction. The method and arrangement disclosed herein eliminates this upward movement by the utilization of a pressurized fluid barrier which is maintained between the manhole assembly and the soil directly beneath the assembly.
