A trench drain section for connecting to a mating trench drain section and forming a trench drain system. The trench drain section includes a trough having sidewalls connected by a bottom wall and cooperating to define a channel. The trough further includes an open top, an open end and is connectable to another trench drain section. A pair of rails extend along the sidewalls and are secured by fasteners. Extending over the open top, a grate is supported on the rails. The drain section also includes an alignment bracket having first and second portions that are individually connectable with one of the fasteners. When one of first and second portions is connected with one of the fasteners, the other the portions of the alignment bracket extends from the trough through the open end thereof and is available for connecting to another trench drain section.

A road gutter having a dust collection function, consisting of a gutter groove (11) and a cover stopper (10) that covers the gutter groove (11). The side surface of the cover stopper (10) is “T”-shaped. Plugs (10b) of the cover stopper (10) are embedded in the gutter groove (11), and a shoulder (10c) of the cover stopper (10) is supported on platforms (11c) formed by the left and right walls of the gutter groove (11) to bear the weight of the whole cover stopper (10). The front surface of the cover stopper (10) is inverted “U”-shaped, and forms a dust absorption channel (10a) with a solid part of the gutter groove (11). The dust absorption channel (10a) communicates the gutter groove (11) with an external space. Road dust and mess enter the gutter groove (11) from the external space by means of the dust absorption channel (10a) under the drive of an external force, and fall to the bottom of the gutter groove (11).

A valve rod isolation apparatus for reducing valve rod exposure to moisture and debris in a subsurface environment, wherein the valve rod is housed within an isolation sleeve that is sealed top and bottom.

A channel drain for use in a fabricated surface having an exposed appearance. The channel drain includes a first body having a plurality of support surfaces, with each support surface extending from a respective body sidewall in spaced relation to a body lower wall. A plurality of inserts are insertable into the first body. Each insert includes an insert cavity sized and structured to receive a selected material having an appearance substantially identical to the exposed appearance of the fabricated surface. Each insert is supported by certain ones of the plurality of support surfaces when inserted into the first body and is sized and structured to define a gap between the pair of body sidewalls when inserted into the first body, with the gap allowing for fluid to flow therethrough toward the body lower wall.

A method, a system and an apparatus for wastewater treatment using a combination of separation of fat, oil and grease (FOG) and biological treatment for reducing the amount of fat, oil and grease (FOG) in wastewater with the aid of a liquid culture of microorganisms is provided. In particular, the technology disclosed relates to a method and process for the separation and treatment of FOG, as well as a container tank and an outlet pipe construction adapted for improving the gravimetric FOG separation process and the breaking down of FOG using microorganisms.

A perforated subirrigation and drainage pipe includes a pipe body and a permeation irrigation inner pipe. The permeation irrigation inner pipe is integrally formed with the pipe body and disposed at a top of an interior of the pipe body along a longitudinal direction thereof; multiple irrigation perforations, distributed along a longitudinal direction of the permeation irrigation inner pipe, are provided on a pipe wall of a bottom thereof; and an opening is provided on a pipe wall of a bottom of the pipe body; two flow guide baffles are respectively located at two sides of the opening and on an inner wall of the pipe body; a first irrigation and drainage channel is formed between each flow guide baffle and an outer wall of the permeation irrigation inner pipe, between each flow guide baffle and the inner wall of the pipe body, and between the two flow guide baffles.
