A system for installing and labeling lay flat irrigation pipe in flooded rice and furrow irrigated fields, and a trailer for laying a roll of pipe in an irrigated field. The trailer includes a flexible hitch assembly positioned at a first end of the trailer, wherein the hitch assembly couples the trailer to a vehicle. The trailer also includes a distribution assembly positioned at a second end of the trailer, wherein the distribution assembly includes a spindle and wherein the distribution assembly couples the roll of pipe to the trailer; and a gooseneck frame including a first end coupled to the hitch assembly and a second end coupled to the distribution assembly, with an upper member between the first end and the second end of the gooseneck, wherein the upper member of the gooseneck is elevated relative to the hitch assembly. The trailer may also include offset tandem wheels with a furrow assembly to facilitate the creation of a furrow ditch and for traversing flood irrigated levees for the purposes of installing lay-flat polyethylene pipe for irrigation. The trailer may also include an adjustable telescoping hitch to adjust to various vehicle hitch heights. The system includes a labeling system for indicating the punch size needed along the pipeline during installation. A computerized hole selection plan is developed and transferred to a microprocessor device, where sensors or a global positioning system is co-locate the device so the punch label can be applied along the pipe during installation.

A gravity irrigation system includes a distribution piping having apertures to distribute water to a field, and a valve located upstream of the distribution piping. The valve is configured to limit a pressure of the water being delivered to the distribution piping. The system also includes a sump configured to receive the water at a lowest elevation of the field, a depth sensor disposed within the sump, and a return pump disposed at least partially within the sump and configured to move the water to an elevated portion of the field. The system also includes a motor configured to drive the return pump, and a power source coupled to a variable frequency drive. The variable frequency drive is configured to power the motor and control a motor speed proportionately to an indication of the depth sensor. The system also includes a transfer piping coupled to an outlet of the return pump to bring the water from the return pump to a check valve and from there to the distribution piping at a low pressure side of the valve.

A flexible seal system for provision of a substantially watertight seal between adjacent concrete panels; said system comprising a first flexible seal member proximate a first end of one said concrete panel; said first flexible seal member including a surface component extending over a portion of an outer surface of said concrete panel; said surface component extending from at least one anchor component projecting from said surface component and embedded within said concrete panel; said first flexible seal member further including an overlap component extending from said surface component beyond said first end of said concrete panel; and
a second flexible seal member proximate a second opposite end of an abutting said concrete panel; said second flexible seal member including a surface component extending over a portion of a surface of said abutting concrete panel; said surface component of said second flexible seal member extending from at least one anchor component projecting from said surface component and embedded within said abutting concrete panel; and
wherein the overlap component of the first flexible seal member is structured and selected in use to overlap the surface component of the second flexible seal member sufficient to permit welding of at least a portion of said overlap component of said first flexible seal member to at least a portion of said surface component of said second flexible seal member so as to form a continuous welded seal between and along the length of said first flexible seal member and said second flexible seal member.

A plastic leaching unit for receiving water when buried in trenches in soil comprises a plurality of pillars interconnected by struts. A canopy made of sheet material is attached to the tops of the pillars. The pillars are arranged as spaced apart integral assemblies to enable lateral and vertical bending of the leaching unit, for conforming to a not-straight trench. Preferably, the canopy comprises a second perforated sheet overlying a first sheet having larger perforations, the combination arranged for flow of water and gases while hindering soil particulates. Preferably, the canopy extends a greater amount from the first end of each unit than from the second end, to facilitate end-to-end mating of the units. Leaching units may be stacked one upon the other within a trench.

Exemplary embodiments are disclosed of liners, linings, and liquid containment vessels including the same. Also disclosed are exemplary method of providing liners and linings for liquid containment vessels, such as process tanks, immersion tanks, containment pits, gravity feed conduits for transferring or conveying liquid, etc. In an exemplary embodiment, a liner or lining is anchored to at least one structural component by at least one extrusion weld and at least one mechanical fastener. The mechanical fastener is coupled to the structural component. The extrusion weld is coupled to the mechanical fastener. The liner or lining may be anchored to a wide range of structural components, such as a frame, a framework, a frame member, a tank, a wall, a support member, a reinforcing member, an outer shell, a substrate (e.g., concrete, etc.) or sidewalls defining a pit or a gravity feed conduit, combinations thereof, other structures or components, etc.

A method for managing the flow of water beneath a ground surface uses modules. Assemblies of such modules are disclosed. The modules include supports and a deck portion, and the supports are spaced apart and form multiple channels with a main section of the deck portion. The deck portion also includes at least one section extending from a main section.
