Abstract: A gas vent for a landfill includes a sub-surface gas collection manifold for collecting sub-surface gas from beneath a geomembrane. Preferably, the collection manifold includes a plenum for receiving sub-surface gas. A conduit is connected to and extends upwardly from the plenum, with the conduit communicating with the interior volume of the plenum and having an upper discharge end. The conduit is adapted and provided for communicating sub-surface gas from within the interior volume of the plenum through the geomembrane. An activated charcoal filter disposed adjacent the discharge outlet of the hood removes odors from the gas as it is discharged from the discharge outlet.

Abstract: A low-profile fluid collection conduit includes an elongate outer cover having an upper portion and a lower portion generally opposite the upper portion, with the outer cover being much wider than it is tall and defining an interior volume. An elongate rigid spacer is fitted within the interior volume of the elongate outer cover, with the elongate spacer allowing the majority of the interior volume to be unfilled so as to permit the flow of fluid along and within the elongate outer cover. The collection conduit is used with a fluid-impermeable membrane as part of a landfill fluid collection and conveyance system.
