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. A low-pressure relief valve is operative for opening when positive pressure exists within the conduit. The low-pressure relief valve comprises a valve membrane normally resting upon a seat and which is lifted off the seat by low positive pressure.
