Improved golf course drainage systems (10) are provided which include respective drainage subsystems (12, 16), beneath the greens(14) and fairways (18) of a golf course, together with degassing apparatus (36, 64, 84) operably coupling the subsystems (12, 16) and permitting venting of contaminating gases generated within the drainage systems (10). The degassing apparatus (36, 64, 84) includes a tubular connector (44, 66, 85) establishing an offset distance between the adjacent ends (40, 42) of the subsystems (12, 16), along with a vent (46, 68) in communication with the connector (44, 66, 85). The connector (44) maybe upright to establish a vertical offset distance, or a generally horizontal connector (66, 85) may be used to establish a lateral or axial offset distance. The apparatus (36, 64, 84) permits normal drainage of water while preventing build up of undesirable gases which would otherwise rise through the soil and adversely affect the turf of the golf course.
