Abstract
An apparatus providing low volume irrigation from a previously installed sprinkler irrigation system including one or more sprinkler heads connected to a water supply conduit. The apparatus includes a manifold (50) having a water distribution passage (34) therein. The water distribution passage (34) includes an inlet end (35) and an outlet end (36) with the outlet end adapted to receive a conveyance channel (38) for distributing water to an emission point (42, 43). A flow control device (39) is associated with the water distribution passage (34) to control the flow rate of water through the passage to a rate exceeding a local hydraulic loading rate of the soil in the area around the emission point (42, 43). The manifold (50) is connected to receive water which is supplied to the sprinkler head through the water supply conduit. The manifold (50) may be connected to the sprinkler head body (22) or to the conduit (28) below the sprinkler head body and may replace the sprinkler type irrigation completely or supply irrigation supplemental to the sprinkler type irrigation.
