A subsurface irrigation system (10) includes one or more water distributing branches (16) comprising a water emitting conduit (20) and a water deflector member (22). The water emitting conduit (20) extends through the area (A) to be watered buried at an emitting depth below the surface of the area and is capable of receiving water at one end and emitting the water at a low overall flow rate along its length. The deflector member (22) extends the entire length of the water emitting conduit (20) generally below the level of the conduit and defines a deflecting area. The water deflector (22) member comprises a layer of substantially water impermeable material and its position generally below the water emitting conduit (20) allows it to block the downward flow of water in the water deflecting area. Deflecting the water below the water emitting conduit (20) forces the emitted water laterally with respect to the conduit and capillary action in the soil draws the deflected water further laterally to saturate a significant area only to the depth of the root zone. The lateral coverage is sufficient to efficiently position several parallel water distributing branches to irrigate a large area such as a lawn area.
