An improved drip irrigation emitter is provided for low volume supply of water at a trickle or drip flow rate. The emitter comprises a housing adapted for connection to a water supply hose, and includes a water inlet and a water outlet with an elongated pressure reducing flow channel extending therebetween. The flow channel is lined on opposite sides by a plurality of flow diverting ribs which project laterally and partially into the flow channel in a staggered or alternating pattern, in combination with a plurality of flow diverting weirs which project upwardly and partially into the flow channel from a floor thereof. The flow diverting ribs and weirs define a three dimensional tortuous flow path for repeated back-and-forth and up-and-down directional flow change as water travels therethrough, resulting in an improved pressure drop between the water inlet and outlet.
