An irrigation emitter and drip line, and methods relating to same, are provided for reducing the flow and pressure of fluid via an emitter or plurality of emitters defined by two concentric tubes. In one form, the first tube defines an emitter inlet and connected pressure-reducing flow channel and the second tube is extruded over the first tube to enclose the emitter inlet and flow channel and defines an outlet connected to an end of the flow channel opposite the inlet to create an emitter for converting fluid flowing at a high flow rate in the lumen and at the first end of the inlet to a fluid with a low flow rate at the outlet of the emitter. In another form, a drip line is provided having a plurality of such emitters. The emitters capable of being provided with pressure compensation structures to compensate or account for fluctuations in supply line fluid pressure and root growth inhibiting members. Various methods related to the emitter and drip line are also disclosed.

A system and method for harvested water irrigation is provided. The irrigation system generally collects harvested water from a variety of sources and disperses it from a tank to a landscape for irrigation. The irrigation may be managed using a system controller. The system controller interacts with a variety of devices, including a level controller, a pump or valve, and at least one zone valve. The system may be configured to end irrigation cycles in response to certain events and to supplement harvested water irrigation with potable water as needed or selected.
