An apparatus and system for irrigation is disclosed. The Save-A-Tree-System Apparatus is an apparatus for sub-surface irrigation which uses a rigid or semi-rigid tube with a plurality of fluid emitters disposed in the tube, which is buried in order to deliver irrigation to the root-zone of plants, which can be connected in series to efficiently direct irrigation to multiple locals, and which has an internal reservoir for the application of fertilizer, pesticide, fungicide, or the like, to an individual location to supplement system-wide treatment. Irrigation water or treated water is delivered from a source to the Save-A-Tree-System Apparatus via a connecting hose. A pressure regulator, filter and/or directional flow check valve may also be installed between the source and a Save-A-Tree-System Apparatus as needed to control the irrigation water that is delivered to the apparatus. The Save-A-Tree-System Apparatus may also simultaneously provide both aboveground and sub-surface irrigation and aeration.
