Drip Irrigation
Put slow, measured water at the roots of trees, shrubs and beds, with emitters that grow outward as the plants do.
How a drip system is put together
Drip irrigation applies water slowly through emitters placed near each plant instead of throwing it across open ground. The University of Arizona Cooperative Extension describes the parts at the head of every drip zone: a backflow preventer, a filter that keeps particles out of the small emitter openings, and a pressure regulator, because drip works at roughly 20 psi rather than full household pressure. Emitters are commonly rated at 0.5, 1, 2 or 4 gallons per hour, and the rating chosen for each plant matters more than the minutes on the controller.
Good layout groups plants with similar water needs on the same valve, so a desert shrub and a young citrus tree are not forced onto one schedule. Thin micro-tubing runs are kept short; Extension suggests no more than about five feet.
Sun City's water comes from EPCOR wells at 7 to 11 grains per gallon of hardness and is not treated for hardness, according to the 2025 water quality report, so the filter and flushable line ends matter more here than the emitter brand.
Keep the water where the roots are now
Roots spread well beyond the trunk as a plant matures, and Extension's watering guidance notes that most drip systems have too few emitters, placed too close in. Part of drip work is moving emitters out toward the drip line and adding outlets as trees and shrubs grow, rather than lengthening the cycle until the soil near the trunk stays wet.
Maintenance is simple but easy to skip: clean the filter, flush the line ends so grit leaves the tubing, and walk the beds to check that each emitter is wetting the soil it should. Mineral-rich water makes that routine more important, because scale and fine sediment collect in the openings. A drip repair visit compares output at the start, middle and end of each line before any emitter is replaced. New drip zones and conversions from lawn are planned under irrigation system installation, and existing beds that need another valve fall under irrigation zone expansion.

It depends on the tree's size and its water need. University of Arizona Extension guidance for citrus suggests two to six emitters per tree, starting with fewer and adding more as it grows. Move emitters outward toward the drip line over time, because that is where the active roots are.
