Drip irrigation is the right choice for desert landscape beds, xeriscape, established trees, and shrub areas on Phoenix rental properties. Spray and rotary sprinkler systems are required for Bermuda and Zoysia turf areas.
Most Phoenix properties need both. The question is not which system to choose—it is knowing which zones need which system and how to run them efficiently together under the restrictions of Phoenix Water Services.
Quick Summary
- Drip is 30-50% more water-efficient than spray for the same plants in Phoenix summer heat. Use it for all non-turf areas
- Spray and rotary sprinklers are required for Bermuda turf. Drip cannot water turf effectively
- Most Phoenix rental properties have both systems and should run them on separate controller programs
- Under Stage 2 drought restrictions, drip systems are often exempt from spray-system watering day limits. Confirm the current Phoenix Water Services exemption schedule before setting your program

Drip vs. Sprinkler at a Glance #
| Factor | Drip Irrigation | Spray / Rotary Sprinkler |
|---|---|---|
| Water efficiency | 90%+ of water reaches root zone | 50-75% efficiency; evaporation and wind drift reduce delivery |
| Best application | Desert beds, shrubs, trees, xeriscape | Bermuda and Zoysia turf areas |
| Installation cost | $225-$900 per zone | $400-$1,200 per zone (more components, trenching required) |
| Maintenance frequency | Emitter checks seasonally; lower ongoing maintenance | Head checks before each season; heads break more often |
| Monsoon compatibility | Less affected by wind and debris impact | Heads can be displaced by debris and soil movement |
| Stage 2 restriction exposure | Drip often exempt from watering day limits | Subject to odd/even day limits and time restrictions |
| Fungal disease risk | Low — water delivered at root zone, not foliage | Higher — wet foliage if timing is wrong |
What Each System Does #
- Drip irrigation delivers water directly to the root zone of individual plants through low-flow emitters installed at or near each plant’s base. The emitter releases water at a slow, steady rate — typically 0.5 to 2 gallons per hour — allowing the soil to absorb moisture without runoff or evaporation. The tubing runs along the soil surface or just below it through landscape beds.
- Spray and rotary sprinkler systems distribute water over the turf canopy using pressurized heads that pop up during each irrigation cycle. Fixed spray heads cover a defined arc up to 15 feet. Rotary heads cover arcs up to 35 feet and rotate during the cycle. Both are designed to provide head-to-head coverage across the entire turf surface, which is what Bermuda grass requires because it grows uniformly across the full soil surface.
Water Efficiency: Why Drip Wins for Phoenix Desert Landscape #
Phoenix summer creates extreme evaporation conditions that make spray irrigation inefficient for non-turf areas. At temperatures above 110°F and single-digit humidity, a spray head delivers water above grade, where 20-30% evaporates before reaching the soil. Wind drift adds additional loss to properties without wind barriers.
Drip irrigation bypasses the evaporation zone entirely. Water is delivered at ground level, directly to the root zone, where the soil holds it against the heat. Studies from Arizona State University extension programs show that drip irrigation saves 30-50% more water than spray irrigation for the same plants under desert conditions.
For Phoenix rental properties operating under Stage 2 drought restrictions, water efficiency is not just an environmental preference—it is a compliance and cost management tool. Drip systems use less water per plant and are often classified differently from spray systems under Phoenix Water Services restriction schedules.
Where Sprinklers Are Required: Bermuda Turf #
Drip irrigation cannot effectively water Bermuda or Zoysia turf. These grasses grow in a dense mat that covers the entire soil surface. Effective irrigation requires water to be distributed uniformly across the entire turf area—which requires spray or rotary-head coverage, not point-source emitters.
Bermuda turf in Phoenix in summer needs 3 irrigation cycles per week at 0.5-0.75 inches per cycle under normal conditions. Under Stage 2 drought restrictions, watering days are limited by address, which changes the scheduling approach. A spray or rotary system on an ET-adjusting smart controller handles this scheduling complexity automatically.
Phoenix rental properties with Bermuda turf zones need a spray or rotary system for those zones. Drip is appropriate for all non-turf areas on the same property.
Operational Insight
The most common Phoenix rental property irrigation setup: spray or rotary heads on turf zones, drip on front and back desert beds, and separate controller programs for each. Running drip and spray on the same program is the most common scheduling mistake we correct on portfolio properties — the two systems have different cycle lengths and frequency requirements.
Maintenance Requirements: Where the Systems Differ #
Drip systems have lower ongoing maintenance costs than spray systems. The primary maintenance tasks are emitter checks (clogging from Phoenix mineral-heavy water), filter cleaning (quarterly in most Phoenix installations), and tubing inspection for rodent damage (a specific Phoenix issue—desert rodents chew through drip tubing). An annual emitter and filter check covers most maintenance needs.
Spray systems require more frequent attention. Phoenix conditions generate specific maintenance demands: head displacement from monsoon debris, cracked risers from soil movement during monsoon saturation and drying cycles, and head-to-head coverage drift as heads settle over time. A pre-season zone run before June identifies most issues before they cause turf damage.
Installation Cost Comparison for Phoenix Rental Properties #
- Drip installation: $225-$900 per zone. Lower cost per zone because the system requires no underground head piping — tubing runs above ground through landscape beds and connects to the supply line at the valve.
- Spray/rotary installation: $400-$1,200 per zone. Higher cost because underground head supply lines must be trenched to each head location. Phoenix caliche soil increases trenching costs compared to softer markets.
- Hybrid installation (both systems on one property): Total cost depends on the number of zones of each type. A typical Phoenix rental property with two turf zones (spray, $800-$2,400) and two desert bed zones (drip, $450-$1,800) runs $1,250-$4,200 total for a new installation.
Best For: Properties with Desert Landscaping (No Turf) #
A Phoenix rental property that has been fully converted to desert landscaping—decomposed granite, desert shrubs, cacti, and established trees — should run a drip-only irrigation system.
There is no reason to run spray heads on a property with no turf. Drip covers every plant more efficiently, uses less water, requires fewer repairs, and is the preferred system of Phoenix Water Services for desert landscapes.
For properties currently on spray irrigation with no turf (a common situation on older Phoenix properties with landscape-converted front yards still running the original spray system), a spray-to-drip conversion is the most cost-effective improvement. The existing supply lines and valves are reused; only the head connections are capped, and drip tubing is installed.
Best For: Properties with Bermuda Turf #
A Phoenix rental property with Bermuda turf zones needs spray or rotary coverage for those zones. The correct hybrid approach: rotary or spray heads on turf zones, drip on all landscape beds and tree zones, separate controller programs for each system type, and an ET-adjusting smart controller to automatically handle Phoenix Water Services restriction compliance.
We design and install both systems and handle the controller programming to run them correctly as separate programs. For properties where the current system configuration is unknown, we run an irrigation diagnosis that maps the existing zones and identifies which areas need drip versus spray. Property managers coordinating irrigation assessments across multiple Phoenix addresses use our single-point scheduling.
Drip, spray, or hybrid — we assess and design the right system for each property.

Frequently Asked Questions #
Can I use drip irrigation for a Bermuda grass lawn in Phoenix? #
No. Bermuda turf grows in a dense mat across the full soil surface and requires uniform water distribution that only spray or rotary heads can provide. Drip emitters deliver water to specific points, which creates dry strips between emitter locations on turf. Use spray or rotary heads for all Bermuda and Zoysia turf areas.
Is drip irrigation subject to Phoenix Stage 2 watering restrictions? #
Drip systems are often treated differently from spray systems under Phoenix Water Services’ conservation and restriction schedules, but the specific exemptions and rules vary with drought stages. Confirm the current drip exemption status directly with Phoenix Water Services or through a licensed irrigation contractor familiar with the current restriction schedule before programming your drip zones.
How much water does drip irrigation save versus sprinklers in Phoenix? #
Drip irrigation saves 30-50% more water than spray irrigation for the same plants in Phoenix desert conditions. The savings come from eliminating above-grade evaporation (which consumes 20-30% of spray water in 110°F heat) and delivering water directly to the root zone where the soil holds it.
What type of irrigation system do most Phoenix rental properties have? #
Most Phoenix rental properties have a hybrid system: spray or rotary heads on Bermuda turf zones and drip on desert landscape beds. Older properties may have spray heads on landscape beds that have since been converted to desert plants, which is the most common candidate for a spray-to-drip conversion on a Phoenix rental property.
