Landscape irrigation typically accounts for 50–70% of residential water use in Arizona. With water rates in the Phoenix metro continuing to rise, a properly designed irrigation system isn’t just a convenience — it’s a financial necessity.
Why Most Irrigation Systems Waste Water
The typical irrigation system installed with a home was designed to water on a fixed schedule — ignoring temperature, rainfall, humidity, seasonal changes, and soil moisture. The result is typically massive overwatering in spring and fall and potentially underwatering during peak summer heat.
Smart Controllers: The Foundation of Efficient Irrigation
A smart irrigation controller adjusts watering schedules automatically based on real-time weather data. Studies by the EPA’s WaterSense program show smart controllers reduce outdoor water use by 15–40% compared to conventional timers — translating to $200–$600 per year in savings for a typical home.
Drip Irrigation vs. Spray Heads
One of the most impactful changes you can make is converting spray heads to drip irrigation in planting beds. Spray heads lose significant water to evaporation and wind drift. Drip irrigation delivers water slowly and directly to the root zone, where plants can actually use it.
