Why Smart Irrigation Matters Now More Than Ever

Image

As Southern California enters the peak of summer, water agencies, utilities, and residents are turning their attention to one of the region’s most pressing challenges—sustainable water use. July is officially recognized as Smart Irrigation Month, a national initiative launched by the Irrigation Association in 2005 to raise awareness about the value of efficient irrigation practices. This campaign is more than just a seasonal reminder; it’s a call to action in the face of increasing drought, rising temperatures, and growing pressure on water infrastructure.

In Southern California, where outdoor water use accounts for more than 50% of residential consumption (Metropolitan Water District of Southern California, 2022), Smart Irrigation Month comes at a critical time. With July historically being the month of highest water demand, communities from Irvine to the Inland Empire are rallying around the message: Use water wisely, every drop counts.

What Is Smart Irrigation?

Smart irrigation uses technology, efficient systems, and informed schedules to apply water only when and where it's needed. It’s more than just saving water; it also:

• Reduces water bills
• Preserves local ecosystems
• Extends water supply reliability
• Supports sustainable infrastructure
• Builds climate resilience

The Technologies Behind Smart Irrigation

Many tools that support smart irrigation are eligible for rebates through SoCal WaterSmart. Key technologies include:

• Weather-Based Irrigation Controllers (WBICs): Adjust watering based on local weather conditions
• Soil Moisture Sensors: Water only when soil is dry
• High-Efficiency Sprinkler Nozzles: Minimize runoff and evaporation
• Drip Irrigation Systems: Targeted watering at plant root zones
• Shut-Off Hose Nozzles: Prevent unnecessary water wast

Why July? Peak Water Awareness

While spring is a logical time for system tune-ups, July is ideal for public engagement:

• Highest evapotranspiration—plants need more water
• Mid-season checks help catch inefficiencies
• Strong drought awareness boosts campaign visibility
• High outdoor water use allows better real-time behavior change

7 Smart Irrigation Tips for Homeowners

1. Water early or late (before 6 AM or after 6 PM)
2. Inspect systems monthly for leaks
3. Upgrade to smart controllers and sensors
4. Adjust for seasons—not all plants need the same in July
5. Use mulch to reduce surface evaporation
6. Group plants by water needs
7. Avoid watering pavement—fine-tune your sprinklers

The Bigger Picture: Building Resilient Communities

With extreme heat and prolonged drought becoming more common, water reliability increasingly depends on the smart choices we make every day. As Marco Tule, President of the IEUA Board, emphasizes, “Although drought conditions have subsided, we must remain mindful of water-use efficiency efforts to support long-term water supply needs.” This reminder highlights the importance of maintaining sustainable practices, such as smart irrigation, even during periods of relative water abundance, to foster resilience for the future.

According to the U.S. Environmental Protection Agency’s WaterSense program, households that install smart irrigation controllers can save up to 15,000 gallons of water each year (EPA WaterSense, 2023). On a national scale, if every home in the United States with an automatic sprinkler system were to install and properly operate a WaterSense-labeled controller, the country could collectively save approximately 390 billion gallons of water and up to $4.5 billion in water costs annually—simply by avoiding the overwatering of lawns and landscapes (EPA WaterSense, 2023). When this efficiency is multiplied across thousands of households, the potential impact on water conservation becomes monumental.

Conclusion: A Shared Responsibility

Smart Irrigation Month is more than a seasonal campaign; it’s a long-term commitment to water resilience. Whether you’re a homeowner adjusting your timer or a business investing in upgrades, your choices matter.

Take the pledge to water smart this July—and every month after.
