Irrigation with a Pro

Ask the Right Questions

When hiring an irrigation professional, landscaper or gardener to design, install or maintain your irrigation system or landscape, make sure the contractor understands the building blocks of water-efficient outdoor systems. Start by confirming that the contractor is licensed and bonded, then ask for training and professional certifications.

Here are a few questions you can ask to assess your contractor's skills and experience:

What professional certifications or training have you received that address water efficiency or sustainable landscaping? For instance, have you completed a WaterSense labeled certification program?

If your contactor has a license or professional certification, or has completed training in sustainable landscape design or care, he or she will be better prepared to identify areas of water waste in your landscape.

What are your recommendations for minimizing water waste in my yard?

Listen for suggestions like:

• Use regionally appropriate, drought-tolerant, or native plants that thrive in your climate.
• Add mulch to plant beds.
• Check sprinkler heads for breaks or leaks and make sure water is going where it's needed.
• Test your irrigation system to ensure the zones are programmed correctly.
• Check your irrigation system to look for water efficiency improvements.
• Create an irrigation schedule that makes seasonal adjustments easy.
• Retrofit your irrigation system with new, water-efficient technologies, such as a WaterSense labeled controller, rainfall sensor, or high-efficiency sprinkler nozzles.

Contractors who provide these suggestions demonstrate that they know how to improve the health and water efficiency of your irrigation system or landscape design by using established techniques and new and smarter technologies.

How will you make sure that my irrigation system is watering the right amount for my landscape? Can you provide examples of other sites where you've reduced water waste through better management, plant selection, or irrigation system upgrades?

If your contactor can speak competently about how to improve your irrigation system to meet plants' needs without overwatering and can provide examples from other sites, they are more likely to be capable of moving your landscape toward water efficiency.

Get Results

Learn how to maximize the water efficiency of your irrigation system. As you work with your contractor, educate yourself by asking your contractor these questions:

• How do I adjust my irrigation controller to apply the least amount of water necessary to promote deeper root growth and build drought tolerance in my yard?
• Is a "smart" irrigation controller, such as a WaterSense labeled model, right for my landscape? How will it help me save water and money over the long term?
• Do some irrigated areas (e.g., zones) in my yard require more water than others? Can I cut off irrigation to some of my established plants and just water by hand when necessary? Can you show me how to set my controller so I water only the zones that need it and not the zones that don't?
• I've heard that my yard's water needs vary throughout the year. Can you show me how to adjust my irrigation system with the seasons? Can you provide a written irrigation schedule that also accounts for seasonal changes?
• Should I still water my yard in the cooler months? Or should I winterize my irrigation system? If so, when and how?
• Can you recommend a few native plants that will both thrive in my climate and provide beautiful accents to my yard?
• What else can I do in my yard to use less water? Can you recommend any smart practices, alternative plants or groundcover, or maintenance options that will help me be more water-efficient?
