Irrigation Usage SupportSmart irrigation systems promise efficiency, water savings, and peace of mind – but only when they’re designed, installed, and used correctly.
Smart irrigation doesn’t guarantee smart results unless paired with thoughtful design and a bit of education. By avoiding these top 5 common mistakes, you the designer can create high-performing systems that won’t just impress clients, but will also provide them with the savings and simplicity they were promised.
1. Failing to Group Zones by Plant and Soil Type
Smart controllers are only as smart as the system design allows. When drip and spray zones, or high- and low-water-use plants, are grouped together, the controller can't make accurate runtime decisions.
Designer’s take-away: Take the time to zone logically during design.

2. Skipping Sensor Integration
Rain, soil moisture, and flow sensors improve system performance dramatically, yet many installations omit the, which limits the controller’s ability to react to real-time conditions.
Designer’s take-away: Include compatible sensors in your spec, and explain their value in simple terms.
3. Not Adjusting for Microclimates
Slopes, sun exposure, wind patterns – each affects how much water each zone needs. Relying on “default” runtimes or treating the whole site the same wastes water.
Designer’s take-away: Call out microclimates in plans, and tailor controller programming accordingly.

4. Overcomplicating the Controller Interface for Clients
Some clients love the tech. Others just want it to work. When a controller is too complex, clients avoid using it – or worse, override your programming.
Designer’s take-away: Choose a controller with a user interface that matches the client’s comfort level. Offer basic training or a cheat sheet.
5. Ignoring Seasonal Adjustments or Maintenance
Smart systems adapt, but they still need human input – especially in changes of seasons or landscaping.
Designer’s take-away: Build in seasonal checkups, and offer a maintenance plan. Like any tool, it works best when cared for.
