1. Fix leaks and broken heads (fastest payback)
A single broken head or cracked lateral can waste a lot of water every cycle. Monthly inspections catch these. Flow sensors catch them automatically.
2. Change the schedule with the seasons
Many commercial controllers run the same schedule from April to October. Spring and fall need far less water than July. A seasonal adjustment costs nothing.
3. Install a smart controller
Weather-based smart controllers adjust automatically and skip watering after rain. Add a flow sensor to shut off zones with leaks.
4. Upgrade nozzles and regulate pressure
High pressure makes spray heads mist, and mist blows away. Pressure-regulating heads and high-efficiency rotary nozzles put more water on the ground, evenly.
5. Convert beds and islands to drip
Shrub beds, parking islands and narrow strips are where spray wastes the most. Drip delivers water at the roots.
Where to start
An irrigation audit ranks these fixes for your specific property, with prices — so you can take a plan to ownership or the board.
