How do I calculate how many irrigation zones I need for my Calgary home?
Divide your total lawn area by 2,500 sqft for rotary zones or 1,000 sqft for spray zones. Add separate zones for any gardens, trees, or drip areas. Add 1–2 extra zones for irregular shapes or slopes. J.G. Irrigation calculates exact zone counts at the free site assessment. Call 587-433-4795.
