Irrigation System for Large Calgary Properties: 15+ Zone Design Guide

Large Calgary properties — estate homes, acreages, large lots in Aspen Woods, Springbank, and Bearspaw — present irrigation design challenges that standard residential approaches cannot address. J.G. Irrigation's IA-certified design team specializes in large-property irrigation: hydraulic calculation for high zone counts, multi-manifold design, controller selection for 16+ zones, and acreage-specific pipe sizing.

What Makes Large-Property Irrigation Different

Calgary properties with 15+ irrigation zones require a different approach to design than standard 6-8 zone residential systems:

• Master valve required: Large systems run a master valve at the main supply to prevent continuous flow through zone valve bodies when the system is idle — a must-have for systems with high zone counts
• Multiple manifold locations: Long lateral runs from a single manifold cause pressure loss across the zone. Large properties require secondary manifolds placed within 150 ft of the zones they serve
• Pipe sizing calculation critical: Standard 1-inch lateral pipe loses significant pressure across a 400-ft run. Large-property design uses 1.5-2 inch main line with 1-inch zone laterals, sized by J.G. Irrigation's hydraulic calculation
• Controller capacity: Rachio 3 supports 16 zones. Properties with 17-30+ zones require two Rachio 3 controllers or a commercial-tier controller (Hunter ICC2 or Rain Bird ESP-LX). J.G. Irrigation programs multiple controllers to run coordinated schedules
