A Calgary irrigation system requires attention at specific points in the year — miss any one of them and you risk freeze damage, wasted water, or a lawn that suffers in summer heat. This month-by-month maintenance calendar tells you exactly what to do and when.
Calgary Irrigation System Maintenance Calendar — 2026
| Month | Task | DIY or Pro |
|---|---|---|
| January–April | System is off. Inspect controller for display errors. Plan any spring upgrades. | DIY |
| May (startup) | Professional spring startup: pressurize system, zone check, head adjustment, backflow inspection, program controller | Pro — J.G. Irrigation from $75 |
| June | Walk each zone: check for dry spots, poor coverage, clogged heads. Note any heads needing adjustment. | DIY |
| July | Peak season: check for clogged nozzles, adjust for dry patches. Watch water bill for unexpected spikes (= leak). | DIY / Pro if needed |
| August | Begin transitioning to fall schedule (reduce run time by 20-25%). Inspect all heads for damage before end of season. | DIY |
| September | Book and complete fall blowout. Do not wait until October. | Pro — J.G. Irrigation from $90 |
| October | System off. Turn off the backflow preventer shutoff. Controller can be left in hibernate mode or unplugged. | DIY after blowout |
| November–December | System dormant. Note any end-of-season repairs needed for spring. | DIY |
