Big White Irrigation Blowout Quotes
At alpine elevation this is the service that matters most, and timing is nearly the whole discipline. Hard frost can arrive before the end of September, so a blowout scheduled on valley timing is already too late.
Winterization is the one seasonal service where being late is genuinely costly — and being early costs nothing at all. At Big White's elevation, irrigation is almost entirely a question of timing — which shapes what winterization work here usually involves.
Commonly requested here
Winterization work on Big White properties
- Scheduling well before the valley's usual blowout window
- Thorough clearing appropriate to severe freeze exposure
- Full draining of every above-ground component
- Service arranged for absentee and vacation owners
- Confirmation that nothing is left holding water
Worth knowing
At this elevation there is no meaningful late option. Once you have stopped watering, the correct time to blow out is immediately — waiting gains nothing and risks the entire system.
Issues that come up in Big White
- Late ground thaw delaying spring start-up well past valley timing
- Unexpected shoulder-season cold snaps threatening pressurised systems
- Absentee ownership meaning faults go unnoticed for long periods
Local context
- Big White Ski Resort sits at roughly 1,750 metres, dramatically higher than the Okanagan valley floor, with a correspondingly short frost-free season.
- Hard frost can arrive well before the end of September and snow can persist into late spring, compressing the service window at both ends.
- Most properties are vacation, chalet or strata holdings whose owners are frequently not on site.
At roughly 1,750 metres the frost-free season is dramatically shorter than the valley's; hard frost can arrive in September and snow can persist into late spring.

Questions
Winterization in Big White
What is an irrigation blowout?
An irrigation blowout is the process of forcing compressed air through an irrigation system to push out every bit of water left in the pipes, valves and sprinkler heads before winter. A contractor shuts off and isolates the water supply, connects a compressor at the blowout port, then opens each zone in turn until only air and mist come out of the heads. It is done because water expands as it freezes, and buried pipe is the most expensive possible place to discover that.
What does an irrigation blowout cost in the Okanagan?
We do not publish prices, because the work is quoted by independent contractors and the number depends on the property. The things that move it most are the number of zones, the length of mainline, whether there is a pump, filtration or an above-ground backflow assembly to drain, how accessible the blowout port and valve boxes are, and how late in the season you book. Requesting two or three quotes is the reliable way to find out what your system should cost, which is what this service is for.
When should an irrigation system be blown out?
Before the first hard frost, which in the Central Okanagan valley usually means sometime in October — earlier at elevation. Because being early has no downside once you have stopped watering and being late risks cracked pipe, the sensible approach is to book toward the early end of the window rather than waiting for cold weather to force the decision.
Can I just drain the system instead?
Draining alone is not sufficient on most systems. Even with drain valves and favourable grade, laterals and low points retain water that gravity will not remove, and it only takes a small amount in the wrong place to crack a fitting or a valve body. Compressed air is used because it clears water that draining leaves behind.
