How it Works
Creating A Protective Moisture Zone
CREATING A PROTECTIVE MOISTURE ZONE
When a wildfire is close, embers can blow far ahead of the flames and land on roofs, decks, trees, or dry ground. The WET Defence system uses your water source, like a lake or river, to soak your property and increase humidity. This makes it harder for embers to find dry spots to ignite. We call this area your Protective Moisture Zone.
The Protective Moisture Zone is made up of:
The Pump
A stand-alone pump runs on gas or diesel, so it works even if the power goes out. It draws water from your lake or river.
The Lines
A high-pressure hose moves the water from the shoreline to your buildings and property.
The Sprinklers
Roofline sprinklers soak your roof, walls, and eaves, which are the spots where embers usually land.
Tripod sprinklers are made to soak trees and the ground cover around your buildings.
Adjustable 360-degree sprinkler heads cover a wide area, and we set them up to fit your property.
The Protective Moisture Zone
When the sprinklers are on, your roofs, walls, plants, and ground all get wet, and the humidity goes up around your property. Wet surfaces are harder for embers to ignite. The system keeps working as long as the pump has fuel and water.
Designed Around You
Every property is unique. We start by looking at your layout, buildings, and water source. Then we design, install, and maintain the system, and train the people who will use it.
Being prepared lowers your risk, but it does not guarantee your property will survive a wildfire. Always follow evacuation orders.
You may already have a portable pump in the boathouse, whether it’s a Honda or another brand, or a setup pieced together over the years from whatever hose and fittings were on hand. It’s a good start. But a pump on its own isn’t a plan, and equipment that was never designed to work together can be slow to deploy and hard to rely on when it matters most.
We can help you trade up. Let us know what you have and we’ll assess it against your property, your water source and your needs. Then we’ll upgrade you to a professionally designed pump and sprinkler system built specifically for your cottage.
What an upgrade looks like
We assess your water access, property layout and vulnerabilities.
We design a system matched to your pump, hose and sprinkler needs, including how far the water has to travel and where it needs to go.
We install it, train the people who will use it, and monitor and maintain it over time.
Remote start set-up, so you can start your pump from your phone, wherever you are.
Trade-in options are available on your existing equipment. [Add details: eligible equipment, credit or discount, how it works.]
Not at the cottage when something looks wrong? With remote start, you can start your pump from your phone, so your system can get going while you’re still on your way. It’s one more way to make sure your equipment is ready when you need it, even when you’re not there.
Already have a pump? Let’s upgrade it into a system.
We’ll look at what you have, tell you what’s worth keeping, and show you what a system designed for your cottage would look like.
Jasper, 2024. CFJC Today / The Canadian Press, July 23, 2025: a homeowner ran a rooftop sprinkler for two days, and the fire chief said the property was “pretty moistened by their sprinklers.” The homeowner credited luck, and shifting winds also helped.
Jasper, 2026. The Jasper Local, May 21, 2026: the fire department’s sprinkler program. Captain Nik Kellis says sprinklers “can help prevent ember ignition by wetting down” and are “not” protection against radiant heat. In 2024, firefighters switched on sprinklers at properties that had them, and they ran throughout the fire.
Prince Albert, Saskatchewan, 2021. Prince Albert Daily Herald, May 25, 2021: sprinklers on homes helped Birch Lane survive. The fire chief said that without them, “it would have been impossible.”
Northern Saskatchewan, 2015. Cottage Life, July 17, 2015 (updated 2024): a couple saved their lakeside cabin with industrial sprinklers over two weeks. This is the closest match to your audience.
Palisades Fire, California, 2025. Spectrum News, March 24, 2025: Frontline says 40 homes with its system were saved. The 40 figure comes from the company, so attribute it to them.
