Modernization of Wildfire Defence: Integrated Structural Sprinklers and FireSmart Principles

Issue: Escalating structure losses from severe wildfire seasons require a shift in defensive strategy.

Background: Structural sprinklers have been used successfully by the BC Wildfire Service for years, as well as in communities across Canada and globally where wildfire risk is prevalent. This initiative revolutionizes structural protection by utilizing permanently mounted roof sprinklers that emulate natural rainfall, significantly increasing localized humidity and preventing ignition during severe ember storms. Crucially, this setup drastically reduces risk to firefighters, who no longer need to ladder homes and manually deploy sprinklers under hazardous conditions involving advancing fire fronts, dense smoke, and an active evacuation. The high-capacity watercraft, currently in service with the North Westside Fire Rescue serves as a cornerstone of this strategy for waterfront communities. With a dry hydrant system this structural sprinkler protection can be easily extended 300 meters or more for inland structures. Public and private water providers would need emergency back-up generation in the event the fire or the power provider shuts down the power grid.

Solution: For communities connected to municipal style water systems, the proposal implements a rapid-deployment strategy using specialized manifolds attached to fire hydrants. Each manifold allows for the simultaneous connection of 12 to 18 structural sprinkler units. Once activated, a single hydrant provides the necessary pressure and volume to protect up to 18 homes during the strict 20-minute sprinkler cycle. Emergency crews systematically transition between hydrants by shutting down the operational hydrant and activating the next in a pre-planned sequence. The operational scope, including concurrent hydrant usage, is strictly determined by local water system recovery zones and capacities defined during pre-season planning. Expanding this infrastructure to rural properties, the proposal integrates the use of 250- to 270-imperial-gallon water totes. These are strategically positioned near structures or at the end of driveways for refill. Through robust pre-planning, the fire department maintains the supply levels of these tanks if needed, ensuring a reliable water source for the sprinkler systems until the moment evacuation becomes necessary due to fire proximity. Waterfront homes on Okanagan Lake can set up for a marine water supply delivered to their homes through a dry hydrant or hose lay allowing for the Structural Sprinklers to be operated in the same fashion as hydrated areas. The marine asset would be capable of protecting dozens of homes simultaneously. Upon evacuation during maximum risk the system should be activated for maximum protection during maximum risk.

Consultation & Compliance: At the heart of this initiative lies the FireSmart British Columbia program. By aligning community-wide resilience with proven FireSmart principles, property owners are empowered to take actionable steps toward wildfire risk reduction. To qualify for sprinkler installation, residents must complete FireSmart Priority Zone 1 cleanup, up to 10 metres from their structure, which must be certified by the local fire department or BCWS. This rigorous maintenance ensures defensible space around every protected home. During a state of emergency, all water supplies are placed under the exclusive management of the local fire department or BC Wildfire Service, reserving essential resources exclusively for authorized protection crews with a plan. The strategy utilizes strict 20-minute sprinkler cycles every three hours to continuously dampen the immediate environment. This process suppresses falling embers and creates a persistent bubble of humidity, converting high-intensity crown fires into manageable surface fires while maintaining a critical water supply.

Considerations: While evacuation orders in British Columbia are not strictly mandatory, residents who choose to stay behind must remain on their private property. Any resident who leaves their property during an evacuation order will be subject to arrest and removal to prevent unauthorized obstruction of critical hose lines and structural protection equipment. The stay behind would also be isolated from the water supply and NOT connected to the SPU system. Should the stay behind wish to evacuate once the structural Protection System was deployed and activated, they would be restricted to foot evacuation. Vehicles would not be able or allowed to drive over hoses or fire department equipment, part of the educational aspect of the program. This would provide incentive for residents to evacuate while providing positive assurance that significant even substantial measures are being taken to protect their homes.

Benefits: Expedited demobilization allows residents to return within hours instead of days in areas unaffected by structure loss, saving millions in provincial emergency housing costs and preserving our vital housing inventory. Furthermore, by protecting structures from wildfire destruction this reduces chances of a shut down of the power grid therefore protecting our appliances and electronics, this initiative also stabilizes regional insurance markets, mitigating the financial burden of rising premiums and deductibles for all residents, including those in the community's core who could be far from the wildfire urban interface. Finally, the rapid re-entry process alleviates the intense public frustration and animosity typically caused by delayed re-occupancy, fostering greater community trust and cooperation during subsequent wildfire events.

"We must elevate FireSmart from an educational initiative to a fully legislated and operational framework. Protecting our homes from wildfire requires proactive planning and preparation."
