SPIEDR sprinkler trailers — also called Structure Protection Units (SPUs) — are self-contained, towable trailers pre-loaded with everything a crew needs to defend homes, industrial sites, and communities from wildfire. One trailer can protect up to 50+ structures at once. Every SPIEDR trailer is built in British Columbia and tows behind a full-sized pickup truck.
SPIEDR has manufactured roughly 98% of all purchased Structure Protection Trailers in Canada — built on more than 30 years of operational wildland fire experience.

SPIEDR sprinkler trailers are custom designed trailer units that provide protection from wildfire and can be towed anywhere by a full-sized pickup truck. They are mobile Structure Protection Units, built to protect homes, buildings, and other structures from the threat of wildfire. These structure protection unit trailers are specially designed to be utilized in wildland fire emergencies and come loaded with an inventory of sprinkler equipment that can be separated from the trailer and deployed to wherever it’s most needed. All of the equipment is organized and ready to go at a moment’s notice. SPIEDR sprinkler trailers create a defensible barrier around structures to protect them from the destructive forces of fire.
SPIEDR trailers contain:
- Specially designed sprinklers
- Watertax portable pumps
- Fire hoses
- Miscellaneous adapters, fittings, thiefs, & wyes.
SPIEDR trailers support the operations section under incident command to protect structures during emergencies in the Wildland Urban Interface (WUI), the area where the forest meets the community. SPIEDR is proud to manufacture a variety of Structure Protection Unit trailers, each specifically designed for the different needs for wildland fire suppression.
What's inside every SPIEDR trailer
Each trailer ships pre-loaded, pre-organized, and ready to deploy. Components are sized to the configuration you choose.
- WATERAX portable pumps
- Mark-3 high-pressure pumps and BB-4 fire pumps, depending on the trailer configuration.
- Low-GPM wildfire structure protection sprinklers
- Three sprinkler types, each engineered to wet structures and surrounding fuels without overdrawing the water source.
- Fire hoses
- Pre-coupled and arranged for rapid deployment in active conditions.
- Water bladders
- Configuration-dependent. Supplements on-site water sources where the static supply is limited.
- Adapters, fittings, thiefs, and wyes
- Every coupling needed to integrate with existing water sources and pump configurations on site.
- Anti-slip rear access ramp
- Single rear-load point keeps crews off the roadside of the trailer when staged in active conditions.
A note on WATERAX vs “Wajax.” WATERAX is sometimes searched online as “Wajax Mark-3” — that's a common misspelling. The pumps in every SPIEDR trailer are manufactured by WATERAX, the trusted name in wildland firefighting since 1964. Wajax is an unrelated heavy-equipment dealer.
Every component is organized, labeled, and ready to deploy. Equipment can be separated from the trailer and assigned to different priority areas at the same time — one SPIEDR trailer can defend multiple zones simultaneously.

Every SPIEDR trailer is manufactured in Knutsford, British Columbia and built for Canadian wildfire conditions first.
Equipment that splits across zones
One trailer can defend multiple priority areas at once because the inventory is designed to be unpacked and re-deployed.
Trusted by industry, communities, and government
From oil & gas operations to interface communities, SPIEDR equipment is the default for crews who deploy under pressure.

Frequently asked questions about SPIEDR sprinkler trailers
Quick answers for procurement, operations, and site managers evaluating a SPIEDR Structure Protection Unit.
What is a Structure Protection Unit (SPU)?
A Structure Protection Unit is a mobile, self-contained trailer pre-loaded with the pumps, hoses, sprinklers, and fittings needed to defend buildings from wildfire. Deployed before a fire front reaches a community, an SPU wets structures and surrounding fuels so that airborne embers and direct flame impingement can't ignite the property.
Can a SPIEDR trailer be towed by a regular pickup?
Yes. Every SPIEDR sprinkler trailer is sized to tow behind a full-size pickup — no specialty tow vehicle required. This is intentional: it means a trailer can be moved to a priority area by any crew with a half-ton or larger truck.
What's the difference between a Structure Protection Unit and a fire engine?
A traditional fire engine protects one structure at a time and keeps firefighters in the active fire zone. A SPIEDR SPU sets up sprinklers around dozens of structures, then crews can rotate to the next priority area. One trailer protects up to ~50 homes; one fire engine protects one home.
How many sprinklers does each SPIEDR trailer carry?
Sprinkler counts vary by trailer type — Fire Service Type 1 (~50 homes), Type 2 (~30 homes), Type 3 (~15 homes), Industry Trailer (50+ homes or one industrial site), and 1 KM WETLINE™ (1 km of continuous coverage).
How long does it take to deploy a SPIEDR trailer on site?
Deployment time depends on the trailer type, crew size, and site complexity. Equipment is pre-organized for rapid setup. For specific timing on your site, book a consulting call — we can walk through your deployment plan.
Can a SPIEDR trailer be split across multiple priority areas?
Yes — and this is a key design choice. The pumps, sprinklers, hoses, and fittings can be separated from the trailer and assigned to different priority zones at the same time. One trailer rarely defends one zone; it usually defends several.
Do you rent sprinkler trailers, or only sell them?
We do both. SPIEDR sells trailers outright and also offers fire fighting equipment rentals for seasonal or event-specific needs.
Does SPIEDR consult on which trailer is right for my site?
Yes. Wildfire consulting is one of our core services — site assessments, equipment specification, and deployment planning for industry, resorts, communities, and developers.
