Humble sits in northeast Harris County next to George Bush Intercontinental Airport, and the airport shapes the fleet population: ground support operations, freight and logistics companies, hotel and shuttle fleets, and the service businesses working around them. Trailer washout here is booked on site — the crew arrives with the water, the pressure, the power and the containment, and the work happens in your yard.
A trailer that hauled fertiliser cannot take packaged food and a dry van with residue on the floor will have its next load rejected at the dock. Washouts happen in your yard, which removes both the queue at a truck-stop bay and the deadhead trip to reach one.
The Humble market
IAH generates a dense population of commercial vehicles that never appear in an airport's own accounts: air freight and forwarding fleets, courier operations, catering and supply trucks, hotel shuttles, parking operators and ground handling equipment. Most run high daily mileage on a short radius, and most are visibly branded in front of travellers.
Served off I-69/US 59, Beltway 8 and FM 1960, in Harris County.

What a washout involves
Sweep and remove debris
Loose material, dunnage, banding and pallets out first. Washing over debris just relocates it into the water you then have to recover.
Wash walls, floor and ceiling
Hot water and detergent across every interior surface, not only the floor. Residue on walls and ceilings transfers onto the next load, which is the failure most washouts miss.
Rinse and recover
Thorough rinse, then the rinse water is vacuumed out of the trailer rather than allowed to run out of the rear doors onto your yard and into the drain.
Dry and inspect
The trailer is left dry enough to load. A wet dry-van floor damages cardboard packaging, so this step is not cosmetic.
Where the wash water goes in Humble
Aviation-adjacent operations sit under environmental scrutiny as a matter of routine, and fuel, hydraulic fluid and de-icing residue in wash runoff is precisely the category that draws attention. Humble also drains into the San Jacinto watershed above Lake Houston, part of the region's drinking water supply — which makes an uncontained wash here a worse problem than the same wash somewhere else.
Containment is not a line item on the quote — it is how every job runs. Drain seals and booms close the inlets before any water moves, a vacuum system recovers the water from up to 200 feet out, and it transfers into a 500-gallon tank on the wash vehicle that leaves with the crew.
