Katy spans three counties along Interstate 10 west of Houston, and it has become one of the region's main distribution and residential growth fronts. The fleets here reflect that split: warehouse and delivery operations on one side, service contractors and corporate vehicles on the other. 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 Katy market
Warehousing and distribution have expanded steadily along I-10 and around the Grand Parkway interchange, bringing box truck and last-mile van fleets that run high daily mileage on a fixed radius. Those fleets are appearance-critical in a way a construction fleet is not: a delivery van is a moving billboard parked in front of a customer's house several times a day.
Served off I-10 and SH 99, in Harris, Fort Bend & Waller Counties.

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 Katy
Katy's newer commercial and industrial parks drain to engineered detention ponds that discharge into the Buffalo Bayou watershed. A wash running to the nearest inlet is putting detergent and hydrocarbon into that pond, on a property with a named owner and a stormwater permit. Sealing the inlets first is what keeps a routine fleet wash from becoming a reportable release.
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.
