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. Engine degreasing 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.
High-mileage tractors earn their degreasing interval: a clean bay turns any new wetness into a signal, which is worth more on a unit running 100,000 miles a year than on one that idles in a yard.
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.

How it is done safely
Protect what water must not reach
Alternator, air intake, ECU and exposed connectors are covered before anything is applied. This is the step that separates degreasing from creating an electrical fault.
Apply degreaser and let it work
A solvent-based degreaser at moderate temperature, given real dwell time. The chemistry breaks the bond; blasting it with pressure instead drives grease deeper and pushes water where it should not go.
Low-pressure rinse
Rinsed at low pressure and controlled angle. High pressure into an engine bay forces water past seals and into connectors — the reason people believe engine washing is risky is that it is usually done this way.
Recover the runoff
Engine bay runoff is oil-bearing water. It is contained and vacuumed back rather than allowed to reach the ground, which on this service is not optional.
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.
