Willis sits on I-45 just north of Conroe, between the interstate and the north end of Lake Conroe. A1 Mobil covers it from the yard at 255 Blue Bell Rd B, Houston, TX 77037, bringing the crew, the water, the pressure and the containment equipment on the wash vehicle — nothing is supplied by the site.
Construction contractors working continued northward development, small agricultural and acreage operations, and lake-area service businesses.
What gets on Willis equipment
Sandy construction soil and organic residue, plus waterline scum and algae on anything that spends time on the lake.
That is why chemistry and dwell time matter more than raw pressure here. Pressure alone drives contaminant into surface porosity and takes decals and coatings with it; the right detergent given time to work does not.

Wash water compliance in Willis
Drainage runs into Lake Conroe and the San Jacinto watershed, a reservoir that supplies drinking water to the region.
Under the Clean Water Act an unpermitted discharge to surface water is prohibited, and commercial wash water carrying detergent, oil, grease and sediment falls inside that. The discharge happens on your property, from your drainage — so the finding belongs to the site, not to the vendor who drove away. Every A1 Mobil visit seals the inlets first, recovers the water with a 200-foot vacuum system, and hauls it off in a 500-gallon onboard tank.
