Katy's position across three county lines means your load follows the nearest permitted landfill rather than a single city facility. Harris County Pollution Control Services draws the useful distinction: a Type IV site takes construction and demolition debris, trees, brush, and similar dry debris only, while a Type I site takes household garbage as well. The landfills serving the Katy area are privately run and permitted by the state, and the charge at the scale is set by the operator.
For the materials a container cannot take, the public options are county-run. The Harris County Household Hazardous Waste Facility at 6900 Hahl Road, Houston, TX 77040, enter at Hahl Road near 290 and Gessner, is open by appointment to Harris County residents who live outside the City of Houston. Call 346-286-4299 to book, and 346-286-4294 if you want to check for a weather closure.
South of town, the Fort Bend County Recycling Center at 1200 Blume Road, Rosenberg, TX 77471 takes household recyclables, paint, oil, batteries, and appliances from county residents. Its line is 281-633-7581, and it runs Monday, Tuesday, and Thursday through Saturday from 8 a.m. to 4 p.m., closed Wednesdays. It is residential only, so business and commercial loads are turned away. Waller County runs its own drop-off as well.
Your account manager confirms which landfill is taking your container and what the disposal charges look like before the truck leaves the yard.
