If you're running — or starting — a pressure washing business in Houston, wastewater compliance isn't optional. Houston has some of the strictest pressure washing regulations in Texas, and violating them can cost you up to $10,000 per day.
Here's exactly what the rules are, who enforces them, and how to stay compliant.
The #1 Rule: Nothing Goes Down the Storm Drain
You CANNOT discharge pressure washing wastewater into storm drains. This is a federal, state, AND local violation with serious penalties.
Storm drains flow directly into Houston's bayous, rivers, and eventually Galveston Bay — untreated. Pressure washing wastewater contains oil, grease, paint chips, cleaning chemicals, and heavy metals from surfaces you clean. Dumping this into the storm drain system violates:
- The federal Clean Water Act — enforced by the EPA
- Texas water quality regulations — enforced by the Texas Commission on Environmental Quality (TCEQ)
- City of Houston stormwater ordinances — enforced by the Houston Health Department
Who Enforces This?
Two agencies regulate pressure washing wastewater in Houston:
| Agency | Role | Penalty |
|---|---|---|
|
TCEQ Texas Commission on Environmental Quality |
Statewide water quality enforcement | Up to $10,000/day per violation |
|
Houston Health Dept FOG Program |
City permit enforcement, monthly reporting | Permit revocation + city fines |
What You're Required to Do
1. Capture all wastewater
You must use containment equipment to prevent any runoff from reaching storm drains:
- Containment mats or berms — placed around the work area to capture runoff
- Wastewater recovery system — a vacuum/pump system with a reclaim tank that collects the captured water
- Boom barriers — for larger job sites to contain runoff before it reaches drains
The City of Houston will inspect your equipment before issuing your permit. They test your booms, mats, and recovery systems to verify they actually work.
2. Dispose of wastewater properly
Captured wastewater must be disposed of through approved channels:
- Sanitary sewer — wastewater CAN be discharged to the sanitary sewer system (not storm drains) with proper filtration. Contact Houston Public Works for guidance.
- Licensed disposal facility — for heavily contaminated wastewater (paint stripping, degreasing)
- Never to storm drains, ditches, creeks, or open land
3. File monthly reports
As a permitted operator, you must file a monthly waste activity report by the 15th of each month. This report must include all regulated waste activity generated within Houston city limits and transported by your company.
Failure to submit monthly reports can result in permit revocation.
4. Use compliant chemicals
- All detergents, degreasers, and cleaning agents must be EPA-compliant
- You must maintain Safety Data Sheets (SDS) for every chemical you use
- Some chemicals require additional TCEQ permits — verify before using
Equipment Costs for Compliance
| Equipment | Cost Range |
|---|---|
| Containment mats/berms | $300–800 |
| Wastewater recovery system (reclaim tank + vacuum) | $1,500–4,000 |
| Boom barriers (for large sites) | $200–600 |
