Texas waste water laws

Hey guys, I am new to the pressure washing business. What are the laws for cold water systems?
Do I need a recovery system or just watch what chemicals I use? How do you guys deal with this?

Every state, county, and even city will have different rules and regulations. Your best bet is contact local agencies to find out exactly what you need to do. I doubt a cold water unit will have any different regulations than a hot water unit. They don’t only worry about the chemicals being used but also the dirt and grime you’re washing away.

If needed there are reclaim systems that reclaim or filter the water.

@Jordie posted a good video on here reclaiming his wash water when doing a Wendy’s restaurant. It’s definitely worth watching.
