We administer regulations to make sure the wastewater generated by industries is treated properly. Many industries must pretreat wastewater before sending it to the sewer. This protects the wastewater treatment process, workers, facilities, and water quality.

And it works. Our waterways are cleaner today than in previous decades because business practices have improved.
