Pretreatment Program

About

In an effort to protect our treatment works and the quality of our rivers and streams, the Pretreatment staff permits inspects and monitors over 40 industries. The Pretreatment Program administers regulations to make sure the wastewater generated by industries is treated properly. Many industries must pretreat their wastewater before sending it to the sewer. This helps to protect the wastewater treatment system, our employees, the facilities as well as help to ensure that clean, quality water is discharged.  Because of our relationships with local industries and their commitment to protecting the environment, our waterways are cleaner today than in previous decades because business practices have improved.
