Pretreatment 101 Training - Upcoming In-person Workshops

EPA sponsors several Pretreatment 101 trainings throughout the country each year. Whether you are new to pretreatment or desire a refresher, all are welcome to attend these trainings, though priority is given to municipal, state, and federal employees.

Workshops include two days of instruction, but may be spread over one full day and two half days depending on space availability. Workshops are an instructor-led classroom format that includes collaborative group exercises, question and answer sessions with experienced pretreatment personnel, and networking breaks. See each workshop's timing and details on its registration page below.

Course Information

  • Workshops are FREE, but registration is required.

Pretreatment 101 - Recorded Webinars

The intended audience is regulatory and municipal personnel with fewer than five years of pretreatment experience. More experienced personnel and industrial user personnel who are responsible for the wastewaters discharged to a POTW will also benefit from these webinars.

Although the webinars may be viewed in any order, we recommend the following order for people who are relatively new to pretreatment:
