What to do now

  1. Find the deadline and the items cited on the notice. The notice, not this page, sets your deadline.
  2. Call or email the program if anything is unclear, and ask what proof they want.
  3. Book a pump-out if pumping, grease level or records are cited. See 5 pumping companies serving Naperville or the pumper directory.
  4. Keep the signed manifest and your maintenance log. A printable cleaning log helps.
  5. Don't use enzymes or additives to push grease through unless your program allows them; several programs ban them.
  6. Stay ahead of the next one with free pump-out reminders on your city's schedule.
