The following is a list of instructions for residents to follow to avoid expensive plumbing repairs and sewer overflows. Para español, oprime aqui.

  • Scrape food scraps from dishes into trash cans and dispose of in household trash. 
  • Avoid using the garbage disposal for this type of clean up.
