Help Prevent Sewer Backups​

Flushing wipes, paper towels and similar products down toilets will clog sewers, cause backups and overflows with internal plumbing and within the Town system.  Even wipes labeled as "flushable" will clog pipes and interfere with the sewer collection system and pumps. Please dispose of these items in the trash. 

Please NEVER Flush:

  • Paper towels, disposable wipes, washcloths and rags
  • Any synthetic materials such as plastic, which do not decompose or dissolve
  • Feminine products
  • Cotton balls or cotton swabs
  • Unused medication or syringes
  • Fats, oils and grease
