What items should not be flushed into the sewer system?

It is not recommended to flush household grease, oils or other fats into the sewer system as they congeal and can clog either the household line or the sewer main. The Village of Cold Spring Sewer Code requires commercial properties to have and maintain a grease trap. Also, disposable wipes are not disposable in the sewer system. They take years to decompose and can clog pumps and block lines.  Medicines, both prescribtion and over-the-counter, should never be flushed into the system.
