Sewer Safety

Sewer Safety

Even though some products such as wipes and baby diapers claim to be flushable, they aren't.
Here is a list of some things to keep out of our sewers:

  • disposable diapers
  • tampons or tampon applicators
  • sanitary napkins 
  • cotton balls and swabs
  • condoms
  • cleaning wipes of any kind
  • facial tissue
  • bandages and bandage wrappings
  • automotive fluids
  • paint, solvents, sealants, and thinners
  • poisons and hazardous waste
  • pet waste
  • Unused medications
  • Protect drains from chemical spills — do not use sinks for chemical storage or secondary containment.
  • Fats, Oils, and Grease (FOG)


Grease in sewer pipes causes sewer maintenance problems for property owners and the city.
Never pour grease down your sink drain and try to use your garbage disposal less.

What we will permit down the drain:
The only substances allowed down drains are those that meet all of the following criteria:

  • Nonhazardous
  • No radioactive waste
  • No hazardous chemical waste
  • No untreated biohazardous waste
  • Liquid
  • No solids, sludge, or viscous substances
  • Will not interfere with sewage treatment operations
  • No corrosive pH levels
  • No grease or oil
  • No hot (150°F or higher) temperatures in volumes of more than 10 gallons
