What not to flush down sinks, drains, and toilets

Be careful about what you flush down your sinks, drains and toilets. The wrong liquid or solid waste can cause a lot of problems for your home - clogged pipes, reduced plumbing flow, odours or a sewer back-up.

Disposing of some waste, such as fryer grease can also cause a lot of problems for Calgary's wastewater system and even the environment. Learn more about the proper way to dispose of fats, oils and greases (FOG) by visiting our FOG for Homeowners page.

Keep these items out of your sinks, drains or toilets

Food waste

  • Fats, grease and oils (deep fryer oil, vegetable oil, cooking oil)
  • Lard, butter, salad dressing, marinade for meats
  • Vegetables, meat, pasta, bread, and other food waste items

The best way to dispose of oils is to pour them in a container such as tin can, empty coffee cup or milk carton. Place it into the trash once the container is cooled.

Leftover grease and oil should be removed from pans before washing them. Save water and soap by using a napkin to wipe them clean.

Bathroom items

  • Diapers, wet wipes, rags, bandages
  • Dental floss, cotton swabs, condoms, cosmetics
  • Personal hygiene products (tampons, applicators, sanitary napkins)
  • Pills and medicine - expired prescription medication

Pills and medicine should be returned to your pharmacist for disposal.

Household items

  • Cigarette butts, paper towels
  • Children toys

Hazardous waste

  • Bleach and ammonia
  • Clean solvents and spot removers
  • Disinfectants
