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. It can also cause environmental damage and expensive repairs for Calgary's wastewater system

Keep these items out of your sinks, drains or toilets:

Dispose fats, oils and grease into your green cart

  • Residential quantities (two litres or less​) of fats (lard, butter), oils (salad dressing, marindate for meats) and grease (deep fryer oil, vegetable oil, cooking oil) should be disposed of in the green cart, not the black cart.
  • Always wipe cooking equipment and scrape dishes before washing.
  • Solidify your oil by mixing it with an absorbent material such as paper towels, then place it in a certified compostable bag or paper bag and place it in your green cart.

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
