What not to flush down sinks, drains, and toilets

The City of Calgary is asking homeowners to work with us in avoiding unnecessary repairs to home and City sewer (wastewater) systems by flushing only toilet paper and human waste down toilets. This will allow our limited crews to focus on the delivery of essential services and maintain social distancing guidelines.

  • Flushing anything other than pee, poo, and toilet paper down the toilet can clog pipes and create sewer back-ups, which can be costly for both homeowners and The City of Calgary.
  • Wipes that claim to be flushable aren’t. After they’re flushed, they don’t break down like toilet paper does. Toilet paper will disintegrate after it’s flushed, but so-called “flushable” wipes retain their shape and strength, causing blockages in pipes.
  • Facial tissue (Kleenex), serviettes and paper towel cannot be flushed down your toilet. They do not break down as toilet paper does, and lead to clogs and sewer back-ups.
  • Wipes, paper towel and all other items used as a toilet paper alternatives should be bagged and disposed of in your black cart. They do not belong in your green or blue bins.

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.
