Say no to FOG to avoid a holiday clog

December 20, 2021

Public service announcement

'Tis the season for savoury, saucy and delicious foods. We may enjoy FOG (fats, oils, grease) for added flavour during the holiday season, but for drainpipes and sewer systems, it can cause severe indigestion. 

When poured down the drain, fats, oils and grease (FOG) stick to the inside of sewer pipes and can build-up over time, blocking entire pipes. This holiday season, residents are reminded to keep FOG out of sink drains. 

Not only can FOG cause blockages in your household plumbing, it’s also the number one cause of sewer blockages and overflows in the city.  

Residents can help prevent FOG-induced backups and keep our wastewater collection systems running smoothly by following these simple steps: 

  • Cool it, can it, trash it. After cooking, put cooled oil or grease into a can or container and dispose of it in the trash. Never pour grease down a drain. 
  • Put baskets/strainers in sink drains to catch food scraps and other solids and empty them into the garbage.
