Unflushables Damage the Wastewater System

Unflushable items can wreak havoc on the City's wastewater infrastructure. When anything that isn't the 3Ps (pee, poo and toilet paper) is flushed down the toilet, it can create clogs and damage pipes and pumps.

Communities around the world have been affected by massive clogs in their wastewater systems that have a BIG impact. These clogs, which can grow to as big as dozens of metres long and wide, are commonly known as "fatbergs" because of their destructive nature and large-scale size. Workers must spend countless hours removing these clogs, and fixing damaged pipes and pumps before the wastewater flow returns to normal. The wastewater treatment quality can also be compromised, affecting the environment.

Workers must make their way through untreated sewage water to reach these difficult-to-access places where clogs may occur. What starts as minor buildup can quickly turn into a clog that completely cuts off water flow access through clogged unflushables that often include hair, fats, oils and grease, and disposable wipes that don't break down.

The Costs of Removing Clogs
Costs for removing unanticipated clogs and fixing damaged infrastructure is inevitably passed on to residents and businesses through wastewater rate increases.
