Just because it fits in the drain, doesn’t mean it should go down it. A lot of things we use every day, even if they’re labeled ‘flushable’, can cause big headaches for both of us if this happens.
Our sewers aren’t designed to be a garbage disposal system.
Why it matters
Toilets, sinks, and storm drains all lead to our sewer system. When items end up there that don’t belong, they can clog up pipes. This can lead to sewer backup into homes.
Damage can also be done to our infrastructure, including our underground pipes and wastewater treatment facilities. That can cost a lot of money to repair.
What ends up down the drain can also eventually end up in our rivers. This impacts the health of our waterways.
To prevent all that from happening, let’s break down what should never go down the drain.
The biggest culprits
Even though disposable wipes are labeled “flushable”, they really aren’t. The same goes for paper towels and disinfectant wipes. Because these things don’t dissolve, they can get stuck and cause clogs.
Clogs can also be caused by grease, fats, and oils.
“Oil and grease really wreak havoc on our collection systems,” said Susan Lambert, Field Service Operations Engineer.
You should not be frying up bacon in your pan then pouring it down the drain. Instead, put it in a jar and then into the garbage.
Food scraps are another no-no. Consider composting them or bringing them to our food waste drop-off locations, instead of tossing them in the trash, if you can.
Other things that should never go down the drain are cigarette butts, dental floss, latex gloves, feminine hygiene products, including tampons and applicators, and condoms.
Hair can also cause issues if there is too much, so it’s a good idea to put a hair catcher on your drains.
You can get rid of unneeded medication by taking it to any pharmacy. Chemicals and hazardous materials can be safely disposed of at our 4R Winnipeg Depots.
Strange but true
With so many drains leading into our sewer system, it’s inevitable that a few odd things have ended up there.
Our screening system has pulled out various pieces of jewelry. Reptiles have also been found in our sewer. For anyone who has kids, it’s not surprising that toys like Lego make regular appearances.
One customer called asking if we could get their dentures back, after they accidentally flushed them down the toilet. Another called asking if we could get their cellphone back.
“They said they accidently dropped their cellphone down a storm drain and were wondering if we had found it,” said Lambert. “I don't think we did.”
Unfortunately, we can’t reunite you with items found in our sewers.
Outside of your home
You should also be careful with the storm drains on the streets. Putting things like grass clippings, leaves, and other yard waste down there is against one of our by-laws.
Make sure any vehicles you have aren’t leaking fluids like antifreeze, oil, and gas onto the street.
Find a nearby garbage or recycling can, instead of littering. And please pick up after your pets.
