Canada- Down the Drain Challenge

Environment   Nov 6, 2017 by Rebecca Jin

November 5th, 2017, Sunday

I have recorded what went down in my sink for a whole day, and here are the results

  • What types of things went down your sink?

I had bathroom breaks, hygiene including shower, brushing teeth, washing my face, mouthwash, washing my hands with soap, cleaned dishes for at least 7 times, mopping the floor, washing vegetables and laundry.

  • Estimate the volume of liquids that went down the drain? Did you include a way to measure how much liquid went down?

I used 1000ml cups to measure the amount of water that went down the kitchen drain, it was about 40 cups overall, so 40000 ml (10.57 gallons). But this quantity is only restricted to the kitchen drain. For other utilities, I was unable to measure the volume of liquids.

  • What are the impacts of greywater that goes down the drain? How much clean drinkable water goes down the drain each day?

The impact of greywater that goes down the drain includes substances containing salts, disease organisms, traces of fats and oils (even human body fats), soaps and detergents (which can make the grey water alkaline), and an array of nutrients, some of which could be harmful. Clean drinkable water going down the drain mostly comprise of everything we use it for and since we live in Canada, our water resources are rich therefore most of the water we use is actually drinkable.

  • What is one thing that you can change to reduce water waste?

Save all dishes to clean at once, and first soak the dishes in a pot with warm to hot water, so the bits can come off and sink to the bottom, then just rinse with water and oil soaking wipes to clean remaining residue, therefore saving water, (absorbent oil wipes works well with warm to hot water and you don't need dishwashing detergent, which saves tons of water)

i love the format and detail in your blog! I never realized how many stuff we put down the drain. Another way to reduce water is by taking shorter showers or closing the tap more often.

Great detail in your blog. I like the advice that you gave on how to save water as my parents use this method whenever they wash the dishes. While it can seem like they're saving a lot of water they reverse their positive impacts with their long warm showers.

Great, reflective post! I really like the way you are thinking about your own impact in water waste? Do you think you & your family will change the way you use water? What do you think are the barriers to most Canadians making these small changes?  Have you read or commented on any blogs that thought about household water usage/waste in the same way that you did?

Keep up the great writing!
