Quiz Answer Key and Fun Facts

Answer: Wet wipes

Fatbergs started to become a problem when disposable wet wipes were used regularly. Sewer workers coined the term, coming from fat and berg, modelled after iceberg. Of course, an iceberg is something much nicer to look at.

2. How do fatbergs form?

Answer: Alkaline fluids turn fat and assorted insoluble matter into a solid substance

Fatbergs can be as solid as concrete. Some fatbergs take months to remove with special equipment.

3. If they weren't so hard to remove, fatbergs could be a good source of what?

Answer: Biogas and biodiesel

A fatberg found under London in 2017 was almost completely turned into biodiesel. The leftover piece is now on display in a museum.

4. It is fine to flush leftover food down your toilet.

Answer: False

While food will break down eventually, it is definitely not a good idea to flush it as it can still cause clogs. Human waste is already broken down and the whole plumbing system is designed for that, and not as a replacement bio-waste bin.

5. There are also harmful chemicals in the sewers. Besides cleaning products, where do those come from?

Answer: Each of these causes pollution

Antibiotics simply flushed away is one of the reasons bacteria develop resistance. The amount in the sewers is not enough to kill them; instead it helps those bugs to develop coping mechanisms. Hormone products get into freshwater and cause changes to fish. Cigarette butts release all the bad stuff they filtered from the smoke, including nicotine and heavy metals.

Not to mention they also add to the clogging. Cosmetics add to both clogging and pollution as well. Especially bad are cotton pads and buds.

6. Some sewage treatment facilities do find which valuable resources in ash from burned sludge?

Answer: Gold, silver, copper, zinc & other metals

In the city of Suwa in Japan, about two kilos of gold per ton of ash is extracted. There are gold mines with lower output than this. Unfortunately, only a few facilities work to retrieve these resources.

7. Used coffee grounds are fine to flush down the toilet and even help with de-clogging.

Answer: False

Coffee grounds contain a lot of fat, so even if you flush with lots of water, while it will likely not clog your own pipes, it will add to the fatberg problem.

8. After heavy rain, city hospitals often see an influx of which of these?

Answer: People sick with stomach bugs

In heavy rain, sewer systems are often out of capacity. This causes overflow of sewage into rivers and streets. Bacteria getting into fresh water, and areas where people work and play, is a growing problem and leads to more people with gastroenteritis.

9. You may suspect a broken sewer pipe under your garden if you notice which of these?

Answer: Patches of grass are extra lush and green

Sewage is a good fertilizer, despite the chemicals in it. So your lawn will love it, but you still get the pipe fixed as soon as possible.

10. You just flushed, and the toilet makes weird gurgling noises. What's happening?

Answer: Most likely, there is a clog

Clogs can cause suction due to negative air pressure. When it is released, it causes the gurgling, and the toilet usually flushes unless the blockage is already too massive. If this happens more than once and you can't find the cause with available tools, contact a plumber and, if relevant, your neighbors.
