A Water Droplet’s Story: Where Does Water Go After People Use It?

Do you ever wonder where the water goes after you wash the dishes or flush the toilet?

Actually, wastewater goes to domestic sewage treatment systems in your city.

However, the journey to a sewage water system is a long way. In fact, your government is spending millions of dollars to keep and to maintain wastewater treatment systems.

If you’re curious where the water goes after you flush the toilet, then this article will tell you the story of Droppy and his journey from the faucet to the commercial waste water treatment system.

From the water reserve

Droppy is a cute water droplet in the city’s water reserves. One day, Droppy found his way into a household. Apparently, the pipe he entered into went straight ahead of the washing machine.

For several spins, Droppy whirled around, and his body was filled with bacteria, dirt, and laundry detergent. Then after he served his purpose, he was flushed out of the washing machine.

On to the sewer main

Droppy entered small pipes until he reached a dark place. This mysterious place is called the sewer main.

The sewer main is a series of large pipes that span 3-5 feet in diameter. These pipes are below the streets and roads.

In other cases, some houses don’t directly connect to the sewer main. Instead, they have septic water treatment systems. Instead of going to a treatment plant, wastewater gets filtered out in the septic tank, and the effluent water gets flushed out to the soil.

Arriving at the domestic sewage treatment systems

After passing through pipes, Droppy has arrived in the water treatment system. His first stop is the bar screen. See more at Everhard

The bar screen filters the water by getting all the undissolved solids that may damage the water treatment machinery. It also aims to make the wastewater easier to treat.

The grit chambers

After Droppy visited the bar screen, the wastewater composition seemed clearer. There are no toilet papers or large solids. However, he can still see small solids that were not filtered out.

Droppy then arrives at the second step in the pre-treatment process in a domestic wastewater treatment plant, the grit chambers.

The grit chambers use a mechanical process to segregate the remaining solid waste from the wastewater.

After this process, Droppy will notice that only microscopic particles are left.

To the clarifiers

The water that’s left after filtering out the solids is called effluent water. At this stage, Droppy might still contain small solids that have a diameter of ten micrograms.

In the clarifiers, Droppy will stay there until the small solids settle at the bottom. The water filtered from the clarifiers now contains organic matter.

These organic matters will be treated using mechanical and chemical processes in the secondary treatment process.

Secondary treatment

After the clarifiers, the water treatment system introduces processes that remove chemicals and biological matter.

In the final stage, Droppy enters a disinfection process. This process may vary in water treatment plants because there are different ways to disinfect water.

After Droppy has been disinfected, he finds his way back to streams until he gets treated again for human consumption.

The end.

Treating water is important to keep adequate water supply. That’s why households should keep their sewage systems maintained. For more information about wastewater management and domestic sewage treatment systems, visit Everhard Industries at everhard.com.au for more details.
