Monday, July 20, 2020

Would you believe that you have access to a substance that's been on the earth for literally billions of years right in your kitchen?

All the water that's been on earth is still here! And it's right in your tap.

But where does tap water come from? How does it get to your kitchen sink?

Is tap water safe to drink? How does it get treated?

Using water is probably one of the most common parts of your day that you've likely never really considered. Keep reading to learn some of the background behind this commodity we all take for granted.

Where Does Tap Water Come From?

The short answer is that tap water comes from rivers, lakes, and groundwater. Your exact location may get its water from one, two, or all three of these options.

There is lots of water on earth, but only a very small percentage is freshwater and suitable to drink. In fact, only 2.5% of the water on earth is freshwater! The rest is saltwater in the oceans, which is very hard to convert to drinkable water.

There is no way to 'create' water though, and so the water that is on earth is here to stay. Sure, it can evaporate and be used by humans and so forth. But it all comes around again in the form of rain, melting ice, and flowing rivers.

So, how do we keep reusing the earth's water? By treating it.

The Water Treatment Process

Though people use water for all kinds of purposes, and it gets extremely polluted and dirtied, we are lucky in the United States to have some of the cleanest tap water anywhere.

Generally speaking, it is always safe to drink water straight from the tap. A notable exception is Flint, Michigan, which is still experiencing unsafe tap water.

Before water arrives at your tap, it goes through a sophisticated treatment process. It's a good thing it does too.

The water that we use for sewage all needs to be used again, and it comes back to the treatment facility in the form of "sludge." This sludge is a mixture of solids and liquids. Municipal water treatment facilities utilize monitors and sensors to treat and monitor levels of different contaminants.

The water treatment process includes several steps. First, chemicals are added that gather dirt and other solids together and remove them from the water. Other sediments sink to the bottom of the container.

Then, the water is filtered to remove smaller contaminants such as bacteria and dust. Finally, the water is disinfected with solutions such as chlorine.

From there, the filtered water goes on through all the underground pipes in your town to a water tower to build pressure, and then directly into your home.

The Proper Equipment
