So instead of drinking that tap water, they spend a lot of their hard earned money on bottled water.
You might say it still costs money to drink water from the tap but really it's only a few extra pennies on the water bill.
If you're one like me who drinks tap water instead of bottled water, you can save quite a bit of money a year and also save the environment from hundreds of plastic bottles that don't get recycled.
Every state has a water treatment plant that ensures your tap water is safe to drink.
The only problem with this though is what the water picks up through the pipes on the way to your home.
You'll find that some pipes are pretty old and can add rust and bacteria to your drinking water.
To solve this problem, you use a water purifier like a Brita filter or a Pur filter.
The Brita filter comes in a pitcher where you just fill it with tap water and it's purified via the installed filter.
The Pur filter, on the other hand, can be easily installed on the your faucet itself to filter the water as it comes out of the tap.
You do, however; need to change these filters every 1 to 3 months which will cost you around $100 a year.
So what about bottled water? Maybe you bought that bottled water because of it's label telling you it's clean, spring water or water from an untouched sacred stream, but that's really not the case.
The truth is that many of these bottled water companies get their water from the same place you do, from municipal water plants.
As with anything else you buy, you should check out the label for what you're really paying for.
If the label says "purified," it probably came from the municipal water supply.
Aquafina, who is owned by Pepsi, is bottled at the Pepsi plant using purified municipal water.
Same goes with Dasani, who is bottled by Coke, but they add a few minerals and a bit of salt to make you thirsty for more.
So what are you getting with bottled water? The same stuff you could be getting from home with a purified water treatment pitcher or filter.
If you're wondering what you can carry around in your backpack instead of bottled water, stainless steel bottles are a great option.
I really like my Klean Kanteen bottle.
It's one of the very first companies to put stainless steel bottles on the market.
This family owned company even donates 1% of their profit to environmental causes.
I think they really do make the best stainless steel bottle out there.
Tapped, a new documentary about the bottled water industry, goes behind-the-scenes to show the effects of this industry on our health, climate change, pollution and our reliance on oil.
It's an eye-opening view of how bottled water has negatively impacted our environment.
So the next time you decide to drink bottled water, think about the money you spend, the impact you have on the environment and how much better off you and the earth will be by drinking from the tap.
