Drink Like a Local: Celebrate National Hydration Day

June 23 is National Hydration Day — a perfect time to pause, refill your glass, and remember just how important water is to your health and your daily life.

From staying energized to keeping your body functioning at its best, hydration plays a bigger role than many people realize. In fact, the human body is about 60% water, with the brain made up of 80–85% water and the heart around 75–85% water. Even your bones and teeth rely on water to stay strong.

Why Hydration Matters

Water supports nearly every system in your body. It helps regulate temperature, supports circulation, and keeps your body moving and thinking clearly.

And hydration habits don’t just affect how you feel — they can impact your overall health. That’s why something as simple as choosing water throughout the day can make a meaningful difference.

Hydration Starts with High-Quality, Reliable Water

Here in Louisville, staying hydrated is easy thanks to a trusted and local source.

Louisville Water has been delivering safe, high-quality drinking water since 1860, serving nearly one million people every day. Our water comes from the Ohio River, a 981-mile waterway that is continuously monitored to ensure it remains safe and reliable from source to tap.

In fact, Louisville’s water is so exceptional, we gave it a name — Louisville Pure Tap® — and it’s been recognized as the “Best Tasting Tap Water in America” in national competitions.

Good for You — and the Planet

Choosing tap water doesn’t just support your health — it supports the environment, too.

Every second, about 1,500 plastic water bottles are used, yet only 10% are successfully recycled. And a single plastic bottle can take more than 450 years to break down.

By choosing Louisville Pure Tap®, you’re making a simple switch that reduces waste, saves money, and supports a more sustainable future.

Water Is Everywhere — And It Matters More Than You Think

Water plays a role in far more than what’s in your glass. It’s part of the food we eat and the world around us:

A tomato is 95% water, and apples are about 86% water
It takes about 33 gallons of water to grow a single apple
Producing a chocolate bar requires about 450 gallons of water

Even in nature, water continues to amaze — ice floats because it’s less dense than liquid water, and the Ohio River supports 160 species of fish, highlighting the importance of protecting our water sources.

Simple Ways to Stay Hydrated

Making hydration part of your routine doesn’t have to be complicated:

Carry a reusable water bottle and refill throughout the day. Pure Tap pro tip: If you don’t have one, you can request one by filling out this form.
Drink water before you feel thirsty.
Choose water instead of sugary beverages.
Increase your intake when you’re active or spending time in the heat.

Make It a Habit

This National Hydration Day, take a moment to reset your routine. Refill your bottle, reach for the tap, and make hydration part of your everyday life.

Because when you drink Louisville Pure Tap®, you’re choosing water that’s local, sustainable, and made for you.
