You’ve probably heard it before. New York City tap water is the "champagne of tap waters." People swear it’s the secret reason the bagels are chewy and the pizza crust is perfect. But then you see a viral video of a century-old pipe bursting in Times Square, or you read a scary headline about lead levels in older school buildings, and you start to wonder. Can you drink the tap water in New York City without a second thought, or are you better off lugging cases of Ozarka up your walk-up?
Honestly, the answer is a resounding yes, but with a few very specific, very "New York" asterisks.
New York’s water system is a marvel of 19th-century engineering that somehow still functions in a 21st-century world. It doesn’t come from the Hudson River (thank god). Instead, about 90% of it travels from the Catskill and Delaware watersheds. Some of these reservoirs are over 100 miles away. Because the land around these lakes is so strictly protected, the water is naturally incredibly clean. In fact, NYC water is so high-quality that it is one of only five large city systems in the U.S. that doesn't require a massive filtration plant for its mountain-sourced supply. The EPA gave them a "filtration avoidance" waiver decades ago, and they’ve fought like hell to keep it.
The Journey From the Catskills to Your Kitchen
It’s a long trip. Gravity does most of the work. No, seriously—the water flows downhill through massive aqueducts, some deep enough to fit a subway train. By the time it hits your faucet, it has been treated with chlorine to kill bugs, fluoride for your teeth, and food-grade phosphoric acid to coat the pipes so lead doesn't leach out.
They also use UV light. At the Catskill-Delaware Ultraviolet Disinfection Facility—which is the largest of its kind in the world—the water is blasted with rays to zap Cryptosporidium and Giardia. It’s high-tech stuff for a system that basically relies on rain falling in the woods upstate.
But here is the catch. The city is responsible for the water until it hits the street-side of your building. Once it enters your property? That’s on the landlord.
Can You Drink the Tap Water in New York City if Your Building is Ancient?

If you live in a beautiful pre-war brownstone in Bed-Stuy or a classic Upper West Side apartment, your building might have lead service lines or internal lead plumbing. While the city's water is lead-free when it leaves the reservoir, it can pick up lead as it sits in old pipes overnight.
It's a weird paradox. You have world-class water entering a building with 100-year-old "veins."
Don't panic, though. You can actually check this. The NYC Department of Environmental Protection (DEP) offers a free lead testing kit to any resident. You just fill up some bottles, mail them back, and they send you the results. It’s one of the best-kept secrets in the city. If you’re worried, just run the water for 30 seconds until it gets cold. That flushes out the "sitting" water. Simple.
Why Does It Taste Better Than Other Cities?
It's "soft."
Water hardness is measured by the amount of calcium and magnesium it picks up from the ground. Because NYC water sits in reservoirs over metamorphic rock (which doesn't dissolve easily) rather than limestone, it stays very soft.
This matters for two reasons:

- It doesn't leave that crusty white scale on your showerhead.
- It interacts with yeast differently.

Common Myths About NYC Tap Water
Some people think the water is full of "shrimp." This is... partially true?
There are tiny, microscopic crustaceans called copepods in the water. They aren't harmful; they actually help eat mosquito larvae in the reservoirs. They are too small to see with the naked eye, but because they are technically "shellfish," some extremely observant Jewish residents choose to use filters to ensure the water remains strictly Kosher. For everyone else, it’s just a bit of extra, invisible protein.
Then there’s the "cloudy" water thing. You turn on the tap, and it looks like milk. You wait thirty seconds, and it clears up from the bottom. That’s just air. High pressure in the pipes forces tiny bubbles into the water. It’s totally harmless.
The Environmental Cost of the Alternative
If you're still reached for a plastic bottle, consider this: NYC tap water costs about one penny for every two or three gallons. A bottle of Evian costs three dollars and is often just filtered tap water from somewhere else.
Plus, the city is constantly testing. We're talking 600,000 tests a year. They have robotic buoys in the reservoirs and scientists in labs checking for everything from bacteria to radioactive isotopes. It’s one of the most monitored substances on the planet.

What You Should Actually Do
If you’re new to the city or just skeptical, here is the move. Stop buying bottled water. It’s a scam and a waste of plastic.
First, go to the NYC DEP website and order that free lead test kit. It costs nothing. Second, get a basic carbon filter—like a Brita or a Pur—if you don't like the slight taste of chlorine. The chlorine is necessary to keep the water safe as it travels through miles of pipe, but it can smell a bit like a swimming pool on a hot day. A filter fixes that instantly.
If you’re in an old building, be smart. Never use water from the hot tap for cooking or making baby formula. Hot water dissolves metals like lead much faster than cold water. Always start with cold and heat it up on the stove.
Actionable Steps for New Yorkers
- Test your water: Call 311 or visit the DEP website to request your free Lead in Training Kit. It’s the only way to know what’s happening in your specific apartment.
- Flush the pipes: If you’ve been away for a weekend or it’s first thing in the morning, run the tap until the water feels noticeably colder.
- Check the map: The NYC Open Data portal has a map of where lead service lines are suspected to be. You can look up your specific address.
- Maintain your tank: If you live in a high-rise with a wooden water tank on the roof, ask your building manager when it was last cleaned. These tanks are iconic, but they need to be inspected annually to keep out sediment and, well, pigeons.
- Ditch the plastic: Buy a high-quality stainless steel bottle. The city even has "portable manifolds" (giant fountains) at street fairs in the summer so you can refill for free.
New York City water isn't just "safe"—it's a luxury that most of the world would kill for. As long as your building’s plumbing isn't a relic from the Victorian era, you should feel perfectly fine drinking straight from the sink. It’s cheap, it’s clean, and it makes a damn good cup of coffee.
Next Steps:
Check your building's "Water Quality Report" which is released annually by the city. It provides the exact parts-per-billion for every chemical and mineral found in the system during the previous year. If you find your building has high lead levels, your landlord is legally required to address the service line, but in the meantime, a filter certified for lead removal (look for NSF/ANSI Standard 53) is your best friend.
