How Much Water Does a Leaking Faucet Waste? Those Drips Add Up

While a dripping faucet in your sink or tub may initially be a little annoying, it can quickly become forgotten—lost in your list of “I’ll get to that someday.” Those little drips can add up, though, and you might be surprised by how much water a leaking faucet can waste.

Running the Numbers

First, did you know the average home in the U.S. uses about 300 gallons of water each day, which equates to well over 100,000 gallons annually?

We use water for everything from flushing our toilets to showering and washing our dishes and clothes—not to mention the water we use outside for our plants and grass.

When it comes to drips, the USGS has a rough calculation (because there’s no scientific definition as to how much volume is in a water drip) of 15,140 drips to a gallon.

Using that number, the USGS created an online calculator that will give you an idea of how many gallons you might be losing to a leaky faucet each day and then annually. Here are some of the results we got using the calculator:

1 home with 1 leaky faucet leaking 10 drips a minute

  • 1 gallon of water lost in a day
  • 347 gallons lost in a year

1 home with 1 leaky faucet leaking 120 drips a minute

  • 11 gallons of water lost in a day
  • 4,165 gallons lost in a year

1 million homes with 1 leaky faucet leaking 10 drips a minute

  • 951,122 gallons of water lost in a day
  • 347,159,841 gallons lost in a year

That’s a lot of water, right? And while a leaky faucet might only raise your water bill by a fraction (typically, a toilet leak is what will start costing you), it’s interesting to see just how much drops of water can add up over time.

How Do I Get My Leaky Faucet Fixed?

A leaky faucet may only require a simple fix that can be a DIY project if you’re handy. For example, you might have gaskets, o-rings, or washers that need to be replaced or are loose.
