Plumbing, by the Numbers

It’s easy to take plumbing for granted. Don’t feel guilty–we do it too! To celebrate World Plumbing Day, we decided to take a look at our profession by the numbers. People commonly underestimate the impact plumbing has on us day-to-day until they see it represented in pure stats. Calculating the statistics behind our profession is a humbling experience, and one that inspires us to work even harder on your behalf.

Here are a few of the most mind-blowing water usage and plumbing stats, starting in your home and working up to around the whole world.


In the Home

  • The average US family of four uses up to 400 gallons of water a day.
  • The average US individual uses around 127,400 gallons of water a year.
  • Flushing a modern toilet requires around 1.6 gallons per flush. Older toilets can require between 3.5 up to 7 gallons per flush.
  • A running toilet can waste up to 200 gallons of water per day.
  • Running showers consume 2.5 gallons of water per minute of use.
  • Sinks use 2 gallons of water for every minute they’re left running.
  • Turning off the tap while brushing your teeth can save 200 gallons of water a month!
  • 10% of US homes have small plumbing leaks which waste 90 gallons of water or more a day
  • Having a professional locate and repair small plumbing leaks can save more than 10 gallons of water per day.
  • The daily price of water in the US depends on where you live; a Dallas household that uses 40 gallons of water a day would pay $43.88 on a 30-day month, according to Dallas’ residential water charges calculator.


On the Job
