Around the Water Cooler: Is Your Toilet Leaking?

By Sarah Blau

WHAT IS THAT NOISE?!? When I first moved into my apartment, I noticed a strange and persistent noise coming from the bathroom. On an exploratory mission, I fumbled around the various fixtures and plumbing only to discover that my toilet was leaking! Luckily, I caught the leak early and got it fixed.

Surprisingly, a leak like mine could waste up to 200 gallons of water a day! My water bill alone would have given me palpitations, let alone the knowledge that I was so carelessly wasting one of our very precious resources.

It's Fix a Leak Week!

Stories like mine are the reason this week is “Fix a Leak Week,” sponsored by WaterSense, an EPA Partnership Program. EPA and others are working to raise awareness about water leaks, to provide tips and information to water users, and ultimately, to reduce the waste of this life-sustaining resource. The WaterSense website provides some shocking statistics about the amount of water actually wasted each year as well as how you yourself can check for and fix household leaks.

Water lost to leaky plumbing is not isolated to inside homes and buildings. The aging water infrastructure of our country is awash with leakage problems as well. In fact, just this past Monday a water main break near Washington DC, spewed an estimated 60 million gallons, depleting local water storage tanks and initiating water conservation efforts for the neighboring communities!

EPA scientists are addressing this leakage problem this week and year-round. Researchers are working on new tools and methods to identify and monitor the weak points of aging water distribution systems. For example, researchers are looking at ways to assess water infrastructure for leaks without disrupting water supply for consumers (i.e. avoiding water shut-offs or pipe excavations). Other research is focused on preventing leaks from occurring, specifically, by examining the relationship between water chemistry and plumbing life expectancy.

As for me, I see Fix a Leak Week as a good reminder that our water resources are limited and we should work to conserve what we’ve got. Since my leak’s been fixed already, I’ll instead resolve to take shorter showers, turn off the tap while brushing my teeth, and work to spread the word by blogging (check mark that one!).
