Join AWE and WaterSense Partners from across North America for Fix a Leak Week 2025! Household leaks can waste nearly 1 trillion gallons of water annually nationwide, so each year, we hunt down the drips during Fix a Leak Week. Mark your calendars for Fix a Leak Week, March 17 through 23, 2025—but remember that you can find and fix leaks inside and outside your home to save valuable water and money all year long.
