Detect-A-Leak Week
The Detect-A-Leak Week campaign encourages residents and businesses to find and fix common household leaks that often go unnoticed, wasting our precious water supply and increasing utility bills. According to the Environmental Protection Agency, household leaks can waste nearly 900 billion gallons of water a year -- equal to the annual water use of nearly 11 million homes.
Each year, the Board of Water Supply (BWS) partners with other agencies and businesses to help raise awareness. For the 2026 Detect-A-Leak Week, join the Board of Water Supply (BWS) and City Mill this year as they host two free, family-friendly events where residents can learn how to detect and fix common leaks, get practical water-saving tips, pick up free toilet leak detection dye tablets, play games, and win prizes.
