Detect-A-Leak Week: Do your part to conserve water starting March 16

Free toilet leak detection dye tablets available

Sponsored by Board of Water Supply

The Honolulu Board of Water Supply (BWS), in partnership with Hardware Hawaii, is launching Detect-A-Leak Week from March 16-22, 2020, to encourage all Oahu residents to check for property leaks. Water resources in Hawaii are limited, so it’s important not to waste a drop. If we work together to save enough water now, we’ll have what we need for years to come.

A leak is “the sneaky water waster,” since customers pay for water they don’t use. According to the United States Environmental Protection Agency, the average American home can waste more than 10,000 gallons of water every year from running toilets, dripping faucets, and other household leaks. That’s why it’s important for all water users to check their plumbing fixtures for leaks.

During Detect-A-Leak Week, all Oahu water users are asked to check for leaks in toilets, plumbing fixtures, irrigation systems, and other water-using equipment. To help with this effort, free toilet leak detection dye tablets are available at all Satellite City Halls, Hardware Hawaii stores, and the BWS lobby at 630 South Beretania Street.

How to Detect Leaks on Your Property:
1) Turn off all your water faucets, pipes, and other water-using fixtures to make sure no water is running.
2) Locate your water meter cover, which should be in or near the sidewalk area fronting your building or home.
3) Open the meter box cover, flip up the white lid on the meter, and check to see if the dial is moving. If it is, you have a leak! Replace the cover and rotate it to secure it.

Those who want to conduct their own leak inspection can visit the BWS website or on Facebook, Instagram and Twitter for tips on how to check for leaks. More information about leaks and conservation is also available by calling the BWS at 748-5041 or emailing
