In Honolulu, Hawaii, understanding how the Board of Water Supply and city ordinances govern water meters, billing, and conservation helps residents avoid penalties and reduce use. This guide explains how to read a water meter, common conservation measures, who enforces meter rules, and the practical steps to report leaks or billing disputes. It summarizes official sources and directs you to the agency to contact for inspections, complaints, and appeals.

How to read your water meter

Most residential meters show a series of dials or a digital register indicating cumulative gallons or cubic feet. Record the numbers left to right, ignoring moving dials for partial gallons. Note the meter serial and compare monthly readings to your bill to spot leaks or billing errors. For official instructions and diagrams, see the Board of Water Supply guidance[1].

Check your meter before and after a two-hour period with no water use to spot leaks.

Conservation rules and practical measures

Honolulu promotes water conservation through voluntary programs, rebates, and customer guidance. Common measures include installing low-flow fixtures, fixing leaks promptly, and adjusting irrigation schedules. For program details, check the Board of Water Supply conservation pages in Resources.

Small leaks can waste hundreds of gallons a month; early repair saves money and water.

Billing, meter reading and disputes

Customers can compare their own meter logs to billed usage and contact the Board of Water Supply for suspected errors or to request a meter test. Keep written notes of readings and dates and submit a formal complaint to the utility customer service contact[2].
