Water Audit—Accounting for Every DropA water audit is a means to track unbilled (also called “unaccounted for”) water throughout the system. Unbilled water is any water in the system for which you don’t receive compensation. Possible causes include flushing and/or other maintenance issues, fire suppression, leaks, illegal connections and even inaccurate meters. A basic water audit is simple to perform. Just divide the difference between total water metered and total water produced by the total water produced.
This can give you a good indication of your “unaccounted for” water and inform you if a more in-depth study is required. The EPA recommends that a water system should not have more than 10% “unaccounted for” water. A comprehensive water audit will show where the water is going and how much is being lost during each activity. By knowing this, you are able to plan for ways to recover the revenue lost from the “unaccounted for” water. A comprehensive water audit is an involved process, and training and/or assistance is often needed. Don Van Veldhuizen, Technical Training Manager at USABlueBook, is available for help in this area.
