NRW Reduction through fire service auditing

Water Loss/Non-Revenue Water
Description

In an increased effort to control NRW KAWC created a work group called the Nonrevenue water Subcommittee which was part of a larger group known as the task force. This smaller group was designed to take deeper dives into more complex subjects concerning NRW. One such subject that came out of the smaller group was that of usage on fire services and how that relates to NRW. So we knew that there was a lot of unaccounted for water being lost on fire service just because the 5/8" meters could not register all of the flow on larger fire mains. We began looking for a way to quantify this water loss with the least disruption to the customer as possible. We came up with using a clamp-on ultrasonic meter and then began reviewing many styles and brands of these meters. We settled on one particular brand and bought four units. Our first day in the field we were able to quantify two large leaks on fire mains totaling over 100,000 gallons per day. Since then we have performed audits at dozens of fire services and we have found more than 5,000,000 gallons per month. This has turned out to be a very helpful tool for dealing with customers. The customer can see exactly what the loss is and not just what the detector check meter reads.
