The PUD conducted testing of 74 randomly selected water meters in the Carson and Underwood water systems to evaluate the existing meter accuracy. All customers that were part of the meter testing project were notified prior to the meter change. The old water meter was sent to a lab for bench testing and replaced with a new electromagnetic flow meter. The new water meters are compatible with an advanced metering system; however, no radio module was installed in the meter to allow for radio frequency (RF) communication. The weighted average accuracy of the old meters, based on measurements at minimum flow, intermediate flow, and maximum flow, found that the meters underreport water usage by 9.1%.
