Pima County RWRD needed more reliable, accurately time-stamped power data from the distribution system at its Tres Rios Water Reclamation Facility. CEI delivered a power-quality monitoring system design upgrade, performing site visits and preparing design drawings and specifications while coordinating between the County and the contractor. The upgrade replaced aging power meters with current units for accurate time-stamping of metering and event data and strengthened the plant-network server system, giving the County better data collection and a more reliable view of its power distribution.
