PCWA will install leak detection dataloggers (flow monitoring devices) on selected treated water transmission mains within areas of aging pipelines at various locations in the Colfax area within PCWA Zone No. 3. The purpose of this project is to monitor pipelines in order to pinpoint leaks for repair and initiate repair of those leaks utilizing best management practices. Where possible, existing valves will be used as monitoring locations, but a total of 50 additional sites could be needed (25 in alta and 25 in Colfax). These additional sites will be excavated using a vacuum trailer and a piece of plastic pipe will be installed with a valve cap.
