S. 142 Wastewater Metering System Equipment ReplacementProject Purpose and Benefits Extends current asset life Improves system operability and reliability.To improve the accuracy of meter data used to determine wholesale wastewater charges. This will be accomplishedby replacing the existing wastewater metering system, including hardware and software utilizing the latest availabletechnology. This technology will reduce confined space entries, making the metering system safer and less costly tomaintain. This project will be coordinated with and support SCADA implementation for the wastewater system.Meter replacement was completed in FY06.Project History and BackgroundInstallation of MWRA’s initial wastewater metering system began in 1989 and was completed in 1994. Individualmeters in 43 customer communities receive routine maintenance on a continuous basis. This initial system wasreplaced in 2004-2005. Lessons learned with the initial metering system was that the life expectancy of wastewatermeters is approximately 7-10 years and that timely replacement of meters can be scheduled to avoid whole scalereplacement. Our current system is approaching it’s 6 th year. Plans will be developed to evaluate new wastewatermetering technology for our 3 rd generation of meters. Meter replacement will be phased in rather than entire systemreplacement. Certain key meters will be supplied electric power instead of battery resulting in more civil, electricaland construction costs.ScopeSub-phasePlanningEquipmentPurchase/InstallationPermanent SiteImprovementsDesign and ConstrWastewater MeteringAssetProtection/EquipmentPurchaseScopeDevelopment of a long-term plan to upgrade or replace the existing wastewater meteringsystem (technology, hardware, software, telemetry).Purchase and installation of equipment.Supply of power and enhanced wireless communications to approximately half of the218 permanent wastewater metering sites.
