New Hampshire Department of Environmental Services, Winnipesaukee River Basin Flow Monitoring Program
The Winnipesaukee River Basin Program (WRBP) is a state-owned system in the Lakes Region of the state that includes 14 wastewater pumping stations, approximately 55 miles of large diameter interceptor sewers and a wastewater treatment facility (WWTF) in Franklin, NH treating an average of 5.5 million gallons of wastewater per day. EST performed flow monitoring at 12 permanent locations and 4 rain gauge sites throughout the collection system. This program was part of WRBP’s effort to update flow-based cost recovery plans for operations, target the removal of inflow/infiltration, and assist with capital project planning and wastewater flow management. EST’s flow monitoring installations were equipped with wireless telemetry to facilitate real time data acquisition by means of a password protected website. Services included: installation, maintenance, and calibration of flowmeters, data hosting, and report generation. All work was performed in accordance with EST’s corporate health & safety requirements and applicable NHDOT and OSHA standards.
For over fifteen years, EST was contracted by the Narragansett Bay Commission (NBC) to install, calibrate, replace, and maintain continuous flow monitoring and rain gauge equipment throughout the NBC service area.
