Lake County, Illinois – Lake County Illinois wanted to figure out how and to what degree excess clear water was entering its wastewater collection system during rain events. To determine sanitary flows, the County enlisted RJN to conduct long-term flow monitoring in its Southeast Facility Planning Area (FPA) and Northwest FPA. The results are being used to develop expanded study programs to identify removable I/I sources.
Laurel, Maryland – WSSC (Washington Suburban Sanitary Commission) gathers collection system performance data using a network of 210 flow meters and 18 rain gauges. A critical aspect of RJN’s selection for the program was the ability to provide access to flow data as it is being collected and integrated flow level alarming and alerting features that provide notification of high flow conditions in real time.
Austin, Texas – The City of Austin Water Utility sought RJN’s help with long-term flow monitoring services to collect data for the City’s inflow and infiltration programs, hydraulic modeling, and precautionary measures with regards to surcharging and wastewater overflows. The program involves maintaining and monitoring a network of permanent meters as well as initiating temporary metering to collect data for specific applications.
Cincinnati, Ohio – Recently, the Metropolitan Sewer District of Greater Cincinnati (MSDGC) transitioned to a remote monitoring system that uses wireless telemetry for their flow metering network. MSDGC selected RJN Group, Inc. to assist with the transition to wireless flow data collection activities and the development of ongoing data analysis and management efforts. RJN provides services on an "as-needed” basis to meet the needs of ongoing MSDGC initiatives.
