WET WEATHER AUTOMATED METERING AND EVALUATION FOR I&I REMOVAL

The City of Huntsville, Alabama's Water Pollution Control Department has taken a proactive approach to Management, Operations, and Maintenance (MOM) of their collection system. One aspect of the approach was to create an automated permanent flow monitoring program. This approach to flow monitoring allows WPC to manage the flow monitoring network remotely through a hard wired system to reduce flow monitoring and reporting costs, improve collection system performance through timely identification of blockages and other conditions affecting the system's performance, collect extensive data related to system performance over time, and program investigations and other Inflow and Infiltration (I&I) reduction activities in a fiscally responsible manner. WPC built this system using only off the shelf software and has ultimately realized a substantial cost reduction for flow monitoring when compared to “blind” permanent or temporary metering.
