Real-Time Wireless Monitoring of Key Customer Sewer Flow Meters Delivers Return on Investment

The City of Joliet provides sanitary sewer collection and treatment for 150,000 residents. Additionally, the City accepts flow from commercial customers and five (5) satellite sewer districts, resulting in a total equivalent population served of approximately 180,000. Satellite districts pay the City monthly based on actual measured sewer flow accepted into the Joliet collection system; therefore, inflow and infiltration are a significant concern to the districts. Ultrasonic flow meters, owned and maintained by the satellite districts, are utilized to measure total flow volume for the billing period. The City has realized significant cost savings and enhanced revenue through automated, real-time, wireless monitoring of the district sewer meters. Customer access to "real-time" flow meter readings has confirmed billing accuracy and eliminated delays in bill payment. Additional benefits include reduced cost for meter reading and a wealth of data to guide future system rehabilitation to reduce inflow and infiltration.
