Sanitary Sewer Flow Monitoring and Data Analytics

Flow monitoring is an essential procedure to collect data for evaluating and characterizing wet-weather and dry-weather flow conditions in sanitary sewer collection systems. Real time use of the data for supporting operational decision-making/optimization and in-time maintenance activities has been a growing trend. Over the past three decades, industry practices have evolved in designing flow/rainfall monitoring programs with progressively more effective data analytics that support many business needs. The primary objective of this fact sheet is to summarize industry-wide observations on basics of flow monitoring strategies; data management and analytics; and notable references for developing deeper knowledge.
