Recent advances in remote sensing have enabled sanitary sewer system operators to deploy a large number of remote autonomous water level sensors throughout their collection systems. Real-time continuous water level measurements at dispersed key locations in a collection system provide not only direct protection from overflows, but also provide critical information that enables more efficient management of the collection system as a whole. Remote collection system assessment is possible through analysis of long-term data and water level trends, including the transitory and unscheduled effects of inflow and infiltration. Water level trends can provide early warning of constrictions caused by fats, roots, oils, and grease (FROG), enabling dispatching of cleaning crews long before serious and expensive problems occur. Performing maintenance cycles based on real-time information can result in significant savings and improved operations. In addition, capital improvements can be delayed or avoided through comprehensive monitoring. Manhole intrusions can be monitored to reduce risk of illegal dumping or manhole removal. This paper will discuss several case studies of collection systems that have deployed a large number of level and intrusion sensors in their system including Hawthorne, CA, Culver City, CA, and Mt. Crested Butte, CO and how these monitoring systems have improved collection systems operations and delayed or avoided expensive capital improvement projects.
