This multidisciplinary book provides insights into the applications of the Internet of Things (IoT) to combined sewer overflows (CSO) and stormwater management (SWM) systems. It explores technical challenges and presents recent results to improve sewer and drainage system management using wireless underground communications and sensing in IoT. The book addresses both existing sensing network technologies and those currently in development in three major areas of CSO: combined sewer overflow management, subsurface sensing, and antennas in the layered medium. It explores new applications of IoT in sewer systems to improve public health, foster economic growth, and enhance environmental quality and responsibility for the community. Internet of Things in Smart Sewer and Drainage Systems: Theory and Applications  will be a valuable reference for graduate students and academic researchers, as well as a hands-on guide for wastewater technicians, sanitary engineers, environmental specialists, and related industry practitioners.
