By Ellen Rodger

What lies beneath your city or town? Underground City Systems uses cutaway illustrations to explore the world's great sewer and water systems. Readers will be amazed by such startling facts as the "fatberg" causing problems in London, England's sewer system, and toilet-swimming sewer rats that plague all sewage systems. Readers will also learn about other underground services and systems, including heating and cooling, power and cable, as well as underground farming.
