In eight chapters, this book presents design guidelines and hydraulic calculation methods of vacuum sewage systems. After a short history of vacuum sewerage, the book covers the theoretical basis of multiphase flows, empirical approaches for the dimensioning of vacuum pipes, and conceptual, mechanistic and numerical two-phase flow models.
