Abstract : The paper first reviews past research on the hydraulics of drainage systems and points to the need for a general design method. Drawing on past work and the results of recent laboratory measurements, a method for calculating suctions in stacks is put forward and measured and predicted seal losses are compared. Reasonable agreement is shown. The paper uses this work as a basis for a method for the sizing of drainage and vent stacks in multi-storey buildings. Examples of stack and vent sizes calculated by the method are shown and compared to findings from tests on existing buildings. Some further development of the method is possible, and further laboratory data on some aspects are still needed. The final outcome should be a design procedure of general application. (Author)
