Abstract: Drainage demand estimation for an effective and healthy drainage stack design is examined in this study. Empirical expressions that incorporate building occupant load, simultaneous usage patterns and discharge flow attenuation along a horizontal pipe into the probable drainage load determination for a stack serving a number of domestic washrooms as installed in typical high-rise buildings in Hong Kong are proposed. Patterns of probable drainage demand and probable discharge flow in the stack are determined via Bayesian analysis and Monte Carlo simulations, respectively. The study outcome enables more effective sizing of a drainage stack for some residential buildings in a dense urban environment. Practical application: Providing a mathematical model for drainage load calculations, this study is a useful tool to aid drainage stack sizing for some high-rise residential buildings.
