ABSTRACT
The provision of reliable sanitation is a prerequisite of a developed society; this is as true for the mega-cities of the twenty-first century as it was for the emerging Greek civilisations around Homer’s ‘wine dark sea’. The pressures of population and climate change present new challenges to the design engineer that may not be met merely by reference to past experience or to codified guidance. Drainage and vent system design for the highly complex structures now being developed requires that the engineer has access to proven and fundamental analysis techniques that will, at the very least, provide the same level of confidence as that ascribed to other building services simulations.
