What factors are storm drainage systems designed to accommodate?

Storm drainage systems are specifically designed to handle rainfall intensities and area sizes. This is critical because these systems need to effectively manage the volume of water that can accumulate during a rainstorm, which varies greatly based on the intensity of the rainfall and the size of the area being drained.

When designing storm drainage systems, engineers consider local climatology to understand the frequency and intensity of storms that a given area may experience. This data helps in calculating the necessary capacity of the drainage system to prevent flooding and ensure proper water flow during and after storm events. Thus, storm drainage systems must be tailored to the specific conditions of the location in question.

In contrast, factors like heavy industrial waste, grass and vegetation areas, or domestic water usage patterns, while relevant to different aspects of plumbing and environmental design, do not directly pertain to the primary purpose of storm drainage systems. These elements influence other areas of infrastructure or environmental management but do not dictate the capacity required for stormwater management.
