How do stormwater systems differ from wastewater systems?

The correct answer highlights a fundamental distinction between stormwater systems and wastewater systems. Stormwater systems are specifically designed to manage rainwater and surface runoff, collected from precipitation events. This involves transporting water away from impervious surfaces like roads and parking lots, helping to prevent flooding and erosion.

On the other hand, wastewater systems are focused on treating and disposing of human-generated waste, which includes sewage from residential, commercial, and industrial sources. This difference in purpose underscores how each system addresses unique aspects of water management—stormwater systems primarily deal with natural water cycles, whereas wastewater systems handle contaminants from human activities.

The distinction is crucial for understanding the infrastructure and regulatory requirements for each system, as they operate under different principles and serve varying environmental and health objectives.
