What does stormwater management aim to control?

Stormwater management primarily aims to control runoff from rainfall. When precipitation occurs, especially in urban areas, surfaces such as roads, roofs, and pavements can prevent water from soaking into the ground. Instead, this water runs off into storm drains and waterways, which can lead to various issues including flooding, erosion, and water quality degradation. Effective stormwater management practices are designed to mitigate these impacts by implementing systems such as detention basins, green roofs, permeable pavements, and other techniques that allow for better absorption and management of rainwater. This helps in preventing pollution, managing flood risks, and replenishing local aquifers where possible.
