What happens to access rain water that go in drains?

Rainwater that enters drains typically leads to stormwater drainage systems, which direct the water away from urban areas to prevent flooding. Depending on local infrastructure, this water may flow into nearby rivers, lakes, or oceans, often without treatment, potentially carrying pollutants. In some areas, rainwater is captured and redirected for reuse, but in many cases, it simply contributes to surface runoff and can lead to water quality issues in natural water bodies. Proper management and green infrastructure can help mitigate these effects.
