It eventually flows directly to a lake, river, stream, wetland, or coastal water. Stormwater travels through a system of pipes and roadside ditches that make up stormwater systems. Instead, the water runs rapidly into storm drains, sewer systems, and drainage ditches and can cause: In developed areas, however, impervious surfaces such as pavement and roofs prevent precipitation from naturally soaking into the ground. Stormwater becomes a problem when it picks up debris, chemicals, dirt and other pollutants as it flows or when it causes flooding and erosion of stream banks. When stormwater is absorbed into the ground, it is filtered and ultimately replenishes aquifers or flows into streams and rivers.
