Municipal Stormwater

Stormwater and our Environment

Stormwater is the water from snow and rain that collects on the ground. The ground is broadly divided into two types:

• Pervious: These areas absorb water into the ground, generally at or near where it falls. Think natural areas, wetlands, grass, and sand.
• Impervious: These areas stop water from being absorbed into the ground. Think roads, parking lots, and buildings. 

Stormwater that falls on impervious areas is usually collected and moved away from things like buildings or roads. This collected water, called runoff, is moved by catch basins, pipes, and swales.  The runoff ultimately reaches our streams, rivers, wetlands, and coast. As runoff moves over surfaces, it can pick up pollutants, like chemicals and litter, and carry them to our waters.  Pollution also happens when people put contaminated water or pollutants on the ground or into catch basins.
