Stormwater harvesting and management/Stormwater collection surface

The type of collection surface that rain impacts and flows over is how stormwater is differentiated from rainwater. Often, these surfaces are more difficult to achieve proper first-flush pollution control measures on and the wide range of surfaces that the water can flow over, means that stormwater may contain much greater amount of pollution than rainwater.

Collection Surface Materials

Permeable Surfaces

Compacted Ground

The exact composition that compacted surfaces are made depends on the geography and geological features of the local landscape.
