While single-purpose gray stormwater infrastructure—conventional piped drainage and water treatment systems—is designed to move urban stormwater away from the built environment, green infrastructure reduces and treats stormwater at its source while delivering environmental, social, and economic benefits.

Examples:

More information about specific types of green infrastructure can be found in an Introduction to Green Infrastructure including green roofs, permeable pavement, and rainwater catchment systems.

Benefits:

Collecting and using rainwater water reduces your workplace's water consumption, reduces pressure on the sewer system, and reduces water purchasing costs.
