A Sustainable Approach to Stormwater
Management - from Portland BES website
Sustainable stormwater management
integrates stormwater into building and
site development. Disconnecting the flow
from the storm sewer system and
directing runoff to more natural systems
reduces the amount of runoff by allowing
water to soak into the ground, and filters
pollutants before stormwater reaches our
rivers and streams.

Rainwater Harvesting
Captured rainwater can be collected and used
to water your garden or houseplants, for
washing the car, or even for flushing toilets.
Philadelphia Green
Infiltration Systems
Focused on getting stormwater into the ground, which recharges
groundwater and provides a steady water supply to rivers and streams.
Designs include drywells, pervious (porous) pavement, infiltrating trenches,
boxes, etc.
Philadelphia Green
Bio-filtration Areas
Planters or planted basins that slow down and/or provide detention
(temporary storage) for stormwater. Plantings filter out pollutants, and
are an engine for evapo-transpiration. Bio-filtration is often combined
with infiltration.
