WHAT IS STORMWATER?
 When it rains or snows, the water soaks into the ground, evaporates back into the atmosphere or runs off. This runoff, also known as storm water, has some obvious impacts such as flooding and erosion. Some less obvious, but equally important, impacts of stormwater runoff include increased pollution, reduced ground water supplies, and lower stream flows during dry spells.
Traditionally, stormwater has been seen as a nuisance to be collected and dumped into the nearest ditch or stream and disposed of. Unfortunately, such an approach neglects the reality that most of us live or work downstream of someone else. As a result, our neighbor's nuisance becomes our problem, which in turn becomes a problem for our downstream neighbors.
STORMWATER MANAGEMENT
 Stormwater management involves the control of water that runs off the surface of the land from rain or melting ice or snow. The volume, or amount of runoff and its rate of runoff, substantially increases as land development occurs. Construction of impervious surfaces, such as roofs and parking lots, and the installation of storm sewer pipes which efficiently collect and discharge runoff, prevent infiltration of rainfall into the soil.
Management of stormwater is necessary to compensate for the possible impacts of development such as flooding, erosion and sedimentation problems, concentration on flow on adjacent properties, damages to roads, bridges and other infrastructure as well as non-point source pollution washed off from impervious surfaces.
WHAT
YOU CAN DO TO HELP
Only Rain in the Drain – Never
dump anything into a storm drain, including oil,
paint, soap, debris, and leaves. Storm sewers
don't go to the sewer plant but discharge directly
into streams. You might be pouring oil into your
own drinking water!
 Auto
Care – Washing your car at home on the
driveway or street can send detergents and other
contaminants through the storm sewer system. It
is best to wash your car at a commercial car wash
where the wastewater is treated and recycled.
If you do wash your car at home, do so near a
grassy area where the water can infiltrate into
the ground. And never dump motor oil or antifreeze
into the storm drain. Dispose of these at a local
service station or approved recycling center.
Plant Native Trees and Shrubs
– Erosion of streambanks can be prevented through
the use of vegetated strips along the banks. Also
known as riparian buffers, these strips of tall
grasses, tress and flowers act to stabilize banks,
which prevents erosion and additional sediment
load in the stream.
Residential Landscaping
 Downspouts:
Direct all downspouts away from pervious surfaces
and onto lawns. Rain barrels can be used to collect
water from downspouts, making it available for
watering.
 Lawn
Care: Fertilizers and pesticides should be
used sparingly. When applied in excess, these
chemicals are washed off by rainwater and enter
the local storm sewer system. Do not sweep yard
waste and leaves into the street. These add extra
nutrients to streams.
 Rain
Gardens: A specially designed rain garden
can be planted with native vegetation to that
will provide an area for rainwater to collect
and soak into the ground. Stormwater from rooftop
drains and pavement areas can be directed to these
vegetated areas.
 Pick
Up After Your Dog – Pet waste can be
a major source of excess nutrients and bacteria
to our streams. Always properly dispose of pet
waste.

STORMWATER
IS EVERYBODY'S BUSINESS!
Who are you going to call?
 Citizens
can help report violations or problems they notice
in their local streams before they cause more
damage and pollution. Residents sometimes
may be the first to recognize "illicit"
discharges being directed into storm sewers or
flowing out of storm sewer outfall pipes into
streams. "Dry weather flows"-flows
from storm sewer outfall pipes after 72 hours
or more without rain-should be reported to your
municipality for further investigation.
 New
storm water requirements from the Pennsylvania
Department of Environmental Protection (DEP) require
that Swarthmore investigate more thoroughly
potential illicit discharges (pollutants) into
our storm sewers and streams. You can help
by promptly reporting the following events to
the authorities listed below. Here are some
of the conditions that you should report and to
whom they should be reported.
Water
pollution events can also be reported online through
the DEP web site www.dep.state.pa.us select Environmental
Complaints, then Southeast Region.
