IS STORMWATER MANAGEMENT?
Municipality of Monroeville encompasses roughly
19.7 square miles of the earth’s surface.
Over the course of an average year 36 inches of
precipitation falls on Monroeville which amounts
to roughly 12.3 billion gallons of water. In a suburban
setting like Monroeville approximately 60% of this
water is not absorbed by the ground and becomes
roughly 7.4 billion gallons of stormwater runoff
which flows untreated
into storm sewers and streams.
runoff has several negative consequences:
1. Runoff from areas like maintained lawns, roads,
parking lots, driveways, and construction sites
carry pollutants such as oil, gasoline, transmission
fluid, road salt, sediment, etc. which pollute the
streams and rivers harming the aquatic ecosystem
and polluting the waters we use for recreation and
2. Runoff, especially from roofs and paved areas,
has higher temperatures which harms aquatic ecosystems
in streams and rivers by raising water temperature
and reducing oxygen levels in the water.
3. Higher runoff rates make the streams and rivers
flow deeper and faster eroding the stream banks
which is harmful to the aquatic ecosystems and often
causing roads and other infrastructure to be undermined
4. Higher runoff rates result in downstream flooding
which damages public and private properties.
5. Water that runs off is not absorbed into the
ground, which in turn decreases groundwater levels
needed to provide well water to some people and
to maintain adequate stream flows in drier months.
6. Increased runoff necessitates more stormwater
infrastructure (pipes, inlets, manholes, detention
facilities) which costs taxpayer money to build
order to address all these issues the Municipality
has enacted a stormwater management program. The
program provides for the operation of a storm sewer
system and rules to address stormwater runoff from
lands in the Municipality. This program is regulated
by the Federal Clean Water Act under a system called
the National Pollutant Discharge Elimination System
(NPDES) Municipal Separate Storm Sewer System (MS4)
permit, commonly referred to as an MS4 permit. Under
the program the Municipality is required to obtain
an MS4 permit to discharge stormwater, and the permit
stipulates many activities that the Municipality
must conduct in order to stay in compliance.
purpose of this website is to educate the public
while satisfying some of the permit requirements.
DOES MONROEVILLE MANAGE STORMWATER?
manages stormwater in the following ways:
1. Monroeville operates and maintains the following
a. 3,693 storm sewer pipes
constituting roughly 68 miles of pipe
b. 3,047 storm sewer inlets
also known as catch basins
c. 338 storm sewer manholes
d. 707 storm sewer headwalls
e. 34 stormwater detention
f. The estimated value of
this infrastructure is $36 million.
Monroeville utilizes a state-of-the-art street sweeper
to clean the roads twice a year, in spring and fall,
which removes sediment and other pollutants which
might otherwise wash into the storm sewer system
and into streams.
3. Monroeville periodically inspects the water quality
of 523 storm sewer outfalls to monitor them for
4. Monroeville requires construction projects to
install stormwater detention facilities and stormwater
Best Management Practices (BMP’s) which temporarily
store runoff during rain events and clean and cool
the runoff to combat some of the negative aspects
5. Monroeville annually conducts public involvement
and participation by hosting the Jack Sedlak Clean-up
day in April. This event removes hundreds of bags
of litter and refuse from roadsides and streambanks
which might otherwise end up the streams and creeks.
The Municipality promotes and advertises this event,
provides gloves, bags, vests, crews to collect the
bags and transport them to the landfill, and hosts
a picnic afterwards for the volunteers complete
with food and prizes.
6. Monroeville maintains an Adopt-a-road/ stream
program where families or community groups can adopt
a portion of road or stream to keep clean of litter
and refuse that might otherwise pollute creeks and
7. Monroeville utilizes proper snow removal techniques
including a state-of-the-art brine maker to minimize
the amount of road salt applied to the roadways
which ultimately washes into streams.
8. The Municipality conducts leaf collection in
the fall which removes tons of leaf litter from
potentially entering the runoff stream and in the
process creates beneficial leaf mulch for use throughout
9. The Municipality conducts public education and
outreach to inform residents and businesses about
stormwater management via this website, TV-15, newspaper,
and other methods.
WHAT CAN YOU DO TO HELP?
Be Part of the Problem!
dump anything other than water into storm sewer
grates or onto roads!
• ONLY RAIN IN THE DRAIN!
The water that enters the storm sewer grates does
not get treated! This water flows
directly into creeks and streams. If you dump oil,
antifreeze, paint, paint thinner, pesticides, fertilizer,
chlorinated pool water, etc. into the storm sewer
or onto the road it will end up poisoning the creeks
put pet waste in the storm sewer grates!
We have ongoing problems with people putting pet
waste into storm grates. The bacteria in the pet
waste pollutes the creeks and streams. The plastic
bags pet owners use to collect and dispose of the
waste clogs the storm sewers causing flooding and
requiring expensive repairs
• Pet waste should be placed in the garbage,
flushed in the toilet, or buried in the yard.
• See this website
pollution by improperly draining your pool (or hot
Wait a few days after you last add chlorine before
you drain the pool, the chlorine will dissipate
over a fewdays. Check the chlorine level before
you drain to make sure it is gone.
• Add a dechlorinator
like sodium thiosulfate to the pool to eliminate
the chlorine, this is available at pool stores.
• Check the pH of the water before draining.
The pH should be close to 7, which is neutral. If
the pH differs, adjust the chemicals and retest
until the pH is acceptable. Use your pool water
testing kit to check the pH.
• Don’t just drain onto a driveway or
street. Ideally let the water drain across lawn
or other vegetated areas for as long a distance
as possible before it gets to the road or storm
sewer. This filters the water and allows some of
it to soak into the ground. If you have dechlorinated
and checked the pH your lawn will love this deep
Don’t dirty the
water by washing your car!
Obviously car wash water includes nasty pollutants
like soap, road salt, oil, dirt, antifreeze, etc.
which you would not want to flow into creeks and
streams where it can kill fish, insects, frogs and
other aquatic life.
• Ideally wash your car at a commercial car
wash. The dirty water at car washes goes to a treatment
plant where it is properly treated at ALCOSAN before
being returned to the Ohio River.
• If you wash your car at home, try to wash
it in the lawn where the water can be absorbed or
filtered instead of flowing into the storm sewer
or onto a road. In many cases the driveway is acceptable
as well if the water from the driveway flows onto
the lawn. If you cringe at this water flowing onto
your lawn think about it going into streams!
Don’t let your
car, truck, boat, or motorcycle cause water pollution!
Don’t let your car leak fluids. One drop of
used motor oil can contaminate a million drops of
water. One quart of oil will contaminate 250,000
gallons of water or create an oil slick 2 acres
in size. Allowing your car to leak oils, antifreeze,
etc. creates a traveling water pollution machine,
fix those leaks!
• Perform your own oil changes, brake jobs,
or other maintenance in a garage or other sheltered
location where drips, leaks, spills, etc. cannot
be washed away by rain. A recent study found that
backyard mechanics in Michigan alone create more
oil pollution than the Exxon Valdez spill in Alaska.
make your lawn green at the expense of the environment!
• Avoid using herbicides (weed killers) and
fertilizers if you can. Simply mowing your lawn
at a taller height can result in deeper, stronger
roots, greener more drought resistance blades, and
can crowd out weeds.
• If you must use herbicides and fertilizers
look into less harmful natural options such as corn
gluten which is a natural, non-toxic weed
suppressor and slow release fertilizer.
• Get a soil test! Penn State will test your
soil for $9 via this
website or the Allegheny
County Extension Office. The same scientists
farmers rely on to manage their fields will provide
you a custom detailed report that will tell you
what fertilizer to buy and how much to use (i.e.
apply 1.75lbs per 100 square feet of 10-10-10 once
in fall and once in spring). This will save you
money, provide better results, and protect the environment.
• If you feel you must use them apply herbicides
and fertilizer in accordance with manufacturer’s
recommendations. Apply the proper amount at the
proper time to save yourself money, get the best
result, and save the environment.
• Don’t apply these chemicals when the
ground is frozen or before rains are forecasted.
• Be careful or use a spreader with “edgeguard”
to avoid spreading herbicides or fertilizer on sidewalks,
streets, or driveways adjacent to lawn areas where
the chemicals will get washed into the storm sewers.
Do not blow leaves or lawn clippings onto the road
where they will be washed into the storm sewers
and ultimately to the creeks and streams. This organic
material depletes oxygen in water and can cause
algae blooms that harm fish and other organisms.
