Ten things you can do to prevent stormwater runoff pollution
Every time it rains, stormwater is carried directly to our surface waters. That
means that stormwater pollution can have detrimental effects to our creeks,
ponds, and the Catawba River into which it drains. Stormwater can carry
sediment, trash, automotive fluids ie. Oil and antifreeze, class clippings, leaves,
yard waste, excessive fertilizers, animal waste, pesticides and anything else that
may be transported by moving water.
There are 10 things that we can do to help protect our natural environment:
1 . Never dump anything down a storm drain, ditches, or creeks
2. Take used oil, paint, and household hazardous waste to recycling centers
3. Use fertilizers sparingly and sweep up driveways, sidewalks and gutters
4. Redirect roof gutters to lawns. Natural areas or rain gardens
S. Take your car to a car wash instead of washing it on the driveway
6. Sweep up yard debris instead of washing it away
7. Use a compost bin to run yard waste into a useful gardening product
8. Replant bare areas to avoid soil erosion
9. Report spills, dumping or suspected water pollution
10. Clear clogged storm drains - blocked drains cause drainage problems

UTILITIES CONNECTION
Grass clippings and leaf litter are stormwater pollutants. Yard debris, including leaves and other organic plant material like
shrubbery trimmings and grass clippings, are a significant source of stormwater pollution. When
K I INC you blow your lawn waste into the street it can clog storm drains and cause drainage and
flooding issues. Storm drains are not connected to the wastewater treatment plant. There is no
STRE TS treatment to remove the debris from the water before it reaches nearby lakes, streams, or the
river. Why are grass clippings and leaf litter harmful? As this waste breaks down in our local
BACK TO THE LAW: waterways, it adds excess nutrients like nitrogen and phosphorus to the water. This leads to
unwanted and uncontrolled growth of algae and native and non-native aquatic weeds. What can you do to help? Leave the
clippings on the lawn or compost them. Be sure to sweep or blow clippings off paved surfaces and back onto the lawn. If
you have any questions regarding Stormwater call 704-813-0251.

Utilities Connection
We all have waterfront property! Anything — trash, leaves, grass, soil,
fertilizers, oil, antifreeze, pet wastes, etc. —that is carried by rainfall as it flows over
our streets and yards ends up in our creeks and ultimately the Catawba River. The
purpose of drainage systems is to prevent flooding after rainstorms by quickly
diverting rainwater to local waterways. When storm drains and ditches are clogged
or polluted, they can increase flooding, and harm our local waterways.
Remember........ Clean water starts with you! Please contact the 5tormwater
Department at 704-951-0074 ext 1008 should you have any questions or concerns.

YrIMISCONNICTION
WHAT IS STORMWATER POLLUTION?
PnE�ut�nt�r k-=
One of the main things is Vehicle maintenance. Without care, motor oil,
grease, and soapy water from washing cars can end up in our storm
drains and water supply where they can make people and animals sick,
Just one quart of used motor oil can pollute 250,000 gallons of drinking
water, Never allow these pollutants to go into the street or storm drain,
and always dispose of them properly. Please contact our Stormwater
Department at 704-813-0251 with any questions or concerns.

Prevent Stormwater Runoff Pollution
Every time it rains, storm water is carried directly to our surface waters. That means that storm water
pollution can have detrimental effects to our creeks, ponds, and the Catawba River into which it drains.
Storm water can carry sediment, trash, automotive fluids like used oil and antifreeze, grass clippings,
leaves, yard waste, excess fertilizers, animal waste, pesticides and anything else that gets in its way.
✓ Never dump anything down a storm drain or in ditches or creeks.
✓ Take used oil, paint and other household hazardous waste to recycling centers.
✓ Use fertilizers sparingly and sweep up driveways, sidewalks, and gutters
✓ Redirect roof gutters to lawns, natural areas or rain gardens.
✓ Take your car to a car wash instead of washing it on the driveway.
✓ Sweep up yard debris instead of washing it away.
✓ Use a compost bin to turn yard waste into a useful gardening product.
✓ Replant bare areas to avoid soil erosion.
✓ Report spills, dumping or suspected water pollution to 704-827-3931
✓ Dear clogged storm drains. Blocked drains cause drainage problems.

UTILITIES CONNECTION
It is that time of year again to begin cleaning up fall leaves. The City of
Mount Holly is reminding residents to dispose of leaves properly to prevent
build up along curbs and storm drains, which blocks Storm Water runoff
from entering drainage infrastructure. Should a large rain event occur, this
could lead to localized flooding. Please contact the city for more details
such as leaf pick up dates etc. 704-827-3931.
