Stormwater Pollution Prevention

The DPW’s Division of Roads inspects and clears obstructed sewer lines, cleans catch basins and repairs broken lines.

Municipal Stormwater Pollution Protection Plan for the Township of Ewing, June 2005

What is Stormwater Pollution?

Stormwater runoff is water from rain and melting snow. It travels along gutters and flows over lawns, as well as driveways, parking lots and other impervious surfaces. It flows into storm drains and catch basins and through storm drain pipes and ditches. It eventually ends up in local waterbodies. It usually is not treated and along the way may pick up trash (fast-food wrappers, cigarette butts, Styrofoam cups, etc.) and toxins and other pollutants (gas, motor oil, antifreeze, fertilizers, pesticides and pet droppings). This polluted stormwater can kill fish and other wildlife, destroy wildlife habitat, contaminate drinking water sources and force the closing of beaches because of health threats to swimmers. See Cleanwater NJ FAQs.

Human activity is largely responsible for stormwater pollution. Everything that we put on the ground or into the storm drain can end up in our water. Each of us has a responsibility to make sure these contaminants stay out of our water. Whether we have clean water is up to you.

Why Has Stormwater Runoff Become Such a Problem?

Increasing commercial and residential development has a great impact on local water resources. The more impervious surfaces there are such as roads, rooftops, parking lots and other hard surfaces that do not allow storm water to soak into the ground, the greater the rate of stormwater runoff. This means a greater volume of water carrying pollution into surface waters and less water soaking into the ground. Less water soaking into the ground also lowers ground water levels, which can dry up streams and hurt stream ecosystems, and can reduce the supply of well water.

Stormwater also erodes stream banks. This in turn degrades habitat for plant and animal life that depend on clear water. Sediment in water clogs the gills of fish and blocks light needed for subsurface plants. The sediment can also fill in stream channels, lakes and reservoirs, covering the bottom and negatively affecting flow, plants and aquatic life.


You can make a difference in your own backyard to help reduce stormwater runoff.

  1. Reduce impervious surfaces such as concrete and asphalt and use pavers and bricks where water can trickle down through the gaps to reach the ground.
  2. Grade all areas away from your house at a gentle slope so that water does not seep through the foundation. Once the water has been carried 10 feet from the house, the surface should be graded so that runoff is released gradually.
  3. Plant sod on bare patches in your lawn as soon as possible to avoid erosion.
  4. Divert rain from paved surfaces onto the grass or rain gardens
  5. Plant a rain garden of native plants, shrubs and trees that reduce the amount of fertilizer needed and provide a way for water to soak into the ground.
  6. Plant trees, preferably native varieties, to help reduce erosion. Their leaf canopies help reduce erosion caused by falling rain. They also provide surface area where rain water lands and evaporates. Roots take up water and help create conditions in the soil that promote infiltration.
  7. Install a rain barrel(s) to collect rainwater; the rainwater can later be used to water your plants and lawn.
  8. Motor Vehicles. Maintain your car properly so that motor oil, brake linings, exhaust, and other fluids don’t contribute to stormwater pollution. Car washing is also a pollution problem because many metals and automotive fluids are washed off with the soapy water, travel down the gutter collecting more street pollutants, then enter our storm water conveyance system and spill into our waterways and bays. Commercial car washes recycle the water and send it to a wastewater treatment facility.
  9. Keep storm drains clean. Never dump litter, pet waste, motor oil, etc. into the storm drains. Keep debris out of the street and away from the storm drains, especially during the leaf pick and brush pick up seasons.
