Stormwater begins as rain or snowmelt that falls on or washes over both pervious (grass, woodlands, gardens and other undeveloped lands) and impervious surfaces (roofs, driveways, parking lots, streets, and other hard surfaces). It flows from rooftops, through lawns, over paved streets, sidewalks and parking lots, across bare soil, and eventually flows untreated into storm drains to our streams, creeks and rivers.
Stormwater runoff is created from excess water that cannot be absorbed by pervious surfaces or from water flowing off impervious areas. Rather than being absorbed into the ground, rainwater enters the city's stormwater drainage system, a network of catch basins, yard inlets and pipes that keep water from flooding roads and property. Water is diverted through the network and eventually to the city's streams, rivers, and lakes. As it flows, runoff collects and transports pet waste, soil, pesticides, fertilizers, oil and grease, litter, and other pollutants. These materials carried with the stormwater are called non-point source pollution, and are some of the largest sources of pollution to our water. Because stormwater has the potential to pick up pollutants as it crosses over the land, its protection is vital to the health of our environment and our drinking water.

You Can Protect Our Waterways
Report Illegal Dumping. If you have witnessed illegal dumping in the City of Grand Prairie or know of a location where illegal dumping has occurred, please call the Illegal Dumping Hotline at 972-237-8064.
Remember to turn off your sprinklers when it rains to avoid water runoff; during winter, runoff can freeze causing slippery conditions. No matter how much you water it, concrete will not bloom! Prevent runoff and save the water for your plants!
Bag your pet’s waste – don’t just leave it there. Leaving pet waste on the ground increases public health risks by allowing harmful bacteria and nutrients to wash into the storm drain and eventually into local waterways. Don’t apply pesticides, fertilizers and herbicides before it rains. Contrary to popular belief, the rain won’t help to soak these chemicals into the ground; it will only help create polluted runoff into our local creeks.
Select native and adapted plants and grasses that are drought and pest resistant. Native plants require less water, fertilizer, and pesticides. Learn more about native and adaptive plants at www.txsmartscape.com.
Reduce the amount of paved area and increase the amount of vegetated area in your yard. Vegetation can help act as a natural filter for polluted stormwater runoff.
