Runoff is the most significant contributor to water quality degradation and biggest threat in the San Antonio River Watershed. Water that goes into storm drains is not treated before it reaches water bodies. This water is known as stormwater runoff or non-point source pollution.

Here are 5 things you can do now to protect the creeks and rivers in your neighborhood:

1. Turn Your Downspouts

Check out the rainfall during a storm. Does your home have gutters and downspouts that direct roof runoff onto hard surfaces? If so, you can redirect the downspout to your lawn or landscaping to help filter the water before it reaches the storm drains.

2. Build a Rain Garden

A rain garden can help beautify your yard and help protect the environment. Think of the garden as a shallow bowl, that captures rainwater from your roof, sidewalks and/or driveway. The rain garden allows you to slow down the flow of rain water entering our waterways, to soak up some pollutants and filter the runoff that would otherwise end up in a storm drain, and ultimately in our creeks and rivers. This will help protect you foundation. Look for areas that are 10 feet from the foundation to build your rain garden. We have a short series of step-by-step videos to walk you through the process.

3. Add a Rain Barrel or Cistern to Your Yard

Harvest rainwater in a rain barrel or a cistern and use that water to irrigate your yard. This will help capture water and conserve potable water that is typically used to water lawns.

4. Pick Up Your Pet’s Waste

Animal & pet feces that are not picked up can also end up in storm drains and travel to nearby creeks and rivers. Feces carry bacteria that cause disease. Help do your part by picking up after your pet waste and properly disposing it in the trash.

5. Permeable Pavers
Permeable Pavers

Permeable paved areas transform pavement into a stormwater treatment device. Permeable paved areas have gaps between the pavers which allow stormwater to drain to a gravel and sand reservoir below. The runoff is filtered through the reservoir before entering the storm drain system. Layers of sand and stone filter runoff to remove pollutants before releasing the runoff of the property.
