Let It Soak In!

Each of us play a role in the health and future of our creeks and rivers.  Our actions, both negative and positive, can make an impact that can last generations! Being good stewards of our environment will protect the land we live on, which directly affects the health of our water. Polluted water in the San Antonio River harms more than just the fish and wildlife in our community.

Did you know that the San Antonio River is 240 miles long? Because of this, water from the San Antonio River has direct impact on the health of wildlife in the bay and the Gulf of Mexico.

Here are some simple steps you can take to help make a difference to our waterways in your community:

Impervious Cover

What is Impervious Cover and Why is It Harmful to Our Waterways?

Impervious cover does not allow stormwater to absorb into soil. This increases the volume and velocity of stormwater entering waterways, which leads to erosion. Pervious cover on land helps slow down polluted water, spread it out and soak it in.

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, about 6-9 inches deep, that captures rainwater from your roof, sidewalks and driveway. Pollutants that can become hazards to our waterways include bacteria from your roof, pesticides, fertilizers and oils from your driveway. The rain garden allows you to slow down the flow of stormwater entering our waterways, to soak up some pollutants and filter the runoff that would otherwise end up in the nearest storm drain, and ultimately in our creeks and rivers.

Interested in building your own rain garden in your home or office? We have a series of step-by-step videos to walk you through the process.

Pick Up After Your Pet

Why? 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.

Improve your Home

Did you know, in San Antonio, stormwater does not drain into a sanitary sewer system. It flows directly into our creeks and rivers. Visit this section of our website to discover simple modifications you can do at home that can help protect the San Antonio River Watershed.
