What do you know about stormwater pollution?
Stormwater pollution is a growing concern that impacts our environment and communities. As rainwater flows over surfaces, it collects harmful pollutants, threatening local waterways and ecosystems. Understanding this issue and its impact is key to safeguarding clean water for future generations.
What is stormwater pollution?
Stormwater pollution can result from contaminated runoff from urban areas as it drains from streets or property through the municipal stormwater drainage system and into our waterways (bayous, channels, ditches, etc.). The contaminated stormwater may affect waterbodies we use for fishing, swimming and providing drinking water.
What pollutes a stormwater drainage system?
What’s the difference between a stormwater drainage system and a sanitary sewer system?
In our area, the sanitary sewer system and the stormwater drainage system are two separate systems.The sanitary sewer system collects household wastewater from toilets, showers and sinks. The wastewater is sent to a treatment plant prior to discharge to the receiving stream. In contrast, stormwater is not usually treated and may carry contaminants directly into our waterways.
How can I help prevent stormwater pollution?
- Buy only the amount needed.
- Clean up spills immediately. Follow the directions on the product’s label.
- If possible, purchase nontoxic, biodegradable and/or recyclable products.
- Dispose of unused portions and containers properly.
- Do not over-fertilize near ditches, streams, or other water bodies.
- Don’t fertilize or apply pesticides before an expected rain – the chemicals may wash away into the stormwater drain.
- Store pesticides, fertilizers or other chemicals in a covered area to prevent contamination of runoff.
- Choose the most effective but least toxic product, such as dehydrating dusts, insecticide soaps, etc.
- Dispose of unused portions and containers properly.
What if I see someone throwing trash into a storm drain or ditch?
The sole purpose of a stormwater drainage system is to transport stormwater to the nearest waterway. Dumping trash, pollutants and debris into the storm drain is illegal and is a violation of the Clean Water Act.
