Stormwater is water that originates as precipitation events and collects or flows over land.
Stormwater and Pollution
During heavy rain events, the raindrops flow together (creating stormwater runoff) and pick up pesticides, fertilizer, oil and grease, pet waste, gravel and sediment, litter and other pollutants as it flows across the grass and/or pavement. If the flow is slowed, the water is absorbed into the soil and can filter and replenish groundwater. In a heavy rain event, or when the stormwater flow is high and not absorbed, the excess water flows into a storm drain and a network of pipes that lead to a ditch, stream, river, or lake.
The City of Tuscaloosa, construction companies, industries, and others use stormwater best management practices (BMPs) to protect local and natural resources. These BMPs filter out pollutants and/or prevent pollution by controlling it at its source.
All storm drains lead to local bodies of water. Stormwater is not treated at water treatment plants.
