Stormwater Runoff

Stormwater runoff is rain that runs through our yards, streets and parking lots, picking up pollutants along the way. The runoff then enters our storm sewer system, which flows directly into our major water bodies.

runoff from the roof, yard, gutter, driveway, and street contain harmful substances like fertilizer, motor oil or pet waste the flow through the storm drain and into local streams, creeks, rivers, and the bay.

Only Rain Down the Drain

Pinellas County code prohibits pollutants from entering surface waters, the drainage system or roads leading to storm drains. Additionally, no connection can be made to the storm sewer without proper permits.

Pollutants include yard debris, oil or other automotive fluids, sediment, gravel, masonry materials, paint or any other chemical.

Exemptions include discharges from potable water sources, firefighting activities and non-chlorinated pool discharges.

Specifics are covered in the Pinellas County Code of Ordinances, Article VI, Stormwater and Surface Water Pollution, Section 58.
