Stormwater runoff is managed separately from our sanitary sewer system which carries human waste and sewage through a series of manholes and gravity and force mains that connect to Miami-Dade Water and Sewer Wastewater Treatment Plant at Virginia Key. Find our more about both systems below.
In this section
Coral Gables sanitary sewer system consists of underground pipes that carry sewage from kitchens, sinks, bathroom, and other plumbing components to a wastewater treatment plant. There the waste is filtered, treated, and discharged. In Coral Gables, our sanitary sewer system carries our wastewater away from Coral Gables and connects to the Miami Dade County sanitary sewer system and ends up at the Virginia Key Wastewater Treatment Plant, where the County oversees its treatment. The City owns, operates and maintains the sanitary sewer system components within our City limits. For more information please see Miami Dade Water and Sewer Department

Stormwater runoff is generated from rain events that flow over land or impervious surfaces, such as paved streets, parking lots, and building rooftops, and does not soak into the ground. The runoff picks up pollutants like trash, chemicals, oils, and dirt/sediment that can harm our rivers, streams, lakes, and coastal waters.
Better Management Practices Tips
Rainy days in South Florida and in Coral Gables are very common, and if not careful, these downpours may result in stormwater pollution. As stormwater flows over driveways, lawns and sidewalks, it can pick up debris, chemicals, silt, and other pollutants. So, what can you do to help? There are some things that you can do to prevent stormwater runoff pollution. Stormwater may flow into a storm sewer system or directly into a lake, canal or coastal water. Polluted runoff is the greatest threat to clean water.
How to prevent stormwater runoff pollution:
- Minimize or eliminate fertilizer, herbicide and pesticide use (especially during summer months when rains are heavy) —or switch to organic varieties that are not harmful.
- Never dump anything down storm drains or into canals, lakes, or streams.
- Avoid over-watering your lawn.
- Compost yard waste.
- Sweep up debris.
- Direct downspouts away from paved surfaces and consider a rain garden to capture runoff.
- Take your car to the car wash instead of washing it in the driveway.
- Check your car for leaks and recycle motor oil.
- Pick up trash, pet waste and litter around your yard and home.
