Preventing Stormwater Pollution
Rain and melting snow (also called stormwater) can pick up trash and other pollution from our lawns and streets and carry it to our creeks and streams. This pollution eventually makes its way back to the Cumberland River, the source of our drinking water.

How the Stormwater System Works
Nashville's stormwater system is made up of street drains, pipes, and ditches that lead to our natural waterways. Rainwater that does not soak into the ground is directed to a ditch or to a stormwater pipe to minimize street and yard flooding in our neighborhoods.
Ditches allow rainwater to soak into the ground or, if there is too much rain, the water flows down the ditch to a creek or stream. Storm drains and pipes send excess rainwater, or runoff, directly to these waterways.
When brush, yard waste, and other debris is left in the ditch or on storm drains, it will act like a dam and prevent water flow. When ditches and pipes become clogged, your yard, your neighbor's yard, or even your street may flood. Public Works offers some simple guidance for setting out brush for collection.
Remember, only rain belongs in the drain.
