What is allowed into storm drains? What happens when water is discharged from a fire sprinkler system?
Legally, only storm water may enter the storm drain system.

When water is discharged directly from the fire sprinkler system and flows along the parking lot, it picks up urban pollution, such as oil, grease, sediment, trash, brake dust, etc., which will flow with it into the storm drain system.

Storm drains are not connected to sanitary sewer systems or treatment plants. The primary purpose of storm drains is to carry rainwater away from developed areas to prevent flooding. Disposing of materials into storm drains, either directly or indirectly, causes serious ecological problems — and is prohibited by law.
