Domestic Wastewater Program

Vessel Discharge

The discharge of untreated "sewage" from boats into waters of the state is prohibited by both state law (Florida Litter Law - 403.413, F.S.) and federal law (Clean Water Act). Note, graywater is not considered "sewage" in the law. Therefore, the discharge of graywater from boats into the sea around Florida is currently not prohibited. The law defines graywater from boats as "galley (kitchen), bath, and shower water."

Capacity vs Flow

One question that is frequently asked by individuals reviewing domestic wastewater treatment facility data is:

What is the difference between capacity and flow?

This short article provides guidance on the significance and use of these terms.

Flow

“Flow” is the easier of the two terms to grasp. It simply is the actual amount of water flowing by a particular point over some specified time. In most cases, we report flow in terms of millions of gallons per day. You will see this unit of measurement abbreviated as “MGD.”
