Stormwater Vs. Sanitary Sewers

You very well may be asking yourself... how did I end up at the Stormwater Division website on my search to learn about Orlando's lakes!?  Well, Florida is unique in many ways including how its sewer systems are built.

Here in Orlando there are two completely separate systems;  the sanitary system and the stormwater system.  The sanitary sewer systems carry any wastewater from your home or business (toilets, tubs, sinks, dishwashers, washing machines, etc.) by connected underground sanitary sewer pipes.  These pipes eventually end up at a wastewater treatment facility where it undergoes complex treatment until it is safe to discharge.  Stormwater, on the other hand, enters underground storm pipes through a stormdrain or curb inlet, which is completely separate from the sanitary system.  The stormwater within these pipes drains directly into a nearby lake and in most cases does not undergo any type of treatment. 

Stormwater runoff is defined as the water from rain that flows over the ground or pavement without soaking into the ground.  Buildings and pavement that cover the land’s surface decrease the pervious ground, which increases the quantity of stormwater runoff and our reliance on stormwater systems to carry urban runoff to our lakes.  Anything in our streets, driveways, parking lots, alleys, and sidewalks can end up in a nearby lake whenever it rains.

The stormdrains or curb inlets pictured below are the common structures found throughout Orlando in which stormwater enters.  They are found within our neighborhood and City streets and parking lots.  Anything that makes its way into these stormwater drains will more than likely end up in a nearby lake!
