Q. FDDs remove stormwater flow from the sanitary sewer system and redirect it to the storm sewer system. What if the storm sewer system is already at capacity?

A. When the storm sewer system reaches its capacity, storm water flows onto ground surfaces, such as roads and yards. Once the flow that had filled the storm sewer passes, the surface flow (the water in roads and yards) will enter the storm sewer. In homes with a sump pump, there is a pipe outside the home, constructed with an air gap. The air gap allows the flow to drain onto the ground, if the discharge line is full.
