Is it OK to use fountains or aerators in stormwater ponds?
The purpose of stormwater ponds is to allow sediment from stormwater or runoff to settle out of the water. These ponds are then cleaned out when they are filled at least 50% with sediment. Yearly inspections are required to determine the amount of sediment in the pond. The circulation created by aerators and fountains does not allow sediment to settle out of the water properly. Therefore, while fountains and aerators may have other water quality benefits, they should not be used in stormwater ponds, which were built for the purposes of settling sediment.
