Wet Pond Maintenance Requirements
Important operation and maintenance proce
Immediately after the wet detention basin is established, the plants on the
- vegetated shelf and perimeter of the basin should be watered twice weekly if
needed, until the plants become established (commonly six weeks).
No portion of the wet pond should be fertilized after the initial fertilization that is
required to establish the plants on the vegetated shelf.
Stable groundcover will be maintained in the drainage area to reduce the
sediment load to the wet pond.
If the pond must be drained for an emergency or to perform maintenance, the
- flushing of sediment through the emergency drain will be minimized as much as
At least once annually, a dam safety expert will inspect the embankment. Any
- problems that are found will be repaired immediately.
The measuring device used to determine the sediment elevation shall be such
that it will give an accurate depth reading and not readily penetrate into
