Why Some Ponds Fail…
Poor maintenance is the leading causes of pond failure. A poorly maintained detention pond can lead to unpleasant odors, nuisance insects rodents, and becomes an unsafe area.
Detention ponds can fail for several reasons such as:
- Poor vegetation maintenance such as out of control weed growth or too little mowing
- Clogged inlets or outlet resulting from trash and debris, and sediment accumulation
- The excess build up of silt
- Failed side slopes of the embankment (Erosion)
- Inadequate access to the pond which complicates routine maintenance activities.
Definitions:
Dry Detention Pond – A pond designed to temporarily detain stormwater runoff and to release it over a period of time, generally no more than 72 hours, designed to NOT have a significant permanent pool of water
Emergency Spillway – Conveyance feature of a detention pond to discharge excess stormwater flows to maintain the integrity of the pond structure during substantial runoff events.
Orifice – A controlled opening on the outlet structure through which stormwater is discharged from the pond.
Outlet – A structure that controls the rate of release from the pond, the water depth in the pond, and storage volume of the pond.
OCS – Outlet Control Structure
Regional Pond – A pond designed to capture stormwater runoff from a large regional area.
Rip Rap – Rock material, generally larger than 4″ in diameter, typically used to stabilize channels that convey stormwater.
Riser – A vertical pipe which can function as the outlet structure of a pond. One or more openings are located in the riser to control the flow out of a pond.
Trash Rack – A structural feature of the outlet that prevents large trash and debris from clogging or blocking the outlet.
Water Quality Pond – A detention pond with an orifice sized to allow time for settling and filtering of pollutants before the runoff is discharged from the pond.
Wet Detention Pond – A pond designed to have a permanent pool of water after a storm event.
