Detention Ponds: Do they really need to be maintained?
Detention ponds have become one of the most common solutions for stormwater management. They do a great job of slowing runoff, containing sediment, collecting trash, and removing pollutants. More often than not, they are cost-effective and provide a little bit of nature in a common concrete jungle.
Ponds, like the one pictured above, are highly effective at moving stormwater runoff at the speed and the direction desired by the property owner and the surrounding neighbors. These types of ponds are created to present a natural feel to the property. It’s a great place to take a walk around or sit on an adjacent bench and enjoy a sack lunch.
Because these types of ponds are visual focal points in the design of the building, the landscaping and maintenance are done regularly to insure a pleasant and functional pond.
However, many detention ponds are located towards the back of properties. The owner wants it to perform its duty, but prefers that it be out of sight. These are the ponds that are often neglected. Out of sight can often lead to out of mind.
These ponds are often denied the most basic of maintenance programs. Things like mowing, trash and litter clean up; removing sediment and slope stabilization are ignored when there is not a plan in place. Bringing a neglected pond up to standard can be a huge, unexpected expense as well as an environmental disaster. Failures within the pond and damages to downstream properties can run into the hundreds of thousands of dollars. And don’t forget about the attention from local government entities that a failed pond brings with it.
On the other hand, these shocking costs and government scrutiny can be avoided by merely applying regular inspections and routine maintenance to your pond.
Regular inspections performed by a certified professional will see to it that the required maintenance is being completed. The inspector will catch failures and required repairs early in their development. This makes for a much less expensive repair than waiting until someone downstream has property damage due to your failed pond.
What does a professional look for when performing an inspection?
- Clogging or obstructions of outlets due to trash, debris or excessive sediment.
- Erosion on the slopes or head wall.
- Excessive vegetation in and around the pond.
- Clear and open pilot channels.
- Functionality of mechanical devices (pumps, flood gates, etc.).
- Condition of inlet and outlet pipes.
- Identify anything negatively affecting the pond’s designed performance.
What type of maintenance is required for a detention pond to function properly?
- Mowing, trimming and keeping vegetation under control.
- Keeping the pond clear of trash and debris.
- Maintaining mechanical elements in and around the pond.
- Stabilized slopes.
- Removing excess sediment from the basin, outflow and inflow pipes.
- Maintaining a detention pond is not complicated, it just needs to be done regularly and properly. The benefit of maintenance is a low cost and often attractive stormwater management feature that will work for you and the surrounding community for years to come.
