Property owners in Maryland, Virginia, and Washington, DC, are often responsible for stormwater management. This means you may have to choose between a detention or retention pond when planning your new construction project. These basins sit below ground level and collect stormwater runoff to prevent flooding and erosion.
In this article, we’ll discuss the differences between detention ponds and retention ponds, along with when each type of stormwater basin is more appropriate. Once you know which is best for your property, you can work with a local stormwater management company to set up the installation process.
Detention ponds, or detention basins, typically use a slight slope to divert stormwater runoff into a spacious collection area. There are outlets in the basin that gradually release water until the detention pond is drained. Detention ponds:
Are designed to be dry when not in use
Do not improve the quality of the stormwater
May be hidden under other structures, like parking lots
Require a lot of space and work best on large sites
Need routine maintenance to remove sediment and debris
Retention ponds contain and treat contaminated stormwater to remove pollutants. Unlike detention ponds, they are not meant to drain over time and instead will evaporate or soak into the ground. Retention ponds:
May be used as a wildlife habitat
Don’t require extra equipment to remove pollutants
Are suited to both large and small sites
Are considered low-impact on the environment
Require less maintenance than detention ponds
Which Stormwater Basin Should You Choose?
Are you still unsure whether to install a detention or retention pond on your property? Here are some takeaways:
You should choose a detention pond if you have a large site, don’t require water treatment, and would like the stormwater your basin collects to drain more quickly.
You should choose a retention pond if you prefer an environmentally friendly stormwater basin that serves as a natural habitat, removes pollutants from the water it collects, or have a smaller site than a detention pond requires.
A professional stormwater management company can help determine which stormwater basin is right for your property.
