Retention ponds are an effective way to control drainage after a storm. If the stormwater runoff is a problem on your property, you may benefit from hiring excavating professionals to dig a pond. Know what to expect and the purpose they serve by seeing a few of the most common questions property owners have about these ponds.

Retention Pond FAQ

What is stormwater runoff?

Runoff is the water that comes off of driveways, roofs, sidewalks, roads, and other surfaces that don’t allow the water to soak into the ground. As the stormwater travels over these surfaces, it picks up the pollutants on them. This might include sediment, pesticide, vehicle oil, litter, and animal waste.

Why do you need to manage runoff?

Runoff water doesn’t receive any treatment, which means that it releases all the pollutants it picks up into aquatic ecosystems. The bacteria and pathogens may pose health hazards to the local wildlife, while other contaminants may be a food source that encourages unwanted growth. For example, it may create an algae bloom, which steals oxygen from fish in the waterway.

How does a retention pond manage runoff?

Excavating retention ponds are crucial to improving the quality of stormwater runoff and reducing its quantity. The basin filters the polluted runoff, so it naturally filters it before releasing the water back into the environment. It also holds onto the water during peak runoff times—during and immediately after a storm—so it doesn’t cause erosion or flooding.

What’s the difference between retention & detention ponds?

These are the two types of stormwater ponds or basins. A detention pond holds water temporarily after a storm so that it can reduce the peak rate of runoff to a storm sewer or stream. A retention pond holds water year-round, though its water level may fluctuate after storms.
