If well-maintained, retention ponds can add significant value to a commercial property. Better water quality – Detention ponds are designed to fill and empty quickly, but retention ponds allow sediments and pollutants to settle at the bottom. This naturally improves water quality, and pond-dwelling vegetation also helps the process along.Detention basins let run-off spread across a wide floor area and only fill after heavy rainfall, when they will hold large volumes of water. This lets pollutants settle out before the water soaks away or discharges slowly downstream. Ponds and wetlands. If you want to store water for longer, you can use ponds instead of detention basins.

There are two types of basins, dry detention ponds and wet detention ponds, also known as retention ponds. The biggest difference between the two is that a detention pond will remain dry until a storm occurs, and a retention pond will have a constant pool of water. Both dry detention and wet detention can be planned in a good … Detention ponds gradually release stormwater through an outlet structure to adjacent surface waters rather than through infiltration into the soils.
