How do drainage ponds work?
John Wick
Drainage ponds are one solution to the problem of stormwater. These ponds collect stormwater as it runs off from the watershed, and they release them at a predetermined and slower rate via a low-flow orifice to avoid causing damage to the surrounding environment. Drainage ponds, which are designed to contain water at all times, are similar to detention ponds, which are designed to let water flow out until they’re completely dry. In terms of construction, that difference means that detention ponds have their orifice at the bottom of the pond, while retention ponds have higher outflow points that allow some water to remain in the pond at all times.

Drainage ponds detain Drainage in order to prevent flooding and minimize erosion. They do so by collecting runoff in a basin of a predetermined volume. The basin is designed to fill with water during the storm and discharge the water through an outlet structure which releases water at a rate similar to the rate of flow before the watershed was developed. To capture runoff, each Drainage pond must have an empty space that can fill with water during the storm. The empty space from the normal water level to the top of the bank slope is known as the temporary storage capacity.

The system works by allowing a large collection area, or basin, for the water. The water then slowly drains out through the outlet at the bottom of the structure. Sometimes concrete blocks and other structures act as a deterrent to slow the water flow and collect extra debris.
