Retention pond vs detention basin.

R-Tank® detention/retention and infiltration systems are among the most efficient systems available to provide underground storage for stormwater runoff. After a rain event fills the R-Tank®, stormwater can be routed to the drainage system, infiltrate into the ground, or be recycled for rainwater harvesting.1. Retention ponds are designed to hold and slowly release stormwater runoff over an extended period of time. 1. Detention ponds are designed to temporarily store stormwater runoff and release it at a controlled rate. 2. Retention ponds are typically designed to mimic natural wetlands and provide habitat for wildlife. 2.Retention ponds, detention basins, constructed wetlands and bioretention cells have all been used to treat car park runoff.

1.3 On-site Detention and Retention Features Peak runoff reduction can be achieved through the implementation of on-site ABC Waters design features and structural detention and retention features, such as: - Detention tanks - Retention ponds/Sedimentation basins - Larger perimeter drains - Wetlands - Planter boxes - Bioretention swales

These detention basins are typically planted with a turf grass that is mowed on a regular basis. This creates large areas of habitat or resting places for nuisance wildlife such as Canada geese. Geese can defecate up to 1 ½ pounds of fecal material per day causing a mowed basin to become an increasing source of bacteria in the watershed.

There are two primary types of basins, and with that in mind, let’s compare retention vs detention basin solutions. What Is a Retention Basin? Retention is the act of retaining, and a retention basin or pond is a man-made reservoir intended as a permanent pool of standing water. A retention pond can serve a number of purposes.
