Detention basin retrofits

Retrofitting existing detention basins for water quality control can be a simple, cost-effective way of treating nonpoint source pollution. Retrofits are usually designed to promote infiltration and release less water from the basin. This might include planting or re-grading the basin area, or modifying the outlet structure that controls the release of water. This video shows some great examples of the retrofit process for several different basins. Although shot in Pennsylvania, the basic concepts are applicable for Connecticut. (Source: StormwaterPA).
