StormPrism DryWell performs best when combined with a StormPrism Detention system. The detention system acts as a settling chamber to keep sediment from entering the SPDW. The DryWell then enables the engineer to infiltrate stormwater into the best percolating soils often found at depths far below the detention system. When combined with the other StormPrism detention systems, the SPDW optimizes the infiltration capacities of the overall design.
