Evaluate the effectiveness of Low Impact Development (LID), green infrastructure and other best management practices for reducing wet weather pollutant loadings. LIDs are integral to new development design and are also being widely retrofitted into existing developments.
Low Impact Development (LID) is an increasingly popular alternative to "end of pipe" solutions. LIDs are designed to intercept, store and/or infiltrate precipitation before it reaches the conveyance system. LIDs are becoming an integral part of new development design and are also being retrofit into existing developments in order to promote infiltration, reduce storm water runoff and improve receiving water quality.
PCSWMM streamlines the modeling of LIDs on either a detailed, lot-level scale, or on a subwatershed or watershed scale for planning studies. The deterministic approach models physical processes within various LID control devices.
Supported LIDs include:
PCSWMM's capabilities for LID analysis include:
