Designed in response to the needs of watershed and stormwater engineering professionals, InfoSWMM Sustain performs very sophisticated hydrologic and water quality modeling in watersheds and urban streams and enables users to develop, evaluate, and select optimal best management practice (BMP), Low Impact Development (LID) and Sustainable Urban Drainage Systems (SUDS) combinations at various watershed scales on the basis of cost and effectiveness. It can be effectively used to evaluate complex decisions about green infrastructure selection and placement, performance, and costs for meeting flow or water quality targets or both. It also gives users the power tool they need to maximize water quality benefits, minimize stormwater management costs and combined sewer overflows, and protect the environment and public health.
New to Sustain 3.0 is the ability to have detailed cost information for all LID's, SuDS and BMP's. The file BMPCostsData.MDB (part of InfoSWMM Sustain 3.0) has the following tables
