Urban Storm Water Treatment and Analysis Software Results Released

Innovyze announced the second quarter 2015 release of InfoSWMM Sustain. Designed in response to the needs of watershed and storm water engineering professionals. The tool lets users develop, evaluate and select best management practice (BMP) combinations at various watershed scales on the basis of cost and effectiveness.

InfoSWMM Sustain is a comprehensive geocentric decision support system created to facilitate selection and placement of BMPs and low impact development (LID) techniques at strategic locations in urban watersheds. It can accurately model any combination of LID controls, such as porous permeable pavement, rain gardens, green roofs, street planters, rain barrels, infiltration trenches, and vegetative swales, to determine their effectiveness in managing storm water and combined sewer overflows.

Such capabilities can assist users in developing cost-effective and reliable implementation plans for flow and pollution control aimed at protecting source waters and meeting water quality goals.

It does so by helping users answer the following questions: How effective are BMPs in reducing runoff and pollutant loadings? What are the most cost-effective solutions for meeting water quality and quantity objectives? And where, what type, and how extensive should BMPs be?

By integrating ArcGIS 10.x with SWMM 5.1, InfoSWMM Sustain  expands on the USEPA SUSTAIN software to provide support to watershed practitioners at all levels in developing storm water management evaluations and cost optimizations to meet their program needs.

The software can automatically import any SWMM5.1, InfoSWMM or InfoWorks ICM model, then evaluate numerous potential combinations of BMPs to determine the optimal combination to meet specified objectives such as runoff volume or pollutant loading reductions. Both kinematic wave and full dynamic wave flow routing models are fully supported.

InfoSWMM Sustain can be used in developing TMDL implementation plans, identifying management practices to achieve pollutant reductions under a separate municipal storm sewer system (MS4) storm water permit, determining optimal green infrastructure strategies for reducing volume and peak flows to combined sewer systems, evaluating the benefits of distributed green infrastructure implementation on water quantity and quality in urban streams and developing a phased BMP installation plan using cost effectiveness curves.
