Frequently asked questions (FAQs)

What is Autodesk XPSWMM used for?

Autodesk XPSWMM is a software application used for simulating hydrologic and hydraulic systems, aiding in stormwater and wastewater management, floodplain mapping, and river modeling. It enables the design and analysis of urban drainage systems, sanitary sewer networks, and natural watercourses, helping predict and mitigate flooding, optimize infrastructure, and ensure regulatory compliance. Autodesk XPSWMM supports integrated water resources management by evaluating watershed hydrology, pollutant transport, and the impacts of land-use changes and climate change. It is an essential tool for engineers, planners, and environmental professionals focused on sustainable and resilient water resource management.

Who uses Autodesk XPSWMM?

Autodesk XPSWMM is used by civil and environmental engineers, urban planners, government agencies, municipalities, consulting firms, academic researchers, utilities, and construction companies. These professionals and organizations rely on Autodesk XPSWMM to design, analyze, and manage stormwater, wastewater, and natural water systems. They use the software to predict flooding, optimize infrastructure, ensure regulatory compliance, and support sustainable water resource management and development planning.

What are the product tiers available for Autodesk XPSWMM?

Autodesk XPSWMM is available in two product tiers: XPSWMM Sewer and XPSWMM Complete.

 

XPSWMM Sewer includes:

  • 1D modeling for sanitary sewer networks (excludes river analysis and 2D flood capabilities)

XPSWMM Complete includes:

  • Integrated 1D/2D modeling for stormwater and sanitary sewer networks

  • Capabilities previously available in Innovyze XPStorm

  • All former Innovyze add-on licenses for GPU and multiple domains

What is the difference between XPSWMM and InfoWorks ICM?

XPSWMM and InfoWorks ICM are both software solutions for modeling and managing water systems and infrastructure. InfoWorks ICM is the most advanced and highest fidelity storm, sewer, and flood modeling solution on the market. It allows the modeling of entire urban cities or regional systems if needed.      

 

One of the key advancements of InfoWorks ICM is that it supports terrain-sensitive meshing, unlike XPSWMM's fixed grid system, which saves time and improves model quality. Additionally, InfoWorks ICM handles large data sets and complex flow conditions more effectively across multiple catchments and provides more advanced analysis tools, including various infiltration methods and scenario management.
